HEALTH 3 Short exposure could cause serious temporary or moderate residual injury (e.g. liquid hydrogen, sulfuric acid, calcium hypochlorite, hexafluorosilicic acid)
FIRE 4 Will rapidly or completely vaporize at normal atmospheric pressure and temperature, or is readily dispersed in air and will burn readily. Includes pyrophoric substances. Flash point below room temperature at 22.8 °C (73 °F). (e.g. acetylene, propane, hydrogen gas)
REACT 0 Normally stable, even under fire exposure conditions, and is not reactive with water (e.g. helium,N2)
SPEC. HAZ.

Other Information

Density of the liquid at boiling point: 0.42 kg/l.High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.Check oxygen content before entering area.Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.After use for welding, turn valve off; regularly check tubing, etc., and test for leaks with soap and water.The measures mentioned in section PREVENTION are applicable to production, filling of cylinders, and storage of the gas.Other UN number: 1972 (refridgerated liquid), Hazard class: 2.1.
