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

May burn but does not ignite readily.

Accidental Release Measures

Small spills/leaks

Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Provide ventilation. Place under an inert atmosphere.

Stability and Reactivity

Stability

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

Incompatibilities

Strong oxidizing agents, strong acids, air.

Decomposition

Irritating and toxic fumes and gases, sulfur oxides (SOx), including sulfur oxide and sulfur dioxide, ammonia.

Combustion Products

During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion.
