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.

Why a CO2 Monitor May be Needed? Where Carbon Dioxide leaks Occur

Do you work with carbon dioxide (or CO2) in your industry? If so, then you may need a carbon dioxide monitor to check for gas leaks that could pose a hazard to your workplace safety. Learn common scenarios where carbon dioxide can leak and see how a CO2 detector can minimize your risk.

Industries Where CO2 Monitors Can Make a Difference

There are many industries that utilize carbon dioxide gas, and we believe that all of these could benefit from the presence of a carbon dioxide monitor. Industries where a CO2 detector can make a difference include:

• Restaurant/fast food - Does your restaurant or fast food chain have a soda machine? If so, then you rely on carbon dioxide gas to pass through water, mix with flavored syrup, and create carbonated soda. When everything works properly, you can easily serve sodas. When the carbon dioxide line develops a leak and CO2 gas enters the premesis or gets into the sodas, you can sicken employees and customers. In a worst case scenario, you could be liable for the death of customers due to CO2 exposure.
• Convenience stores and gas stations - Convenience stores and gas stations using soda machines can benefit from a CO2 detector for the same reason as restaurants and fast food chains.
• Craft brewing - CO2 gas in a natural byproduct of the brewing process, creating fizz as yeast eats natural sugars. The CO2 is usually contained within the fermentation tank; however, the carbon dioxide could escape through the tank's airlock and valves. CO2 is heavier than air, so it can rest on the brewery floor where staff breathe it in. A CO2 gas detector can alert brewery staff to escaped gas, preventing a workplace catastrophe.
• Agriculture - Since grain gives off carbon dioxide gas in the silo environment, grain elevators have a need for CO2 detectors for worker safety and quality control. Even low levels of carbon dioxide can indicate grain spoilage. Early detection can not only protect the crop but safeguard worker health.
• Firefighters - Firefighters knowingly face danger to keep society safe from devastating fires, but they also face dangerous CO2 gases. Certain types of spray foam insulation that contain Icynene foam produce carbon dioxide gas in a fire. Firefighters also stock carbon dioxide canisters for use in firefighting, as the gas can be used to put out fires since it reduces environmental oxygen. If CO2 canisters develop leaks, or crews enter an environment that contains Icynene foam, firefighters risk breathing in dangerous fumes. A CO2detector can help crews monitor their risk on the job.
How CO2 Gas Monitors Can Help
If staff could see or smell carbon dioxide, they would be able to protect themselves and your customers. Unfortunately, this gas is odorless and colorless - a silent killer. There is no way for staff to tell whether systems are working properly or whether CO2 gas is leaking into the work environment. A carbon dioxide detector is a quick and easy way to tell when something has gone wrong.

When a leak occurs, it will disrupt the levels of oxygen in the air, ultimately creating an oxygen deficient environment. When there is not enough oxygen in a room, employees will begin to experience respiratory problems. The risk of death increases the longer staff remain in an oxygen deficient room.

A carbon dioxide monitor will detect levels of oxygen in the air round the clock, so no one needs to set it after the initial installation. When everything is functioning well, the alarm remains silent yet alert. The CO2 gas monitor will sound an alarm when levels of oxygen in the room reach the lower limit of the safe zone. Employees will hear and see the alarm, and can safely evacuate the space for their own health.

CO2 gas monitors from PureAire are equipped with zirconium sensors, which can last for 10 years without maintenance. Our products are reliable, well-constructed, and built to last in high-traffic retail and industrial environments. When safety matters, choose the best in oxygen monitoring equipment.

Paint Booths, or Areas Using Combustible Gases: Why a Requirement for Combustible Gas Monitor Might be Necessary

Paint booths save time and ensure a smooth and professional application of paint in a range of industries, including automotive, aerospace, home decor, furniture, and more. Combustible gases and fluids in the paint booth environment can pose a health hazard if something goes wrong. Explore the hidden dangers of paint booth fluids and gases, and learn how a combustible gas detector can increase employee safety in the work environment. 

Hidden Dangers in the Paint Booth Environment

The paint booth serves as a protected environment, minimizing many of the problems that would occur if the same item were to be painted out of doors. While paint booths are highly useful and cost effective for a range of applications, they do utilize harmful gases and fluids. Gases and fluids in a typical paint booth environment include compressed air, carbon dioxide, nitrogen, methane, natural gas, kerosene, helium, and custom gas mixes. These gases and fluids are usually piped into the spray booth from an external source; yet in some cases these gases can be piped into the spray booth from a source located inside the building. 
When everything is working properly, gases can flow as needed without posing a health risk. Yet if one of the supply lines, pipes, or storage tanks were to develop a leak, one or more of these substances could leak into the air. There are a range of hidden health dangers. Flammable gases, in contact with oxygen, could pose a fire risk. A lower explosive limit or LEL monitor can alert staff if gases have escaped so that staff may take appropriate measures. 

Nitrogen poses a severe health risk as it can create an oxygen deficient environment. When oxygen drops below a certain level, employees can experience respiratory distress. Since nitrogen is colorless and odorless, staff have no way of knowing of the danger they may be in, unless there is an oxygen monitor in place. 
The protected environment of the paint booth keeps contaminated air from passing through the area, so that the piece can properly dry and cure in between coats. This streamlines the spray paint process to ensure consistency and precision. 

When everything functions as it should, the paint booth ventilation controls keep vapors in the mist below 25 percent of exhaust. While routine inspections and internal alarms can ensure you that everything is working well, they are not a failsafe. To protect your staff from the dangers posed by combustible fluids and gases, install a combustible monitor and an O2 monitoring device as a second line of defense. 

How an LEL Combustible Monitor Can Protect Your Staff

The presence of combustible gases makes paint booths a dangerous environment prone to fires and explosions. To mitigate the risk, special pipes are used to carry materials into and out of the environment. Instrumentation and temperature controls utilize explosion-proof components, which ensure that the instrumentation and controls create no spark.

While this reduces the risk of explosion, it does not reduce the danger these gases pose were they to leak into the closed environment of the paint booth. An LEL monitor alerts your staff if gases exceed the lower explosive limit. This gives staff enough time to shut off control valves and exit the paint booth environment, safeguarding their health and reducing the risk of explosion. 
Not only are these monitors a good idea for employee health and safety, they may be required by law. According to OSHA, the Occupational Safety & Health Administration, a compliance safety and health officer can use a combustible gas monitor during inspections to ensure that the work environment does not pose a threat. 

PureAire offers a range of O2 monitoring systems for Nitrogen, Argon, CO₂, and helium. Also, they offer LEL monitors that can be used to monitor the levels of hydrogen, natural gas , acetylene, and other combustible gases in the environment.  Built to withstand regular use without the need for maintenance, our combustible gas detectors come with a 4+ sensor and two alarm relays.

PureAire has over 15 years of experience developing the latest in LEL and oxygen monitors for a wide range of industrial uses. When you need a reliable and durable safety monitor, choose PureAire.

Oxygen Monitor for Foup's in Semiconductors and Cleanrooms

Over time, the contamination control requirements in the semiconductor industry have become more stringent. Employees now must spend more time adhering to cleaning protocols to preserve the sanitary nature of the environment and comply with regulations. The front-end unified pod (or FOUP) began appearing in semiconductors in the 1990s, serving as a transportation box to safely and securely hold silicon wafers and ensure easier compliance with the industry's  contamination control requirements.

FOUPs allow the wafers to remain in a sterile environment, while also remaining isolated from the cleanroom itself. Not only does this save time, this saves money by lowering the maintenance needs and investments needed to maintain a clean room. Widespread today, FOUPs must be properly cleaned and maintained in order to remain functional. Since a single FOUP can cost $1,000’s so this is not something to be taken lightly by staff. 

Why Cleanliness is Critical to the Semiconductor Industry

Maintaining a cleanroom is so important because air particles can get on equipment or tools and compromise them. During manufacturing processes such as etching, the wafers held inside FOUPs are removed from the isolated environment of the FOUP and then subject to different chemicals. After the etching process ends, trace amounts of these chemicals remain on the wafers. If these were to be returned to the FOUP, they would contaminate the closed atmosphere with chemical residue. This could wreak havoc on the remaining wafers stored in the clean environment of the FOUP. Were this to happen, FOUPs and the wafers inside would need to be cleaned - a very expensive and time consuming process. 

The average FOUP can last for roughly five years before it needs to be replaced. To extend its lifespan and keep all components clean and sanitary, it is necessary to clean FOUPs periodically and to maintain good laboratory habits to minimize mishandling of FOUPs.

Compressed dry air or an inert gas such as nitrogen are common choices for effective cleaning of FOUPs. Studies have shown that passing nitrogen gas over the lower ports and front-end environment of the FOUPs is a reliable way to clean the interior by removing debris and chemical residue stuck inside. While this is useful for reliable FOUP cleaning, introducing nitrogen into the laboratory environment can pose a safety hazard.

Safety Risks of FOUP Cleaning With Nitrogen

Nitrogen gas can displace oxygen if it is released in a closed environment. Were nitrogen to leak from the FOUP and into the clean room, it could reduce levels of oxygen in the air below safe breathing levels. In a worst-case scenario, staff could become sick or die from lack of oxygen. Since both oxygen and nitrogen are colorless and odorless gases, staff cannot tell how much oxygen is in the air, or whether nitrogen used to clean FOUPs has escaped through a leak.
An oxygen monitor can evaluate the levels of oxygen in the air to ensure that nitrogen used to clean FOUPs does not make its way into the clean room, to compromise the air quality and safety there. A wall-mounted O2 monitor takes periodic readings of the level of oxygen in the room. As long as oxygen levels remain in an acceptable range, the sensor will continue to operate as usual. 

If oxygen levels were to drop such that employee health and safety might be compromised, the oxygen deficiency monitor would set off an alarm that would tell staff to evacuate. Staff then have enough time to exit the clean room and avoid health problems associated with oxygen deficient environments. 

When looking for an oxygen monitor for FOUPs, it is vital that the O2 monitor be as hardy and long-lasting as the FOUPs themselves. At PureAire, we make oxygen sensors guaranteed to last for 10 years. Our O2 monitors do not need calibration or maintenance to perform, unlike other brands of oxygen monitors. To ensure a clean, safe environment, while protecting your investment, choose the best in oxygen deficiency monitoring. Learn more about our products at our website, www.pureairemonitoring.com.

Auotclaves and Nitrogen. Why an Oxygen Monitor may be Required for Safety

In many industries, including aerospace, autoclaves play an important role in the manufacturing process. Key components of aerospace systems need to be put under an intense pressure and temperature during their formation; at present, an autoclave offers the best and safest way to do this. However, the manufacturing process usually uses nitrogen to create high levels of pressure in the system and to sweep away off-gases created by the composite curing process. If a component malfunctions, this nitrogen could escape into the workroom and pose a health hazard. Learn more about how autoclaves utilize nitrogen and how an oxygen monitor may be required for employee safety. 

Autoclaves and Nitrogen: Nitrogen's Role in Aerospace Manufacturing

When composite parts are created and cured, the pressure in the autoclave environment puts them into a situation where they become highly flammable due to increased pressure and temperature inside the autoclave. 

Once cured, these parts are safe and do not pose a fire risk. However, during the curing process they could combust if the right conditions prevailed - namely, if oxygen were introduced. Nitrogen is favored for use in autoclaves since it is inexpensive to buy and is inert, thus will not catch fire. Nitrogen can safely remove these off-gases and reduce the risk of fire. However, the use of nitrogen in the autoclave brings about another set of challenges. Nitrogen must be kept in the autoclave and safely vented outside the room, since nitrogen creates an oxygen deficient environment when it mixes with pure O2. 

Since there is a safety concern with autoclaves, they are highly regulated by the American Society of Mechanical Engineers (ASME) code. The good news is, the pressure valves used on autoclaves are very safe, thanks to the conservative ASME guidelines. Every autoclave in use today has multiple safety valves, which ensure that pressure inside can be safely released. 

Even though autoclaves are subject to strict regulations, have built-in safety redundancies, and are generally considered to be very safe, accidents can still occur. One small step you can take to protect workers and prevent a tragedy from occurring is to invest in an oxygen deficiency monitor. 

How an O2 Monitor Keeps Workers Safe

If the nitrogen were to escape from the autoclave during the manufacturing process, it could actually deplete oxygen levels in the room. When oxygen levels go down, workers can have a difficult time getting enough air to breathe and may become dizzy or lightheaded as a result. Nitrogen has no odor or color, so these minor physical symptoms are the only clue staff may have that there is something wrong.

As nitrogen escapes it creates an oxygen deficient environment. When there is not enough oxygen to breath, your employees can suffocate and die in a worst case scenario.  

To keep your employees safe, you must make sure that all equipment is working properly by scheduling regular autoclave inspections and performing routine maintenance as scheduled. Additionally, invest in oxygen monitors in any area where you use autoclaves. These O2 monitors offer a simple, cost-effective way to keep track of oxygen levels in the room 24/7. 

An oxygen sensor or O2 monitor takes regular readings of the oxygen levels in the room. When oxygen levels are within the normal range, the monitor continued to function. If oxygen levels fall below the safest acceptable level, the monitor lets off an alarm that tells staff that there is a problem. Employees can then exit the room and avoid being exposed to an oxygen deficient environment and suffering grave and potentially fatal health problems. 

PureAire's oxygen sensors are guaranteed to last for a period of 10 years, thanks to their hardy zirconium construction. Whereas other types of oxygen deficiency monitors require regular calibration and maintenance, our products are reliable, guaranteed to perform over a test of time, and do not require staff maintenance. 

When you want the best in oxygen monitoring to keep your employees safe, look to PureAire, which has more than 15 years of experience creating O2 monitors.

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.
