| Fire Fighting Measures | Back to Contents | 【Flash Point】
99 | 【Autoignition】
260 | 【Fire Fighting】
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing media: Use water spray to cool fire-exposed containers. Use foam, dry chemical, or carbon dioxide. Water may be ineffective. Use agent most appropriate to extinguish fire. | 【Fire Potential】
Combustible material: may burn but does not ignite readily. |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Clean up spills immediately, using the appropriate protective equipment. Provide ventilation. |
| Stability and Reactivity | Back to Contents | 【Disposal Code】
6 | 【Stability】
Stable under normal temperatures and pressures. | 【Incompatibilities】
Strong acids, strong bases, oxidizing agents, reducing agents, alkali metals. | 【Decomposition】
Carbon monoxide, oxides of sulfur, irritating and toxic fumes and gases, carbon dioxide, hydrogen sulfide. | 【Combustion Products】
During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. |
