Sweep up spilled material and place in a suitable containers for later disposal. Ventilate area and wash spill site after material pickup is complete.
Disposal
Waste benzoyl poeroxide may be destroyed safely by treatment with about ten times its weight of 10% sodium hydroxide solution. The peroxide should be added gradually in small portions with sufficient agitation to prevent setting or lump formation. Dispose according to all local, state and federal regulations.
4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Evacuate unnecessary personnel. Non-burning material should be relocated to a safe area as soon as possible. Material is dangerous when exposed to heat and flames. Dehydrated material is explosive when heated in confined spaces. Benzoyl peroxide burns with intense heat and is difficult to extinguish. Carbon dioxide and carbon monoxide released on decomposition.
Extinguishing Media
Fire-fighters should wear full protective clothing including self-contained breathing apparatus. Water most effective, also water fog, carbon dioxide and dry chemical may be used a extinguishing media. 5 OTHER INFORMATION
Other Information
Do not add to hot materials. Do not grind or subject to friction heat. Prevent contamination with readily oxidizable materials and polymerization accelerators.
