Reported in EPA TSCA Inventory.
Poison by parenteral and intraperitoneal routes. Mutation data reported. An irritant and sensitizer. Many nitroso compounds are carcinogens. A very dangerous fire and explosion hazard. When exposed to heat or flame, it burns explosively. Contamination by acid or alkali may cause ignition. Can heat spontaneously and cause fire. When heated to decomposition it emits toxic fumes of NOx.
