Fire Fighting Measures
【Autoignition】527℃
【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. Runoff from fire control or dilution water may cause pollution. Extinguishing media: Use water spray to cool fire-exposed containers. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
【Fire Potential】Slightly. Requires preheating. Slight hazard.

Accidental Release Measures
【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
【Stability】Stable under normal temperatures and pressures.
【Incompatibilities】Strong oxidizing agents; strong bases.
【Decomposition】Carbon monoxide, carbon dioxide, acrid smoke and fumes.
【Combustion Products】Decomposes at 210 to carbon dioxide and pyrogallol, which can form irritating vapors.
