Safety Description:Moderately toxic by ingestion. Not as toxic as the simple cyanides. Mutation data reported. Explosive reaction with ammonia, chromium trioxide (above 196°C), sodium nitrite + heat. Violent reaction with Cu(NO3)2. Mixtures with chromium trioxide + silver grains ignite with friction. When heated to decomposition or on contact with acid or acid fumes it emits highly toxic fumes of K2O and CN−. Used as a fixative in photography, as a metal cleaner, and for glass coatings.
