Oxygen depletion occurs when an inert gas like Nitrogen or Argon
displaces Oxygen levels.
Such a leak will quickly displace Oxygen and the atmosphere can
become unbreathable. Breathing air contains 21% Oxygen, if the level of Oxygen
decreases by as little as 1.5%, the human body wiill be affected. To find out

To combat this problem, Analox have developed
the Analox O2NE Oxygen depletion monitor, providing audible and visual
alarms to falling Oxygen levels.
