Chromic anhydride, toxicity

HAZARD RISK Dangerous fire hazard when exposed to heat or flame autooxidizes in air to form an unstable peroxide decomposition emits toxic fumes of Cl" reacts with oxidizing materials incompatible with chromic anhydride NFPA Code H 2 F 3 R 0. 

EXPLOSION and FIRE CONCERNS flammable liquid NFPA rating Health 2, Flammability 3, Reactivity 0 very dangerous fire hazard when exposed to heat or flame explosive in vapor form when exposed to heat or flame autooxidizes in air to form an unstable peroxide that eatalyzes exothermic polymerization of the monomer incompatible with liquid or gaseous fluorine incompatible or reacts violently with chromic anhydride when heated to decomposition, emits toxic fumes of CF use carbon dioxide, dry chemicals, water spray, or alcohol foam for firefighting purposes. 

ARSENOLITE or ARSENOUS ACID or ARSENOUS ACID ANHYDRIDE or ARSENOUS ANHYDRIDE (1327-53-3) AS2O3 Noncombustible solid.
