Safety Profile
A corrosive irritant to skin, eyes, and mucous membranes. Dangerous fire hazard when exposed to heat or flame; can react vigorously with oxidizing materials. Reacts with water or steam to produce toxic and corrosive fumes. Exothermic reaction with diisopropyl ether produces much gas. The reaction may be dangerous if confined. To fight fire, use CO2, dry chemical; do not use water. When heated to decomposition it emits highly toxic fumes of Cl−.
