If breathing becomes difficult, oxygen may be given, preferably with a physician’s advice. Ifnot breathing, give artificial respiration. Get medical attention.SkinImmediately flush skin with soap and plenty of water. Remove contaminated clothing and equipment. Getmedical attention if symptoms occur. Wash clothing before reuse. Thoroughly clean or destroy contaminatedshoes.EyeImmediately flush eyes with plenty of running water. If victim is wearing contact lenses, remove them. Hold theeyelids apart during the flushing to ensure rinsing of the entire surface of the eye and lids with water. Getmedical attention if irritation persists.IngestionGet medical attention by calling a physician or a poison control center immediately. Do not induce vomitingunless directed to do so by medical personnel. If vomiting occurs, keep head below hips to reduce the risk ofaspiration. Never give anything by mouth to an unconscious person.Note to physicianPersons with pre-existing skin disease may be at an increased risk if exposed dermally to this material.Attending physician should treat exposed patients symptomatically.5. FIRE-FIGHTING MEASURESFlash pointnot determinedAutoignition temperaturenot determinedExplosion limitslower: N/Dupper: N/DExtinguishing mediaUse water fog, dry chemical, carbon dioxide, or foam extinguishing agents. Extinguish large fires with largeamounts of water spray, fog or foam from a safe/protected position.Fire fighting proceduresAs in any fire, prevent human exposure to fire, smoke, fumes or products of combustion. Evacuatenon-essential personnel from the fire area. Firefighters should wear full-face, self-contained breathingapparatus and impervious protective clothing. If possible, move containers from the fire area. If not leaking,keep fire exposed containers cool with a water fog or spray to prevent rupture due to excessive heat. Highpressure water may spread product from broken containers increasing contamination or fire hazard.Dike fire control water for later disposal. Do not allow contaminated water to enter waterways.Fire and explosion hazardsPeroxides and peroxide decomposition products are flammable and can ignite with explosive force if confined.Toxic and flammable vapors may be produced under combustion. Isolate from sources of ignition.This product may form flammable dust-air mixtures. Potential for dust explosion may exist. Depending uponconditions, dusts may be sensitive to static discharge.This product can produce flammable vapors which may travel to a source of ignition and flash back. Do not cut,grind, drill, or weld on or near the container (even empty) of this product because an explosion may result.Product code 11-076292 Date of last issue 10-01-2001 Page 2 of 7ics 409 Date of printing 01-23-2002 US-United States of America

ACCIDENTAL RELEASE MEASURESMethods for cleaning upRemove all sources of ignition from the spill area. All personnel involved in spill cleanup should follow goodindustrial hygiene practices. Wear protective clothing to prevent eye and skin contact. Use adequate ventilationand/or wear a NIOSH-approved acid gas respirator with dust, mist, and fume filter to minimize inhalationexposure. Stop source of spill if this is possible without being injured.Sweep up spilled solid material using non-sparking tools. Avoid creating dust. Place material in chemicalwaste container for disposal. Flush spill area with water.7. HANDLING AND STORAGEHandlingWear protective clothing when handling this product to avoid eye and skin contact. Wash thoroughly afterhandling.Electrically grounded tanks and containers should always be used as should non-sparking, electricallygrounded hand tools and appliances. Ground or bond to ground all vessels when transferring to prevent theaccumulation of static electricity. See National Electric Code. Emptied container may retain product residues.Follow all warnings and precautions even after container is emptied.StorageTo insure product quality, storage temperatures should not exceed 104 F (40 C). To insure against possibleexothermic self-accelerating decomposition, storage temperatures must not exceed 167 F (75 C). Thisemergency temperature is derived from the SADT (see Sect. 9). Keep containers tightly closed. Store awayfrom reducing agents (e.g. amines, acids, alkalis) and heavy metal compounds (e.g. driers metal soaps andaccelerators).Maximum storage temperature104.00 °F 40.00 °CGeneral commentsUse clean non-sparking equipment and tools when handling.Avoid generation of dust when handling this product. Keep containers tightly closed until ready for use. Washthoroughly after handling. Do not reuse container.Avoid contact with rust.8. EXPOSURE CONTROLS/PERSONAL PROTECTIONRespiratory protectionUse a NIOSH-approved organic vapor respirator with dust, mist and fume filters to reduce potential forinhalation exposure if use conditions generate vapor, mist or aerosol and adequate ventilation (e.g., outdoor orwell-ventilated area) is not available. Where exposure potential necessitates a higher level of protection, use aNIOSH-approved, positive-pressure/pressure-demand, air-supplied respirator.When using respirator cartridges or canisters, they must be changed frequently (following each use or at theend of the workshift) to assure breakthrough exposure does not occur.Product code 11-076292 Date of last issue 10-01-2001 Page 3 of 7ics 409 Date of printing 01-23-2002 US-United States of America

Indirect vented, dust-tight goggles should be worn whilehandling this material.Ventilation protectionSpecial ventilation is usually not required under normal use conditions. General plant ventilation should beadequate in most cases. If use conditions generate excesive airborne dust, use explosion-proof poweredventilation.Other informationSafety showers, with quick opening valves which stay open, and eye wash fountains, or other means of washingthe eyes with a gentle flow of cool to tepid tap water, should be readily available in all areas where this materialis handled or stored. Water should be supplied through insulated and heat-traced lines to prevent freezeups incold weather.Applicable exposure limitsOther than any exposure limits which may be displayed in Section 8, there are no other known exposure limitsapplicable to this product or its components.AgencyValue/Unit of measurementDibenzoyl peroxideOSHA PEL/TWA 5.000 mg/m³ACGIH TLV/TWA 5.000 mg/m³NIOSH REL/TWA 5.000 mg/m³PEL = Permissible Exposure LimitTLV = Threshold Limit ValueTWA = Time Weighted AverageSTEL = Short Term Exposure LimitCEIL = Ceiling Exposure LimitREL = Recommended Exposure LimitWEEL = Workplace Environmental Exposure LimitIDLH = Immediate Dangerous to Life and Health9.

STABILITY AND REACTIVITYStabilityThis product is stable at temperatures up to 167 F (75 C).IncompatibilitiesThis product is incompatible with strong acids, strong oxidizers, strong bases, metal salts, reducing agents andaccelerators.PolymerizationHazardous polymerization is not expected to occur under normal temperatures and pressures.DecompositionDecomposition products are carbon dioxide, carbon monoxide and biphenyl.Conditions to avoidThe SADT for this product is 176 F (80 C). The SADT (self-accelerating decomposition temperature) is anexperimentally derived temperature at which a typical package of the product will undergo self-acceleratingdecomposition. Decomposition can be expected to be hazardous and uncontrollable. Under no circumstancesshould this product be exposed to temperatures near or above the emergency temperature of 167 F (75 C).Such an exposure could initiate hazardous decomposition. Contact with incompatible materials such as acids,alkalis, heavy metals and reducing agents will also result in hazardous decomposition.11.
