See Section 9 for Flammability Properties 

Severe fire hazard. Vapor/air mixtures are explosive above flash point. The vapor is heavier than air. Vapors or gases may ignite at distant ignition sources and flash back. 

regular dry chemical, carbon dioxide, water, regular foam Large fires: Use regular foam or flood with fine water spray. 

Move container from fire area if it can be done without risk. Cool containers with water spray until well after the fire is out. Stay away from the ends of tanks. For fires in cargo or storage area: Cool containers with water from unmanned hose holder or monitor nozzles until well after fire is out. If this is impossible then take the following precautions: Keep unnecessary people away, isolate hazard area and deny entry. Let the fire burn. Withdraw immediately in case of rising sound from venting safety device or any discoloration of tanks due to fire. For tank, rail car or tank truck: Evacuation radius: 800 meters (1/2 mile). Do not attempt to extinguish fire unless flow of material can be stopped first. Flood with fine water spray. Do not scatter spilled material with high-pressure water streams. Cool containers with water spray until well after the fire is out. Apply water from a protected location or from a safe distance. Avoid inhalation of material or combustion by-products. Stay upwind and keep out of low areas. Water may be ineffective. 

Avoid heat, flames, sparks and other sources of ignition. Stop leak if possible without personal risk. Reduce vapors with water spray. Small spills: Absorb with sand or other non-combustible material. Collect spilled material in appropriate container for disposal. Large spills: Dike for later disposal. Remove sources of ignition. Keep unnecessary people away, isolate hazard area and deny entry. 

Store and handle in accordance with all current regulations and standards. Subject to storage regulations: U.S. OSHA 29 CFR 1910.106. Grounding and bonding required. Store in a cool, dry place. Store in a well-ventilated area. Avoid contact with air or light. Avoid heat, flames, sparks and other sources of ignition. Keep separated from incompatible substances. Keep separated from incompatible substances.

1,2-DICHLOROETHYLENE (ALL ISOMERS): Vapor exposure may cause mucous membrane irritation, nausea, vomiting, dizziness, weakness, tremor, and epigastric cramps Higher levels may cause central nervous system depression ranging from drowsiness to unconsciousness The cis- and trans- isomers together have been used as an anesthetic in man A human death has been reported from industrial exposure An 8 hour exposure to the trans- isomer at 200 ppm lowered the leukocyte count in rats; 1000 ppm caused a fall in the blood serum albumin, urea nitrogen, alkaline phosphatase activity, and the number of erythrocytes Narcosis was not produced at these levels 3000 ppm produced fibrous swelling of the cardiac muscle and hyperemia which persisted for 14 hours after exposure The cis- isomer did not anesthetize rats in 4 hours at 8000 ppm, but at 16,000 ppm they were anesthetized in 8 minutes and killed in 4 hours Reversible superficial corneal turbidity has been observed in some anesthetized dogs.

1,2-DICHLOROETHYLENE (ALL ISOMERS): Variations in data exist on the chronic toxicity of the cis- and trans- isomers Rats exposed to 200 ppm of the trans- isomer for 8 hours/day, 5 days/week for 16 weeks showed histological evidence of slight to severe fatty degeneration of liver lobules and kupffer cells, marked pulmonary hyperemia, alveolar septal distension and fibrous swelling of the cardiac muscle Similar exposures with rats, guinea pigs, rabbits and dogs exposed to 500 ppm or 1000 ppm 7 hours/day, 5 days/week for 6 months to a mixture of 60% cis- and 40% trans- isomers resulted in no adverse effects detected Cats and rabbits were repeatedly exposed to vapor concentrations of 0.16-0.19% in air The cis- isomer caused anorexia, decreased body weight and pathological changes in the lungs, liver, and kidneys The trans- isomer caused anorexia and some respiratory irritation, but no histopathological changes in organs.
