Introduction Oxygen Depletion, also known as oxygen deficiency, is a serious safety issue that occurs when the oxygen concentration in an environment falls below the level necessary to sustain human life. The Occupational Safety and Health Administration (OSHA) defines an environment where oxygen levels fall below 19.5% as an oxygen-deficient atmosphere, which should be treated […]

Understanding Oxygen Deficiency The air we breathe is made up of 78% nitrogen, 21% oxygen, and trace amounts of other gases such as carbon dioxide, neon, and hydrogen. The oxygen level in the air we breathe is approximately 20.9%. A drop in oxygen levels below this percentage indicates an oxygen-depleted environment that poses significant health and […]

To create that perfect glass of wine, refreshing sip of water, or other non-carbonated drinks of choice, beverage producers often turn to liquid nitrogen (LN2). Liquid nitrogen fills an important role in the bottling and canning of non-carbonated beverages. What is Liquid Nitrogen? Liquid nitrogen is a cryogenic, liquefied form of nitrogen (N). Nitrogen is […]

MRI Magnetic resonance imaging (MRI) is a diagnostic procedure that uses a combination of a very large magnet, radio waves, and a computer to produce detailed, cross-sectional, and three-dimensional images of organs and structures within the body. An MRI scan is a valuable diagnostic tool that can show injuries or other anomalies that cannot be […]

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 […]

There is no question that working with inert gasses can be a useful but dangerous practice. Ideally, there should be an oxygen deficiency monitor in your facility to make sure the air is safe to breathe in case of a gas leak. If your facility is in Denver County, and you don’t yet have an […]

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. […]

As a recognized leader in O2 safety monitoring, PureAire recently explored the need for an O2 monitor where carbon dioxide is used. There are four key cryogenic gases; nitrogen, helium, argon, and carbon dioxide (CO2), which can create an oxygen deficient atmosphere. Material Safety Data Sheets (MSDS) covering cryogenic gases cite that a cryogenic leak […]
