Fire Fighting Measures
【Flash Point】155℃
【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 with caution and in flooding amounts. Oxidizer. Greatly increases the burning rate of combustible materials. Containers may explode in the heat of a fire. Extinguishing media: Use water only! Do NOT use carbon dioxide or dry chemical. Do NOT use alcohol foams. Cool containers with flooding quantities of water until well after fire is out.
【Fire Potential】These substances will accelerate burning when involved in a fire.

Accidental Release Measures
【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. Avoid generating dusty conditions. Provide ventilation. Do not get water inside containers.
