화재 위험Behavior in Fire: Explosive. (USCG, 1999)Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion on contact with acids, bases or reducing agents.
건강 유해성Extremely 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)
유해성 요약Liquid causes second or third degree burns after short contact. [CHRIS] Corrosive to the eyes, skin, and upper respiratory tract[ICSC] After ingestion, effects include corrosion and hepatic failure. [HSDB]The major hazards encountered in the use and handling of 2-butanone peroxide stem from its toxicologic properties and explosivity. Toxic by all routes (ie, inhalation, ingestion, dermal absorption), exposure to this colorless liquid may occur from its production or use as a curing agent for plastics and polyester resins, and as an initiator in the manufacture of polymers. Effects from exposure may include contact burns to the skin and eyes, hemolytic anemia, shortness-of-breath, or pulmonary edema. OSHA has established a Ceiling limit of 0.7 ppm as a final rule to become effective December 31, 1992. In activities and situations where over-exposure may occur, wear a self-contained breathing apparatus and personal protective clothing. If contact should occur, irrigate exposed eyes with copious amounts of water for at least 30 minutes, and exposed skin for at least 15 minutes. Contaminated clothing and shoes should be removed at the site. 2-Butanone peroxide may be ignited by heat, sparks, or flamesburning rapidly and producing poisonous gases. Containers of this substance may explode from friction, heat, mechanical shock, or contamination (such as from trace amounts of strong acids, bases, metals, metal alloys, salts, sulfur compounds, amines, accelerators, or reducing agents). For fires involving this substance, extinguish with dry chemical, CO2, regular foam, or water (used in flooding quantities for large fires). Fight fire from as far a distance as possible, in an explosion-resistant location. Isolate the area for 1/2 mile in all directions if a tank, rail car, or tank truck is involved. 2-Butanone peroxide should be stored in cool, ventilated areas, away from sunlight, sources of ignition, physical damage, shock, and organic or flammable materials. Smalls spills of this substance should be taken up with a noncombustible absorbent such as vermiculite and placed in a plastic container for immediate disposal.

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 .
응급 처치EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.INHALATION: IMMEDIATELY leave the contaminated areatake deep breaths of fresh air. IMMEDIATELY call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be usedif not available, use a level of protection greater than or equal to that advised under Protective Clothing.INGESTION: DO NOT INDUCE VOMITING. Corrosive chemicals will destroy the membranes of the mouth, throat, and esophagus and, in addition, have a high risk of being aspirated into the victim's lungs during vomiting which increases the medical problems. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. IMMEDIATELY transport the victim to a hospital. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. Transport the victim IMMEDIATELY to a hospital.

누출 처리Personal 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.
Preventive MeasuresSRP: 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.The worker should immediately wash the skin when it becomes contaminated.Work clothing that becomes wet or significantly contaminated should be removed and replaced.
Isolation and EvacuationExcerpt from ERG Guide 145 [Organic Peroxides (Heat and Contamination Sensitive)]:IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.LARGE SPILL: Consider initial evacuation for at least 250 meters (800 feet) in all directions.FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directionsalso, consider initial evacuation for 800 meters (1/2 mile) in all directions.

Eye PreventionWear face shield or eye protection in combination with breathing protection.
상호 작용Vitamin E, selenium, vitamin C, & methionine were admin to rats in various combinations by diet & ip injections to rank the individual & combined protective ability of the biological antioxidants at minimum daily requirement levels & at pharmacological levels against lipid peroxidation initiated by 50 mg methyl ethyl ketone peroxide (MEKP)/kg. In vivo lipid peroxidation was monitored throughout a 3 hr period by measuring pentane expired in the breath. Rats fed 30 IU DL-alpha-tocopherol acetate/mg diet significantly decreased pentane production at 20 min by 88% compared to rats fed a vitamin E- & selenium-deficient diet. Rats given 5 ip injections of 180 IU DL-alpha-tocopherol acetate/kg further reduced expired pentane by 83% beyond the protection afforded by dietary vitamin E. Neither additive nor synergistic protection was found when other antioxidants were given in combination with vitamin E. Vitamin E was primary protective antioxidant. Pentane expired by individual rats from various treatment groups strongly correlated with the plasma vitamin E status.Male Sprague-Dawley rats were fed 0, 3, 5 or 10 IU of DL-alpha-tocopherol acetate per kg of diet for 12 wk. After 11 weeks they were injected with 3.3 mg of methyl ethyl ketone peroxide (MEKP)/kg body wt & after 12 wk with 13 mg methyl ethyl ketone peroxide/kg body wt 3-4 hr before decapitation. In the absence of vitamin E, rat brain DNA was significantly damaged by the formation of DNA-protein crosslinks & interstrand DNA crosslinks. Adequate dietary vitamin E protected against this damage. 10 IU/kg was the adequate dose.In vivo, methyl ethyl ketone peroxide damaged microsomal cytochrome p450 and chytochrome p450 mediated peroxidase in vitamin E-deficient rat liver. Dietary vitamin E treatment of rats protected the microsomal enzymes from peroxide damage. In vivo, adequate levels of vitamin E and of NADH and NADPH are probably necessary to provide important protection to the endoplasmic reticulum during metabolism of methyl ethyl ketone peroxide.The tumor promoting effect of methyl ethyl ketone peroxide and the influence of diethyl maleate on this effect, with ultraviolet radiation as the tumor initiator, was studied in hairless albino mutant mice. Four groups of 24 animals were irradiated with ultraviolet light at a daily dose of 2,054 Joules/sq m, 5 days per week. Three weeks after completion of irradiation, the animals received skin applications twice weekly for 25 weeks of either 1 microgram per microliter diethyl maleate in acetone, acetone alone followed by 0.5 microgram per microliter methyl ethyl ketone peroxide in dibutyl phthalate, or dibutyl phthalate alone. Other groups of animals were treated with chemicals without ultraviolet light pretreatment. The animals were killed after 46 weeks and examined for tumors. The great majority of animals with tumors were in the irradiated groups. The highest tumor yield occurred in mice exposed to both dibutyl phthalate and methyl ethyl ketone peroxide after untraviolet light. Dibutyl maleate alone had no measureable effect on the development of tumors. Methyl ethyl ketone peroxide produced an increase in tumor prevalence, but the effect was less marked than in the combined presence of methyl ethyl ketone peroxide and diethyl maleate.

환경 거동TERRESTRIAL FATE: 2-Butanone peroxide is a mixture of dimers (50%), and trimers (25%), and monomer peroxy compounds(5). Based on a classification scheme(1), an estimated Koc range of 10 to 11,000(SRC), determined from a structure estimation method(2), indicates that 2-butanone peroxide's mobility in soil is expected to range from very high, to essentially immobile based upon an estimated Koc range of 10 to 11,000(SRC). Volatilization of 2-butanone peroxide from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant range of 1X10-10 to 2X10-8 atm-cu m/mole(SRC), using a fragment constant estimation method(3). 2-Butanone peroxide is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure range of 1.4X10-3 to 2X10-3 mm Hg(SRC), determined from a fragment constant method(4).AQUATIC FATE: 2-Butanone peroxide is a mixture dimers (50%), trimers (25%), and monomer peroxy compounds(8). Based on a classification scheme(1), an estimated Koc range of 10 to 11,000(SRC), determined from an estimation method(2), indicates that some portions of 2-butanone peroxide mixture are not expected to adsorb to suspended solids and sediment(SRC), other portions of the mixture are expected to adsorb strongly. 2-Butanone peroxide may react with organic materials in water expected(3) based upon estimated Henry's Law constants ranging between 1X10-10 and 2X10-8 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). According to a classification scheme(5), an estimated BCF of 13(SRC), from an estimated log Kow of 2(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low.ATMOSPHERIC FATE: 2-Butanone peroxide is a mixture dimers (50%), trimers (25%), and monomer peroxy compounds(4). According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), the 2-butanone peroxide mixture, which has estimated vapor pressures ranging between 1.4X10-3 and 2X10-3 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely in the vapor-phase in the ambient atmosphere. Vapor-phase 2-butanone peroxide is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to range from 1.5 to 2 days(SRC), calculated from its rate constant range of 9X10-12 to 11X10-12 cu cm/molecule-sec at 25 °C(SRC)determined using a structure estimation method(3).
