Safety Profile
Poison by ingestion, intraperitoneal, and subcutaneous routes. An experimental teratogen. Combustible when exposed to heat or flame. Decomposes exothermically above 195°C. Can react with oxidizing materials. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition, or on contact with acid or acid fumes, it emits highly toxic fumes of NOx and CN-. See also NITRILES.
