Safety Profile
Moderately toxic by ingestion, intraperitoneal, and intravenous routes. Experimental reproductive effects. Mutation data reported. Causes cholinesterase inhibition, but to a lesser extent than parathion. May be expected to cause nerve injury similar to that of other phosphate esters. Combustible when exposed to heat or flame. Can react vigorously with oxidizing materials. To fight fire, use CO2, dry chemical, alcohol foam. When heated to decomposition it emits toxic fumes of POx. See also PARATHION.
