Phosphorus tribromide Safety Profile

Probably highly toxic. A corrosive irritant to the eyes, skin, and mucous membranes. Will react with water, steam, or acids to produce heat, toxic and corrosive fumes. Violent reaction or ignition with calcium hydroxide + sodium carbonate, phenylpropanol, sulfuric acid, oleum, fluorosulfuric acid, chlorosulfuric acid, 1,1,1-tris(hydroxymethyl)methane, water, potassium, sodium, RuO4. When heated to decomposition it emits very toxic fumes of Br and POx. See also PHOSPHIDES and BROMIDES.
