Hazards and Protection.
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
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.
Rubber gloves, self-contained breathing apparatus, coveralls or laboratory coat.
Wear positive pressure self-contained breathing apparatus (SCBA).
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.
Based on the behavior of 1,2-dichloropropane, explosions may be caused by contact with strong oxidizers or strong acids. An explosion hazard may occur if material enters confined spaces such as sewers.
Can react with some metals to form dangerous products Incompatible with strong oxidizing and reducing agents Incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.
Decomposes on heating producing HCl and phosgene.

Fire Extinguishing Agents: Foam, carbon dioxide, dry chemical.
Based on the 1,2-isomer, other dichloropropanes are probably quite flammable.
Flashback along vapor trail may occur.
Emits fumes of phosgene
Very high concentrations are depressant in animals.
At high concentrations the vapors are irritating to the respiratory tract.
CONJUNCTIVITIS - This chemical is moderately irritating to the eyes but is not expected to cause serious or permanent injury.
Seek medical assistance.
Remove to fresh air. If breathing has stopped, give artificial respiration.
Wash thoroughly with soap and water.
Flush with running water for 15 minutes.
