Consensus Reports

Safety Profile
Moderately toxic by ingestion. Mildly toxic by inhalation. Human systemic effects by inhalation: sleep, hallucinations, and distorted perceptions. Experimental reproductive effects. A skin and eye irritant. Mutation data reported. Exposure to high vapor concentration can cause nausea, vomiting, weakness, tremor, and cramps. Recovery is usually prompt following removal from exposure. Dermatitis may result from defatting action on skin. Dangerous fire hazard when exposed to heat, flame, or oxidizers. Moderate explosion hazard in the form of vapor when exposed to flame. Violent reaction with difluoromethylene dihypofluorite. Forms shock-sensitive explosive mixtures with dinitrogen tetraoxide. Reaction with solid caustic alkalies or their concentrated solutions produces chloracetylene gas that ignites spontaneously in air. Reacts violently with N2O4, KOH, Na, NaOH. Moderate explosion hazard in the form of vapor when exposed to flame. Can react vigorously with oxidizing materials. To fight fire, use water spray, foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of Cl−. See also CHLORIDES; CHLORINATED HYDROCARBONS, ALIPHATIC; and ACETYLENE COMPOUNDS and ALKYNES.

Specification
The chemical synonyms of trans-1,2-Dichloroethylene (CAS NO.156-60-5) are (E)-1,2-Dichloroethene ; (E)-1,2-Dichloroethylene ; 4-01-00-00709 (Beilstein Handbook Reference) ; AI3-28786 ; BRN 1420761 ; CCRIS 2505 ; Ethylene, 1,2-dichloro-, trans- ; HCC 1130t ; HSDB 6361 ; NSC 60512 ; R 1130t ; RCRA waste number U079 ; trans-Acetylene dichloride ; trans-Dichloroethylene . It is highly flammable. Oxidizes in air to form unstable peroxides that may explode spontaneously. Avoid contact with copper and copper alloys. trans-1,2-Dichloroethylene reacts with alkalis, difluoromethylene, dihypofluorite, and nitrogen tetraoxide. Contact with solid alkalis or their concentrated solutions will cause formation of chloroacetylene, which ignites in air. Corrosive to metals unless an inhibitor has been added. Oxidation in the presence of concentrated sulfuric acid or a free radical initiator gives chloroacetyl chloride via epoxide intermediates. It is incompatible with organic peroxides.
