Nitrogen - N2

Find here the essential information on nitrogen (N2): characteristics, effects on health, detection devices & systems (nitrogen gas detector or rather O2 gas detector) and proper respiratory protective equipment (self-contained breathing apparatus or air supplying respirator).

Nitrogen (N2) properties

Because of its properties under its liquid or gaseous state, nitrogen (N2) is used for many applications. It is applied to create inert atmospheres in tanks to protect products inside. In art, it is used as a soft pesticide to remove organisms living in wood. Moreover, as it is non-flammable, it is combined with carbon dioxide for firefighting.

Nitrogen effects on health

Contrary to asphyxating gases that cause suffocation replacing oxygen in blood, nitrogen is an anoxic gas. This means that it does not replace oxygen in blood but reduces its quantity, which leads to brain asphyxia and major organs dysfunction. Present at 78% in breathable air, its reduction can absolutely not be detected without proper equipment. That's why this gas is extremely hazardous.
