Oxygen Monitors now Required for Nitrogen, Argon, Helium, and CO2 use in Denver

The Colorado city of Denver recently passed a new law that requires facilities that use insert gas to install oxygen deficiency monitors wherever these gases are used in excess of 100 pounds. Learn what the new law requires from businesses and how an oxygen sensor protects your employees, your business, and your peace of mind.

What Denver’s New Law Requires

The law specifically applies to Colorado commercial, industrial, or manufacturing facilities that use inert gases, including nitrogen, argon, carbon dioxide, and helium. Facilities covered by the new law include water treatment plants, laboratories, and food processing plants.

Fire suppression systems and medical gas systems are not covered by the Denver law.

Under the new law:

  • Inert gas storage tanks must be placed in approved locations, whether stored inside or outside of the building
  • Storage containers must be secured to prevent tip-overs
  • All valves and tubing used with the gas system must meet applicable standards
  • Gases must vent outside the building
  • All areas where gas is used must either have an oxygen deficiency monitor or continuous ventilation system, which keeps the oxygen levels in the room steady
  • Oxygen alarms should be visually inspected daily by trained staff members
  • Storage tanks, piping, and other parts of the system must be checked on a monthly basis
  • Tests of the system must be conducted regularly with either air or an inert gas

The Denver law sets out regulations for the type of oxygen deficiency monitor, plus where and how to use them. Acceptable monitors must be installed in any location where an inert gas leak could result in an oxygen deficient environment where public health could be at stake.

Oxygen detectors must be on an approved device list and directly connected to the electrical supply and fire alarm system for the site. The oxygen detectors must be permanently mounted to the wall at a height which is consistent with the given gas’s vapor density, so they can work properly. The devices must be located within their specified ranges of operation, in order to ensure the monitors can work as intended.

The law prohibits self-zeroing or auto calibrating devices, unless they can be spanned or zeroed to check that the oxygen monitor is working as it should be. All installed oxygen monitors must be calibrated regularly to ensure safe and reliable operation.

Alongside mounted alarms, companies must place signage that notifies employees of the oxygen monitor and gives instructions for what to do in the event of an alarm. Typical instructions tell staff to leave the building and call 911 if the alarm is going off.

Signs notifying employees of the risk for oxygen deficiency must be posted anywhere inert gas is stored or used.

To further protect employees, the Denver law mandates that gas be transported, filled, or moved only by qualified individuals who follow protocol. All equipment, including piping systems, must be inspected for competency and the organization must maintain records for a period of three years.

Why an Oxygen Monitor is a Practical Suggestion

Oxygen deficient environments occur when an inert gas, such as helium, nitrogen, or argon, escapes into the environment and begins to displace oxygen. Since these gases have no odor or color, there is no way that staff working in the room can tell something is leaking. As the oxygen levels fall, employees can experience confusion and respiratory distress, resulting in death by asphyxiation.

An oxygen monitor tracks ambient levels of oxygen and sets off an alarm when oxygen levels fall below the safe threshold, thus protecting employee safety. Since employees can both hear and see the alarm, they will know there is a problem even if they are operating loud equipment that overrides the noise of the sensor.

Oxygen monitors are simple solutions to pressing problems faced by organizations that rely on inert gases and want to mitigate their risk.

PureAire’s oxygen sensors are cost-efficient and high quality. They are designed with a zirconium sensor, which is capable of lasting for as long as 10 years. PureAire’s oxygen sensor is accurate in diverse environments, from storage freezers to basements. The sensor functions between -40 and 55 C. While PureAire’s oxygen monitors do not need to be calibrated, they are capable of calibration, thus eligible for use in Denver.

PureAire’s monitors need little maintenance to work reliably once they are installed using the included wall-mounting brackets, and they are not affected by changes in the barometric pressure, a known problem with other types of oxygen sensors. PureAire’s products can be set to measure oxygen levels of either 18 percent or 19.5 percent (which is the OSHA action level), to comply with standards.

Use of Oxygen Monitors for Nitrogen, Argon, or Cryogenics and Where They Are installed

An oxygen deficiency monitor or O2 monitor is found in many settings where colorless, odorless gases — including nitrogen, argon, CO2, and cryogenic gases — are used. Always monitoring, the oxygen detector can tell when gas levels rise above those deemed safe, and let off a timely alarm. Learn which settings commonly use an O2 monitor, how the monitor works, and why it is beneficial.

How Does an Oxygen Deficiency Monitor Work?

With the name of oxygen monitor, you might wonder why these devices are used in the presence of other gases, such as nitrogen. Gases like nitrogen and argon deplete oxygen from the environment. If you introduce nitrogen into a lab setting, for example, oxygen levels start to drop. Since nitrogen does not have a color or scent, lab workers would be unable to perceive the leak.

As oxygen levels fall, lab workers would become confused and experience respiratory difficulties and loss of coordination. In a matter of minutes, lab workers could die from asphyxiation.

When an oxygen deficiency monitor is installed, it becomes easy to tell when a potentially hazardous gas has escaped into the room and is depleting levels of oxygen. Set to go off when oxygen falls below safe breathing levels, the O2 monitor flashes an alert and sounds an alarm to provide immediate notification. This way, staff have enough time to safely clear the premises before experiencing negative health effects. These monitors offer a cost-effective way to protect staff and maintain a safe working environment, and are a best practice for working environments that use these gases.

Where Oxygen Monitors Are Installed

Since oxygen monitors protect against a range of gases, they are used in many different industries and working environments. Some of the places that use oxygen monitors include:

  • Laboratory settings – As the example above indicates, lab workers often directly work with potentially dangerous gases in study, research, and teaching. An oxygen monitor in the lab setting operates as discussed in the example above, alerting workers if gases leak. Laboratories are required to install these devices by the 2008 NIH Design Requirements Manual as well as existing OSHA regulations.
  • Colleges and universities – Since universities have laboratories and work with these gases in teaching and research environments, it should come as no surprise that they have oxygen monitors. In the university setting, these monitors may be installed in classrooms, labs, research facilities, and storage areas to protect students, staff, and facilities workers. As this example illustrates, it is important to use a separate oxygen deficiency monitor in any area where these gases are used or stored. From a leaky pipe to a faulty storage tank, gas could escape in many ways – always posing a health risk.
  • Medical settings – Hospitals and medical centers need to keep blood, tissue samples, and other supplies properly chilled so they can be used for patients. The cryogenic gases are an easy, inexpensive solution to the storage issue. Yet, anywhere these gases are being used, there is the risk for a leak. In medical settings, an O2 monitor may be used in hallways and individual rooms where nitrogen containers are held.
  • Food processing plants – It is common to use nitrogen gas in food processing plants as a safeguard against oxidation of food and beverage products. When oxygen enters the food packaging, it causes early ripening and spoilage. Thus, nitrogen gas helps to protect the food and allows for longer storage on the shelf. Since the gas is cheap, environmentally friendly, and easy to use, it is a common solution in the food processing industry. To protect food processing workers, it is critical to have an oxygen monitor evaluating levels of oxygen in the air in case of a nitrogen leak.

PureAire’s oxygen monitor contains a zirconium sensor, which performs reliably for up to 10 years. This long-lasting sensor makes our oxygen monitors a good investment for many industries. These O2 monitors are easy to set up, work in a wide range of temperatures, and require no maintenance once they are installed.

Argon Gas Fill for Windows: How it’s Made and Benefits of Argon Insulation?

The window industry is always searching for energy efficient improvements to windows. In recent years, inert gas fills between panes of glass have increased the performance of windows by reducing air leaks. Learn more about benefits of using argon gas in windows and unexpected risks of the production process.

Argon Gas Fill for Windows

Argon (Ar) is a colorless, odorless, and non-toxic gas. Ar makes up one percent of the earth’s atmosphere naturally. Alongside the more expensive krypton gas, it’s the most commonly used gas fill for windows.

Placing gas between window panes helps fill thermal holes in the building envelope through which air leaks out. During the summer, cool air escapes through the window so your AC needs to work harder to keep you comfortable. In winter, hot air escapes through thermal holes, so it takes more energy to keep you warm. Reducing thermal holes by replacing inefficient windows or replacing aged caulk creates a tighter envelope with less potential for air to leak.

Along with gas fills, energy efficient windows feature low-e glazing, which blocks solar heat from entering your home. Windows that have an argon or krypton gas fill and low-e glazing have a much higher R-value (the measure of insulation) than old windows. Money spent replacing windows will be recouped through lower energy bills.

During the manufacturing process, argon gas is pumped between the window panes. You may spot two tiny holes on the spacer inside the window — an entry hole for argon gas and an exit hole for oxygen.

As the argon gas enters the space between glass, it pushes out oxygen. This occurs because it is heavier than oxygen. This simple fact highlights one little-discussed risk of using argon in window manufacturing: hidden dangers posed by the inert gas.

When it is released into the atmosphere, argon gas displaces oxygen. If argon gas leaks during the manufacturing process, the air in the room will become oxygen-deficient. Since the argon gas is colorless and odorless, workers will be unable to detect a leak, and thus unable to escape before suffering respiratory problems.

When employees breathe oxygen-deficient air, symptoms from dizziness and confusion to respiratory failure set on, often within minutes. Disoriented workers may be unable to flee for safety and can suffer death via asphyxiation as a result.

Fortunately, window manufacturing plants can keep their employees safe by installing an oxygen monitor wherever argon gas is stored or used.

How an Oxygen Monitor Protects Employee Safety

An oxygen monitor, also known as an oxygen deficiency monitor, tracks levels of oxygen in the room. Once installed, the monitor takes continual samples of oxygen levels and provides a readout on a display screen, so you can check oxygen levels at any time. As long as there’s enough oxygen in the room, the monitor stays silent.

If oxygen levels fall below OSHA safe thresholds and employee health could be at risk, the monitor flashes a light and sounds an alarm to let employees know. Staff have sufficient time to evacuate the room before suffering adverse health effects. These simple monitors cost little and can save lives when installed in window manufacturing facilities. To enjoy the widest range of protection, install an oxygen monitor anywhere that argon gas is used or stored. Whether a gas leak develops in the manufacturing room or in your storage facility, it can have deadly consequences.

PureAire’s line of oxygen deficiency monitors feature a hardy zirconium sensor, which is capable of evaluating oxygen levels with no calibration for 10+ years. Since the oxygen deficiency monitor from PureAire is easy to set up, easy to use, and low maintenance, many companies prefer it over an O2 monitor that requires regular maintenance.


Storing Liquid Nitrogen in Laboratories: Which Safety Precautions and Sensors Will Protect your Employees?

Liquid nitrogen is frequently used in scientific research, chemistry classes, and even culinary arts nowadays. The substance is safe when properly stored, and as long as everyone follows safety protocols while handling the liquid nitrogen. As part of an environmental health and safety review (EHS review), learn safety considerations regarding storing liquid nitrogen in the lab setting.

EHS Review: Understand Liquid Nitrogen Risks

Liquid nitrogen is known for its cryogenic properties. It can freeze things incredibly quickly. This property also applies to people, so staff must take safety precautions when handling liquid nitrogen. Even seconds of exposure can damage skin and eye tissue, and may cause frostbite.

Staff should never transport liquid nitrogen in open containers. They should never reach directly into vats of the substance.

The main health risk with liquid nitrogen occurs when the liquid vaporizes into gas, which happens if it leaks into the atmosphere. Nitrogen expands in volume when it turns into gas, and depletes oxygen from the air. The gas has no odor or color, so there is no way staff can tell a leak has occurred without an alarm system. If a nitrogen leak occurs, oxygen levels will fall below safe thresholds. This causes severe cognitive and respiratory problems, as well as death by asphyxiation.

Liquid nitrogen, like other cryogenic liquids, needs a pressure-relief valve during storage. Without such a valve, internal pressure could cause the storage tank to explode. Liquid nitrogen should be stored in a room that has proper ventilation as a precaution around leaks. If a leak occurs, the ventilation system can help shunt gases outdoors, protecting the health of workers.

How to Protect Your Employees’ Environmental Health and Safety With an Oxygen Monitor

Facilities must install, calibrate, and maintain oxygen sensors to comply with safety policies regarding the storage of liquid nitrogen in the lab setting. These units act as a secondary precaution against the dangers of a nitrogen leak. An oxygen deficiency monitor or O2 sensor measures the levels of oxygen in the environment at all times. These devices provide labs with a cost-effective and reliable way to make sure there are no leaks in nitrogen storage areas.

For safety precautions, install one oxygen deficiency monitor anywhere liquid nitrogen is stored, handled, or used. These monitors mount to the wall quickly and provide continuous sampling of oxygen levels. As long as there is no leak, and the room contains enough oxygen, the monitors stay silent. If nitrogen leaked it would cause a decline in oxygen levels, eventually triggering an alarm and flashing light. The oxygen monitor would provide enough time for anyone working in the area to vacate the premises and avoid being harmed or killed.

While there are several styles of O2 sensor on the market, those from PureAire are preferred for their high quality and cost efficiency. PureAire’s O2 sensors feature zirconium, which lasts for 10+ years on average with no maintenance and no calibration. Once the monitor in installed, there’s nothing more that needs to be done. Since PureAire’s oxygen monitors are reliable once installed, and require less maintenance than the competition, they make it easier and cheaper for labs to protect worker safety.

University Environmental Health & Safety Departments: How to Handle Compressed Nitrogen and Cryogenics

An explosion at a university research lab in Hawaii last year highlights the dangers of working with compressed gas and the need for safety equipment on campus. Learn the dangers of working with compressed gas, how an oxygen deficiency monitor can help, and campus safety best practices.

Compressed Gas on Campus: Uses and Dangers

Compressed gases including nitrogen, argon, and oxygen are widely used on campuses. These gases have many practical and educational uses across educational institutions. While the level of risk varies across schools, a few examples will illustrate the benefits and the risks of using compressed gas on campus.

Argon gas is critical in the 3D printing process, which campus design, fine arts, applied arts, and sciences may use. Culinary programs may use liquid nitrogen for cooking and freezing, and chemistry labs may use N2 as well. Autoclaves, which sterilize equipment, are regularly used in scientific, medical, and industrial programs. Sports programs and physical therapy training programs may use cryotherapy for injury recovery. Cryotherapy chambers rely on nitrogen to chill the air. The chambers can turn deadly if a nitrogen leak occurs. These gases may be used by facilities personnel, researchers, faculty members or teaching assistants and students assisting with teaching labs. No matter which gas students are working with, they are at risk if the gas is not handled, used, stored, or transported properly.

As these few examples illustrate, there are many opportunities for dangerous leaks, explosions, or fires on campus if safety protocol isn’t followed. Many schools find the gases are not properly stored, which leaves everyone on campus in danger. A recent safety bulletin from the University of Rochester found that liquid nitrogen was stored without an oxygen sensor, poisonous gas was used with a fume hood that did not adequately vent hazardous fumes, gas cylinders were modified using unacceptable materials, and gas tanks were stored without protective chains, stands, and gas caps.

Why Schools and Universities Need an O2 Monitor

As the incident in the Hawaiian university lab illustrates clearly, compressed gases pose significant health risks in the university setting. Whenever safety protocol is not followed, the tanks are at greater risk of tipping, falling over, or leaking.

While the lab worker escaped with her life, many others have not been so lucky. A nitrogen (N2) gas leak causes death via asphyxiation in a matter of minutes.

Nitrogen gas is both odorless and colorless. If gas leaks from a canister, there is no way for passerby to tell. As the gas leaks, it lowers ambient oxygen levels below safe thresholds. When levels of oxygen in the air fall below 16 percent, people can experience adverse health affects. Additionally, university property can be damaged by fires or explosions.

All it takes it a couple of breaths of oxygen-deficient air for symptoms including confusion, dizziness, fatigue, muscular aches, lack of consciousness, and even death.

Given the clear dangers that these gases pose, universities and schools must take steps to protect their students and staff. Fortunately, there is an easy and cost-effective way to detect gas leaks and alert everyone before oxygen is depleted from the air: Installing an O2 monitor.

An O2 monitor, also called an O2 deficiency monitor, measures levels of oxygen in the air all the time. As long as the air has adequate oxygen, the monitor will stay silent. When levels fall below safe thresholds, the oxygen deficiency monitor will flash lights and sound an alarm. This way, everyone in the vicinity of the leak can escape without suffering adverse health effects.

An O2 deficiency monitor should be installed anywhere that these gases are used or stored. Universities and schools may wish to equip labs, storage facilities, equipment rooms, and hallways or corridors that connect storage rooms with labs or classrooms where the gas is used.

PureAire offers robust oxygen deficiency monitors that feature best in class construction. Made with zirconium oxide sensors, these monitors offer 10 or more years of maintenance-free performance once installed. These monitors can detect leaks of gases including argon, nitrogen, and helium. View PureAire’s line of oxygen deficiency monitors at www.pureairemonitoring.com.

Titanium Demand on Rise for Additive Manufacturing Printing: How it’s Made? Titanium Plasma Atomization

Plasma atomization is used in many applications, including 3D printing. First developed in 1998, this technique has risen to become the industry standard process for creating reactive metal powders suitable for 3D printing. Learn how plasma atomization works and why you need an oxygen monitor to stay safe with plasma atomization.

How Plasma Atomization Works

Plasma atomization is used not only in 3D printing, but in any circumstance where powder metallurgy is needed. Other uses include spray coating, cold spray, and metal injection molding.

To pulverize metal, wire is fed through a tube, then hit by three plasma torches capable of reaching temperatures of 10,000 degrees Celsius. As the wire liquefies and melts, individual droplets shear off and fall into a chamber filled with argon gas and cooled by water. When the drops of metal hit the argon, they solidify into spherical droplets. This process produces a fine, uniform metal powder. After the wire has been transformed into droplets, the powder is sieved to ensure uniformity. This is key to the success of the 3D printing process, which relies upon fine grade, uniform powder.

Titanium (Ti), Nitinol, Niobium, Aluminum, and other reactive metals and their alloys can all successfully be atomized through this process. Variables in the plasma atomization process allow workers to create droplets of different sizes, for different end uses.

PureAire offers an oxygen analyzer, which many 3D printing manufacturers utilize. This device helps monitor the levels of oxygen in ppm, from 0 to 1000, while the atomization process takes place.

It’s important to keep oxygen levels low while the Ti and other base metals are being turned into powder, as this ensures the purity of the final product. Oxygen analyzers provide a continuous readout of oxygen levels inside the chamber, so your workers can ensure the highest levels of purity at a glance.

Argon gas is used during plasma atomization because it helps ensure the purity of the powdered metal by reducing the chance for chemical reactions that might happen if oxygen interacted with the metal during the atomization. As long as the argon gas remains in the chamber where the aluminum or titanium powder is being made, plasma atomization is quite safe. Like other inert gases, argon depletes oxygen from the atmosphere. Were the argon gas to leak out of the plasma atomization chamber, employees’ wellbeing could be at risk.

Why You Need an Oxygen Monitor with Plasma Atomization

When argon escapes into the environment, it displaces oxygen molecules. Since the gas is both odorless and colorless, there is no way to detect an argon leak by sight or smell. If there are several atomization stations creating Ti or titanium powder at once, the risk increases exponentially.

Once oxygen levels begin to drop, worker safety becomes a concern. If oxygen levels fall below the minimum set by OSHA, workers can suffer respiratory and cognitive impairment. Symptoms include dizziness, confusion, fatigue, and shortness of breath. Even a brief exposure to an oxygen deficient environment can prove deadly.

Fortunately, an oxygen deficiency monitor can continually weigh oxygen present in the room, alerting staff before oxygen levels plunge below the OSHA threshold. This provides sufficient notification via flashing lights and loud alarms for staff to exit the room to safety.

PureAire offers an oxygen monitor with a zirconium sensor. Unlike other sensors, this lasts with no maintenance and no calibration once the O2 monitor is installed. The O2 monitor and oxygen analyzer, when used together, allow for precise manufacturing of powdered metals with low risk to workers. Businesses prefer PureAire products, which are low-maintenance, cost-effective, and reliable for 10+ years. Visit www.pureairemonitoring.com to learn more about our oxygen analyzers and monitors.


Nitrogen Refrigerated Trucks a New Trend? An Alternative to Diesel Powered Refrigeration

Thanks to technological innovations, the food distribution industry has a greener way to protect refrigerated food during transit: Nitrogen refrigeration. The existing system relies on diesel-powdered mechanical refrigeration units. Although these units are effective, they release significant levels of noise and air pollution. While the new innovations decrease emissions to safeguard the environment, there is a hidden health risk transportation companies must take into account.

How Liquid Nitrogen Refrigeration Works

The new system uses a liquid nitrogen system to cryogenically chill food. A storage tank mounted underneath the truck can be easily refilled when empty. Since the tank is stored outside the truck, the liquid nitrogen never comes into direct contact with the food.

To cool the refrigerated container, liquid nitrogen first passes through a heat exchanger. As the nitrogen moves through the heat exchanger, it evaporates. High-powered fans inside the container circulate the chilled air through the compartment, helping keep all food safely chilled below the temperature danger zone.

The traditional mechanical refrigeration system emits significant noise while in operation. Even when the truck itself is off, the refrigeration unit can cause as much as 80 dB of noise, which is roughly as much noise as a busy urban environment. This noise level exceeds the typical noise pollution levels in cities, thus limiting the hours when truckers can make deliveries. Additional downsides to the mechanical refrigeration system include reliance on harmful refrigeration chemicals and expensive maintenance and repair costs.

In contrast, the liquid nitrogen system falls beneath the noise pollution thresholds, so deliveries can be made at any time. This benefits both truckers and restaurants, grocery stores, and other businesses who may want to accept deliveries outside of business hours.

The liquid nitrogen system, or N2 system, also reduces carbon dioxide emissions significantly and does not use harmful refrigerants to keep food cool. Transportation companies who want to green their image or offer their clients increased flexibility will enjoy the liquid nitrogen refrigerant system for these reasons.

While the cryogenic system reduces costs and pollution associated with mechanical refrigeration, the N2 system is not perfect. Liquid nitrogen does pose a safety risk if it comes into contact with the food or the environment. If a truck rollover accident caused a nitrogen spill, for example, individual health and environmental dangers abound.

If the nitrogen gas seeps into the load chamber in the accident, it could turn the truck chamber into an oxygen deficient environment. Staff who opened the truck chamber to check on their load could become dizzy, pass out, and die within minutes of entering the oxygen deficient space.

The liquid nitrogen itself has cryogenic properties, which is why it’s been used to freeze off cancerous cells and warts. A worker cleaning up the spill must take precautions to avoid getting liquid nitrogen on their skin. In a worst-case scenario, an employee could lose a finger if it was immersed in liquid nitrogen.

How to Safeguard Truckers Against Liquid Nitrogen Dangers

An O2 deficiency monitor, also called an oxygen monitor, can protect employees from the dangers posed by liquid nitrogen. These monitors continually measure the amount of oxygen in the load chamber. When the cryogenic system is working properly, oxygen will naturally remain at safe levels and the alarm will stay silent yet vigilant. In the event that nitrogen gas leaks into the load chamber — due to a system malfunction or an accident – oxygen levels will start dropping. Once the environmental oxygen levels falls below OSHA thresholds, the oxygen monitor will flash and sound an alarm. This notifies staff that safety hazards exist, so they will not open the load chamber and enter an oxygen deficient environment.

Since staff can succumb to asphyxiation within minutes, the O2 deficiency monitor is necessary to monitor system performance and keep employees safe if anything goes wrong. Since nitrogen is invisible and odorless, employees have no other way to know whether the system’s operating as it should or whether there is an N2 leak.

Oxygen monitors from PureAire use zirconium oxide sensors, which provide reliable service for 10+ years. To learn more about PureAire products, please visit www.pureairemonitoring.com.

Neon Gas and Where it is Used. PureAire Oxygen Deficiency Monitors for Safety and Why a Monitor May be Required?

Neon gas has a range of uses in industry, including in the popular business signs advertising stores as open. Explore some of the less well-known ways to use neon and learn how use of the gas may require installation of an oxygen deficiency monitor to protect worker safety.

Uses for Neon Gas

Neon gas can be filtered from helium using activated charcoal in a low temperature environment, or through the selective adsorption method. Once filtered out, neon can be used in the manufacturing of television tubes, plasma screens, and more.

Ne or neon gas is used for advertising signs, as are other noble gases. Neon is also used for television tubes, plasma screens, wave meter tubes, inside lightning arresters, and with high-voltage indicators.

The gas itself has no color until an electric charge is applied that alters the structure of the Ne molecules. Neon gas only produces a reddish orange color light, so other inert gases are used to make other colors. In plasma screens, individual neon lights interact with phosphors within the screen to product the vibrant colors. This interaction allows neon to make other colors.

In its liquid form, neon is extremely cold, and can act as a stronger refrigerant than liquid hydrogen or helium. Thus, the gas can be converted to liquid for use in cryogenic health tanks or other applications. There are potential cryonics applications for neon as well.

In recent years, noble gases including neon have been used to detect fracking leaks. Neon can be tracked as it moved, illustrating the path of leaked methane from the frack site. Neon is a good choice for this purpose since it will not interact with other natural elements.

As one of the inert gases, neon has a low environmental impact. The substance cannot react with other substances in the environment, which could pose harm. Neon is naturally found in the earth’s environment in relatively low concentrations.

Neon gas itself has no color or odor naturally. The noble gas could seep into the environment in a manufacturing leak without anyone knowing what had happened.

How an Oxygen Deficiency Monitor Can Protect Workers From Neon Gas Danger

Like other inert gases, neon can act as an asphyxiant. This means that, if Ne leaks into the air, it begins to displace oxygen in the air. As oxygen levels fall, workers can experience confusion and respiratory problems. If employees do not evacuate in time, they can lose consciousness and die of asphyxiation from the lack of oxygen in the air. In extreme cases, this can happen in a matter of minutes before staff even have time to reach safety.

Since workers cannot see or smell the gas, they need a way to know when they are in danger of asphyxiation. Installing an oxygen monitor is one of these easiest ways to protect employees and provide early warning.

A wall-mounted O2 deficiency monitor continually checks the levels of oxygen in the air, to protect employee health. The monitor stays silent when everything is normal. As soon as oxygen levels fall below the threshold set by OSHA, the monitor will sound an alarm and flash colored lights to provide staff with clear notification. Workers can then evacuate before oxygen levels fall so low that they experience respiratory problems.

PureAire offers an O2 monitor built to withstand 10 years of use with no maintenance once it is installed. Oxygen monitors from PureAire contain zirconium sensors, which are accurate, efficient, and long-lasting. Simply by installing the right O2 monitor, businesses can protect their workers in environments where a noble gas is used.

Are You An OLED Display Manufacturer? Why PureAire Monitoring Systems May Be Your Next Partner

OLED — organic LED — is a top desired feature in smartphones, yet manufacturers do not have the production capacity needed to meet industry demands. Since OLED devices have stronger contrast, a faster response time, a better quality, and a lower cost, there are many reasons for consumers as well as manufacturers to embrace this trend. To build capacity needed to product OLED screens for smartphones without sacrificing employee safety, semiconductor plants need two devices: An oxygen analyzer and an oxygen monitor.

OLED Manufacturing and its Risks

A good display is one of the strongest motivators to purchase a device, such as a television or a smartphone. The superior quality the OLED devices deliver will be a major driver for consumers, if these screens can make it onto a wide array of device types.

Next-generation OLED screens can even curve or roll up, like a newspaper. Kateeva is a company worth noting, as they are advancing OLED displays with over 200 million raised since 2008, using their YIELDjet FLEX printing tools. Two years after its debut, Kateeva’s YIELDjet FLEX tool is the undisputed leader in the industry. Kateeva’s President & COO was named “Inventor of the Year” for 2016 by the Silicon Valley Intellectual Property Law Association.

At present, only a handful of smartphone screens come with an organic LED. Apple hopes to ship all iPhones with OLEDs by 2018, but some doubt that facilities will have enough production to meet demands. At present, there is only one producer, Samsung, who is on board to provide the OLED screens.

Efficient OLEDs are made using either an inkjet printing process or a process known as organic vapor phase deposition (OVPD). In the OVPD process, an inert gas (usually nitrogen or N2) is used as a “carrier gas” to transport the organics onto a substrate, where they can condense. Nitrogen is a popular choice because it is inexpensive, efficient, and reliable.

Nitrogen can be generated on-demand using a generator that distils air into its component parts. An oxygen analyzer can help ensure the purity of the nitrogen gas created by measuring trace amounts of oxygen in ppm. By using nitrogen as the carrier gas, manufacturers can reduce the cost associated with making OLED screens and decrease the time to production.

How an Oxygen Deficiency Monitor Protects OLED Employee Safety

Inert gases including N2 do not react with other substances. If the N2 used as a carrier gas were to seep out from the generator or from supply lines, it would start to deplete oxygen present in the atmosphere. Since nitrogen gas has no odor or color, staff would be unable to tell that a leak had occurred without something like an oxygen deficient monitor in place.

Within minutes of a leak, room oxygen levels would fall to below the minimum acceptable levels for oxygen. When this happens, anyone in the room would begin to experience respiratory symptoms, including mental confusion, loss of consciousness, and asphyxiation due to lack of oxygen. Accidents involving oxygen depletion are usually fast, serious, and frequently fatal.

An oxygen monitor is a low-cost, effective way to monitor levels of oxygen anywhere that inert gases such as nitrogen are used. A wall-mounted oxygen monitor tracks oxygen levels on a continual basis and sounds a loud alert should oxygen fall below the 19.5 percent oxygen threshold earmarked by OSHA, a threshold that provides employees ample time to evacuate before succumbing to symptoms of oxygen deficiency.

By installing an oxygen deficiency monitor anywhere nitrogen gases are used or nitrogen generators exist, manufacturers can safeguard their staff while taking advantage of efficiencies that allow cheaper manufacturing of OLEDs.

PureAire offers an oxygen deficiency monitors with a zirconium sensor, which is capable of withstanding 10 years of continued use. Because these sensors are long-lasting, they offer a good value compared to other types of sensors on the market. By installing an oxygen monitor to safeguard staff and an oxygen analyzer to protect the purity of the nitrogen gas, manufacturers can build capacity needed to meet the demand for OLED screens.

PureAire’s sensors are reliable, effective, and easy to set up. Once installed, they require no calibration to work. These monitors work in temperature extremes and remain reliable even when adverse weather affects barometric pressure.


Nitrogen Demand Increases for Semiconductor: How Safe Are You?

As users demand ever-smaller smartphones and better televisions, semiconductor manufacturing plants are tasked with developing new products faster and using new materials. Key to the continued success of the semiconductor industry are inert gases, which include nitrogen and argon. When used safely, both nitrogen and argon play a number of important roles within the semiconductor plant. Yet, these gases poses a health hazard for employees if a leak occurs.

How and Why Nitrogen is used in Semiconductor Manufacturing Plants

Nitrogen is used throughout the manufacturing process, from purging pumps to abatement. Nitrogen is also used in the process, especially now that fab size is growing. In a modern semiconductor manufacturing plant, as much as 50,000 cubic meters of nitrogen gas are used every hour.

To meet this demand, semiconductor manufacturing plants are installing nitrogen generators onsite. Generators mean a cheap, efficient, and always-ready supply of nitrogen gas to supply production.

As long as nitrogen gas is stored safely in the generator and used properly, there is no health risk. Yet if the generator or supply lines develop a leak, nitrogen gas can escape and deplete oxygen in the environment. Since nitrogen gas is both odorless and colorless, there is no way that staff can monitor their risk.

Along with nitrogen, argon gas is used in semiconductor manufacturing, most notable as a sputtering gas. Like nitrogen, argon gas depletes oxygen from the environment. Like nitrogen, the gas has no color or odor. In a closed area, the gas can deplete oxygen and cause respiratory problems and eventual suffocation.

How an Oxygen Analyzer Can Protect Staff Working in a Semiconductor Manufacturing Plant

If either nitrogen or argon were to leak into the plant, these inert gases would begin to deplete the levels of oxygen in the air. OSHA sets the oxygen threshold at 19.5 percent or less oxygen in the air. If oxygen levels fall below this, staff could suffer.

When oxygen levels fall to OSHA’s threshold, staff may show signs of confusion or fatigue. Since there are no warning signs that something is wrong, staff can fall unconscious before they can escape the oxygen deficient environment. Once unconscious, they asphyxiate.

It is critical for any workplace that uses these inert gases, including semiconductor plants, to monitor levels of oxygen in the air and alert workers if the ambient oxygen levels fall to the OSHA threshold.

By installing an oxygen monitor and an oxygen analyzer anywhere inert gases are used, manufacturers can protect the safety of their workers through continual oxygen monitoring and fast alert if oxygen levels fall. A wall-mounted oxygen monitor scans the atmosphere and measures the amount of oxygen from 0 to 25 percent, well above the safety threshold. As long as there is enough oxygen in the air — which there will be as long as there is no inert gas leak — the oxygen monitor will remain silent.

When oxygen levels fall to the OSHA threshold, the oxygen monitor will flash lights and sound an alarm, providing instant notification to workers. Staff can take notice and evacuate before negative health outcomes occur.

An oxygen analyzer measures the level of oxygen present in gas produced via nitrogen generator to ensure the purity of the gas for use in manufacturing. Oxygen analyzers are ideal for low level analysis and can measure from 0 to 1,000 ppm. Workers can check oxygen levels at a glance and ensure the nitrogen generator is working properly. When combined with the oxygen monitor for safety, the oxygen analyzer streamlines and safeguards the semiconductor manufacturing process.


Tunnel Freezing and Flash Freezing Food with Nitrogen: Oxygen Monitors and Why They May be Required

New developments in cryogenic freezing are transforming the frozen food industry by making it easier to freeze all sorts of items quickly while retaining the highest nutritional value. Cryogenic and tunnel freezers are easy to use, yet they pose a hidden health risk. Learn why you may need an O2 monitor if your frozen food manufacturing facility relies on cryogenic freezers.

How Cryogenic Freezers Work

Cryogenic freezers allow for continuous freezing of food, increasing output without requiring a large amount of space. Compared to mechanical freezers, which take longer to freeze products, they increase both the production and the quality with a low investment of capital.

In particular, cryogenic freezers are useful for freezing par-baked goods, which are partially baked before being frozen for storage. Par-baked items allow fast-food restaurants, supermarkets, sandwich shops, cafes, and other institutions to offer fresh, healthy baked goods without needing to bake from-scratch every day. For a commercial baking facility, investing in a cryogenic freezer is the best way to increase their output, grow their business, and become more profitable.

Cryogenic freezers work by using liquid nitrogen to quickly chill items to safe temperatures for frozen storage. As in any environment where liquid nitrogen is present, there is a danger of oxygen depletion and asphyxiation. Thus, it is always a good idea to have an O2 deficiency monitor present onsite to protect the health of employees.

One subset of cryogenic freezers, the tunnel freezer, uses a continuous freezing model of a conveyor belt, an injection system, and an exhaust system to vent gases. When the texture of the finished product is paramount, as in baked goods or seafoods, or when it’s necessary to flash freeze hot foods quickly, a tunnel freezer is the best way to maintain quality in the end product.

Why an Oxygen Detector is Necessary with Cryogenic Freezers

As mentioned above, cryogenic tunnel freezers rely on an inert gas, nitrogen, to flash freeze food items. Nitrogen is perfectly safe when used in the closed-loop freezer system and properly vented from the facility. However, if the exhaust system were to develop a leak, nitrogen gas could enter the manufacturing facility and start to displace oxygen from the air. Since nitrogen is colorless and odorless, staff would not notice the leak. In a matter of minutes, ambient levels of oxygen could drop so severely that staff could become disoriented, lose consciousness, or die.

Simply by installing O2 monitors wherever nitrogen gas is used or stored, you can monitor levels of oxygen in the air and ensure there is no risk of oxygen displacement from a nitrogen leak. In the event that nitrogen leaks into the environment, the O2 deficiency monitor will sound an alarm and flash lights to let staff know that oxygen levels have fallen below the acceptable threshold set by OSHA. Staff can then evacuate before their health is compromised.

There are many styles of O2 monitors, but the one we recommend for flash freezing environments is the Sample Draw oxygen monitor. The style of O2 monitor can be placed outside the freezer and monitor levels of oxygen inside the freezer using a polyurethane tube. This ensures the sterility of the flash freezing environment while safeguarding workers. With a state-of-the-art zirconium oxide sensor, this style of oxygen detector can last without any maintenance for up to 10 years.


A Nitrogen Culinary Experience and How to Remain Safe with Use of Oxygen Monitors

As modernist cuisine has become more popular, restaurant and home chefs alike are turning to liquid nitrogen to create spheres, gels, foams, and even ice cream. While liquid nitrogen can be safely used in a range of culinary applications, there are important safety risks to be aware of when working with this substance.

The Hidden Dangers of Liquid Nitrogen in the Kitchen

Nitrogen can help chefs freeze alcohol, which doesn’t freeze under freezer temperatures. Nitrogen also creates a very rich ice cream, since it makes superfine ice crystals. By using liquid nitrogen to freeze foods, chefs can keep more flavor in the food and preserve higher amounts of the food’s nutrients.

It’s important to note that nitrogen is used only to alter the state of food. The nitrogen itself is not consumed.

While it is no wonder that nitrogen has become so popular in the kitchen, the substance can pose a health hazard.

Liquid nitrogen is extremely cold. If the substance were to spill on your clothing or get in your eyes, it could cause severe burns. Thus, many culinary workers wear an extra layer of clothing (such as an apron) to prevent nitrogen from causing skin burns. Special gloves protect the hands, and safety goggles prevent the eyes from nitrogen burns.

While many are aware of the burn danger from liquid nitrogen, there is a more insidious hazard. When liquid nitrogen meets the air, it starts to evaporate and turns into nitrogen gas. Nitrogen gas is a known oxygen displacer, so the more gas that escapes, the less oxygen the air has. Quickly, nitrogen gas can deplete the air to low enough levels of oxygen that respiratory problems and death via asphyxiation are cause for concern. While you may see the smoke or fog from liquid

nitrogen, actual nitrogen gas has no color or odor. Thus, if you miss the fog of liquid nitrogen, you may not know the atmosphere is oxygen deficient until it is too late.

The human brain requires a continual supply of oxygen to work properly. Without this steady oxygen supply, the brain begins to shut down. Confusion and mental fog occur, along with symptoms of respiratory distress, including nausea and vomiting. Due to the severity of these symptoms, an individual in an oxygen-deficient environment has little chance of rescuing themselves before dying.

How an Oxygen Monitor Protects Safety

If you plan to use liquid nitrogen, take the necessary precautions to protect skin and eyes from burns. Then take the extra step to install an oxygen deficiency monitor or oxygen monitor.

The oxygen deficiency monitor mounts on the wall in the area where nitrogen is stored and used. The device constantly checks the levels of oxygen in the air. As long as the air is safe to breathe, the monitor remains silent yet alert. If liquid nitrogen evaporates and begins displacing oxygen, the O2 monitor tracks the falling levels. Should oxygen drop such that the air is no longer safe to breathe, the O2 monitor will flash a visual and audio alert telling staff to get out of the kitchen.

The monitors are designed to alert when oxygen levels fall below the limits set by OSHA of 19.5 percent. When oxygen levels are between 19.5 and 15 percent, symptoms of oxygen deficiency begin to occur. Health hazards arise when levels fall below 6 percent. So, the monitor gives staff enough time to safely evacuate and avoid a health risk.

If you want to use nitrogen in the kitchen, while reducing the safety risks for your kitchen staff, invest in an oxygen monitor. Oxygen monitors from PureAire come with hardy zirconium oxide sensors, which require no maintenance and have a 10-year life span. They are an effective, efficient way to circumvent nitrogen’s hidden dangers. See PureAire’s line of oxygen monitors at www.pureairemonitoring.com


The Path to Safety for Pharmaceutical and Laboratories: Why O2 Deficiency Monitors May be Required?

To safeguard against gas leaks in pharmaceutical industries and laboratories, businesses are turning to oxygen deficiency monitors. Learn when, where, and why an oxygen monitor or O2 monitor may be required.

Oxygen Monitors in Medical and Pharmaceutical Settings

In the hospital setting, nitrogen gas is widely used. During surgeries, nitrogen powers equipment and preserves blood and tissues. Nitrogen gas is also used to freeze and destroy tissue.

Hospitals work with other gases, such as carbon monoxide, for lung diffusion testing and culturing. Laboratories growing cultures for analysis, testing, and research require that the tissue samples be grown under strict environmental conditions. Medical gases can control the environment to ensure that tissue samples are not contaminated by any sort of bad bacteria.

Magnetic resonance imaging machines use nitrogen gas to cool the magnet and keep the machine working properly. As such, it is critical to have an oxygen monitor in an MRI room to protect the safety of patients in the MRI machine and technicians performing the MRI. In 2000, a technician was killed and several others were injured when nitrogen escaped from the closed chamber and into the room.

Pharmaceutical facilities also rely on nitrogen gas for multiple uses. Since the gas can keeps oxygen out of an environment, it can ensure the purity of a chemical compound or preserve the longevity of a packaged medical product. Nitrogen is also kept on hand as a natural fire suppressant and purifier. Nitrogen gas generators allow pharma plants to access nitrogen gas on demand for a low cost.

How an Oxygen Deficiency Monitor Protects Workers in Laboratories, Hospitals, and Pharma

Staff and patients in hospitals, pharma, and laboratories need to stay safe. By installing an O2 monitor in any rooms where potentially harmful gases are used, employers can safeguard their workers’ and their patients’ air quality.

The wall-mounted monitors continually check the levels of oxygen in the air. As long as oxygen levels are above the minimum amount, the alarm remains silent. If a gas like nitrogen were to leak in MRI rooms or lab storage facilities, the amount of oxygen in the air would begin to drop. Once oxygen fell to the minimum safe level, the alarm would go off, warning staff of the problem. Staff could then leave the room and evacuate patients.

While these devices are important to protect public safety, they also keep the facility in compliance with the law. Hospitals, medical, and pharma facilities are required to install oxygen monitors where potentially hazardous gases are used.

Since medical and pharma settings may store and use gases in many locations, multiple oxygen monitors may be needed. PureAire’s oxygen sensors can last for 10 years with no maintenance. Our quality oxygen deficiency monitors are of the highest quality, to provide peace of mind and total protection in medical and pharmaceutical settings.

Olympic Training: Use of Cryotherapy and Hypoxic High Altitude Training

Olympic athletes have been known to try some pretty strange things to enhance their performance. Major Olympic swimming star Michael Phelps has been relying on a special device for the last year, a high-altitude sleep chamber that retails for $15,000. While therapies like high-altitude training and cryotherapy can be beneficial, they do have risks. Learn why you need an oxygen monitor for cryotherapy and high-altitude training chambers.

How High Altitude Training Benefits Athletes

A high-altitude chamber mimics the conditions of high altitude. Phelps keeps the air inside his chamber at 8,500 to 9,000 feet. High altitude environments have less oxygen than low altitude environments. As a result, your body has to work harder to breathe. For Phelps, this means that he can train his body to perform better even while getting a good night’s sleep.

The high-altitude chamber Phelps used is made by Hypoxico. Their high altitude chambers can be adjusted to a maximum level of 12,500 feet. By sleeping in a low oxygen environment and living in an oxygen-rich environment, athletes can avoid the fatigue and dehydration associated with living in a high altitude environment. Since bodies produce more red blood cells at high altitude, the sleep chamber also promotes faster muscle recovery. This is essential for training.

Michael Phelps is far from the only athlete to try this type of sleep training. It’s popular among endurance runners, who rely on breathing capacity to fuel their runs. Dwayne Wade, Lebron James, and Santonio Holmes also use the high altitude training. Pro golfer Tiger Woods reportedly relies on high altitude training too.

How Cryotherapy Benefits Athletes

In addition to sleeping at high altitudes, many top tier athletes also turn to cryotherapy. Whole body cryotherapy exposes the body to extreme temperatures of -240 Fahrenheit for a set period of time. Athletes can stop the treatment at any time using safety measures. The dry chilled air elicits a response from the circulatory system. As a result of spending a few minutes in a cryohealth chamber, athletes decrease inflammation and lactic acid. They also initiate self healing through the nervous system.

The San Antonio Spurs, Los Angeles Clippers, Los Angeles Sparks, Minnesota Timberwolves, Toronto Raptors, and TCU Horned Frogs all rely on services from Cryohealthcare. Floyd Mayweather Jr., LeBron James, and Kobe Bryant also depend on cryotherapy for their competitive edge.

Why You Need an Oxygen Monitor with High Altitude and Cryotherapy

Both high altitude sleep chambers and cryotherapy put athletes at the risk of exposure to levels of oxygen that are too low. When the air does not have enough oxygen to breathe, athletes can suffer respiratory complications and may die from asphyxiation.

High altitude chambers need an oxygen deficiency monitor to measure the levels of oxygen in the sleep chamber. If the settings on the machine malfunction, too much oxygen could be removed from the air. With just a couple of breaths of oxygen-deficient air, someone can become unconscious. Within minutes, they could die.

Cryotherapy chambers rely on nitrogen gas to keep the air chilled to -240 Fahrenheit. Nitrogen gas is known to deplete oxygen from the air. As long as the chamber has enough oxygen, nitrogen can be used to chill the air without posing a health hazard. Yet if there is too much nitrogen, the air will become oxygen-deficient. Thus, anyone taking a dip in the cryohealth chamber could become a victim of death by asphyxiation.

To safeguard users, cryohealth chambers rely on an installed oxygen monitor to continually check levels of oxygen in the air. Likewise, the sleep chamber uses an O2 monitor to track oxygen levels during use. With an O2 monitor installed, users can enjoy their form of training without worry that it will harm their health.

Hypoxico relies on PureAire’s line of oxygen deficiency monitors as a safety feature in their high altitude sleep chambers. PureAire’s O2 monitor contains a zirconium sensor, which can function properly for up to 10 years. The monitor will provide instant notification if oxygen falls below safe levels, so that athletes can escape in time.

PureAire Oxygen Analyzers & Oxygen Monitors for Nitrogen Generators or Air Separation Plant

Nitrogen has many uses in industrial applications where oxidation would be undesirable. From carbonizing beer to preserving food, reducing fire danger, and cleaning equipment, nitrogen is a safe, inexpensive gas. For companies that need a steady supply of nitrogen gas, nitrogen generators work well. Learn about the uses of nitrogen generators and why you should use oxygen monitors in environments where nitrogen gas is created.

How Nitrogen Generators Wor

Nitrogen for packaging works well in the food and beverage industry for food packaging and bottling of wine. Nitrogen also helps with metal processing, improving the end quality of the product by reducing the chance for oxidation. In the pipeline industry, nitrogen creates a high pressure environment that improves safety.

Nitrogen generators allow you to create nitrogen from compressed air. If you use nitrogen cylinders, then you know how inconvenient they can be. If your supplier is late, you risk running out of nitrogen you need to run your business.

These generators are easy to operate. All you need to do is connect a compressed air line to the inline for the nitrogen generator. Then connect the outlet to the nitrogen line. Now, the generator can run continuously, and can create nitrogen gas that has as little as 10 parts per million of O2. An oxygen analyzer can help you measure the amount of oxygen in the nitrogen gas, to ensure consistency

It is both easy and cost-effective to use the nitrogen generator in-house. Since you can create nitrogen 24/7, the generator will pay for itself quickly and free you from the dependency on suppliers.

By adding an oxygen analyzer to the nitrogen generator, you can check the level of oxygen present in the nitrogen gas at any time. Purity of the nitrogen is key to successful application. The O2 analyzer runs constantly, allowing you to take at-a-glance readings and make sure that everything is working properly.

Air separation is an alternative to purchasing a nitrogen generator. In an air separation plant, you can separate the air into its elemental components. Natural air is compressed and sieved, to remove any impurities. The compressed air is heated and cooled until the different elements reach boiling points, and separate out. The elements are then returned to a gaseous state, at which point they are ready to be used. As with nitrogen generators, air separation plants benefit from the use of an O2 analyzer to keep an eye on the levels of oxygen.

Safety Benefits of Oxygen Monitors and Analyzer

While oxygen analyzers are beneficial, they also have a practical purpose when used with an air separation plant or nitrogen generator. The oxygen analyzer helps ensure that the nitrogen gas has a very low level of oxygen. It can measure oxygen levels from 0-1000 ppm and keep the oxygen to the minimum needed for your specific usage.

An oxygen monitor can check the environment for levels of oxygen in the air. As long as there is enough oxygen in the air, then the O2 monitor is silent. Should levels of oxygen drop, the O2 monitor will sound an alarm and flash a light, alerting workers to the situation. While nitrogen generators do have a leak detection system, it's a good idea to add an oxygen monitor as a failsafe.

Nitrogen gas actually depletes the levels of oxygen in the air. If enough nitrogen gas were to leak out, it would reduce the oxygen below safe levels. As a result, workers could become unconscious, experience dizziness, or even die from asphyxiation. By having an oxygen monitor, you can ensure that there is no leak of nitrogen gas from the generator or supply lines.

PureAire offers oxygen monitors with a zirconium oxide sensor. Capable of lasting for up to 10 years with no maintenance, these O2 monitors are a reliable way to ensure that nitrogen does not pose a health hazard in your plant. When coupled with the oxygen analyzer, they allow you to product nitrogen to run your business without creating a health risk for your employees.

PureAire Oxygen Analyzer for 3D Printers: How Argon is used and Why O2 Detection is Required

Thanks to new technologies, the 3D printers that have been used to create plastic three-dimensional objects can now print metal. Titanium 3D printing is possible thanks to a technique called DMLS, or Direct Metal Laser Sintering. While the potential to use titanium 3D printing is groundbreaking for many industries, the new advances could pose a health hazard if volatile gases used in the printing process are not contained. Learn more about the role of argon in 3D printing and how an oxygen analyzer can safeguard your employing while printing.

What Happens in Direct Metal Laser Sintering?

3D printing of plastics uses an additive process in which objects are constructed layer by layer or fused together cross section by cross section. These basic techniques need rethinking for titanium 3D printing. With Direct Metal Laser Sintering, a laser follows a computer-aided design (CAD) file to melt titanium powder, rendering the object. The process is similar to sculpture, in which pieces of the raw material are carved away to create or reveal a three-dimensional object or figure.

Because titanium is such a strong metal, the resulting objects are highly durable. For something like medical devices or three-dimensional replacement joints or bones, this means that individuals can get greater use out of the replacement part. Aviation professionals greet these new developments, estimating that titanium parts can cut the weight of an airplane by as much as 1,000 pounds, saving fuel on every flight.

Since the titanium powder (Or other metal powders) used in this additive manufacturing process is created from manufacturing remnants, the materials are highly cost-effective.

What are the Risks of 3D Printing?

The 3D printer operates in an inert environment, where argon prevents any unwanted chemical reactions from taking place and maintains the purity of components. The inert environment in the 3D printing machine keeps the oxygen content low, to reduce oxidization in the manufactured part. It also reduces the fire hazard by rendering combustible dust inert. Since thermal stress is controlled and titanium powder clumping is reduced, the argon improves the consistency of the final product and reduces deformities.

While there are many benefits to using argon in the printing process, and argon is harmless when contained, it does pose a health risk should the argon escape the additive manufacturing environment.

Argon is known as an oxygen displacer. This means that when argon gas leaks into the air, it physically displaces the levels of oxygen in the air. In extreme cases, staff can asphyxiate due to the lack of oxygen in the environment.

This gas is colorless, tasteless, and odorless. Were argon to leak out of the 3D printer, staff would be unable to see or smell it. As soon as oxygen begins to deplete from the room, it cause symptoms including dizziness, shortness of breath, and confusion. Even if staff suspect that something is wrong, they may be unable to escape from the area before it is too late.

When you have a poorly ventilated manufacturing space with several 3D printers going at once, the potential for oxygen displacement by argon gas increases.

How Can an O2 Analyzer Reduce Risks?

An O2 Analyzer helps keep levels inside the 3D printing environment low, to ensure the printer works optimally. Without the analyzer, there would be no way to ensure that the ppm concentration of oxygen remained at a steady state for the duration of the printing process. The oxygen analyzer checks levels of oxygen ranging from 0 to 1,000 parts per million (ppm). 3D printers using the DMLS process need to keep the oxygen under 1% or less for product manufacturing. A 0 to 25% oxygen range detector is also available. The oxygen analyzer can make sure that the air inside the chamber meets the low levels needed. Meanwhile the air outside is safe for staff to breath. PureAire's oxygen analyzers are easy to install and easy to use. Once set up, they require no maintenance and will work as promised for a set period of time.

At PureAire, we have just developed a new oxygen analyzer that works with 3D printers. To learn more about our new oxygen analyzer, please visit www.pureairemonitoring.com or send an email to info@pureaire.net

Additive Manufacturing 3D Printers: Why an Oxygen Analyzer May be Required

For the average person, Argon gas is not a topic of daily conversation, or, for that matter, any conversation, ever. It may be surprising to learn that argon is the third most common gas in the earth’s atmosphere, though most people know little about it. The word argon itself comes from a Greek word meaning ‘inactive’ because of its lack of chemical reactions. Argon is colorless, odorless, tasteless, and non-toxic, but this doesn’t mean it is completely harmless. Because it is 38% denser than air, it can displace the oxygen in an enclosed area.

One of the most modern uses of argon gas is in selective laser melting (SLM), which is a type of 3D printing. The first process in additive manufacturing requires the printing chamber be vacuumed of all oxygen. After oxygen has been removed, argon is then backfilled or released back into chamber to reduce oxygen to 500ppm or less. The oxygen analyzer (0-1000ppm oxygen range) has a sensor inside the printing chamber, monitoring oxygen while the machine is in operation.

In this process of additive manufacturing or AM, layers of a powder are then bonded together using a powerful laser (as opposed to sinter bonding them). Argon is an inert gas, and relatively inexpensive, therefore it creates the perfect environment for this process to take place in. The use of argon here permits a tightly controlled atmosphere, allowing for an oxygen free environment. Using this amount of argon requires the use of an oxygen analyzer for control.

When using the right safety precautions, like an oxygen analyzer, argon can be very useful. It is used as a shielding gas in metal printing and direct laser sintering manufacturing (DLSM) to prevent corrosion, and can even be used to reduce oxidation.

An oxygen analyzers tests the ppm of oxygen in an enclosed area to ensure it is safe begin selective laser sintering process. If a gas like argon were to leak, it would push breathable oxygen out as it filled the room displacing any breathable air. Having no color or odor, a person in the room would be unaware of this exchange of gasses until it was too late. Also, having an oxygen monitor, like ones sold by PureAire Monitoring Systems, would alert anyone around of a gas leak in time for them to seek safety.

If you are interested in using argon gas, and require an O2 analyzer contact PureAire Monitoring Systems to learn about how easy it can be to stay safe with an oxygen monitor. Argon has an important place in our modern world, so spread the word and share the knowledge of how to use argon while practicing safety.

For a reliable oxygen analyzer, look to PureAire, a company with over 15 years of experience in the field. Learn more about PureAire's products at www.pureairemonitoring.com.


Air Separation Plants and the Use of Oxygen Monitors

Air separation plants are critical for many different industries, from clean energy to manufacturing. Nowadays, cryogenic is the most common type of distillation used to separate air into its component gases - nitrogen, oxygen, and inert gases including helium and argon. If your industry relies on air separation for product development or manufacturing, then knowing how the process works is an important part of operational safety. Learn about air separation plant operation and safety protocol to be informed.

How Air Separation Plants Work

In the cryogenic air separation process, air is chilled to the liquid stage. At this point, nitrogen and oxygen can be separated out from the inert gases in the air. Each compound can then be distilled at boiling temperature, thereby returning the liquid to a vapor state. The resulting nitrogen and oxygen gases are highly pure.

To get the air ready to be separated, plant employees first filter the air to remove particles, such as dust. Next, the air is pressurized and then filtered up to several times to remove carbon dioxide, which can freeze the distilling equipment.

Using a still and heat exchanger, workers heat and cool the gas, turning it into a highly pure liquid. The oxygen liquefies and falls to the bottom, while the highly pure nitrogen gas floats above the oxygen since it is lighter.

Once separated, the gases can be kept in gaseous state or returned to a liquid state via chilling. Many air separation plants have elaborate pipe systems, whereby the oxygen or nitrogen gas can be transported directly to production lines.

Air separation plants have many diverse uses. Pure oxygen gas is a basic component of metalwork including steel manufacturing. Nitrogen gas helps preserve edible oils from oxidizing and is used as a safeguard against combustion in shipping and cargo transit.

The cryogenic process is effective and efficient at separating air; however, it does pose some safety risks. Air is safe to breathe when nitrogen and oxygen are together in the appropriate ratio. As nitrogen and oxygen are separated two distinct hazards emerge.

Pure oxygen increases the fire danger in an environment. If not controlled, this could turn dangerous.

Pure nitrogen depletes oxygen and can cause death via asphyxiation. Since nitrogen is colorless and odorless, workers may not know if the distilled nitrogen has escaped the still and infiltrated the environment. Argon acts in a similar manner, yet is a less common hazard since it is present in trace levels in oxygen.

Without a safeguard of an oxygen monitor, staff may be exposed to toxic gases. In a worst-case scenario, staff could die.

How an Oxygen Monitor Protects Staff

Between 1992 and 2002, 80 workers died from nitrogen exposure. Workers may fall unconscious after even a single breath of oxygen deficient air. If individuals do not receive oxygen in a matter of minutes, the consequences are grave.

Educating staff about the dangers of these gases is a first step toward operational safety. Installing an oxygen or O2 monitor is the next step to keeping everyone safe.

An O2 monitor measures the levels of oxygen in the air at any given time. The device takes sample readings of the air and remains silent as long as there is sufficient oxygen in the environment. Since argon and nitrogen deplete oxygen, the level of oxygen in the room will decrease if a gas leak occurs. When oxygen levels fall below the minimum safety level, the O2 detector will sound an alarm. Trained staff will then know to evacuate the premises until emergency assistance arrives.

Oxygen deficiency monitors from PureAire are guaranteed to perform for 10 years. These oxygen deficiency monitors have a zirconium oxide sensor, which accurately measures air oxygen levels in temperatures as low as -40 Celsius. The O2 monitor from PureAire is an efficient, cost-effective way for plants using nitrogen, helium, or argon to keep staff safe from the known health hazards of these gases.

If you seek an oxygen monitor that needs no maintenance, no calibration, and is guaranteed to last, you may be interested in PureAire's line of products. Learn more at www.pureairemonitoring.com or by emailing info@pureaire.net for more information.


Chlorine Safety and Prevention: How to Protect Yourself from Chlorine Leaks

While chlorine gas is widely used in swimming pools, water treatment facilities, cleaning products, pharmaceutical products, and in many other industries, the gas is highly toxic when handled improperly. Training your workers on how to safely use chlorine is one part of health and safety best practices; monitoring your workplace for chlorine leaks is another. Learn about the hidden dangers in this common substance and how you can stay safe.

The "Hidden Dangers" of Chlorine

So many everyday things that you see and touch have come into contact with chlorine. The substance is a common cleaner and disinfectant because it is easy to use and inexpensive. Chlorine is also used in agricultural pesticides, in the manufacturing of drugs, in wastewater treatment facilities and the sanitizing of everyday drinking water, in paper manufacturing, in hospitality swimming pools and spas, and in many other products. No matter where it is being used, chlorine must be properly handled by all staff at all times.

At room temperature, high chlorine levels are toxic. If chlorine gas comes into contact with substances including ammonia, ether, hydrogen, and turpentine, it can combust. Since this gas can cause breathing problems, it is dangerous to individuals with respiratory problems including asthma.

The gas is yellowish at room temperature and has a distinct odor, so staff will be able to see and smell the substance. While this does aid in awareness of chlorine leaks, it is not sufficient to trust that your staff will see or smell leaked chlorine and leave.

Employees exposed to chlorine can experience eye damage, coughing, choking, frostbite on the skin, and respiratory problems. In a worst case scenario, staff can die from suffocation due to sustained chlorine exposure.

Fortunately, fixed gas monitors are an efficient way to protect staff from a chlorine leak.

How PureAire Universal Gas Detectors Protect You From Chlorine Leaks

At PureAire, we offer universal gas monitors that protect against chlorine and other gases. PureAire's universal gas detectors are compact and designed for wall mounting in areas where you store or work with gases. Once installed, these detectors continually performs gas detection and monitoring. The maximum acceptable level of chlorine that workers can be exposed to, per OSHA regulations, is 1.0 parts per million (ppm). Chlorine is considered to be "Immediately Dangerous to Life and Health" when levels reach 10 ppm. As long as levels of chlorine remain below the acceptable safe level of 1.0 ppm, the detector is silent. Yet if gas leaks out and levels rise above the maximum acceptable level, the PureAire gas detector will sound an alert and flash a light so that staff will see or hear the alarm.

Staff can then have enough time to stop what they are doing, exit the premises, and wait for emergency responders to contain the chlorine leak. When staff are alerted as soon as levels exceed those deemed safe, they can get out of the building before succumbing to chlorine-related health hazards.

The universal gas monitor from PureAire protects against toxic gases including chlorine, hydrogen chlorine, ammonia, hydrogen fluoride, and other gases. Once installed, the PureAire detector will last for more than seven years without requiring any maintenance. If you seek a safe solution that delivers peace of mind and effective protection from chlorine leaks, PureAire's fixed gas monitor is a cost-effective, reliable option.

Capable of chlorine gas detection in temperatures as low as -25 Fahrenheit up to to 22 Fahrenheit (-32 C to 50 C), these gas detectors offer flexible gas monitoring for visible and invisible toxins. PureAire's universal gas monitor is also water resistant and capable of detecting gases within a 30-foot range.

Since PureAire's detectors have such a long lifespan, they are a convenient way to address gas leaks in the workplace. An optional long life renewable sensor extends the lifespan of these gas monitors by recharging the battery.

After you install the gas monitor, your staff can work with chlorine and other gases with the certainty of knowing that their safety is protected. To protect your workers and your business assets, look to PureAire. View their fixed gas monitor or learn more at http://https://www.pureairemonitoring.com/.


PureAire Universal Gas Detector Offers Protection Against Toxic Levels of Ammonia

In March of 2016, an ammonia gas leak at a seafood processing plant in Boston left one worker dead. The fumes at the plant were so powerful that firefighters could not promptly enter the scene to mitigate the gas leak and try to save the staff member until much later. Reports show that 5,300 pounds of ammonia gas leaked out of the plant. If you work with ammonia at your facility, learn why this gas is so dangerous and one simple thing that you can do to prevent a tragedy like this from affecting your workers.

The Hidden Dangers of Ammonia

Ammonia is commonly used in refrigeration of dairy, meat, food processing, and cold storage. In fact, almost everything you can buy at your local grocery store has passed through an ammonia refrigeration site before making its way to your local store.

A mixture of nitrogen and hydrogen, ammonia has been used in refrigeration since the 1800's. It is energy-efficient, inexpensive, more environmentally friendly than chlorofluorocarbon (Freon) refrigerant, and widely available via commercial manufacturing. While it may have started off as a refrigerant of food, ammonia is also used today for ice and water chilling in office buildings. In Europe, ammonia has additional applications in air conditioners in public buildings including hospitals and airports. The substance is also used in industries as diverse as semiconductor manufacturing, environmental emission monitoring, agricultural fertilizer, and chemical manufacturing.

As useful as ammonia is, it is also a dangerous substance when not properly stored. It can combust at high heat. While colorless, ammonia gas has a noxious odor.

When workers are exposed to ammonia gas, they can experience skin and eye irritation. If concentrations of ammonia are high, burning and injury can result. In some cases permanent eye damage or blindness can occur.

Workers will immediately know they are exposed to a harmful substance from symptoms including respiratory and nasal burning. Even though staff have a warning due to ammonia's odor, the substance causes adaptation. Workers may perceive a slight ammonia odor at low levels of exposure, and adjust to the scent so they can't tell when concentration has surpassed acceptable levels.

In a worst case scenario, those exposed to ammonia will experience respiratory failure and die. The good news is, there are ways to protect staff from ammonia exposure using universal gas detection tools.

How PureAire Universal Gas Detectors Protect Staff from Ammonia Exposure

PureAire's universal gas monitors protect against not only ammonia, but bromine, chlorine, hydrogen chloride, hydrogen fluoride, hydrides and other gases. Once installed, the monitor continually checks levels of gases and provides a visual and aural alert if levels of any substance exceed safe levels.

This is a simple solution for round the clock gas monitoring for ammonia and many other hazardous gases. While ammonia has an odor, many other dangerous gases do not. Gas monitoring protects workers against substances they can smell as well as "silent killers" they cannot see or smell. With a universal gas monitor installed, workers can perform their duties secure in the knowledge that they will be alerted if ammonia or another substance leaks into the environment.

After installation, the universal gas detector will work for over seven years with no maintenance. PureAire's gas monitor are built to outlast the competition to provide improved peace of mind for management and staff.

If an ammonia leak were to happen, the gas monitor would sound an alarm so that workers can safely evacuate before succumbing to respiratory damage or failure. With staff outside the premises, everyone is thereby safe until first responders can deal with the leak. For example, in the Boston incident, the worker would have been able to escape the seafood plant with his life, resulting in an ammonia leak with no fatalities.

Not only is gas detection the right thing to do for peace of mind, it can safeguard your business assets and personnel from dangers. To learn more about PureAire's line of universal gas detectors, please visit http://https://www.pureairemonitoring.com/.

Fertility Clinics and Egg Freezing: Nitrogen Use and How to Remain Safe

For women who want to have children when the time is right, egg freezing is a viable option and one that has become more popular in recent years. As an abundance of fertility clinics pop up nationwide, it is important to consider the safety implications of IVF, egg freezing, and fertility clinics. Dive into the world of fertility clinics to understand how eggs remain viable -- sometimes for years after harvesting -- and what risks the environment holds.

How Do Fertility Clinics Harvest and Store Eggs?

During the monthly menstrual cycle, women release a viable egg. In the fertility harvesting process, IVF clinicians administer hormones that increase egg production so they can harvest and store multiple eggs in a one-time procedure.

Doctors first administer hormone injections to inflate egg production prior to harvesting and storage. Three days after the final injection, the eggs are ready for harvesting. At this point, female patients then have eggs harvested from their ovaries using needles. Now the patient's role is simply to leave the eggs at the IVF facility until she wishes to be inseminated.

Traditionally, eggs were frozen for long-term storage, then thawed out when patients wanted to use the eggs. This method worked, but had a suboptimal success rate during IVF.

A new method, termed vitrification, increases the success rate of egg freezing for in vitro fertilization. Vitrification uses a flash freezing process to quickly freeze the eggs for long-term storage. After the eggs have frozen, they are then stored inside tanks of liquid nitrogen until they are needed. The new method reduces the formation of ice crystals, which can damage the egg during the thawing out.

The main risk that doctors counsel patients on is the chance that some or all of the eggs will perish in the process. Freezing of eggs is still a relatively new procedure. However, there is a greater risk involved. One that could affect female patients, their eggs, and fertility clinic staff: The risk of liquid nitrogen exposure.

Nitrogen Warnings in the Fertility Clinic Setting

Liquid nitrogen is perfectly safe as long as it remains in storage tanks. If even a single tank were to develop a leak, and the substance were to spill out into the fertility clinic, a lot more would be at stake than the viability of stored eggs for in vitro fertilization.

Nitrogen has the potential to deplete oxygen from an environment. At first, this may cause discomfort, dizziness, or confusion. As the leak continues and displaces more oxygen from the room, staff can asphyxiate. Since the gas cannot be seen or smelled, employees will not know something is wrong until it is too late and lives are lost.

For the safety of clinic staff, an oxygen deficiency monitor can be installed near the liquid nitrogen tank. This monitor takes periodic readings of the oxygen levels in the room. When everything is working properly and the oxygen is within the normal range, the monitor remains silent yet vigilant. In a worst case scenario where a nitrogen leak does develop, the O2 monitor will sound an alert once the oxygen in the room falls below acceptable levels. The alarm gives staff enough notice to escape the premises before being overcome by the lack of oxygen.

Like a carbon monoxide detector, an oxygen deficiency monitor does not really do anything until something goes wrong but can save lives in the event of an emergency. As with a carbon monoxide detector, it is important to select and install a quality O2 monitor.

The latest generation of oxygen monitors from PureAire come with a zirconium sensor, which requires no calibration or maintenance. Staff can install the O2 monitor in the IVF facility and remain assured that it will work for a period of 10 years with no maintenance of any kind.

For a reliable oxygen deficiency monitor, look to PureAire, a company with over 15 years of experience in the field. Learn more about PureAire's products at www.pureairemonitoring.com.


Nitrogen Generators: Where are they Installed and How to Stay Safe?

Used in a range of industries, nitrogen generators ensure a steady supply of 99.5% pure, commercially sterile nitrogen from a compressed air storage tank. From an industrial standpoint, nitrogen generators are seen as preferable to cylinders of nitrogen as they are more reliable, more compact, and easy to use and install. However, these generators are not without risk. Learn about nitrogen generator installation best practices and how to stay safe when using these devices in your facility.

Where are Nitrogen Generators Installed?

Since nitrogen generators have such a wide array of end use cases, they wind up getting installed in different commercial environments. Nitrogen generators may exist in:

  • Brewing operations - To sparge and mix the wort
  • Food processing and packaging plants - In the food packaging process
  • Industry - To test and clean tanks and vessels
  • Engineering facilities - For use in manufacturing, testing, and product development
  • Automotive plants - In paint booths

These generators offer a steady supply of nitrogen at a lower cost than using gas cylinders. One generator takes up less room than several cylinders, saving floor space where it is needed most. A generator is easy to install and simpler for employees to use (since it requires less maintenance) than cylinders, so many manufacturers have switched from using cylinders of nitrogen to using generators.

Nitrogen generators are most often operated indoors, as these typical use cases show. In the event of a leak or other problem with the generator, escaping gas has nowhere to go other than inside the building. In some cases, the building may be set up so that nitrogen generators vent to the outside, thus offering a buffer from the harmful gas; however, it is not always possible to vent the generator to plain air.

That said, these units do post a risk. Nitrogen is a colorless, odorless gas that creates an oxygen deficient state. If the generator were to develop a leak, nitrogen gas could leak out undetected into the work environment. In a matter of minutes, nitrogen gas from a leaking tank can deplete the workspace of oxygen. To protect the health of your employees, it is necessary to only use nitrogen generators in conjunction with an oxygen monitor, which alerts staff to low levels of oxygen.

Why You Need an Oxygen Monitor With Nitrogen Generators

An O2 monitor, or oxygen monitor, continually monitors the level of oxygen in the room. When there is enough oxygen, the detector stays silent. A normal oxygen value is 21 percent by volume. If something unexpected happens -- such as a nitrogen leak -- and the amount of oxygen in the room begins to fall, the monitor sounds an alarm and flashes to grab staff attention. This way, staff have advance knowledge and can leave the work space before oxygen levels fall too low.

Oxygen monitors can alert staff if levels fall too low (19.5 percent or less) or too high (23.5 percent or above). Low levels of oxygen pose a severe health hazard for individuals, while high levels of oxygen pose a fire and combustion hazard.

Without an O2 monitor in place, staff would have no knowledge of a nitrogen problem until it was too late. When oxygen levels fall below the acceptable threshold, staff can become disoriented and fatigued, while succumbing to a euphoria that can dissuade them from noticing that something has gone wrong. Loss of coordination and mental processing skills, followed by poor judgment, vomiting, nausea, and eventually death by asphyxiation as oxygen levels continue to fall.

An additional consideration for large facilities is that nitrogen gas is often used far from the actual location of the generator. Thus, even if the generator you have purchased comes with an O2 monitor of its own, the monitor may not be able to test working conditions where the nitrogen is actually in use. A facility may need multiple oxygen monitors to make sure that all areas where nitrogen gas is used have acceptable air quality.

PureAire offers O2 monitors that work in conjunction with nitrogen generators. PureAire's line of oxygen detectors rely on zirconium sensors, which are guaranteed to work for at least 10 years without calibration. When it comes to protecting your staff, it's the wise choice.

The Hidden Dangers and Facts of Cryotherapy: How to Remain Safe and Get Health benefits too

While cryotherapy or frost therapy has been used for millennia, the new cryotherapy center fad that's become popular in salon culture has come under scrutiny when a 24-year-old woman who worked at a cryohealth center in Las Vegas was found dead after using a cryo chamber at work. Learn more about cryotherapy, what it claims to do for the body, and whether or not it can be safely used. 

The Health Benefits of Cryotherapy

Advocates claim that there are many benefits of cryotherapy and that the treatment is highly safe when it is properly performed. The type of whole body cryotherapy in use at cryohealth centers today was developed in 1978 as a rheumatoid arthritis treatment. While this treatment is often covered by health insurance in other nations, the U.S.healthcare industry does not recognize cryotherapy for insurance purposes or much regulate the field. 

Unlike immersion in an ice bath, the chill of cryotherapy is dry so it does not feel uncomfortable, like submersion in an ice bath would. Exposure to chilled air can treat sports injuries, muscle soreness, joint pain, pain and inflammation associated with health conditions like arthritis or fibromyalgia, and immune function. Some even claim that cryotherapy can help with weight loss or delay the aging process. 

Is Cryotherapy Safe? 

Individuals with certain health conditions -- including hypertension, heart disease, seizures, anemia, pregnancy, and claustrophobia -- should not use cryotherapy. For other individuals, cryotherapy has generally been considered safe. Some individuals may experience redness or skin irritation, an allergic reaction to the cold, frostbite, or skin burns. 

If the individual stays in the cryotherapy chamber longer than recommended, or the facility does not take the proper precautions, health risks increase. Typically, people are only supposed to expose themselves to the cold temperatures in the cryo chamber for two to three minutes. The salon where the woman died was apparently selling 30-minute sessions, the New York Post reports. 30 minutes is too long to spend in frigid temperatures. 

In the case of the employee who died in a cryotherapy chamber, no one apparently knew the woman was in there since she went in alone after work. Most cryotherapy chambers only allow people to use the facility when someone is onsite monitoring them as a first line safety precaution. 

Even if the employee did not follow proper procedures in entering the cryo chamber, her death raised awareness of hidden dangers in this unregulated industry. People want to know whether this popular treatment is safe for them. The salon where the woman died was not licensed with the State of Nevada. 

Safety Measures for Cryotherapy

Cryotherapy can be safe when performed by a licensed facility that has safeguards in place to make sure that those undergoing treatment do not stay in too long, do not get overlooked, and are not exposed to environmental hazards. 

One reliable way to monitor the environment of the cryo chamber is to use an oxygen monitor or oxygen deficiency monitor. An oxygen deficiency monitor continuously measures the amount of oxygen in the environment and sets off an alarm if oxygen falls below a safe level. 

Cryohealth chambers use a form of nitrogen to create a dry frost and chill the chamber. Nitrogen, when used in high doses, creates an oxygen deficient environment. In a worst-case scenario, the room could become so oxygen deficient that anyone inside could suffocate to death. 

Since nitrogen does not have an odor or a color, individuals cannot see it. When a cryohealth chamber is equipped with an oxygen monitor, the air inside will not fall below safe levels without first alerting staff to the drop in oxygen. Staff can then assist any patients in evacuating the cryotherapy chamber before something bad happens.  

PureAire offers O2 monitors that are made with zirconium sensors, which are guaranteed to last for at least 10 years and hold up equally well in humid and dry environments. Once the facility sets up O2 monitors in every cryo chamber, staff can rest assured that the monitors will alert them to any sudden change in oxygen levels with enough time to get people outside of the chamber before something bad happens. 

When a facility uses oxygen monitors inside the chambers, has a license from the State, and ensures that staff monitor the chambers during treatments, cryotherapy can be performed safely.

Additive Manufacturing 3D Printing: The Growth Progress and Need for Safety Monitors

3D printing is officially skyrocketing, with industrial applications in medical, biotech, aerospace, defense, and consumer electronics industries growing daily. At the heart of this acceleration is the additive manufacturing or AM process, which allows for easy printing from computer-aided design templates. As this new technology reaches its tipping point, review what the growth process says about the safety of 3D printing. 

3D Printing: Additive Manufacturing at a Tipping Point

No longer solely the terrain of artists and inventors making one-off products, 3D printing is finally going mainstream: Major companies including GE, Boeing, Lockheed Martin, NASA and Google have adopted 3D printing as of 2014. This widespread adoption heralds the move of 3D printing away from niche technology and toward a mainstream staple of next-generation manufacturing.

In the 3D printing process, the printer deposits layers one at a time, essentially building up the prototype before bonds the layers together. In the laser sintering process, a special laser melts and fuses the layers together, to bring the design to life. Because employees can make changes to the prototype between items, it is relatively easy to make changes to the item color, size, or shape from one printed item to the next. This makes it possible for individual medical devices or accessories to be printed from a select stock of computer-aided design (CAD) templates. 

Major companies like those mentioned above can afford to make the investment in 3D printing and AM because they have the funds to purchase the costly equipment needed for the initial foray. While 3D printers have become more widespread, they are not cheap. Compared with other types of manufacturing, it costs a lot to make something like an airplane part or a dental device using 3D printing over traditional printing. 

However, the initial expenses in 3D printing represents the peak costs to the business. After the device or the part is perfected, the company can utilize the same equipment and printing patterns to effectively mass produce the unit. Aside from ongoing expenses for printing supplies, the cost to produce subsequent parts is quite low. 

The competitive advantage of being able to offer something like a personalized medical device is well worth the initial cost of 3D printing. As printable materials continue to expand, more companies will invest in 3D printing to develop niche-appropriate custom products and solutions. This is not without its dangers to the business and its employees. Protect yourself by learning more.  

The Hidden Dangers of 3D Printing

While it may seem like a safe process -- and, indeed, the end result is quite safe -- 3D printing does utilize some potentially dangerous materials. Argon gas is particularly common in certain types of 3D printing. In the printing process, the 3D printer deposits thin layers of powder to effectively build the form that is being produced. The argon gas allows the different layers of powder to fuse together during the laser sintering, bringing the product to life in three dimensions. 

Argon is relatively inexpensive and highly effective at this task, which accounts for its widespread use in this new niche. However, argon is also a dense gas that is naturally heavier than oxygen. Were argon to escape from the 3D printing environment and enter the workshop or manufacturing floor, it would deplete the oxygen in the room. Any staff working there would thus face death by asphyxiation. Since argon is colorless and odorless, there is no easy way for staff to tell there is a problem.

As 3D printing becomes more widespread, businesses must take the appropriate safety measures to ensure a safe working environment. They must inspect printing equipment to ensure that it is functioning properly and argon will remain contained in the printer. They must also introduce safeguards to protect staff in case of a malfunction. 

One simple and cost-effective solution is to install an oxygen monitor, which is also known as an O2 monitor. This type of sensor continually monitors the levels of oxygen in the room. If oxygen levels falls below the critical safety levels, such that employee health would be threatened, the oxygen monitor sounds an alarm to alert staff to the health threat. Staff can then evacuate immediately, and appropriate measures can be taken to secure the workplace environment and protect the printing technology.

PureAire offers sophisticated O2 monitors, which use a 10+ year no calibration sensor to offer durable everyday protection. PureAire's sensors are the perfect choice for 3D printing environment protection. To learn more about PureAire's lineup of oxygen monitor for argon gas detection, please visit http://www.pureaire.net or email us at info@pureaire.net.

CO2 Monitor For Breweries: Carbon Dioxide Safety and How to Stay Safe

Carbon dioxide is a necessary byproduct of the brewing process, yet too much CO2 can be dangerous to employee health. In Germany, two workers died at the same brewery in 2012 due to hazardous levels of CO2 present in beer mixing and pressure tanks. Learn more about how CO2 levels can get out of control during the beer brewing process and ways to protect your staff from this deadly gas. 

Carbon Dioxide in Brewing

As beer ferments in stainless steel fermentation tanks, the yeast that was pitched into the wort eats up the natural sugars (glucose) over the course of 14 days or more. Lagers have a longer fermentation period of up to 6 weeks. During this time, the beer is held in a pressurized tank and kept at a constant temperature. As the yeast consumes the sugars, it creates carbon dioxide gas and ethyl alcohol. The alcohol-free wort then becomes both carbonated and alcoholic, essentially turning into beer as we know it. 

Some carbon dioxide gas escapes the fermenter through an airlock during the initial fermentation period. However, as the beer finishes fermentation and reaches its final specific gravity (a measure of alcohol by volume), the airlock is capped and CO2 is then allowed to build up inside the tank. This ensures that beer becomes carbonated and develops the fizzy mouth feel you've come to associate with beer. Additional carbon dioxide can be added to the beer as needed to control the end result and ensure consistency in commercial brewing. 

Hazards of Carbon Dioxide

While carbon dioxide is crucial to the taste and feel of beer, it is also highly dangerous. CO2 displaces oxygen, which can lead to asphyxiation if the oxygen deficiency is not corrected. CO2 can also be highly toxic, even at levels as low as 0.5%. Exposure to more than 10% by volume of carbon dioxide can cause death within minutes. By the time a fellow staff member realizes that a colleague is non-responsive or has been overcome by exposure, the damage is done. 

Brewers must control their exposure to CO2 through all aspects of the beer brewing process, from fermentation to packaging and bottling. CO2 is heavier than air, so it will settle to the bottom of fermentation tanks. The gas can then escape from fermentation tanks and hide on the brewery floor, in invisible and dangerous pockets of air. 

Since carbon dioxide gas is odorless and colorless, brewery workers may not know when they are being exposed to dangerous levels of CO2 until it's too late. Even if staff are trained in the best practices regarding carbon dioxide in the environment, they cannot protect themselves from something they cannot see or smell. 

To keep staff safe, it's a smart idea to monitor levels of carbon dioxide in the air. A dual-use oxygen/carbon dioxide sensor can monitor existing levels of CO2 and alert staff if the amount of CO2 start to rise. This monitor can also track the level of oxygen, sounding an alarm if oxygen levels fall to a point where staff do not have enough oxygen to breathe.

When levels of CO2 reach the point that can be hazardous to health or exceed the minimum exposure risk, or when the amount of oxygen in the air becomes too low, visual and auditory alarms go of that alert all staff on the brewery floor to the dangers. Staff can then evacuate the premises safely.  These monitors take readings of the levels of O2 and CO2 in the environment at all times. If levels become too high, brewery staff can remove carbon dioxide from the environment by using the ring main or manually removing the CO2. 

PureAire offers a dual O2/CO2 monitor that has a zirconium sensor, which is uniquely equipped to perform in humid environments where temperatures fluctuate. The same Co2 detector can last for up to 10 years, and will not require significant maintenance or calibration to remain accurate. Compared to other brewery CO2 monitor offerings, PureAire's are accurate, durable, reliable, and easy to use.  As a leading expert in the area of carbon dioxide monitoring, PureAire has more than 15 years of experience creating durable oxygen deficiency monitors.

Ice Cream Freezing Using Nitrogen: How to Stay Safe while using Nitrogen

Liquid nitrogen is a powerful and potentially dangerous form of nitrogen that freezes the water content of food and beverages within seconds. Ice cream manufacturers have developed new efficiencies in the ice cream freezing process by adopting liquid nitrogen to improve the workflow and quality of the finished product. Unfortunately, liquid nitrogen can actually be dangerous if it is not handled properly. If some of the nitrogen remains in the product either as a gas or as a liquid, it can cause serious internal damage.

The risks of working with liquid nitrogen

In addition to its popularity in the ice cream manufacturing business, liquid nitrogen has become a popular tool in high-end restaurants and bars. Chefs and bartenders use the substance to flash-freeze items and create a unique display of fog as the liquid nitrogen is exposed to air. When everything works properly, the liquid nitrogen is not a hazard. However, the substance can cause significant harm if it is not properly handled in the kitchen, or if some of the liquid nitrogen escapes into the atmosphere and turns to gas. As the BBC reported, a British teen had to have her stomach removed after she drank a cocktail that contained liquid nitrogen, and a lab worker died of asphyxiation after a liquid nitrogen spill in the lab.

Liquid nitrogen is colorless, tasteless and odorless. It is also extremely cold, with a temperature of -321 degrees Fahrenheit. If your workers accidentally get liquid nitrogen on their skin while manufacturing ice cream, they will suffer severe burns. If some amount of the nitrogen remains in the finished product, and customers actually eat the ice cream, it can cause esophageal and stomach tissue to freeze. This is extremely painful and highly dangerous.

Controlling liquid nitrogen in the manufacturing process

Now that we've explained some of the risks of liquid nitrogen, we hope you are aware of the significant danger that it can pose to your staff and your reputation in the marketplace. Luckily, there are safeguards in the process that can make sure your staff are not unduly exposed to liquid nitrogen, spills are noted before they can cause damage, and no trace of liquid nitrogen remains in the final product.

When nitrogen becomes loose in the atmosphere, it creates a state of oxygen deficiency. When there is not enough oxygen in the room, workers will not be able to comfortably breathe. If this continues, there will eventually not be enough oxygen for your workers and death by suffocation can occur. Since liquid nitrogen has no odor or color, workers may not notice its presence until it is too late.

That's where an oxygen sensor comes in. An oxygen sensor or O2 deficiency monitor is able to track the oxygen levels in the manufacturing plant at all times, even when temperatures fluctuate. The O2 deficiency monitor takes regular readings of the oxygen in the environment and notices if the oxygen level drops in the building. The sensor then notifies employees that there is a problem, giving staff enough time to evacuate the premises before anything bad can happen.

Oxygen deficiency monitors from PureAire use zirconium sensors. These perform well regardless of environment humidity and are guaranteed to last for 10 years or more. Compared to other types of O2 sensors, which are not able to last as long and require maintenance and calibration to continue to work, PureAire's sensors offer the unbeatable combination of reliability and performance.

A leading expert in oxygen deficiency monitoring, PureAire brings over 15 years of experience to bear in creating the industry's best oxygen deficiency monitors. Learn more about the PureAire Oxygen detector visiting the business website, www.pureairemonitoring.com.

PureAire O2 Monitor for Food Manufacturing Tunnel/Freezers with N2 and CO2: Using a 10 Year No Calibration Sensor

For flash freezing nothing beats a liquid nitrogen or carbon dioxide immersion or tunnel style freezer for efficiency, overall performance, and cost savings. If you haven't yet switched to an immersion freezer, doing so now could position you to better compete in your market segment and save money over time. Learn more about why these freezers are a must for frozen food manufacturers.

Immersion Freezers: How They Work

Ideal for freezing seafood, poultry, meat, and marinated or glazed products, these freezers use a conveyor belt to ferry food items through a liquid nitrogen or carbon dioxide bath. When the food is fully immersed in the gas, which is held at a steady temperature suitable for freezing food items, it freezes completely in seconds. This locks in nutrients, flavor, and texture to preserve the best qualities of the item.

Unit controls accommodate for fluctuations in the product load and variations in temperature of the incoming food items to enforce quality control every time. A turn up/turn down capability allows you to save money by moderating unit performance; the unique space-saving design and tunnel orientation reduces air infiltration and helps maintain best practices in unit sanitation.

By offering a better yield retention, a low capital investment, and lower operating costs, these units allow you to increase your production rates without increasing your staffing or your physical footprint. The immersion freezing system is customizable for a wide range of products and ensures the consistent quality in frozen foods you need.

These freezers run on inert gases, which deplete oxygen from the air. To protect workers and maintain safety, you must ensure that your freezer has an O2 monitoring system, which ensures that there is enough oxygen in the environment and alerts staff if the level of oxygen falls below the minimum safe level.

Why You Need an Oxygen Monitor For Your Immersion Freezer

If oxygen levels in the work environment get too low, staff working in the area may not have enough oxygen to breathe and could asphyxiate. PureAire's O2 monitors are capable of performing in sub-zero environments, where other oxygen sensors may fail to perform consistently.

The oxygen monitor keeps tabs on the amount of oxygen in the environment at all times. Even in a sensitive environment like the tunnel or immersion freezer, where the temperatures are constantly changing as food cycles off of and on to the conveyor belts, the oxygen monitor is able to provide a stable reading to ensure accuracy and protect your employees.

This oxygen deficiency monitor features a zirconium sensor, which is able to detect oxygen levels across the temperature spectrum and regardless of humidity. The oxygen monitor is guaranteed to perform accurately for a period of 10 years or more, without requiring the time-consuming maintenance that another oxygen detector might need. Additionally, you will not need to calibrate the oxygen monitor, as you would with other models. This offers an improvement over disposable sensors, which increase your bottom line and the amount of waste you produce.

When you switch to a tunnel or immersion freezer, you stand to boost your production capacity and your bottom line. Oxygen detectors from PureAire can help you save as much as $475 per year off our operating expenses while supporting your overall business growth.

With over 15 years of experience, PureAire is the industry's leading expert in oxygen monitoring. To learn more about the PureAire Oxygen Monitoring System, visit the company's website at www.pureairemonitoring.com or email info@pureaire.net.


Argon Gas, 3D Printing, and How to Stay Safe

For the average person, Argon gas is not a topic of daily conversation, or, for that matter, any conversation, ever. It may be surprising to learn that argon is the third most common gas in the earth’s atmosphere, though most people know little about it. The word argon itself comes from a Greek word meaning ‘inactive’ because of its lack of chemical reactions. Argon is colorless, odorless, tasteless, and non-toxic, but this doesn’t mean it is completely harmless. Because it is 38% denser than air, it can displace the oxygen in an enclosed area, asphyxiating anyone inside.

When using the right safety precautions, like an oxygen deficiency monitor, argon can be very useful. It is used as a shielding gas in metal work and welding to prevent burning, and can even be used to extinguish fires. As a preservative, argon can be used to displace oxygen out of packaging to extend shelf life by preventing oxidation and spoilage. Even light bulbs are filled with argon to prevent oxidation of the filament.

One of the most modern uses of argon gas is in selective laser melting, which is a type of 3D printing. In this process of additive manufacturing, layers of a powder are bonded together using a powerful laser (as opposed to sinter bonding them). Argon is an inert gas, and relatively inexpensive, therefore it creates the perfect environment for this process to take place in. The use of argon here permits a tightly controlled atmosphere, allowing for an oxygen free environment. Using this amount of argon requires the use of an oxygen monitor for safety.

An oxygen deficiency monitor tests the percentage of oxygen in an enclosed area to ensure it is safe to breathe. If a gas like argon were to leak, it would push breathable oxygen out as it filled the room displacing any breathable air. Having no color or odor, a person in the room would be unaware of this exchange of gasses until it was too late. Having an oxygen monitor, like ones sold by PureAire Monitoring Systems, would alert anyone around of a gas leak in time for them to seek safety.

Looking Hot while Staying Cool: Liquid Nitrogen at the Club

You feel the pulse of the music and the energy of the crowd around you. The beat is infectious and before you know it you are on the dance floor moving your body and having a good time. As the rhythm builds and your hips shake, one thing is holding you back and preventing you from fully enjoying the night. You are just too hot. You left your house looking like a million bucks and now you are a sweaty mess who is one song away from completely melting.

Seconds before you make the decision to escape the crowd and mop up your dripping face, a blast of cold air seemingly from the heavens sweeps across the club and sends a chill through your overheated body. You breathe in deeply and feel refreshed and alive, as you change your mind and stick it out to dance a while longer. You are happy just where you are, looking hot but feeling cool.

The cold blast you felt didn’t come from the heavens, but from a specifically designed and constructed cryogenic system created for the club. A quick blast of liquid nitrogen is all it takes to cool the crowd and have you feeling renewed. This liquid quickly dissipates into a gas, and, because it is denser therefore heavier than air, falls onto the dance floor and the sweaty people below.

Nitrogen is odorless, colorless, and tasteless, making it ideal for going unnoticed (other than a nice cool feeling). These qualities are also what can make it dangerous, because a room could fill with nitrogen without anybody noticing before it is too late. If the right safety precautions, like an oxygen deficiency monitor, are in place, you can party on in confidence. These monitors, like the ones sold by PureAire Monitoring Systems, make sure the oxygen level in the room is at a safe and breathable level, which changes as it is displaced with a heavier gas like nitrogen. If this occurs, an alarm will sound and you will be evacuated before anyone is harmed.

If you are looking for a cool a new experience, try attending a club with a liquid nitrogen system, but always remember, safety first. Check with the club and make sure they are using an oxygen monitor, and if they are not, have them contact PureAire Monitoring Systems to get hooked up.


Long Lasting Safety with PureAire Monitoring Systems’ 10+ year sensors

When it comes to oxygen deficiency monitors, PureAire makes the longest lasting units on the market.  They believe your safety should not be taken lightly, and have created a reliable and affordable monitor that will outlast all of their competitors. PureAire Monitoring Systems has broken away from the norm of using disposable sensor cells, and has introduced the groundbreaking technology of a 10+ year maintenance free sensor.

Disposable sensor cells have been an international standard in oxygen monitors for decades, but they are far from ideal.  They require frequent maintenance and monthly to quarterly calibration, which can be costly.  Without calibration, false alarms will occur, or worse, a failure to alarm in the event of oxygen deficiency. The reliability of these disposable sensors can even be affected by changes in barometric pressure.

PureAire Monitoring Systems has come up with a unique product to solve these problems.  Their oxygen deficiency monitors include a Zirconium Oxide sensor, which lasts for 10+ years.  This sensor is not affected by barometric pressure, and never needs to be recalibrated. This means that it will continue working without flaw toward keeping you safe over many years.

With over 4,000 units in the field, PureAire’s oxygen deficiency monitors continue to gain popularity and support amongst its users.  No maintenance means no hassle, and more time to focus on your work while continuing to stay safe.

Cryotherapy is Cool

Cryotherapy is a real facet of medical treatment that uses extremely low temperatures to help with pain and inflammation.  Not to be confused with cryopreservation, in cryotherapy the patients are only subjected to the cold for minutes. It seems like something futuristic, but it is actually an increasingly common treatment among athletes to replace ice baths and ice pack therapies. 

More specifically, cryogenic chamber therapy, or Whole Body Cryotherapy (WBC), uses liquid nitrogen to cool a chamber to around -185oF.  The patient spends a few minutes in the chamber wearing only a bathing suit, socks, gloves and facial protection (to prevent frostbite), allowing the skin temperature to drop while the core body temperature remains stable.  This WBC treatment improves many types of muscle and joint pain and helps in the rehabilitation of injuries. 

These cryotherapy systems are currently being used by sports teams such as the San Antonio Spurs, the LA Clippers, and the Minnesota Timberwolves, just to name a few. Everyone from Olympians, to rugby players, to non-athletes looking for pain relief utilize WBC. The super cooling power of liquid nitrogen can be a blessing to those in pain, but precautions need to be taken to assure this tricky chemical remains safe.  In the event of a liquid nitrogen leak, the patient could suffocate from lack of breathable air.  This is why an Oxygen Deficiency Monitor is important to have in any facility that uses liquid nitrogen. 

PureAire Monitoring Systems provides a product that would be ideal for this type of application.  Their Oxygen Deficiency Monitor that uses a sample draw system is one of the best in the industry, and can be hooked into an alarm or horn and strobe to alert the chamber operator and patients in case of a leak.  The oxygen monitor can even be programmed to turn off the nitrogen tanks in the event of a leak in the system.

The O2 monitor would be situated outside the chamber. Through a tube, air samples from inside the chamber would be analyzed to make sure the oxygen level remains at a safe and breathable 20.9%.  Any nitrogen leak would reduce the percent of oxygen and trigger an alarm.  Because the oxygen deficiency monitor’s sensor lasts at least 10 years without maintenance, safety is guaranteed for many years to come.  Cryogenic chamber therapy has the potential to help many people treat their pain, and with the use of an oxygen monitor, they can do so safely.

Liquid Nitrogen in Human Oocyte Cryopreservation

The word cryopreservation sounds like something from a science fiction movie. Maybe a man from the past was frozen in time, only to reawaken decades later, unharmed and unaware that he had been frozen at all.  Though this scenario seems far-fetched, on a smaller scale, cryopreservation is a commonplace practice in the 21st century.  While a grown man cannot be frozen and awoken, the building blocks of man are fair game. 

Human oocyte cryopreservation, or egg freezing, is a way to freeze and preserve a woman’s eggs. At a later time, these eggs can be thawed and fertilized and used to impregnate the woman. There are many reasons a woman may be a candidate for this procedure.  Some of these reasons are age, early menopause, and pre chemotherapy or radiation therapy, which may damage eggs left in the body.  In any case, if a woman learns that she will be unable to produce healthy, viable eggs in her future, oocyte cryopreservation is a good option to ensure she has healthy eggs if she decides to try conceiving at a future time. 

Semen and embryos can also be treated and cryopreserved in a similar way.  These specimens can remain frozen for a long period of time.  Embryos can be stored for up to 16 years, and semen as long as 22 years.  This allows someone who is going through an illness or separation from a spouse to wait until a more viable time for implantation for conception.

Most people can easily understand the concept of freezing something to save for later, but the frozen eggs are not stored in your average icebox.  Instead, liquid nitrogen freezes the eggs at −321 Fareignheight. This temperature is considered a deep freeze. With the addition of a cryoprotectant to deter ice crystals from forming, the specimens remain in the deep freeze until they are thawed for later use.  Amazingly, over 500,000 live human births have been a result of such technologies. 

There are over 400 facilities nationwide that can provide the oocyte cryopreservation procedure to women in need.  On the patients end, the facilities seem like ordinary doctors offices, but the real magic takes place behind closed doors.  The scientists and lab technicians use liquid nitrogen to conduct the deep-freezing, which can be very toxic if not used correctly.  They rely on oxygen deficiency monitors to detect any lower than average levels of oxygen in the vicinity, which may indicate a nitrogen leak.  For the whole sequence to go off without a hitch, the scientists need to remain confident in their safety throughout the process.

Pureaire Oxygen Monitoring Systems has created the perfect product to ensure such safety.  Their O2 monitor is the best in the industry.  The zirconium oxide sensor in the monitor lasts 10+ years with no maintenance or recalibration, making the product last longer than any other. This makes the monitor very cost effective, as it does not require additional purchases on a yearly basis.  Also, the monitor’s ability to link to an alarm system, horn and strobe, and exhaust fan help warn people across a facility to evacuate an unsafe area. 

There is no question that today’s scientific technologies are impressive, yet ever evolving.  As a company, Pureaire Oxygen Monitoring Systems vows to support these growing technologies by keeping researchers safe and giving them the confidence to do their job creating families of the future.

Helium and MRI Rooms Around the World

Helium gas is something most people feel fairly familiar with.  Children are enthralled with the magical beauty of a floating balloon, watching it reach toward the sky and hoping not to lose their grip on the string.  Helium feels safe, and while people surround themselves with flying wonders filled with this lightweight gas, the real magic of helium is taking place in MRI rooms across the globe.  With this magic, though, comes some danger. 

Magnetic Resonance Imaging (MRI) uses strong magnetic fields to surround the part of the body needing to be studied.  The resulting images are important for diagnosis and further understanding of a problem, but it is equally important that the procedure be safe and controlled.  In the process of using the MRI machine, the magnet becomes superheated, and this heat needs to be kept in check.  Liquid helium, at a temperature of  -450° F, surrounds the magnet and keeps it cool enough to remedy the danger of overheating, in turn posing its own risk. 

A Helium leak would displace the oxygen in a room, suffocating anyone inside.  Because it is colorless and odorless, an oxygen deficiency monitor is required for detection.  A person closed inside the room would not notice the leak on their own, and it would be too late.  In the event of a helium leak, an O2 monitor would sound at the first detection of oxygen displacement, warning anyone inside the room of the danger and allowing them to evacuate in plenty of time. 

Since the 1980’s, the number of MRI machines in use has risen from 12 to over 25,000.   This in turn makes MRI machines the #1 users of liquid helium in the world.  The relationship between the hot magnets and the cold helium is what makes the work of this important machine possible.  With the use of an oxygen deficiency monitor, doctors and patients at least have one less thing to worry about.  They can focus on the physical ailment at hand, and feel safe in knowing that in the event of a helium leak, they will be warned well before the point of suffocation.  

Oxygen Deficiency monitors are recommended in all MRI facilities, and are REQUIRED in all New York City MRI rooms.  PureAire Monitoring System’s oxygen monitors are a trusted product amongst MRI designers and users, thanks to their 10 + year oxygen sensor.  Unlike the competitors, PureAire’s sensors do not require maintenance or replacement parts and are not impacted by environmental drift.  This means no false alarms or failures due to depleted sensors. Without having a yearly service call on the monitor, the cost is very efficient.  This translates to prolonged safety without maintenance, and the safest and most reliable possible monitor for this application.

“Thanks again for your support. The oxygen monitors are in their respective locations and are functioning as designed. Nice unit! Everyone thinks they are a great product. The software menu is easy to use and could not be easier to operate.” - Dominion Nuclear

“The O2 monitors are working well and doing a great job!  Alarm relays are configured with the exhaust fan and is triggered a couple of times a day if we have cryogenic bottles in the area.  Excellent product, repeatable, and reliable as advertised.”  - Gulfstream Aerospace

PureAire Releases Universal Toxic Gas Monitor

PureAire Monitoring Systems manufactures and distributes toxic gas monitors for safety, and as of August 2013, releases new toxic gas monitor called the Universal Toxic Gas Monitor.  Their monitors make sure areas where toxic gases exist the area remains at a safe and breathable level, some gasses included are chlorine, bromine, HCL, HF, ammonia, toxics, and hydrides. These gases, commonly known as toxic gases, can be hazardous or even deadly if used without the proper safety precautions.  Typical areas where these gases are used include laboratories, pharmaceutical manufacturing plants, cryopreservation facilities, semiconductors, and cold food storage. The addition this product line insures PureAire’s products are the premium choice for your safety. 

Since their beginnings in 1997, PureAire has sold many thousands of toxic gas monitors to customers including (Northwestern University, Exxon Mobil, and NASA) and laboratories (Intel, Los Alamos National Labs, USDA).  A release of toxic gases in a confined space can cause irritation, permanent damage, and even hospitalization making it direly important that every space with human occupancy be monitored. Though these gases can be highly dangerous, their universal gas monitors allow groundbreaking research to be done with the ease of knowing any leak will be immediately detected.

PureAire Monitoring Systems provide the #1 universal toxic gas monitor in the industry. With a renewable sensor lasting 7+ years, no competitor can offer the same longevity or reliability. The universal gas monitor has a built in audible alarm, 2 user-selectable relays for signals to external fans/horns/strobes, and a 4-20 mA signal. 

The introduction of the universal gas monitor provides a newer easier solution for the customer. Still used is the STX-PA Smart Gas Transmitter, though PureAire is predicting the universal gas monitor will take the STX-PA’s place. Manufactured in the USA, there is no question they are the unparalleled company to go to for your toxic gas monitor safety needs. 

The STX-PA has been sold since PureAire started in 1997 along with there 4-20mA version Aircheck Lite, also trying to be replaced by the universal toxic monitor. As with most technology, a newer updated version of a product is necessary. While the universal monitor has many of the same functions as the STX-PA this product offers more. Integrated is software enabling the customer to change the sensors by a simple plug and play. If the customer has testing which requires using HF for a few days but needs to switch to chlorine for another experiment, he/she can simply unplug the HF sensor and replace with chlorine in matter of seconds. The STX-PA would also have capabilities of switching sensors, though sending in the monitor PureAire had to take place in order to switch.

In addition to many more features listed for the universal monitor, now there is a considerable louder 90 dB audible alarm. Lastly, pricing is much more competitive starting at $1,390 for a complete system compared to a starting price of $1,990.

Best Oxygen Monitors for the New Millennium

Oxygen monitors have become a required piece of safety equipment for many industrial and laboratory environments, where the release of certain toxics can create an area unsafe for living beings (human or animal).  When making a purchasing decision on any oxygen detection monitor, one need look no further than the sensor cell found at the heart of the monitor.  While each oxygen deficiency monitor manufacturer will have their on design of the enclosure, along with the display and alarm, it’s the sensor that drives the performance and value of the device. 

Enter PureAire Monitoring Systems, with the best oxygen monitor.  Focus on delivering a more accurate solution at a lower cost of ownership became a driving force for Founder and President, Al Carrino.  “The consumer deserves a device that ensures a safe environment at a low cost of ownership.  I’m not interested in selling replacement sensor cells; I’m interested in building referenceable, happy, and loyal customers, “ says Carrino.

PureAire found the solution in a Zirconium Oxide (ZrO2) sensor, which is designed to last 10+ years with no maintenance.  Further, it operates without any environmental drift and is accurate in environments as low as –40º C.  The ZrO2 sensor does not rely on partial pressure, or need a reference gas, common to the disposable EC sensor.  Also contributing to its lower cost of ownership, unlike EC cells, no electrolyte is required to power the monitor, as all electricity is provided by its 24VDC power source.

In the world of Oxygen (O2) deficiency monitors, there has been little differentiation between manufacturers over the last three decades.  The standard has been a disposable electrochemical (EC) sensor, which delivered industry acceptable performance at an economical price.  The value was reduced however, due to the need for required frequent maintenance, including monthly and quarterly calibration.  This is due to changes in the performance of the cell as it depletes over time and use.  Without maintenance, inaccurate readings occur, resulting in false alarms, or worse, no alarm.  Other issues include inaccuracies due to the environment.  EC sensors are subject to environmental drift with barometric pressure changes, and can fail if put in extreme cold temperatures (a common need for an oxygen deficiency monitor is in freezers).  The cost of ownership is further impacted by the need to purchase a replacement cell, when calibration to acceptable standards is no longer possible.

Other features of the PureAire Oxygen Deficiency Monitor is the ability to be linked to any distributed control system or programmable logic controller, and can be placed in a NEMA 4X enclosure for all environmental conditions. Optional user-adjustable alarm relays and audible alarms are available.

Combining the superior performance of the ZrO2 and PureAire’s proprietary technology has changed the playing field, with the consumer coming out the winner.

PureAire Oxygen (O2) Monitor Used in MRI Rooms Around The World


In the early 1980’s, there were 12 Magnetic Resonance Imaging (MRI) machines in use.  Today, there are approximately 25,000 around the globe.  One item in common is their use of Helium.  Liquid Helium is most often associated with party balloons and funny voices, but 20% of the world supply of this super-cooled gas is used in MRI equipment.  Liquid helium is extremely cold (-450° F), which is necessary to cool the magnets and get optimum performance from the $3M piece of equipment.

One problem with using the gas is that it displaces oxygen, and without oxygen, people and animals suffocate.  Look no further than the relatively recent death of a young party-goer who inhaled the gas to make her voice squeaky.  Her oxygen levels dropped to a deadly rate.

Helium is a nontoxic, odorless, colorless, nonflammable gas stored in cylinders at high pressure. It can cause rapid suffocation when concentrations are sufficient to reduce oxygen levels below 19.5%. It is lighter than air and may collect in high points or along ceilings. Self-Contained Breathing Apparatus (SCBA) may be required by rescue workers.1

If a helium leak occurred in a MRI room, asphyxiation can occur, creating a dangerous environment for both facility workers and patients.  For that reason, Oxygen Deficiency monitors are recommended in MRI facilities.  PureAire Monitoring Systems Oxygen Monitors are becoming the newest safety product amongst MRI users, thanks to its 10 + year sensor.  Unlike its competitors, PureAire’s sensors do not require maintenance or replacement parts and are not impacted by environmental drift.  This means no false alarms or failures due to depleted sensors.  Further, the “set it and forget it” nature of the solution translates to the lowest cost of ownership in the industry. 

The PureAire Oxygen Monitor has been used around the world for the last 14 years.  The high reliability, low cost and PureAire’s commitment to customer satisfaction make it a customer favorite.

Are you using the right monitor for CO2?

Carbon dioxide, (CO2) detectors are commonly used to protect workers from leaks in fast food establishments and restaurants.  The OSHA, ACGIH and NIOSH CO2 threshold limit value for 8 hours, (TLV) is 5,000 PPM, and the ACGIH and NIOSH short-term exposure level, (STEL) is 30,000 PPM.  Although these agencies established worker exposure levels, they also all state:
"The health effects of Carbon dioxide is a simple asphyxiant (HE17)." 1

Workers have been seriously injured due to exposure to oxygen deficiency in fast food facilities due to faulty or non-responsive CO2 monitors.

It is fact that a carbon dioxide leak from a faulty beverage dispensing system in a work environment displaces oxygen. The real health hazard is not from exposure to CO2, it's from a lack of oxygen.   "Carbon dioxide gas is an asphyxiant with effects due to lack of oxygen." 2

"Inhaling large concentrations causes rapid circulatory insufficiency leading to coma and death. Asphyxiation is likely to occur before the effects of carbon dioxide overexposure." 3 

Virtually every publication and article written about CO2 exposure indicate that the real risk to life and health is from a lack of oxygen.  CO2 monitors can not detect oxygen deficiency so why do fast food establishments and restaurants rely on them for protecting their workers when the real risks are from a lack of oxygen?

PureAire manufactures an Oxygen monitor designed to instantly detect the smallest changes in oxygen levels as a result of a CO2 leak. The earth is a wonderful source of calibrated oxygen and unlike CO2 monitors that read 0% even when the oxygen level is lower, PureAire reads continuously monitors the actual oxygen level 24-7.  It's designed to instantly alarm to hazardous levels caused by a CO2 leak. 

PureAire’s oxygen monitor uses a 10+ year no maintenance no calibration sensor.  All monitoring system functions are 100% supervised and fault protected.  Workers are always assured of continuous protection from oxygen deficient environments from leaking CO2 and alerted in the event of a failure.  In addition the oxygen monitor has built-in alarm relays for controlling automated ventilation fans or connecting to standard fire alarm panels. 

It’s proven that a CO2 leak causes asphyxiation well before the effects of overexposure, and CO2 monitors can not be used to detect lower oxygen levels, then it's clear that companies are using the wrong monitor!

A major producer of CO2 gas actually uses PureAire oxygen monitors in their gas processing plants because of their concern of lower oxygen levels due to CO2 releases.  We agree with them.

Is your company using Nitrogen or other Cryogenic gases? Why PureAire Recommends an O2 Deficiency Monitor for Safety.

PureAire Monitoring Systems, Inc. focuses solely on safety in the workplace, and in laboratory environments. Oxygen deficiency monitors are used in areas using Nitrogen, Helium, Argon, and Carbon Dioxide. PureAire strongly recommends an oxygen deficiency monitor to be installed anywhere cryogenic gases are being stored.

The purpose of an oxygen monitor is to alert employees in the immediate area if there is a spill of nitrogen with audible alarm. The use of an O2 monitor creates a safer environment for employees and can alert local fire panels in a building as well. In New York, NY any area using more than 50 gallons of nitrogen the law states, it is mandatory for an oxygen monitor to be installed.

The largest problem with these specialty gases are, if a spill occurs there is no noticeable scent or effects. A nitrogen spill can create an oxygen deficient environment rapidly within seconds. For the time it takes the body to realize there is zero breathable oxygen, it is too late. A person will pass out from oxygen deprivation immediately. This is one of the most preventable incidents; simply install an oxygen deficiency monitor for safety.

Consider an argument for medicine. If one was to travel to the Amazon in South America, where malaria is common, being unaccustomed to the jungle, wouldn't it be wise to take malaria pills? What if you have a family history of diabetes? As a family member you may consider taking any necessary precautions to possibly eliminate the concern of diabetes. Maybe by being more physically active, or having a healthier diet, this may delay or stop the onset of diabetes.

An oxygen monitor is also similar to a Fire detector in your home or office. You never expect to have a fire, but a fire detector is installed for safety as a precaution.

PureAire feels the oxygen monitor is the preventative medicine. Scientists and researchers will always continue to use nitrogen for their experiments. Doctors will continue to use helium to cool the large magnets used for images in the MRI scanner. Carbon dioxide will still be used for all beverage dispensing systems at fast food chains. The one factor people cannot eliminate is the use of cryogenic gases used in everyday life. The only known safety, and scientifically proven device is the oxygen deficiency monitor.

The rooms dimensions, a size of the cylinders, the quantity of the cylinders, the types of cryogenic gas being used, whether the gas is being piped into a room, and  height of the ceiling all play a role on where, and how many monitors are required. PureAire often gets the question, where do we place the oxygen monitor? How many O2 monitors should we use?

A few simple tips can help save a life. Helium is lighter than air, so it is recommended to mount the monitor closer to the ceiling, whereas nitrogen/argon is heavier than air, so mounting the monitor closer to the ground would make sense. Carbon dioxide is also heavier than air settling to the ground.

PureAire manufactures oxygen deficiency monitors for many different areas. In all cases PureAire use an oxygen deficiency monitor using a 10+ year sensor. PureAire can be contacted at 1-888-788-8050, http://www.MonitorOxygen.com, and http://www.PureAireMonitoring.com.

They are continuing to push the envelope of technology with the help of well esteemed engineers, and president.

One monitor that has helped attribute to PureAire’s sales is their Oxygen Monitor. Known as the Aircheck TX-1100-DRA, this monitor uses a 10+ year sensor technology which has left their competitors in the dust. Being sold since the 1970’s by their affiliate company Bionics, PureAire re-engineered the monitor and complimented the sensor technology, ultimately increasing the accuracy and stability. The newly developed 3.05 revision software update has even outperformed their previous tests. In addition to their newly designed software, there is a built in horn/strobe, LCD backlight digital display, 2 user selectable alarms, and a 4-20 mA signal for control panels. There hassle free Oxygen Monitor is being used at the most prestigious Universities such as Harvard, UCSB, UC Berkeley, and Cornell.

In addition to, a more recent sought out monitor has been their Methyl Bromide Monitor for fumigation. A monitor being sold for many years, also received an update in their software and hardware. Since 2008, PureAire received a EPA, DPR, and USDA compliancy for their safety methyl bromide monitor in the workplace. PureAire is the only company that makes a 24/7 supervised Ch3Br monitor used to measure in the ppm. Repeatable and reliable tests prove the monitor can be used to measure less than 1ppm. Low.4ppm or 400 ppb can be measured in areas containing methyl bromide gas. Before PureAire’s monitor, sampling tubes (Draeger or Kitagawa Colorimetric Tubes) were the only option to take a real time sample. To measure an air sample, an employee would need to take it him/herself. This ultimately brought up a safety concern for the employees, especially if there is a high concentration of methyl bromide in the area.

Primary areas where PureAire’s methyl bromide monitors are be sold are in cold storage facilities housing pre-fumigated produce before distribution throughout the country. For example, grapes are being shipped abroad to US ports. Before they are distributed to local grocery stores they are fumigated with Ch3Br in high concentrations eliminating pests, etc. Fumigation also ensures the produce is safer before being sold to consumers. The monitors are also used for the residual fumigation of walnuts, asparagus, avocados, apples, and strawberries

Also, PureAire is working on a multi point methyl bromide monitor which is in pre-production stages, hoping to be released to the public in the first quarter for 2012. This will be a 4 channel monitor for clients interested in monitoring 4 separate areas. As PureAire continues to grow, so will the development of newer and edgier products.

PureAire’s Oxygen Monitor uses a 10 + Zirconium Oxide O2 Sensor: Unlike the 1000 C degree Stack O2 sensors.

PureAire makes an Oxygen monitor for laboratories where nitrogen, helium, argon, carbon dioxide, and any cryogenic gases are stored. The O2 monitors are a standalone wall mounted unit with a built in audible alarm. The monitor utilizes a 10 + year Zirconium Oxide (ZrO2) sensor and has a backlit digital display showing readings of 0-25% range. PureAire has sold there O2 monitors while combining a ZrO2 sensor since the company started in 1997, and has contributed to their growth of 50% in 2011.

There are two types of ZrO2 sensors: There is a high temperature sensor (1000 C) for stack Oxygen monitoring, and a low temperature sensor PureAire uses. PureAire uses an Oxygen sensor that has a operational temperature near 400 C. Though this seems hot, the zirconium oxide sensor is quite stable and long lasting at this temperature.

The ZrO2 sensors (1000 C) commonly used for Stack O2 readings only have a life expectancy of 2-3 years. The contributing factor is the high temperatures achieved to gain there readings. PureAire utilizes a similar technology, but due to the lower (400 C) operational temperatures PureAire can increase their life expectancy to 10 years and more.

The ZrO2 oxygen sensor is very similar to the O2 sensors in automobiles for combustion. Every car has a O2 sensor and due to the long life expectancies, this is why automobile manufactures use them.

PureAire continues to strive for perfection. To maximize the most from their oxygen monitors, many years of R&D had to take place. The driving force behind developing the best oxygen monitor was the vision of making a monitor that would last for many years, and be easy for the consumer. Besides their main selling point of having a no maintenance O2 monitor, they have given the user a joystick for maneuvering  through the menus. It is responsive while working through the menus, and easy to adjust simple functions such as alarm set points.

The researchers at PureAire wanted to make it a point that nobody should confuse the two technologies of zirconium oxide sensors. While PureAire’s O2 sensor does seemingly have a high operational temperature, all automobiles use a similar technology and nobody seems to think twice about them.

PureAire has been trying to educate people about this technology for years, and companies are starting to recognize them as an industrial O2 monitor leader. 

While there are more than 2,000 PureAire oxygen monitors are in the field, people are still becoming aware every day. PureAire’s goal is to be the leading manufacture O2 monitors for 0-25% and if 2011’s growth has anything to show for it, I think they will.

PureAire Makes Oxygen Monitor for Nitrogen Generators.

Nitrogen generators are most commonly used in areas where on-demand nitrogen is preferred rather than, storing liquid nitrogen (LN2) in cylinders.  Nitrogen generators have a lower cost of operation, and can be used where smaller amounts of nitrogen are needed. Nitrogen generators are used in the pharmaceutical industry, testing laboratories, cryogenic facilities, welding manufactures, and petrochemical environments.

The question often comes up from a safety standpoint, is nitrogen a safe? The answer is usually no. An Oxygen Monitor is needed where LN2 or nitrogen generators are stored.  Nitrogen makes up roughly 70% of the air we breathe, though oxygen is only 20.9%. Oxygen is a precious gas that we take for granted. Ultra pure 99.9% nitrogen is unsafe in confined spaces, and nitrogen generators are usually stored in these types of areas. PureAire has developed an Oxygen Monitor with a 10+ year sensor made specifically for nitrogen storage areas, and nitrogen generators.

PureAire’s O2 Monitor uses a called Zirconium Oxide sensor. Most Oxygen Monitors use a disposable electrochemical sensor that typically only has a life expectancy of 12-18 months along with other complications. Some examples of problems with the electrochemical sensors are: drifts to thunderstorms, or barometric pressure changes, humidity changes, and temperature fluctuations.

PureAire has pioneered the way using a zirconium oxide oxygen sensor. The technology used is far more advanced than the “Old style,” electrochemical sensors. The sensor used is based on ions being passed through the sensor, and at 20.9% oxygen a certain quantity of ions cross the sensor. Thus, giving a current to the monitor giving an accurate reading between 0-25%.  If the oxygen concentration has been lowered, fewer ions cross the sensor hence, lowering the reading on their display. Intuitively, if there is higher known concentration of oxygen, so will the sensors readings on the PureAire Oxygen monitor.

The crucial understanding of the sensor is what gives PureAire’s clients the 10+ life expectancy and accuracy.  Another great property of the ZrO2 sensor is NO CALIBRATION is required. The sensors ion technology limits the need to calibrate. PureAire’s Oxygen monitor does not have problems with barometric pressure, temperature, or humidity changes. PureAire’s O2 Monitors are completely stable     (-40c to 50c) in all environments.

Nitrogen generators create high pressure in the cylinder after the gas has been created. This can be dangerous especially, overnight while employees are not in the proximity. PureAire also has a feature called latching. If there is a leak overnight, the alarm can stay alerted until the client turns off the switch in the morning.

PureAire is also looking for distributors to help distribute their oxygen monitors. In the past year PureAire has grown 50% and is continuing to gain more recognition. The demand for the O2 monitors has been more abundant exponentially. The PureAire ion based technology O2 monitor should be the only monitors being sold for 0-25% due to the lack of maintenance and calibration.

PureAire Oxygen Monitor Lights the way to Safety with 10+ Year Sensor.

Gas leaks are among the most common risks when storing or using liquid nitrogen, helium, CO2 or argon cylinders in a confined space. With inert cryogenic gases, loose or broken fittings can leak gas into a room, displacing oxygen, causing impaired judgment or loss of life to workers. To guard against this potential situation, oxygen deficiency monitors are ideal in the workplace. Specifically, PureAire, a supplier of oxygen deficiency monitors, offers a monitor that uses a non-depleting zirconium oxide sensor that has a 10+ year sensor life and requires no calibration or periodic maintenance.

According to Air Liquide and Irish Oxygen’s Nitrogen Safety Sheet, “cryogenics are mostly stored in confined spaces such as offices, freezers or hallways. One of the most overlooked additions to having LN2, He, Ar or CO2 cylinders ranging from 25 to 250 lb is the O2 monitor. MSDS sheets all have a variation of information mentioning high pressure and suffocation with no odor. In high concentrations, asphyxiation occurs with no warning. Symptoms may include loss of mobility/consciousness and [workers] must apply artificial respiration if breathing [has] stopped.”

The rapid release of nitrogen and various other cryogenics show absolutely no signs of immediate danger. NIOSH and OSHA state anything under 19.5% oxygen is considered hazardous and a dangerous environment for employees. The earth is a wonderful source of calibrated oxygen and we breathe 20.9% of it. PureAire’s oxygen detector is one of the most widely used real-time monitors for detecting leaks among cryogenic gas cylinders in storage rooms. If a gas spill or leak occurs, PureAire’s oxygen monitor is designed to turn on strobes and audible alarms to warn workers to evacuate the location. It also has built-in relays that can active ventilation fans to bring in fresh air.

PureAire’s oxygen monitor uses a 10+ year zirconium sensor, requiring zero maintenance and calibration. Because of its lasting electrochemical sensor, unlike other monitors that may use depleting ones, PureAire’s Oxygen Monitor helps labs save money in the long-term. Additionally, built-in “supervised watchdog” software continuously monitors all instrument functions 24/7. It is not affected by humidity, temperature or changes in barometric pressure, including changes caused by thunderstorms.

PureAire's Oxygen Monitor for Liquid Nitrogen Storage uses a 10+ Year sensor.

PureAire Monitoring Systems manufactures a variety of safety gas monitors, including the top selling oxygen monitor. PureAire’s oxygen monitors are used in areas containing liquid nitrogen, bulk nitrogen, or nitrogen Dewar storage. Recently, there has been a heightened awareness of nitrogen dangers in confined spaces, and ultimately an increased demand for fixed oxygen monitors. For years oxygen monitors have been used in confined spaces, but portable monitors were primarily used. Fire marshal’s, EH&S officers, and safety departments are now requiring companies to use oxygen monitors in almost all areas containing nitrogen tanks.

Typical facilities using LN2 (liquid nitrogen) are nitrogen manufacturers laboratories, semiconductor, cleanrooms, cryogenic freezers, food industries, NMR (nuclear Magnetic resonance) suites, cryopreservation, and confined spaces. Recently, PureAire has been working with companies like Praxair, Air Liquide, Air Gas, and Air products to help distribute to their clients. They believe PureAire has an alternative that is unlike anything else they have seen in the industry.

PureAire’s oxygen monitor uses a unique ZrO2 sensor with a 10+ year life expectancy. Also, more importantly the sensor is linear from 0-25%. If a client’s criterion requires seeing 15% oxygen, PureAire’s oxygen monitor will be accurate within .1%. The proprietary electronics is the backbone of the oxygen monitor. Other ZrO2 oxygen monitors exist though can only see an accurate reading at 20.9% due to lack of its electronics package.

Numerous tests have showed PureAire’s oxygen monitors readings are comparable to very expensive Oxygen monitor analyzers in the percent range. Though not marketed as an analyzer, if the client needs a cost competitive real-time monitor in the percent, nobody can match the precision PureAire’s oxygen monitor offers. Analyzers are accurate and dependable but are known for their constant calibration, and lack of real time monitoring.

PureAire requires no calibration, no replacement sensors, no maintenance, and no drifting to thunderstorms (change in barometric pressure).

Important questions to ask when purchasing a oxygen monitor? (This does not apply to PureAire)

1. How often do you calibrate a sensor?
2. How often do you replace a sensor?
3. How much does a sensor cost?
4. How long is the wait time to get a replacement sensor?
5. What is the shelf life of a sensor?
6. What happens if you do not calibrate a sensor?
7. What is the accuracy of the monitor?

Answer: Use a PureAire monitor.

PureAire Receives CE Approval on its Oxygen Monitor with 10+ Year Sensor.

PureAire Monitoring systems, the proud manufacture of their oxygen monitor has received a CE approval. The recent CE approval is monumental for PureAire selling to European countries. PureAire has been selling their O2 monitors in the USA for over 11 years. With a larger demand from their clients it was certain a CE approval would be beneficial to their product line, especially in Europe. PureAire’s oxygen monitor is highly revered for its 10+ year sensor requiring no replacement sensors, calibration, or maintenance.

When PureAire’s VP of Sales, Brandon Alan was asked, why is your O2 monitor different? Brandon explained the background of oxygen monitors; he discusses there is a lengthy maintenance process required to have a properly functioning monitor, until we, PureAire came out with the Aircheck Oxygen Monitor.

Brandon States, “About 95% of all Oxygen Monitor manufacturers use a continuous depleting sensor for O2 their readings. Clients will replace sensors on average from 12-18 months at $250 per sensor, and requires quarterly calibrations if their lucky. We have overcome the burden for our clients, and have provided an O2 monitor that is ultimately hassle free by using the zirconium oxide sensor. Gaining recognition of PureAire’s oxygen monitors has been an uphill battle, but companies are catching on quickly.”

So, where might you find Oxygen monitors being used?

Brandon: “Oxygen monitors are used in areas where the client may be worried for their safety due to a potential low oxygen level. More recently MRI rooms have been a risk due to the helium storage in the large magnet MRI scanners. Most people are not aware of the risks associated with helium. Most people joke if there was a leak of helium, they would talk like Mickey Mouse. Though, I do find humor in high talking Walt Disney characters, this can be a very serious matter. Our typical oxygen monitor client uses liquid nitrogen cylinders, nitrogen dewars combined with confined spaces, and laboratories containing cryogenics. The three largest Cryogenic gases (Oxygen depleting gases) are Nitrogen (N2), Argon (Ar), Helium (He), and Carbon dioxide (CO2).”

How do you see the CE approval helping your oxygen monitors sales?

Brandon: “I anticipate once the message gets out that we have a CE approval, European companies will start to take notice of our monitors. We understand in order to sell our products to other European countries we must have an approval. I am hoping companies will use our oxygen monitors based on our technology. Were hoping the old throw away sensor technology becomes an idea of the past in Europe, and our O2 monitor with 10+ year sensor becomes the product for the future.”

Oxygen (O2) Monitors: Disposable Sensors eating your Cash? PureAire Introduces 10 + Year Sensor.

[stx-pa-gas-monitor] PureAire Monitoring Systems is a leading manufacturer in the gas monitoring industry. When it comes to O2 deficiency monitors PureAire makes the most reliable, longest lasting, and affordable oxygen monitors.

It has been an international standard for the past three decades to use oxygen monitors with disposable sensor cells, (electrochemical sensors). All disposable sensors require frequent maintenance, monthly and quarterly calibration (false alarm if not calibrated), and usually drift to changes in barometric pressure. At PureAire, we made a point to fix this familiar problem and offer you a solution. We created a better product, one that eliminates the inconveniences of disposable sensors while continuing to meet your needs.

The 10+ Year O2 Deficiency Monitor is a unique product offered by PureAire. The Zirconium Oxide (ZrO2) sensor is the key technology that has allowed us to continue providing reliable and long lasting monitors over the years.

The ZrO2 sensor does not rely on partial pressure, or need a reference gas like disposable sensors. Also, our sensor does not require electrolyte, a depleting source of power, while disposable sensors require this fluid to give the sensor its power. Our sensor’s power comes from 24VDC, and does not have a depleting source. PureAire’s 10+ Year 02 Deficiency Monitor is much more reliable, requires no maintenance, and does not need to be calibrated. There zirconium sensor does not have the biases associated with the disposable sensor technology. This means no more false alarms and drifting, and an always-accurate reading.

With over 1,000 monitors in the field, PureAire continues to gain support amongst its users with a hassle free O2 monitor for safety. With our O2 Monitor you can be assured if there is a leak from any cryogenic gas (LN2, He, Ar, and CO2), our built-in audible will go off without any false alarms.
