|Avoid release to the environment because of its impact on the ozone layer.|
|High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
Check oxygen content before entering area.
Physician should give special attention to the drugs used in treatment because of the effects of the substance on cardiac rhythm.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
