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 combustible materials such as oils or fats.

In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.
