What Are Hot Melt Adhesives? Why Are They Used and What Is the Importance Of Nitrogen Gas?

 Hot Melt Adhesives and Available Types Used in Industrial Manufacturing

Industrial hot melt adhesives are polymer-based thermoplastic resins that, when melted, are used to bond materials together. Hot melt adhesives are comprised of one or more base polymers combined with tackifiers (which provide stickiness to the adhesive), plasticizers (to provide greater flexibility), and antioxidants (for protection against degradation) to allow for stability, adhesion, and flexibility.

Industrial hot melt is available in a variety of forms, including granular or powder hot melt blocks, pellets, bags, cakes, drums, and pillows. These materials are solid at room temperature, and then heated, melted, and dispensed for a variety of industrial applications.  As the adhesive returns to room temperature, a strong bond is created, adhering the manufacturing components together.

Hot melt can be dispensed as a liquid or, by introducing an inert gas (such as nitrogen) to the hot melt, as a foam.

Industrial Hot Melt Applications

In either liquid or foam form, hot melt adhesive is used across a wide variety of industries including  aerospace; automotive; product assembly; furniture making, cabinetry, and upholstery; product packaging; book binding; and non-woven sanitary hygiene products.

Aerospace and automobile manufacturers utilize hot melt adhesives for potting electronics (a process used to protect sensitive components from impact or vibration), as well as sealing rivets, seams, and joints. Additionally, hot melt foam is used in airplanes and cars as insulation around doors and windows to reduce vibrations and noise, as well as in seat assembly.

The pages in books and magazines are kept securely bound together using HMAs. The packaging industry depends on a strong adhesive bond to keep the flaps of corrugated boxes and cartons securely closed.

Non-woven personal hygiene products are manufactured by utilizing hot melt adhesives throughout the manufacturing process, including adhering the elastic strands in the leg openings and waistbands, bonding the fabric layers together to secure and stabilize the wetness core, and affixing the fastening tapes to the waistband.

Charring

Charring is akey concern when working with hot melt adhesives, as char (degraded adhesives that have oxidized, hardened into a gel, and been blackened and burned) can negatively affect the adhesives, cause equipment failure, and lead to a shut-down in production.

Key causes of charring include overheating (typically as a result of either using a temperature that is too high for a particular hotmelt, excessive heating times, or incorrect melt tank size); oxidation (exposing the adhesives to too much oxygen), and contamination (from dirt, dust and other materials that fall into the hotmelt and burn).

Once formed, the char can break off into pieces that may clog filters and stop up spray and bead nozzles. The pieces of char can work their way onto the materials to be bonded, leaving marks, streaks, and uneven surfaces. Eventually, bits of char may get into hoses and pumps, breaking seals and scoring and damaging hoses and pump walls.

Why Nitrogen is Used for Hot Melt Adhesive

To reduce potential damage from charring, hotmelt operators may elect to blanket the adhesives with nitrogen (N2) in a process by which nitrogen, an oxygen depleting gas, is piped into the space between the hotmelt adhesive and the top of the hopper or melt tank. The nitrogen blanket protects the adhesive by creating a barrier against falling debris, and it also removes oxygen and moisture which may cause the hotmelt to oxidize and form char .

Oxygen Monitors Improves Quality Control and Helps Protect Employees

To preserve the integrity of the hot melt while blanketing with nitrogen, employees must maintain proper oxygen levels within hoppers or melt tanks, as too much oxygen can cause oxidation. Proper oxygen monitoring equipment should be placed inside melt tanks to measure and control oxygen levels.  A nitrogen leak could lead to failure of the nitrogen blanket, which could compromise the integrity of the adhesives.

Moreover, wherever nitrogen is used, the possibility of nitrogen leaks poses potential risks to humans. Since nitrogen displaces oxygen, a leak could deprive the air of oxygen, thereby creating a possible health hazard for personnel. When there is not enough oxygen in the air, persons working in the area can become disoriented, lose consciousness, or even suffocate due to the lack of oxygen. Since nitrogen lacks color and odor, there is no way, absent appropriate monitoring, for employees to detect a leak.

Best practice calls for oxygen deficiency monitors to be installed anywhere there is a risk of gas leaks. As such, oxygen monitors should be placed wherever nitrogen is stored, and in all areas where nitrogen is used.

PureAire O2 Deficiency Monitors

PureAire Monitoring Systems’ line of Oxygen Deficiency Monitors and Water Resistant Sample Draw Oxygen Monitors continuously track levels of oxygen and will alert hotmelt personnel to nitrogen leaks before employees’ health is put at risk.  In the event of a nitrogen gas leak, and a decrease in oxygen to an unsafe level, the monitor will set off an alarm, complete with horns and flashing lights, alerting employees to evacuate the area.

PureAire’s Water Resistant Sample Draw Oxygen Monitor is a self-contained oxygen deficiency system that is suitable for remote sampling of oxygen levels in confined spaces, hotmelt tanks, and other locations where remote oxygen monitoring is required. The built-in pump samples oxygen levels from up to 100 feet away.

PureAire oxygen monitors measure oxygen 24/7, with no time-consuming maintenance or calibration required. Built with zirconium oxide sensor cells to ensure longevity, PureAire’s O2 monitors can last, trouble-free, for over 10 years under normal operating conditions.Each PureAire O2 monitor has an easy to read screen, which displays current oxygen levels, for at-a-glance readings by hotmelt manufacturers, who derive peace of mind from the monitor’s presence and reliability.

NASA's Uses the Largest Airborne Telescope Observatory in the World

NASA's latest project, a joint collaboration with the German Aerospace Center, breaks new ground for scientific discoveries. The new Stratospheric Observatory for Infrared Astronomy (or SOFIA, as it's known) makes use of a modified Boeing aircraft and a reflecting telescope to enable spatial observations far more detailed than anything a land-based telescope could see. Get a sneak peak inside SOFIA and learn how an O₂ monitor plays a pivotal role in keeping SOFIA safe. 

SOFIA's Mission 

The airplane that powers SOFIA is a short-body 747, which is capable of burning through 3,600 gallons of jet fuel per hour. The plane has been extensively modified to support its new mission, which is to observe the universe using the infrared spectrum of light. This is light that is invisible to the human eye. Interestingly, many objects within space emit only infrared light, meaning that astronomers cannot perceive them with the naked eye. 

SOFIA uses a lot of specialized equipment to make these infrared emissions visible. The telescope on board has a 100-inch diameter. The instrument panel contains cameras, spectrometers, and photometers which operate along near, mid, and far infrared wavelengths to study different scientific phenomena. 

The telescope must be kept clean and properly chilled to see the infrared light. Bathing the telescope in liquid nitrogen keeps it properly chilled, so the telescope can detect midrange and far-out light sources. Nitrogen is used for both of these purposes because it is cost-effective, readily available, and will not damage the sensitive equipment. 

SOFIA will allow astronomers to observe star birth, star death, black holes, and nebulae. It's difficult to forecast what other findings SOFIA may facilitate. 

In some cases, distant objects are blocked by clouds of space dust, much like the sun can become blocked by clouds.  While the space dust prevents these far-off objects from being seem, their infrared energy still reaches SOFIA's powerful telescope. By studying the infrared light captured on SOFIA's instruments, astronomers can learn about new phenomena and come to a better understanding of complex spatial molecules, new solar systems, planets, and more. 

Why SOFIA Needs an Oxygen Deficiency Monitor 

One small but mighty piece of equipment onboard the special aircraft is an oxygen deficiency monitor. SOFIA's powerful telescope must be cooled with liquid nitrogen. The nitrogen storage tank is located inside the crew department. 

Nitrogen gas is heavier than oxygen. In the event of a leak, the nitrogen would actually displace oxygen molecules, causing the cabin air to become deficient of oxygen.

Oxygen-deficient air causes respiratory and cognitive problems within minutes, leading to death via asphyxiation. Since this gas has no color or odor, there is no way the crew can tell there is a leak onboard. This is where the O₂ monitor comes in: By taking continuous readouts of cabin oxygen, the oxygen monitor allows staff to check ambient oxygen levels at a glance. Staff receive peace of mind that everything is operating smoothly as well as a fast alert if oxygen approaches hazardous levels due to a leak of nitrogen gas. 

If a nitrogen leak does occur, the plane must make an emergency landing—aborting the mission to save the life of the personnel onboard. If something goes wrong while SOFIA is in flight, and the aircraft has to land before the mission is complete, the cost of wasted fuel is (pardon the pun) astronomical. 

Since there is so much riding on the oxygen monitor, NASA needed a reliable product, one that would not drift from changes in barometric pressure. While there are many oxygen deficiency monitors, several products on the market are sensitive to barometric pressure shifts. PureAire offers hardy O₂ monitors that are capable of maintaining reliable performance despite barometric changes. 

Our O₂ monitor lasts for 10 or more years after installation with no maintenance required, thanks to a robust zirconium sensor that outperforms the competition. After installation, our oxygen deficiency monitor needs no calibration to continue working accurately. If there is a nitrogen leak, the oxygen deficiency monitor provides two built-in alarms, which operate at 90 decibels. These alarms—which correlate to 19.5 percent and 18.0 percent oxygen—provide the SOFIA crew with sufficient notification of any problems, so they can return to safety. 

It's thrilling to have our products be a part of such a vital mission, and we cannot wait to see what new discoveries SOFIA facilitates. Closer to home, PureAire supports clients in a range of industries with high-value, long-lasting oxygen monitors suitable for use anywhere they are needed.

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.

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.

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.

PureAire’s O2 Monitor used in High Altitude Training Gains Recognition among Athletes

Since 2006 PureAire Monitoring Systems O2 Monitors have been used in Hypoxic High Altitude Training rooms. The training rooms are designed to lower the breathable oxygen using nitrogen, and the oxygen monitor is needed to maintain the environment. The technology used to lower the O2 level is used with a nitrogen generator. By lowering the breathable oxygen this creates a more strenuous workout for an athlete. The generator is important as it dispenses on demand nitrogen at any given time lowering the oxygen levels. For typical training, the oxygen levels are near 15% with the balance of nitrogen. At 15% oxygen the altitude system tricks the body to believe it is training around 8,000 ft above sea level. The O2 deficiency monitor operation range is 0-25%. PureAire’s O2 deficiency monitor was defined as the best product to maintain these stable oxygen levels. Hypoxico Altitude Training Systems is the first to start selling and marketing a product like this. PureAire’s oxygen deficiency monitor uses a zirconium oxide sensor. The monitor does not require maintenance or calibration. For these reasons, PureAire has been specified as the best fit for the altitude systems. The sensors life expectancy is 10+ years. In addition, the sensors are completely linear full scale of 0-25% giving an almost analyzer quality for the athletes. Some clients which have been reported to use these altitude training systems are Prince Harry, Lance Armstrong, David Beckham, Cleveland Indians, Bear Grylls, and Michael Phelps. On 60 minutes Michael Phelps talks about using an altitude tent, but said he did not want to show this room to cameras. Many other athletes use altitude training as part of their exercise routines as well. Altitude is characterized by the reduced partial pressure of oxygen. At a lower partial pressure, there is less oxygen in the air you breathe. It is this reduced oxygen content that stimulates the body to adapt and become more efficient in the uptake, transportation, and metabolism of oxygen. The HYPOXIC ALTITUDE TENT utilizes the same oxygen reduced air that one would find at high elevations. Our Hypoxic Generator continually separates out a portion of oxygen from ambient air before it is pumped into the enclosure. All other gases remain in the air, maintaining the atmospheric pressures of sea-level (or whatever altitude you are living at)1 The main O2 Monitor function which controls the desired training elevation, in the altitude room, is called hysteresis. Hysteresis is similar to how an air conditioner keeps a desired temperature range in one’s home. For example, if 70f degrees are set on a home’s air conditioner, when the temperature begins to rise to 71f, the temperature control (hysteresis) turns on the air conditioning lowering the temp back down to 70f. The PureAire O2 monitor has the same function. If the altitude room requires 15% oxygen, PureAire’s O2 monitors hysteresis will work similar to the air conditioner in a home. When the O2 levels rise to 15.5%, the O2 monitor will control the nitrogen generator lowering the O2 to the desired range of 15%. PureAire is the only O2 monitor being used for altitude training systems currently and with the growing amount of athletes training, PureAire believes only the demand for these training systems will go up in the future.

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.

The Beverage Industries Incorrect Way of Monitoring for CO2 leaks: Why CO2 Monitor is the Wrong Solution. Hear why PureAire’s Oxygen Monitor is a Bett

Carbon Dioxide (CO2) is the primary compressed gas used for beverages at major fast food chains. This gas is also used in restaurants, gas stations, and grocery stores. When CO2 leaks into a confined space or basement, this creates a very unsafe workplace for employees by lowering the breathable oxygen. History seems to repeat itself all too often while dealing with CO2. Due to the CO2 leaks several times a year, employees have become sick and in worst cast scenarios, have died from asphyxiation.

Below is a link to the Phoenix Fire Department video on a CO2 leak at a fast food chain. Two Fire men were overcome by CO2 in a basement of a chain. http://nfpa.typepad.com/fireservicetoday/2011/10/lesson-learned-co2-leak-at-mcdonalds-harmful-to-employee-and-responders.html

It has become a standard in the industry to use a CO2 monitor; this is outdated and should be replaced with an Oxygen Monitor. CO2 Leaks are a Oxygen deficiency problem as CO2 displaces oxygen creating an unsafe workplace. PureAire is a leader for oxygen monitors in the workplace for safety. PureAire makes an Oxygen monitor with a 10+ year sensor without maintenance, and calibration. This is very important advantage over the CO2 monitors being used.

The CO2 monitors installed in fast food chains are the wrong approach. The CO2 monitors used are low cost, and can do more harm than good. A gas monitor is a scientific piece of equipment. The technology used in the CO2 monitor requires maintenance, calibration, and monthly testing. Without oversight, the monitors will begin to fail or become unresponsive. The lacks of attention to the current CO2 Monitors are a common problem amongst the fast food employees.

Employees at fast food chains are not trained on compressed CO2 typically. Employees are the first people to work with CO2, and in most cases are required to change CO2 gas in a basement or confined space. What if there is a leak? What if the CO2 monitor is non functional? This result can be catastrophic.

PureAire believes strongly the answer is not a CO2 monitor, but an Oxygen Monitor. CO2 will always displace oxygen and will lower the breathable oxygen levels. PureAire’s Oxygen Monitor is unlike any other, using a 10 + year sensor which is 24/7 supervised. The O2 Monitor is safer and much more reliable. Using PureAire’s O2 Monitor will eliminate the concerns about CO2 spills. If there is a leak of Oxygen, the O2 Monitors alarm will sound alerting employees. PureAire‘s 24/7 supervision will ensure the monitor is functioning properly, and responsive when it is needed most.

PureAire’s knows you cannot always count on an employee’s knowledge of the CO2 risks, the signs of CO2 exposure, and the dangers of CO2. This is why PureAire’s monitor is the best choice. The monitor can also be configured with an exhaust fan, further enhancing the safety with complete automation.

Why the use of a CO2 monitor may not be the best solution for protecting workers against leaks from beverage dispensing systems in the fast food ind

Carbon Dioxide (CO2) is the primary compressed gas used forhttp://www.blogger.com/img/blank.gif dispensing beverages at fast food chains. This gas is also used in restaurants, gas stations, and grocery stores. When CO2 leaks into a confined space or basement, it creates a very unsafe environment for employees because it lowers the concentration of breathable oxygen. History seems to repeat itself all too often while dealing with CO2 leaks from dispensing systems. Due to numerous CO2 leaks in the workplace, lower oxygen levels have resulted in employees becoming sick or dying, from asphyxiation.

Below is a link to the Phoenix Fire Department video on a CO2 leak at a fast food chain. An employee and two firemen were overcome by a lack of oxygen due to a CO2 leak in the basement of a restaurant. http://nfpa.typepad.com/fireservicetoday/2011/10/lesson-learned-co2-leak-at-mcdonalds-harmful-to-employee-and-responders.html

The use of a CO2 monitor is accepted as a standard method in the industry, however since a leak actually creates an oxygen deficient environment; the use of an Oxygen monitor would provide better protection. CO2 displaces oxygen.

PureAire is a leading supplier of oxygen monitors for protecting people in the workplace. Its Oxygen monitor uses a proprietary non depleting sensor with a 10+ year life. The monitor requires no maintenance or the need for routine calibration; a very important advantage over the CO2 monitors being used.

The use of a CO2 monitor to protect people against oxygen deficiency in fast food chains can be the wrong approach since it’s the lack of breathable oxygen that is causing injury. Companies however are attracted to the low cost of CO2 monitors and since there is no regulation to use oxygen monitors, there is no incentive to provide better protection. Virtually every response to a CO2 leak resulted in a conclusion that workers were overcome by a lack of oxygen, which cannot be detected using a CO2 monitor.

PureAire believes that the use of a CO2 monitor alone cannot provide adequate protection to a leak. When storing large cylinders of liquid CO2 in confined spaces, complete protection should include an oxygen deficiency monitor.

Most users of CO2 dispensing systems do not have trained technical staff to maintain a monitoring system. All monitoring and system functions on PureAire’s oxygen monitor are 100% supervised and fault protected. Employees are always assured of continuous protection and are alerted to any failures.

The earth is a wonder source of calibrated oxygen and under normal ambient conditions of 20.9%, the monitor is continuously exposed to calibrated gas. CO2 monitors read zero when not exposed, and therefore require routine calibration to insure they’re working. This is not required for PureAire’s oxygen monitor.

In addition to its long life, no maintenance sensor, the oxygen monitor has built-in alarm relays for controlling ventilation fans or connecting to standard fire alarm panels. A major producer of CO2 gas actually uses PureAire oxygen monitors in their gas processing plant because of their concern of lower oxygen levels due to a CO2 release. We agree with them.

PureAire Monitoring Systems Grows their Sales Once Again

In the past year PureAire Monitoring Systems has grown at the rate of 50%. PureAire is known for the manufacturing and selling of safety gas monitors. There monitors are used in environments such as laboratories, pharmaceutical industries, medical laboratories, universities, nitrogen manufacturing plants, cold storage warehouses, and other various areas where air conditions can be at risk PureAire started in 1997 and has continued to develop new gas monitors for safety in the workplace. 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.
