Safety Profile
Poison by ingestion and inhalation. A fuming, corrosive liquid very irritating to shin, eyes, and mucous membranes. It decomposes on contact with water to form the highly irritating hydrogen chloride, thiosulfuric acid, and sulfur. Its toxic effects are irritating to the upper respiratory tract, although the results of intoxication are usually transitory in nature. However, if hydrolysis is not complete in the upper respiratory tract, injury to the broncholes and alveoli can result. A fire hazard when in contact with organic matter, P203, Na2O2, water, Cr(OCl)2. Combustible when exposed to heat or flame. Will react with water or steam to produce heat and toxic and corrosive fumes. Can react with oxidizing materials. To fight fire, use CO2, dry chemical. When heated to decomposition it emits highly toxic fumes of Cland SOX.
