Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Dusts at sufficient concentrations can form explosive mixtures with air. Extinguishing media: For small fires, use water spray, dry chemical, carbon dioxide or chemical foam.
Fire Potential
This material is probably combustible.

Accidental Release Measures

Small spills/leaks
Wear a self contained breathing apparatus and appropriate Personal protection. (See Exposure Controls, Personal Protection section). Sweep up, then place into a suitable container for disposal.
