Fresh air, rest. Half-upright position. Refer for medical attention.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention .
Extremely destructive to tissue of the mucous membranes, upper respiratory tract, eyes, and skin. Symptoms of exposure include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. (USCG, 1999)
Peroxides should be washed promptly from the skin to prevent irritation. In the case of eye contact, the eyes should be flushed immediately with large amounts of water, and medical attention should be obtained. ... Medical attention should also be obtained in case of accidental ingestion. ... Peroxides, Organic and Inorganic
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
Behavior in Fire: Explosive. (USCG, 1999)
Use water spray, powder, carbon dioxide, dry sand, foam. Combat fire from a sheltered position.
Personal protection: chemical protection suit including self-contained breathing apparatus. Collect leaking and spilled liquid in sealable plastic containers as far as possible. Do NOT absorb in saw-dust or other combustible absorbents.

Spills should be cleaned up promptly using non-sparking tools and 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. Peroxides, Organic and Inorganic
NO open flames. NO contact with acids, bases, reducing agents or hot surfaces. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Store only if stabilized. Well closed. See Chemical Dangers.

Heating may cause violent combustion or explosion. On combustion, forms toxic and corrosive gases. The substance is a strong oxidant. It reacts violently with combustible and reducing materials, amines, metals, strong acids and strong bases. This generates fire and explosion hazard.
Unstable agent which like hydrogen peroxide releases oxygen.
METHYL ETHYL KETONE PEROXIDE is a strong oxidizing agent. May be ignited by heat, sparks or flame and undergoes self-accelerating decomposition. Explosive decomposition occurs at 230° F. Sensitive to sunlight. Ignition and/or explosion may occur if mixed with readily oxidizable materials. Reacts with combustible materials such as wood, cloth or organic materials, with chlorine, and with metals (iron, copper and their alloys and aluminum and its alloys). Incompatible with strong oxidizing agents, strong reducing agents, natural rubbers, synthetic rubbers and chemical accelerators. Incompatible with heavy metals, acids and bases.

Vigorous decomp can be stimulated by even trace amt of a wide variety of contaminants, such as strong acids, bases, metals, metal alloys and salts, sulfur cmpd, amines, accelerators or reducing agents. This is particularly true of methyl ethyl ketone and benzoyl peroxides, which are intentionally stimulated to decomp @ room temp using small amt of accelerators.

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). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low. Chemical degradation is expected to be the dominant fate process in water because of reaction with organic matter and therefore, it is doubtful that un-reacted 2-butanone peroxide would be biologically available(SRC).
2-Butanone peroxide is a mixture dimers (50%), trimers (25%), and monomer peroxy compounds(3). Using a structure estimation method based on molecular connectivity indices(1), the Koc for 2-butanone peroxide can be estimated to range from 10 to 11,000(SRC). According to a classification scheme(2), this estimated Koc range suggests that some portions of the 2-butanone peroxide mixture are expected to have very high mobility in soil, whereas other portions of the mixture are expected to be essentially immobile. 2-Butanone peroxide is a strong oxidizing agent(3) and may decompose when brought in contact with organic materials(SRC).

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.
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.
