Oxygen in the air is typically 20.8% When nitrogen concentration increases, oxygen concentration decreases. Note: any compressed gas can also decrease O2 concentration in an enclosed space by replacing O2.4cb  !Facts & Figures -Liquid nitrogen" One litre liquid gives 700 litres of gas Cold nitrogen is heavier than air so accumulates at ground level. When liquid N2 is exposed to air the cloudy vapour that you see is condensed moisture, not N2 gas. N2 gas is invisible and this is the Danger!!!. OHSA recommend at least 6 changes of air per hour when using liquid N2. Other nitrogen risks: pressure, frost, confuse LEL detectors.2 J> Medical definitions Osmosis: If you have a concentrated mixture on one side of a permeable membrane and a dilute mixture on the other, the flow of material will be from concentrated to the dilute side. Hypoxia : reduction of O2 supply to the tissues Anoxia: lack of O2 supply to the tissues.@)$ Transport of oxygen   Oxygen Osmosis  *What happens when you breathe in nitrogen?+  Physiological effects (How long does it take to have an effect?) When a person enters an oxygen deprived atmosphere the oxygen level in the arterial blood drops to a low level within 5-7 seconds. Loss of consciousness follows in 10-12 seconds. Heart failure and death ensue if person does not receive any oxygen in 2-4 minutes.  What If I hold my breath? Holding your breath causes the oxygen in your blood to be used up. If you then inhale the inert atmosphere, suffocation and death will follow in most cases (INRS ED 632) 3Do I have to be in an enclosed space to be at risk?4 No. Any situation where you can breathe oxygen deficient air has the same effect. Incident at Texas City where individual was working on top of reactor. He leaned over, got a blast of pure N2 and pitched forward into the vessel unconscious. Cold nitrogen is more dense than air so lower concentration at floor level. If you lean down into a liquid nitrogen spillage you are also at risk.  -The last word& . -What if I see a colleague who is unconscious?. Call emergency services. - First as with all incidents Do not enter the area without self contained breathing apparatus. Over 50% of workers who die in confined spaces are attempting to rescue other workers. o  ` f` f>?" dP@$?" dd(@  " @e ` n?" dd@   @@``PZ   @ ` `p>>   c[(  f  0 "  Np| "Q  y9Click to edit Master text styles Second level Third level!   :  H "  b*   H "   d*    Hl‡ "0E  d*    N "n   T Click to edit Master title style! !
