Principle Routes of Exposure

Inhalation

Potential Acute Health Effects

Eyes : Contact with rapidly expanding gas may cause burns or frostbite. Contact with cryogenic liquid can cause frostbite and cryogenic burns. Skin : 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. Medical conditions aggravated by over- exposure : Acute or chronic respiratory conditions may be aggravated by overexposure to this gas. See toxicological information (Section 11)
