Hazards

Reactivity Alerts
none
Air & Water Reactions
Water soluble.
Fire Hazard
Special Hazards of Combustion Products: Toxic and irritating fumes of hydrogen iodide, iodine, and oxides of nitrogen may form in fire.

Behavior in Fire: Compound may sublime in fire and condense on cold surfaces. (USCG, 1999)
Health Hazard
Inhalation causes irritation of nose and throat. Contact with eyes causes irritation. (USCG, 1999)
Reactivity Profile
AMMONIUM IODIDE is light sensitive, becomes yellow or brown on exposure to air and light because of liberation of Iodine [Merck 11th ed. 1989]. Bromine trifluoride reacts explosively with ammonium iodide [Mellor 2 Supp. 1:165 1956].
