products
Fire extinguishing
Use flooding quantities of water. Wear adequate personal protection to prevent contact with material or its combustion procedures
products. Self contained breathing apparatus with a full facepiece operated in a pressure demand or other positivepressure mode. Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool containingvessels with flooding quantities of water until well after fire is out.
Fire and Explosion
May explode when heated. Extremely flammable solid. Extreme risk of explosion by shock, friction, fire or other sources of ignition. Container explosion may occur under fire conditions or when heated. Powerful oxidizing agent;may ignite oxidizable materials. Contact with other material may cause fire and/or explosion. Spontaneous heatingmay occur on contact with combustible materials (ex., paper, rags). This material in powder form is capable ofcreating a dust explosion. Sensitive to static discharge. The product is sensitive to impact. Emits toxic fumesunder fire conditions.
Section V. Toxicological Properties
Routes of entry
Ingestion and inhalation. Eye contact. Skin contact. Skin absorption.
Effects of Acute
Harmful by inhalation, in contact with skin and if swallowed. Target organs: eyes, skin, respiratory system. 1500 Exposure
mg/m3 (BENZOYL PEROXIDE) is immediately dangerous to life or health.
Causes severe irritation. May cause severe burns and loss of vision. May cause permanent damage. The amount oftissue damage depends on lenght of contact.
Causes severe irritation. Prolonged exposure may result in skin burns and dermatitis. May cause sensitization byskin contact. Readily absorbed through skin.
Inhalation
Material is irritating to mucous membranes and upper respiratory tract. May cause asthmatic effects andvasodilation.
Ingestion
Toxic. Causes gastrointestinal irritation. May cause headache, nausea, vomiting, abdominal pain, depression anddeath.
Section V. Toxicological Properties
BENZOYL PEROXIDE
Effects of Chronic
May cause sensitization by inhalation and skin contact. May cause testicular atrophy. Possible tumor promoter.
Overexposure
Carcinogenic effects: Not available. Mutagenic effects: Not available. Teratogenic effects: Not available. Toxicity of theproduct to the reproductive system: Not available. To the best of our knowledge, the chemical, physical, and toxicity ofthis substance has not been fully investigated.
Section VI. First Aid Measures
Eye contact
IMMEDIATELY flush eyes with copious quantities of water for at least 15 minutes holding lids apart to ensure flushingof the entire surface. Seek immediate medical attention.
Skin contact
Immediately flush skin with plenty of water and soap for at least 15 minutes while removing contaminated clothingand shoes. Seek immediate medical attention. Wash contaminated clothing before reusing.
Inhalation
Remove patient to fresh air. Administer approved oxygen supply if breathing is difficult. Administer artificial respirationor CPR if breathing has ceased. Seek immediate medical attention.
Ingestion
If conscious, wash out mouth with water. Seek immediate medical attention. Never give anything by mouth to anunconscious or convulsing person.
Section VII. Reactivity Data

case of spill and leak
Spill and leak
Evacuate the area. Eliminate all sources of ignition. Keep substance damp using water spray. Place in a suitablecontainer and mark for disposal. Avoid raising dust. Use non-sparking tools. Ventilate area and wash spill site aftermaterial pick up is complete. DO NOT empty into drains. DO NOT touch spilled material. Avoid contact with acombustible material (wood, paper, oil, clothing.). Spills of benzoyl peroxide must be promptly removed.
Waste disposal
Dispose of waste material at an approved (hazardous) waste treatment/ disposal facility in accordance with applicablelocal, provincial and federal regulations. Consult your local or regional authorities.
Storage and Handling
Use only polyethylene tools and containers. Do not grind or subject to friction or shock. Store in a cool place away from heated areas,sparks, and flame. Store in a well ventilated area. Store away from incompatible materials. Do not add any other material to the container.
Do not wash down the drain. Avoid shock and friction. Do not breathe dust. Keep away from direct sunlight or strong incandescent light.
Keep container tightly closed. Manipulate under an adequate fume hood. Avoid raising dust. Use explosion proof equipment. Usenon-sparking tools. Empty containers may contain a hazardous residue. Handle and open container with care. Minimize dust generationand exposure - use dust mask or appropriate protection. Take off immediately all contaminated clothing. This product must bemanipulated by qualified personnel. Do not get in eyes, on skin, or on clothing. Wash well after use. In accordance with good storage andhandling practices. Do not allow smoking and food consumption while handling. Do not use pressure to dispense. Since the product isunstable, avoid sudden shocks like dropping or rolling. Do not drop, roll or skid container. If you feel unwell, seek medical advice (showthe label when possible). May catch fire in contact with combustible materials. May react if roughly manipulated. Keep away fromcombustible material (wood, paper, oil, clothing.). Refrigerate.
Section IX. Protective Measures
Splash goggles. Impervious rubber gloves, rubber apron, coveralls, and/or other resistant protective clothing. Sufficient to protect skin. Have Protective clothing
available and use as appropriate: face shields, rubber suits, and boots. A OSHA/MSHA jointly approved respirator is advised in the absence ofproper environmental controls. If more than TLV, do not breathe vapor. Wear self-contained breathing apparatus. Do not wear contact lenses.
Make eye bath and emergency shower available. Ensure that eyewash station and safety shower is proximal to the work-station location.
Engineering controls
Use in a chemical fume hood to keep airborne levels below recommended exposure limits. Use explosion-proofventilation equipment. Do not use in unventilated spaces.
Section X. Other Information
Special Precautions or Powerful oxidizing agent; may ignite oxidizable materials. Explosive/ flammable solid!
