| Fire Fighting Measures | Back to Contents | 【Flash Point】
81-83 | 【Autoignition】
100 | 【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: Do NOT get water inside containers. For small fires, use dry chemical, carbon dioxide, or water spray. For large fires, use dry chemical, carbon dioxide, alcohol-resistant foam, or water spray. Cool containers with flooding quantities of water until well after fire is out. | 【Fire Potential】
Combustible material: may burn but does not ignite readily. |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Absorb spill using an absorbent, non-combustible material such as earth, sand, or vermiculite. Provide ventilation. Stop leak only if you can do so without risk. |
| Stability and Reactivity | Back to Contents | 【Disposal Code】
15 | 【Stability】
Stable under normal temperatures and pressures. | 【Incompatibilities】
Strong oxidizing agents. | 【Decomposition】
Carbon monoxide, carbon dioxide, tin/tin oxides. | 【Combustion Products】
