Hazards and Protection.
Storage
Store in a clean, cool, dry and well-ventililated location. Keep containers tightly closed.
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 chemical protective clothing.
Respirators
Wear positive pressure self-contained breathing apparatus.
Small spills/leaks
Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors.
Stability
Stable at normal temperatures and pressures.
Incompatibilities
Can react violently with strong reducing agents such as the very active metals and the active metals.
Decomposition
Oxides of carbon, hydrogen chloride, hydrogen fluoride.

Fire.
Fire fighting
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Do not use water on material itself. Use water spray to knock-down vapors.
Fire potential
May burn but does not ignite readily.
Hazards
