Hazard Toxic by ingestion, inhalation, and skin absorption. TLV: 10 ppm. NIOSH has recommended 1 ppm. Flammable, dangerous fire risk, explosive limits in air 4.0 to 20%.
Risk R10
Safety Confirmed carcinogen. Poison by ingestion, intravenous, and subcutaneous routes. Moderately toxic by inhalation. An experimental teratogen. Experimental reproductive effects. Human mutation data reported. Human exposure has caused dermatitis, conjunctivitis, corneal necrosis, anemia, temporary loss of hair, nervousness, and irritability. Exposure to the vapor can cause respiratory tract irritation leading to asphyxia. Other effects are central nervous system depression, drop in blood pressure, severe degenerative changes in the liver, kidneys, lungs, and other vital organs. A very dangerous fire hazard when exposed to heat or flame. Explosive in the form of vapor when exposed to heat or flame. To fight fire, use alcohol foam. Auto-oxidizes in air to form an unstable peroxide that catalyzes exothermic polymerization of the monomer. Incompatible with liquid or gaseous fluorine. When heated to decomposition it emits toxic fumes of Cl−. See also CHLORINATED HYDROCARBONS, ALIPHATIC.Analytical Methods: For occupational chemical analysis use NIOSH: Chloroprene, 1002.
