Section 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Strong oxidizer. Contact with combustible materials may cause a fire. Will burn if involved in a fire. This material poses an explosion hazard when dry. Flammable solid. This material is an explosion hazard when exposed to heat, mechanical shock, friction or when agitated.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Use water spray, dry chemical, carbon dioxide, or chemical foam. Do NOT use halogenated agents.

Section 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Remove all sources of ignition. Provide ventilation. Do not use combustible materials such as paper towels to clean up spill. Use only non-sparking tools and equipment. In the event of spillage, spilled material should be mixed with water-wetted vermiculite, swept up, and placed in a container for immediate disposal.

Section 7 - HANDLING and STORAGE
Handling:
Wash thoroughly after handling. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Avoid contact with heat, sparks and flame.
Avoid ingestion and inhalation. Use caution when opening. Can explode without warning when caps of old containers are unscrewed.
Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
Storage:
Keep away from heat and flame. Do not store in direct sunlight.
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep refrigerated. (Store below 4C/39F.)

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
Engineering Controls:
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.
Personal Protective Equipment Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHAs eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin exposure.
Respirators:
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.

Section 10 - STABILITY AND REACTIVITY
Chemical Stability:
Stable under normal temperatures and pressures. Do not allow to dry.
In its dry form, Benzoly Peroxide is highly flammable and explosive, sensitive to friction, shock and heat, and must be handled with extreme caution.
Conditions to Avoid:
Mechanical shock, ignition sources, excess heat, combustible materials, reducing agents, temperatures above 100C, organic matter.
Incompatibilities with Other Materials:
Reducing agents, strong acids, bases, amines, metals, accelerators, methyl methacrylate, carbon tetrachloride and ethylene, organic matter, N,N - dimethylaniline and lithium aluminum hydride. Benzoyl peroxide is self-reactive chemical which can even explode without warning when the caps of old jars are unscrewed. It is extremely important to keep it pure, contaminants can lead to hazardous, unexpected explosions.
Hazardous Decomposition Products:
Carbon monoxide, carbon dioxide, benzene.
Hazardous Polymerization: Has not been reported.
