CONTACT WITH EYES OR SKIN: irritates eyes. Prolonged contact may irritate skin. (USCG, 1999)
Excerpt from ERG Guide 145 [Organic Peroxides (Heat and Contamination Sensitive)]: Fire may produce irritating, corrosive and/or toxic gases. Ingestion or contact (skin, eyes) with substance may cause severe injury or burns. Runoff from fire control or dilution water may cause pollution. (ERG, 2016)
Excerpt from ERG Guide 146 [Organic Peroxides (Heat, Contamination and Friction Sensitive)]: Fire may produce irritating, corrosive and/or toxic gases. Ingestion or contact (skin, eyes) with substance may cause severe injury or burns. Runoff from fire control or dilution water may cause pollution. (ERG, 2016)4.3 Indication of immediate medical attention and special treatment needed, if necessary
For immediate first aid: Ensure that adequate decontamination has been carried out. If victim is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep victim quiet and maintain normal body temperature. Obtain medical attention. /Organic peroxides/5.Fire-fighting measures 5.1 Extinguishing media Suitable extinguishing media

VERY STABLE /SRP: SHELF LIFE/ @ ORDINARY TEMP (25 DEG C)10.3 Possibility of hazardous reactions
Unstable to heat; decomposes with evolving oxygen, resulting in advancing fire. Sensitive to impact and friction.BENZOYL PEROXIDE is a white, odorless powder, moderately toxic. It is most dangerous when it contains less then 1% water. A moisture content of 3% allowed slow burning only, and at 5% ignition did not occur [McCloskey, C. M. et al., Chem. Abs., 1967, 66, 12613c]. Mixed with a large surplus of water (30% or more), it is relatively safe. In dry form, it is a very dangerous material. It will explode spontaneously when heated above melting point (103° C). An explosion which occurred when a screw-capped bottle of the peroxide was opened has been attributed to friction, which initiated a mixture of peroxide and organic dust in the cap threads [Lappin, G. R., Chem. Eng. News, 1948, 26, p.3518]. A violent explosion occurred during purification of the peroxide by Soxhlet extraction with hot chloroform [Anon., Sichere Chemiearb., 1976, 28, p. 49]. It is a powerful oxidizer, which ignites readily and burns rapidly. In contact with reducing agents, it may ignite by spontaneous chemical reaction. It must be kept in a cool place, in isolation and out of the sunlight or sources of heat. Also, avoid shock or friction. It reacts violently with inorganic or organic acids, alcohols, amines, metallic naphthenates and polymerization accelerators (e.g., N,N-dimethylaniline). Explosive or violent reaction upon contact with dimethyl sulfide, lithium aluminum hydride or aniline [Bretherick, 5th ed., 1995, p. 1140]. Mixture with carbon tetrachloride and ethylene explodes when exposed to heat [Bolt, R. O. et al., Chem. Eng. News, 1947, 25, p. 1866]. Ignition occurred upon contact with methyl methacrylate [MCA Case History No. 996], polymerization of vinyl acetate in ethyl acetate accelerated out of control leading to ignition and explosion [Vervalin, 1973, p. 81]. At 50° C a mixture of dibenzoyl peroxide and charcoal reacts violently producing dense white smoke of benzoic acid, benzene, phenyls and carbon dioxide [Leleu, Cahiers, 1980, 99, p. 279].10.4 Conditions to avoid

- Toxicity to fish: no data available
- Toxicity to daphnia and other aquatic invertebrates: no data available
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
In the Japanese MITI test, benzoyl peroxide (present at 100 ppm) reached 84 percent of its theoretical BOD in 21 days, using an activated sludge inoculum(1).12.3 Bioaccumulative potential
An estimated BCF of 250 was calculated for benzoyl peroxide(SRC), using an experimental log Kow of 3.46(1,SRC) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF suggests that bioconcentration in aquatic organisms is high(SRC).12.4 Mobility in soil
The Koc of benzoyl peroxide is estimated as approximately 1,800(SRC), using a measured log Kow of 3.46(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that benzoyl peroxide is expected to have low mobility in soil(SRC).12.5 Other adverse effects
no data available13.Disposal considerations 13.1 Disposal methods Product
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.Contaminated packaging
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.14.Transport information 14.1 UN Number
