Hazards and Protection.
Storage
Follow recommendations for 1,3-dichloropropene. Do not place or store 1,3-dichloropropene in containers made of aluminum, magnesium, or alloys of these metals. Handle as a flammable liquid. Store at in tightly closed containers in a cool place.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protection
Wear appropriate clothing to prevent any reasonable probability of skin contact. Wear eye protection to prevent any possibility of eye contact.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Make no contact with the spilled material. Fully encapsulating, vapor protective clothing should be worn for spills and leaks with no fire. ELIMINATE all ignition sources and ground all equipment. Stop leak if you can do it without risk. A vapor suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Use clean non-sparking tools to collect absorbed material.
Stability
Container may explode in heat of fire and runoff to sewer may be a fire or explosion hazard. Dichloropropenes are a vapor explosion hazard indoors, outdoors, or in sewers.
Incompatibilities
Oxidizing agents, aluminum, halogens, metal salts.
Decomposition
Oxides of carbon, hydrogen chloride.

Fire.
Flash Point,°C
0.5
Fire fighting
Use powders, halons, carbon dioxide. Keep tanks and drums cool by spraying water. NFPA recommendations for 1,3-dichloropropene-use water spray, dry chemical, foam, or carbon dioxide. Water spray may not extinguish the fire but can disperse vapors, protect workers, or flush spills. DOT recommendations for dichloropropene-for small fires, dry chemicals, carbon dioxide, or foam. For large fires, use water spray, fog, or foam. Move container from fire area if it can be done without risk. Keep water out of containers. Cool containers exposed to a fire with water from the side until well after fire is out, and withdraw immediately if a rising sound is heard from the venting safety device or if the tank discolors.
Fire potential
Expect that all dichloropropenes are as flammable as 1,3-dichloropropenes. 1,3-Dichloropropene is quite flammable. Flashback may occur along vapor trail. Vapor in an enclosed area may ignite.
Hazards
Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers.
Combustion products
Fire will produce irritating, corrosive and/or toxic gases.

Health.
Exposure effects
   Ingestion
May cause toxic effects.
   Inhalation
Vapors may cause dizziness or suffocation. May cause toxic effects.
   Skin
Contact with substance may cause severe burns.
   Eyes
See Skin.

First aid
 
   Ingestion
Seek medical assistance.
   Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
   Skin
Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush with running water for at least 20 minutes. Wash skin with soap and water.
   Eyes
In case of contact with substance, immediately flush with running water for at least 20 minutes.
