Safety Profile
Poison by skin contact and intraperitoneal routes. Mutation data reported. A corrosive irritant to skin, eyes, and mucous membranes. Moderately explosive when exposed to heat or by chemical reaction. In the presence of alkalies at elevated temperatures, free hydroxylamine is liberated and may decompose explosively. When heated to decomposition it emits toxic fumes of SOx and NOx. See also AMINES and SULFATES.
Toxicity
LD50 orally in Rabbit: 842 mg/kg LD50 dermal Rabbit 1500 - 2000 mg/kg
