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.

We 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,

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.

Our Oxygen deficiency monitors 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, our this monitor and sensors offer the unbeatable combination of reliability and performance.

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.

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.

Our 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.

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 MRI rooms.  Our oxygen monitors are a trusted product amongst MRI designers and users, thanks to their 10 + year oxygen sensor.  Unlike the competitors, our 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.
