Fire Fighting Measures

Flash Point

120

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. To extinguish fire use water spray, dry chemical, carbon dioxide, or appropriate foam.

Fire Potential

This chemical is combustible.

Accidental Release Measures

Small spills/leaks

Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Wash area with soap and water. Clean up spills immediately, using the appropriate protective equipment. Provide ventilation.

Stability and Reactivity

Incompatibilities

Strong oxidizing agents.

Stability

Substance undergoes color change upon exposure to air.

Decomposition

Carbon monoxide, carbon dioxide, acrid smoke and fumes.
