TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion. Heating will cause rise in pressure with risk of bursting.	NO open flames, NO sparks, and NO smoking. NO contact with flammable substances. NO contact with fuels and other combustible materials.	In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION	Risk of fire and explosion on contact with combustuble materials such as oils or fats.		In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.

EXPOSURE
INHALATION	Burning sensation.		Fresh air, rest. Refer for medical attention.
SKIN	Pain. Serious frostbite. ON CONTACT WITH LIQUID: FROSTBITE.	Cold-insulating gloves. Protective clothing.	ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention.
EYES	Redness. Pain. Severe deep burns.	Safety goggles, face shield.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.

ENVIRONMENTAL
DATA

NOTES

Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered. 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. Also consult ICSC # 0138.
