Antimony, incompatibilities with

SAFETY PROFILE Moderately toxic by intraperitoneal route. See also ANTIMONY COMPOUNDS and SULFIDES. Flammable when exposed to heat or by chemical reaction with powerful oxidizers. Use water to fight fire. Moderately explosive when shocked or by spontaneous chemical reaction in contact with powerful oxidizers. When heated to decomposition or on contact with acid or acid fumes it emits highly toxic fumes of oxides of sulfur and antimony. Incompatible with water or steam to produce toxic and flammable vapors and with oxidizers, e.g., Ag(C103)2, HCIO3,... 

Finally, anions that are incompatible with oxidants will give rise to violent reactions with iodates. This goes for cyanides, thiocyanates and sulphides. In the last case, arsenic, antimony, copper and tin sulphides were the main ones cited. 

SAFETY PROFILE Confirmed carcinogen with experimental carcinogenic and neoplastigenic data. Poison by intravenous and subcutaneous routes. Moderately toxic by other routes. An experimental teratogen. Other experimental reproductive effects. Mutation data reported. See also ANTIMONY COMPOUNDS. When heated to decomposition it emits toxic Sb fumes. Incompatible with chlorinated rubber and heat of 216° and with BrFs. 

SAFETY PROFILE Poison by inhalation. Potentially explosive decomposition at 200°C. Flammable when exposed to heat or flame. Explosive reaction with ammonia + heat, chlorine, concentrated nitric acid, ozone. Incompatible with oxidants. The decomposition products are hydrogen and metallic antimony. When heated to decomposition it emits toxic fumes of Sb. Used as a fumigating agent. See also ANTIMONY COMPOUNDS and HYDRIDES. 

CHLORPYRIFOS (2921-88-2) CjHuCljNOjPS Noncombustible solid. Decomposed in water. Incompatible with strong acids, antimony(V) pentafluoride, lead diacetate, magnesiiun, silver nitrate. Hydrolyzed by acid, or alkali solutions. Attacks copper, copper alloys, including brass. On small fires, use dry chemical powder (such as Purple-K-Powder), foam, or CO2 extinguishers. 

DIMETHYLAMINO)-l-METHYL-3-OXO-l-PROPENYL DIMETHYL PHOSPHATE (141-66-2) May react violently with antimony(V) pentafluoride. Inconqjatible with nitrates. Corrosive to cast iron, mild (low carbon) steel, brass, and stainless steel 304. Slow hydrolysis in water. Deconqjoses in storage at tenqjeratures above 135°F/55°C. Incompatible with...
