Fire Fighting Measures Back to Contents
【Flash Point】

87
【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 agent most appropriate to extinguish fire. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
【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
【Stability】

Stable under normal temperatures and pressures.
【Incompatibilities】

Strong oxidizing agents, strong bases.
【Decomposition】

Carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, hydrogen bromide.
