SAFETY PROFILE：

Moderately toxic by ingestion. Experimental teratogenic effects. Questionable carcinogen with experimental tumorigenic data. Liver damage reported in experimental animals. A very dangerous fire hazard and moderate explosion hazard when exposed to heat or flame; can react vigorously with oxidizing materials. To fight fire, use alcohol foam, water, foam, CO₂, dry chemical. When heated to decomposition it emits highly toxic fumes of phosgene and Cl⁻.
