Hazards and Protection.
Storage
Keep away from sources of ignition. Store in a cool place in the original container and protect from sunlight. Flammables-area. Water free area.
Handling
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Do not allow water to get into the container because of violent reaction. Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Do not get in eyes, on skin, or on clothing. Do not ingest or inhale.
Protection
Wear appropriate clothing to prevent any reasonable probability of skin contact. Wear eye protection to prevent any possibility of eye contact.
Respirators
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
Small spills/leaks
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Clean up spills immediately, using the appropriate protective equipment. Remove all sources of ignition. Do not expose spill to water.
Stability
Has not been fully evaluated.
Incompatibilities
Halogenated agents, halogens, oxidizing agents, water, alcohols, organic acids, peroxides, amines, aqueous solutions, (may form explosive/incompatible mixtures with a wide range of substances).
Decomposition
Hydrogen chloride, chlorine.

Fire.
Flash Point,°C
35
Fire fighting
Use dry chemical, dry sand, or carbon dioxide. Do not use water on material itself. If large quantities of combustibles are involved, use water in flooding quantities as spray and fog. Use water spray to knock-down vapors. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
Fire potential
Flammable, moderate fire risk. Self-ignites in air. With a little ammonia, it forms a self-igniting product. Chlorosilanes certain strong corrosives may, on contact with organic matter or other chemicals, cause fire.
Hazards
Difficult to extinguish. Re-ignition may occur.
Combustion products
Irritating vapors of hydrogen chloride and phosgene may form.

Health.
Exposure effects
   Ingestion
Causes gastrointestinal tract burns.
   Inhalation
May cause severe irritation of the upper respiratory tract with pain, burns, and inflammation.
   Skin
Causes skin burns. May be absorbed through the skin in harmful amounts.
   Eyes
Causes eye burns.

First aid
 
   Ingestion
Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid immediately.
   Inhalation
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
   Skin
Get medical aid immediately. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
   Eyes
Flush with water 15 min.
