Nitrogen (N₂)
The inert gas used in a variety of applications including cutting, purging, cooling and freezing
Nitrogen is a non-flammable air gas that forms 78% of the earth’s atmosphere.
Valued for its inert properties in its gaseous form, nitrogen displaces air and therefore, reduces or eliminates the oxidation of materials. It is also used as an assist gas for laser cutting. Given the extremely low temperatures of its liquid state, nitrogen is an ideal gas for cryogenic cooling and freezing.

Safe Nitrogen Use
Nitrogen is odorless, colorless, tasteless, and non-irritating which means it has no warning properties and we can’t detect its presence. It is non toxic and inert, but can act as a simple asphyxiant by displacing oxygen in air to levels below that required to support life.
Personnel, including rescue workers, should not enter areas where the oxygen concentration is below 19.5%, unless provided with a self-contained breathing apparatus or air-line respirator.
