General Description
A colorless crystalline solid or a white powder with a strong odor of ammonia. Noncombustible. The primary hazard is the threat to the environment. Immediate steps should be taken to limit spread to the environment. Used to make other ammonium compounds, in pharmaceuticals, in food processing.

Hazards

Reactivity Alerts
Air & Water Reactions
Water soluble.
Fire Hazard
Special Hazards of Combustion Products: Toxic ammonia gas will form in fires.

Behavior in Fire: Decomposes, but reaction is not explosive. Ammonia gas is formed. (USCG, 1999)
Health Hazard
Inhalation causes irritation of nose and throat. Ingestion may cause gastric irritation. Contact with eyes or skin causes irritation. (USCG, 1999)
Reactivity Profile
AMMONIUM CARBONATE decomposes when heated to give gaseous ammonia and gaseous carbon dioxide. Reaction is non-explosive. Causes decomposition of sodium hypochlorite within a few seconds [Mellor 2 Supp. 1:550 1956].
Belongs to the Following Reactive Group(s)
