Nitrogen in a confined space
Web4.3.3 Asphyxiation in confined spaces Liquid nitrogen rapidly vaporises to gas with about 700 times the liquid volume. By displacing air in a confined space such as a passenger / service lift or motor vehicle the gas may kill by asphyxiation. When oxygen concentration in the air is low a person may become unconscious without warning symptoms. WebCommon toxic gases found in confined spaces include hydrogen sulfide (H2S) and carbon monoxide (CO). However, other toxic gases may be present could be present, therefore using a monitor that will allow you to accurate evaluate their levels before entry How to Monitor For Atmospheric Hazards in a Confined Space
