Asphyxiation prevention begins with an accurate and reliable room air oxygen monitor to assure personal safety.

Too often Nitrogen is the cause of Oxygen Depletion or Asphyxiation in the work place.

Nitrogen gas itself is not poisonous, as the air we breathe contains approximately 78% nitrogen, 20.9% Oxygen, and trace amounts of all other gases that make up the remaining 1%. However, if sufficient liquid nitrogen or other Cryogenic Material vaporizes from a pressurized container into a poorly ventilated work space it can easily reduce the oxygen level to below 20.0%.

Personnel in that space are in critical jeopardy due to rapid oxygen deprivation. Rapid venting can cause rapid displacement of normal air, leading to a local concentration of nearly 100% nitrogen or other Cryogenic Material.

Inert gas asphyxiation is a form of asphyxiation which results from breathing a physiologically inert gas in the absence of oxygen, or a low amount of oxygen, rather than atmospheric air. Examples of physiologically inert gases, which have caused accidental or deliberate death by this mechanism, are argon, helium and nitrogen. The term "physiologically inert" is used to indicate a gas which has no toxic or anesthetic properties and does not act upon the heart or hemoglobin. Instead, the gas acts as a simple diluent to reduce oxygen concentration in inspired gas and blood to dangerously low levels, thereby eventually depriving all cells in the body of oxygen.

According to the U.S. Chemical Safety and Hazard Investigation Board, in humans, "breathing an oxygen deficient atmosphere can have serious and immediate effects, including unconsciousness after only one or two breaths. The exposed person has no warning and cannot sense that the oxygen level is too low.

Make sure you purchase the highest quality and reliable oxygen analyzer for you employee safety and wellbeing.
