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. Can burn in a fire, releasing toxic vapors. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam.
