Important Benzoyl Peroxide (BPO) Information
BPO contains highly reactive (unstable) chemicals that produce the curing reaction of methacrylic resins. The highly
reactive property of BPO also produces hazards that require great care and caution in the handling, processing, stor-
age, transportation and disposal of BPO.
WARNING
BURN HAZARD
Equipment surfaces and fluid that’s heated can become very hot during operation. To avoid severe burns:
• Do not touch hot fluid or equipment.
PERSONAL PROTECTIVE EQUIPMENT
Wear appropriate protective equipment when in the work area to help prevent serious injury, including eye
injury, hearing loss, inhalation of toxic fumes, and burns. This protective equipment includes but is not lim-
ited to:
•
Protective eyewear, and hearing protection.
•
Respirators, protective clothing, and gloves as recommended by the fluid and solvent manufacturer.
CALIFORNIA PROPOSITION 65
This product contains a chemical known to the State of California to cause cancer, birth defects or
other reproductive harm. Wash hands after handling.
BPO is flammable and potentially explosive when reacting to contamination by other materials or when
exposed to heat or heat build-up from contamination reactions. A contamination reaction can cause BPO to
reach its Self-Accelerating Decomposition Temperature (SADT). Reaction may start slowly, taking from sec-
onds to days, gradually building up heat. This can produce an explosion. To help prevent fire and explosion:
•
Read and understand the BPO manufacturer’s warnings and Safety Data Sheet (SDS) to know specific
hazards and precautions related to BPO.
•
Prevent contamination of BPO with other materials (even small amounts), including but not limited to
diluents, polyester overspray, sanding dust, polymerization accelerators and promoters, and non-stainless
metals. Keep work area clean and free of waste.
•
Never return BPO to the original container.
•
Remove spills promptly so no residues remain.
•
Keep BPO away from heat, sparks and open flames.
•
Never dilute BPO with acetone or any solvent. This can produce an extremely shock-sensitive compound
that can explode.
•
Use only genuine manufacturer’s parts in the catalyst system (hoses, fittings, etc.). A reaction may result
between substituted parts and BPO.
•
Store BPO in the original containers in a cool, dry and well-ventilated area away from direct sunlight and
away from other chemicals in accordance with BPO manufacturer’s recommendations.
•
Do not store BPO for an extended period of time.
•
To prevent contact with BPO, wear appropriate personal protective equipment, including chemically imper-
meable gloves, boots, aprons and goggles.
