Potential Health Effects
Inhalation: Causes irritation to the respiratory tract. Symptoms may include coughing, shortness of breath.
Ingestion: Causes irritation to the gastrointestinal tract. Symptoms may include nausea, vomiting and diarrhea. It presents little toxicity unless large amount are ingested, in which case, vomiting and diarrhea likely.
Eye Contact: Causes irritation, redness and pain.
Skin Contact: Causes irritation to skin. Symptoms include redness, itching and pain.
Environmental Effects High concentrations may affect organisms.
First Aid Measures
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious person. Get medical attention.
Immediately flush skin with plenty of soap and water. Remove contaminated clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes before reuse.
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.
Exposure Controls/Personal Protection
Airborne Exposure Limits: None established.
Ventilation System: In general, dilution ventilation is a satisfactory health hazard control for this substance. However, if conditions of use create discomfort to the worker, a local exhaust system should be considered.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator (NIOSH type N95 or better filters) may be worn. If oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres. Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.
Possible tumor promoter. May act as a mutagen. Toxic by inhalation. May be harmful if swallowed and in contact with skin. Eye, skin and respiratory irritant. Typical TLV 5 mg/m3.

PHYSICAL AND CHEMICAL PROPERTIES
Appearance:White Powder or Granular
Melting point: ca. 105 C (decomposes)
Density (g cm-3): 1.33
Autoignition temperature: 80 Deg. C.
Stability & reactivity
Danger! Highly reactive material.
Becomes unstable and spontaneously explosive at elevated temperatures.
Hazardous Decomposition Products:
Decomposes with formation of dense white smoke of benzoic acid, phenyl benzoate, terphenyls, biphenyls, benzene and carbon dioxide.
Will not occur.
A powerful oxidizer, Dibenzoyl peroxide is incompatible with many materials including organic and inorganic acids, alcohols, amines, metallic naphthenates, polymerization accelerators and easily oxidized materials. Heat, friction, organic matter, methyl methacrylate, N, N- dimethylaniline, lithium aluminum hydride, and carbon tetrachloride with ethylene have all caused fire or explosions when placed in contact with Dibenzoyl peroxide.
Conditions to Avoid:
Heat, flame, ignition sources, shock, friction, incompatibles.
Product Disposal:Depending on the type and extent of contamination, if any, special disposal methods may be required. Consult State environmental regulatory agencies for acceptable disposal procedures and locations.
