General Description
Ammonium sulfite is a colorless crystalline solid. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. It is used in the manufacture of other chemicals, in medicine, and photography.

The Hazard fields include special hazard alerts, air and water reactions, fire hazards, health hazards, a reactivity profile, and details about reactive groups assignments and potentially incompatible absorbents. The information in CAMEO Chemicals comes from a variety of data sources.
Reactivity Alerts
none
Air & Water Reactions
Soluble in water.
Fire Hazard
Special Hazards of Combustion Products: Toxic sulfur dioxide and oxides of nitrogen may form in fires. (USCG, 1999)
Health Hazard
Inhalation of dust causes irritation of nose and throat. Ingestion causes irritation of mouth and stomach. Dust irritates eyes. (USCG, 1999)
Reactivity Profile
AMMONIUM SULFITE is a reducing agent. Emits toxic sulfur dioxide and oxides of nitrogen when heated to decomposition (USCG, 1999).
