Consensus Reports
NTP Carcinogenesis Studies (inhalation); Clear Evidence: rat; No Evidence: mouse NTPTR* National Toxicology Program Technical Report Series. (Research Triangle Park, NC 27709) No. NTP-TR-329 (1988). . Community Right-To-Know List. EPA Genetic Toxicology Program. Reported in EPA TSCA Inventory.
Safety Profile
Confirmed carcinogen with experimental carcinogenic data. Moderately toxic by ingestion and skin contact. Mildly toxic by inhalation. Experimental reproductive effects. Mutation data reported. Dangerous fire hazard when exposed to heat, flame, or powerful oxidizers. To fight fire, use dry chemical, water spray, mist or fog, alcohol foam. When heated to decomposition it emits acrid smoke and fumes.
