Extinguishing media: Substance is noncombustible; use agent most appropriate to extinguish surrounding fire.

Fire Potential

This material is nonflammable

Accidental Release Measures

Small spills/leaks

Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Provide ventilation.
