Fire Fighting

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion. Flammable solid. Extinguishing media: For large fires, use water spray, fog, or alcohol-resistant foam. Use water spray to cool fire-exposed containers. Water may be ineffective. For small fires, use dry chemical, sand, water spray, or foam.

Fire Potential

Flammable solid.

Accidental Release Measures

Small spills/leaks

Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal.

Stability and Reactivity

Stability

Stable under normal temperatures and pressures.

Incompatibilities

Strong oxidizers

Decomposition

Carbon monoxide, carbon dioxide.

Combustion Products

Fire may produce irritating and/or toxic gases.
