Safety

Poison by ingestion, intraperitoneal, and intravenous routes. Moderately toxic by inhalation. Human systemic effects by inhalation: conjunctiva irritation, cough, and unspecified respiratory system effects. A human skin and eye irritant. Human exposure data suggest relatively low systemic toxicity, but intense irritation of eyes, skin, and mucous membranes. Mutation data reported. A tear gas used for riot control. When heated to decomposition it emits very toxic fumes of Cl−, NOx, and CN−.
