SECTION 2: Hazards identification

Physical state : Gas. Emergency overview : DANGER! GAS: OXIDIZER. CONTACT WITH COMBUSTIBLE MATERIAL MAY CAUSE FIRE. CONTENTS UNDER PRESURE. Do not puncture or incinerate container. May cause severe frostbite. LIQUID: Extremely cold liquid and gas under pressure. Do not puncture or incinerate container. Store in tightly-closed container. Avoid contact with combustible materials. Contact with rapidly expanding gases or liquids can cause frostbite.

Principle Routes of Exposure

Inhalation

Potential Acute Health Effects

Eyes : May cause eye irritation. Contact with rapidly expanding gas may cause burns or frostbite. Contact with cryogenic liquid can cause frostbite and cryogenic burns. Skin : May cause skin irritation. Contact with rapidly expanding gas may cause burns or frostbite. Contact with cryogenic liquid can cause frostbite and cryogenic burns. Inhalation : Acts as a simple asphyxiant. Ingestion : Ingestion is not a normal route of exposure for gases. Contact with cryogenic liquid can cause frostbite and cryogenic burns. Potential chronic health effects : CARCINOGENIC EFFECTS: Not available. MUTAGENIC EFFECTS: Not available.

Teratogenic Effects

Not available Medical conditions aggravated by over- exposure : Acute or chronic respiratory conditions may be aggravated by overexposure to this gas. See toxicological information (section 11)
