| Fire Fighting Measures | Back to Contents | 【Flash Point】
90 | 【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 appropriate foam. | 【Fire Potential】
Flammable/combustible material. May be ignited by friction, heat, sparks or flames. |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
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 | Back to Contents | 【Disposal Code】
3 | 【Incompatibilities】
Oxidizing agents, strong bases. | 【Stability】
Stable under normal temperatures and pressures. | 【Decomposition】
Carbon monoxide, oxides of sulfur, carbon dioxide, hydrogen sulfide. | 【Combustion Products】
Fire may produce irritating and/or toxic gases. |
