Flash Point

154

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 dry chemical, carbon dioxide, or appropriate foam.

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.

Stability and Reactivity

Incompatibilities

Oxidizing agents, acids, acid chlorides, acid anhydrides.

Stability

Stable under normal temperatures and pressures.

Decomposition

Carbon monoxide, carbon dioxide.
