Safety Description:Poison by ingestion. Human systemic effects: tinnitus, pulse rate increase, blood pressure lowering. Experimental teratogenic and reproductive effects. Nitrites have been implicated in an increased incidence of cancer. Mutation data reported. Flammable when exposed to heat or flame. A powerful oxidizing material. Slight explosion hazard when exposed to heat. It will explode at 1000°F. Explosive reaction with potassium amide + heat, potassium cyanide or other cyanide salts + heat. Violent reaction or ignition with ammonium salts (e.g., ammonium sulfate), boron. Disproportionates on heating in the absence of air forming KNO₃ and K₂O and evolving N₂. Upon decomposition it emits toxic fumes of K₂O. See also NITRITES.
