Not available.

Special hazards arising from the chemical:

Combustible in case of fire or high heat. Exposure to air or under light conditions can generate peroxides with potential explosion hazard. Combustion may produce carbon oxides.

Special fire fighting methods and special protective actions for fire-fighters:

Firefighters should wear self-contained breathing apparatus, and wear full-length firefighting gear, and cool the exposed container with water until all fire sources have been extinguished. Contain and dispose of fire-fighting water to prevent chemicals from entering the environment.

Methods and materials for containment and cleaning up:

Small leakage: absorb with sand, vermiculite or other inert materials. Large amount of leakage: constructing dikes or digging pits to contain. Use pump to transfer to tank truck or special collector, recycle or transport to waste disposal site for disposal.

Precautions to prevent the occurrence of secondary hazards:

Dispose of the collected spill immediately to avoid further leaks or sewers.
