| Fire Fighting Measures | Back to Contents | 【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. | 【Fire Potential】
This material is probably combustible. |
| 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 | 【Stability】
Stable under normal shipping and handling conditions. However, may decompose if heated. | 【Incompatibilities】
Strong oxidizing agents, strong reducing agents, alkalis, dichromates, alkali iodides. | 【Decomposition】
Nitrogen oxides, carbon monoxide, carbon dioxide, sulfur oxides (SOx), including sulfur oxide and sulfur dioxide. | 【Combustion Products】
