Fire Fighting Measures
【Autoignition】531
【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. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam.
Accidental Release Measures
【Small spills/leaks】Wash area with soap and water. Clean up spills immediately, using the appropriate protective equipment. Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Avoid generating dusty conditions. Provide ventilation.
Stability and Reactivity
【Incompatibilities】Acids; acid chlorides; acid anhydrides; oxidizing agents.
【Stability】Stable under normal temperatures and pressures. May discolor on exposure to light.
【Decomposition】Nitrogen oxides, carbon monoxide, oxides of sulfur, carbon dioxide.
