Safety | A poison by ingestion. Hydrolysis yields KOH which is toxic and irritating. When heated it explodes weakly releasing nitrogen. Explosive reaction with sulfur dioxide at 120°C. Reacts with carbon disulfide to form an explosive product. Reacts violently with manganese dioxide when warmed. When heated to decomposition it emits very toxic fumes of NOx and K2O.

Potassium Azide (CAS NO.20762-60-1) is a colorless crystals. It is a salt of hydrazoic acid, and crystallizes in a tetragonal structure. Upon heating or irradiation with ultraviolet light, it decomposes into potassium metal and nitrogen gas. Unlike heavy-metal azides, it is not sensitive to shock, but may explode if heated rapidly.
