Hazards and Protection.
Storage
Keep container closed when not in use. Corrosives area. Storage under a nitrogen blanket has been recommended. Store protected from moisture.
Handling
Keep container tightly closed. Do not get on skin or in eyes. Do not ingest or inhale. Use with adequate ventilation. Discard contaminated shoes.

Small spills/leaks
Clean up spills immediately, using the appropriate protective equipment. Absorb spill using an absorbent, non-combustible material such as earth, sand, or vermiculite. Provide ventilation.
Stability
Stable at normal temperatures in tightly closed containers under an inert atmosphere.
Incompatibilities
Strong oxidizing agents.
Decomposition
Chlorine, carbon monoxide, oxides of phosphorus, irritating and toxic fumes and gases, carbon dioxide, chloride fumes.

Fire.
Fire fighting
Small Fires: Use water. Do not use dry chemicals or foams. carbon dioxide or Halon may provide limited control. Large Fires: Flood fire area with water from a distance.
Fire potential
These substances will accelerate burning when involved in a fire.
Hazards
May explode from heat or contamination. May react explosively with hydrocarbons (fuels). May ignite combustibles.
Combustion products
Fire may produce irritating, corrosive and/or toxic gases.

Health.
