Fire Potential

Not a fire or explosion hazard. Like most organic powders or crystals, under severe dusting conditions, this material may form explosive mixtures in air. Wear self-contained breathing apparatus and full protective equipment. Suitable extinguishing media: water spray, dry powder, foam, carbon dioxide (CO2). On small fires, if area is heavily exposed to fire and if conditions permit, let fire burn itself out since water may increase the contamination hazard.

Accidental Release Measures

Small spills/leaks

Shovel or sweep up. Never return to container for reuse. Scoop into bags or boxes with plastic or aluminium shovel.

Stability and Reactivity

Stability

Stable at normal temperatures and storage conditions.

Combustion Products
