Exposure Effects

Effects may be delayed.

Fire Fighting Measures

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

This material is probably combustible.

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. Stable at room temperature in closed containers under normal storage and handling conditions.

Incompatibilities

Strong oxidizing agents, strong bases, acid chlorides, acid anhydrides.

Decomposition

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