BrandgefahrenSpecial Hazards of Combustion Products: Toxic and irritating ammonia and formic acid gases may form in fire. (USCG, 1999)
GesundheitsgefahrenInhalation causes irritation of nose and throat. Ingestion irritates mouth and stomach. Contact with eyes or skin causes irritation. (USCG, 1999)
GefahrenübersichtA skin and mucous membrane irritant[HSDB]
Reaktive GruppeSalts, Acidic
Reactivity ProfileAcidic salts, such as AMMONIUM FORMATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
Air and Water ReactionsWater soluble.
