Nitrous Oxide

SECTION 2: Hazards identification

Physical state : Gas. [COLORLESS LIQUEFIED COMPRESSED GAS. ODORLESS OR WITH A MILD SWEET ODOR. [INHALATION ANESTHETIC] [NOTE: SHIPPED AS A LIQUIFIED COMPRESSED GAS]] Emergency overview : DANGER! GAS: OXIDIZER. CONTENTS UNDER PRESURE. MAY CAUSE TARGET ORGAN DAMAGE, BASED ON ANIMAL DATA. CONTACT WITH COMBUSTIBLE MATERIAL MAY CAUSE FIRE. Do not puncture or incinerate container. Can cause rapid suffocation. May cause severe frostbite. LIQUID: Extremely cold liquid and gas under pressure. Do not puncture or incinerate container. May cause target organ damage, based on animal data. Store in tightly-closed container. Avoid contact with combustible materials. Contact with rapidly expanding gases or liquids can cause frostbite. Target organs : May cause damage to the following organs: the reproductive system, upper respiratory tract, central nervous system (CNS). Routes of entry : 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: A4 (Not classifiable for humans or animals.) by ACGIH, 3 (Not classifiable for humans.) by IARC. MUTAGENIC EFFECTS: Not available.

Teratogenic Effects

Not available Medical conditions aggravated by over- exposure : Pre-existing disorders involving any target organs mentioned in this MSDS as being at risk may be aggravated by over-exposure to this product. See toxicological information (section 11)
