AMMONIUM THIOSULFATE SOLUTION (60% OR LESS)

An odorless colorless liquid. (USCG, 1999)

• Strong Reducing Agent

No rapid reaction with air. No rapid reaction with water.

Special Hazards of Combustion Products: Toxic ammonia, hydrogen sulfide, and oxides of nitrogen and sulfur may form in fires. (USCG, 1999)

Contact with eyes may cause eye irritation with discomfort, tearing, or blurring of vision. Contact with skin may cause irritation with discomfort or rash. (USCG, 1999)

AMMONIUM THIOSULFATE SOLUTION is sensitive to heat. This chemical is incompatible with magnesium and aluminum powder. Mixtures with sodium chlorate can cause an exothermic reaction which can then decompose explosively. (NTP, 1992). Reacts with strong oxidizers such as chlorates, nitrates, and nitrites to release toxic ammonia, hydrogen sulfide, and sulfur trioxide gases. Will not polymerize. Ammonia, hydrogen sulfide, and oxides of nitrogen and oxides of sulfur may form in fires (USCG, 1999).
