Fires involving this compound should be controlled with a dry chemical, carbon dioxide or Halon extinguisher. A water spray may also be used.

Fire Potential

This material is probably combustible.

Accidental Release Measures

Small spills/leaks

If you spill this chemical, you should dampen the solid spill material with water, then transfer the dampened material to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all contaminated surfaces with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.
