Poison by inhalation and ingestion. Severe irritant. A powerful oxidizing agent that is corrosive to the skin and mucous membranes. See also PEROXIDES, ORGANIC. Dangerous; shock or heat will cause detonation with evolution of toxic fumes; will react with WATER or steam to produce heat; can react vigorously with reducing materials. Flammable by spontaneous chemical reaction. To fight fire, use CO₂ or dry chemical. When heated to decomposition it emits acrid smoke and fumes.
