Spills should be cleaned up promptly using non-sparking tools and an inert, moist diluent such as vermiculite or sand. May be ignited by heat, sparks or flame and undergoes self-accelerating decomposition. Handle with gloves. Wash hands before breaks and at the end of workday. Remove contaminated clothes. P363 Wash contaminated clothing before reuse. P210 Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. Synonym: 2-Butanone peroxide solution, Methyl ethyl ketone peroxide solution Linear Formula: C 2 H 5 C(OOH)(CH 3 )OOC(OOH)(CH 3 )C 2 H 5 Molecular Weight: 210.22 Systematic Name: 2-Butanone, peroxide CAS Number: 1338-23-4. Exit. Acute (short-term) inhalation exposure to methyl ethyl ketone in humans results in irritation to the eyes, nose, and throat. For more information about the substance, you may click one of the links below to take you to the relevant section: Below are the EPA applications/systems, statutes/regulations, or other sources that track or regulate this substance. Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low. Gloves must be inspected prior to use. Benzoyl peroxide can be used for the same purpose. This is particularly true of methyl ethyl ketone and benzoyl peroxides, which are intentionally stimulated to decomp @ room temp using small amt of accelerators. Do NOT induce vomiting. An estimated BCF of 13 was calculated for the 2-butanone peroxide mixture(SRC), using an estimated log Kow of 2(1) and a regression-derived equation(2). Internal Tracking Number: 85969. Dilute solutions of 30 to 40% MEKP are used in industry and by hobbyists as the catalyst which initiates the crosslinking of unsaturated polyester resins used in fiberglass, and casting. Ignition and/or explosion may occur if mixed with readily oxidizable materials. UNSTABLE AGENT WHICH LIKE HYDROGEN PEROXIDE RELEASES OXYGEN. 2-Butanone peroxide is a strong oxidizing agent(3) and may decompose when brought in contact with organic materials(SRC). The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. For this application, MEKP is dissolved in dimethyl phthalate, cyclohexane peroxide, or diallyl phthalate to reduce sensitivity to shock. No smoking. Symptoms of exposure include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Synonyms & Trade Names.

Ensure adequate ventilation. P321 Specific treatment (see ... on this label). Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. This table shows how each list refers to the substance. Gives off irritating or toxic fumes (or gases) in a fire. Some of the following links exit EPA's site Methyl ethyl ketone peroxide (CAS No. Incompatible with strong oxidizing agents, strong reducing agents, natural rubbers, synthetic rubbers and chemical accelerators. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it. P270 Do not eat, drink or smoke when using this product. Spilled, contaminated, waste or questionable peroxides should be destroyed. Extremely destructive to tissue of the mucous membranes, upper respiratory tract, eyes, and skin. MEKP is a colorless, oily liquid whereas acetone peroxide is a white powder at STP; MEKP is slightly less sensitive to shock and temperature, and more stable in storage. Rinse mouth.
