| Fire Fighting Measures | Back to Contents | 【Flash Point】
18 | 【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. Use water spray to keep fire-exposed containers cool. Containers may explode in the heat of a fire. Will react with water to form toxic and corrosive fumes. Extinguishing media: Substance is noncombustible; use agent most appropriate to extinguish surrounding fire. If water is the only media available, use in flooding amounts. DO NOT USE WATER! Do NOT get water inside containers. Cool containers with flooding quantities of water until well after fire is out. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam. | 【Fire Potential】
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. |
| 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. Do not get water on spilled substances or inside containers. |
| Stability and Reactivity | Back to Contents | 【Stability】
Stable under normal temperatures and pressures. | 【Incompatibilities】
Strong oxidants and reducing agents. Will react with water or steam to produce corrosive fumes. | 【Decomposition】
Carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, hydrogen fluoride. | 【Combustion Products】
Fire may produce irritating, corrosive and/or toxic gases. |
