Safety Profile
Poison by ingestion and intraperitoneal routes. Moderately toxic by skin contact. Mddly toxic by inhalation. Human systemic effects by inhalation: olfaction effects, eye effects, and respiratory effects. A skin and eye irritant. Mutation data reported. Chronic exposure has produced injury to lungs, liver, and kidneys in experimental animals. Questionable carcinogen. Dangerously flammable when exposed to heat, flame, or oxidzers. Dangerous explosion hazard in the form of vapor when exposed to heat, sparks, or flame. Can react vigorously with oxidzing materials. A storage hazard; it forms peroxides, which may initiate exothermic polymerization. To fight fire, use foam, COa, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.
