Safety and Handling
Safety Statements
S24/25
Safety
Poison by inhalation and ingestion. Severe irritant. A powerful oxidizing agent that is corrosive to the skin and mucous membranes. See also PEROXIDES, ORGANIC. Dangerous; shock or heat will cause detonation with evolution of toxic fumes; will react with water or steam to produce heat; can react vigorously with reducing materials. Flammable by spontaneous chemical reaction. To fight fire, use CO2 or dry chemical. When heated to decomposition it emits acrid smoke and fumes.
Skin, Eye, and Respiratory Irritations
A highly irritating material to skin, eyes and mucous membranes. /Acetyl benzoyl peroxide solution/
Cleanup Methods
Spills should be cleaned up promptly using non-sparking tools & an inert moist diluent such as vermiculite or sand. Sweepings may be placed in open containers or polyethylene bags and the area washed with water and detergent. Spilled, contaminated, waste or questionable peroxides should be destroyed. Incineration or burning is generally preferred. Burning may be done by spreading waste in a trench and igniting it from a distance. /Peroxides, organic/

Spilled, contaminated, waste or questionable peroxides should be destroyed. /Peroxides, Organic and Inorganic/
Dilute and drain into the sewer with abundant water. /Hydrogen peroxide/
Fire Fighting Procedures
In case of fire, water should be applied by the sprinkler system or by hose from a safe distance, preferably with a fog nozzle. Foam may be necessary instead if the peroxide is diluted in a low density flammable solvent. Portable extinguishers should not be used except for very small fires. Peroxides threatened by fire should be wetted from a safe distance for cooling. /Peroxides, Organic and Inorganic/
Fire Potential
Org peroxides are fuel rich compounds that generally ignite easily and burn vigorously. The oxygen oxygen bond is thermally unstable, decomposing exothermically at an increasing rate as temperature rises. Thermal instability varies widely. The 10-hr half-life temp of organic peroxides range from about 25 deg C to about 172 deg C. /Peroxides, organic/
Formulations/Preparations
The commercial product is mixed with a neutral drying powder and contains 50% acetyl benzoyl peroxide.
Marketed as a mixture with an equal part of an absorbent powder.
Reactivities and Incompatibilities
... WILL REACT WITH WATER & STEAM TO PRODUCE HEAT; CAN REACT VIGOROUSLY WITH REDUCING MATERIALS. /DRY FORM/
Other Preventative Measures
Emergency eyewash facilities should be provided. ... Should be washed promptly from the skin to prevent irritation. /Peroxides, org/
The safety of many organic peroxides is greatly improved by dispersing them in solvent or non-solvent diluents that absorb the heat of decomposition (eg water or plasticizer) or reduce shock sensitivity. ... Process equipment should be electrically bonded together and grounded. Non-sparking equipment should be used for handling. Peroxides must never be mixed directly with accelerators or other reactive materials, added to hot materials or placed in heated reaction vessels. Contamination should be carefully avoided by keeping the work area and equipment clean, handling peroxides in vessels of glass, polyethylene, teflon or stainless steel (304 or 316) to prevent contamination by corrosion, keeping containers closed, and disposing of excess peroxide promptly, never returning it to the original container. ... Smoking should be prohibited. Peroxides should not be stored in refrigerators containing food or drink. Laboratory reactions should be carried out behind a safety shield. /Organic peroxides/
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
Protective Equipment and Clothing
Persons handling organic peroxides should use safety glasses with side shields, goggles or face shields for eye protection. Emergency eyewash facilities should be provided. Gloves, aprons & other protective clothing as necessary should be used to prevent skin contact. Clothing & equipment that generate static electricity should be avoided. /Peroxides, organic/

Disposal Methods
SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
Rigid containers of uncertain age or condition should not be opened but carefully burned from a safe distance. /Peroxides, organic/
Incineration ... is generally preferred /method of destroying peroxides/. ... Most organic peroxides can also be hydrolyzed by adding them slowly with stirring to about ten times their weight of cold 10% sodium hydroxide soln. The reaction may require several hours. /Peroxides, organic/
