Reported in EPA TSCA Inventory.

Moderately toxic by ingestion, inhalation, and skin contact. Mutation data reported. An eye and severe skin irritant. Combustible when exposed to heat, flames (sparks) or powerful oxidizers. To fight fire, use water (as a blanket), spray, mist, dry chemical. When heated to decomposition it emits toxic fumes of Cl⁻. See also CHLORINATED HYDROCARBONS, ALIPHATIC.

HazardClass 6.1(b)
PackingGroup III

1.General Description :May be absorbed through the skin. Vapors are heavier than air. Contact with vapors or liquid may cause burns or irritation.
2.Air & Water Reactions :Flammable.
3.Reactivity Profile: 1,2,3-Trichloropropene incompatible with strong oxidizing and reducing agents. Incompatible with many amines, nitrides, azo/diazo compounds, with alkali metals, and with epoxides. Reacts with bases. Produces toxic fumes when heated to decomposition. Avoid contact with iron, plastics, and aluminum.
4.Health Hazard TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
5.Fire Hazard :Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
