Safety Description:Poison by inhalation, ingestion, and skin contact. Human systemic effects by inhalation: conjunctiva irritation, olfactory and pulmonary changes. An experimental teratogen. Other experimental reproductive effects. Mutation data reported. A severe eye, skin, and mucous membrane irritant and a sensitizer. It can be absorbed through the skin. Exposure to high concentrations of the vapor can cause blindness; lung damage, including edema, permanent fibrosis, emphysema, and bronchitis; and gynecological effects. Most deaths are a result of lung tissue damage. This was the predominant cause of death in the release of MIC in 1984 at Bhopal, India. Effects of cyanide poisoning have been noted but this may be due to impurities. A flammable liquid and a very dangerous fire hazard when exposed to heat, flame, or oxidizers. To fight fire, use spray, foam, CO₂, dry chemical. Exothermic reaction with water. When heated to decomposition it emits toxic fumes of NO_x and CN⁻. See also ISOCYANATES.
