4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Substance is non-combustible. Stable at room temperature in closed containers under normal storage and handling conditions. Avoid excess heat. Incompatible with acids, alkalis and their associated carbonates. Substance reacts with lead and silver salts to form a fulminating compound. Substance reacts with ammonium compounds, bromine pentafluoride, bromine trifluoride, hydrogen cyanide, iodine heptafluoride, nitrates and potassium chlorate. Hazardous decomposition products include ammonia and hydrochloric acid fumes. Hazardous polymerisation has not been reported. At fire temperatures ammonium chloride begins to corrode metals and may dissociate into ammonia and hydrogen chloride. Mixtures of about 16% to 25% (by volume) ammonia gas in air are flammable.
Extinguishing Media
Use any means suitable for extinguishing surrounding fire. Water spray may be used to keep fire exposed containers cool. 5 OTHER INFORMATION
