Fire Fighting Measures

Flash Point

193

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, dry chemical, chemical foam, or alcohol-resistant foam.

Fire Potential

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.

Accidental Release Measures

Small spills/leaks

Vacuum or sweep up material and place into a suitable disposal container.

Stability and Reactivity

Stability

Stable under normal temperatures and pressures.

Incompatibilities

Strong oxidizing agents, acid anhydrides, chlorides.

Decomposition

Nitrogen oxides, carbon monoxide, carbon dioxide.

Combustion Products

Fire may produce irritating, corrosive and/or toxic gases.
