DOT Emergency Guidelines
/GUIDE 129: FLAMMABLE LIQUIDS (POLAR/WATER-MISCIBLE/NOXIOUS)/ Fire or Explosion: HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with "P" may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
/GUIDE 129: FLAMMABLE LIQUIDS (POLAR/WATER-MISCIBLE/NOXIOUS)/ Health: May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
/GUIDE 129: FLAMMABLE LIQUIDS (POLAR/WATER-MISCIBLE/NOXIOUS)/ Public Safety: CALL Emergency Response Telephone Number ... . As an immediate precautionary measure, isolate spill or leak area for at least 50 meters (150 feet) in all directions. Keep unauthorized personnel away. Stay upwind. Keep out of low areas. Ventilate closed spaces before entering.
/GUIDE 129: FLAMMABLE LIQUIDS (POLAR/WATER-MISCIBLE/NOXIOUS)/ Protective Clothing: Wear positive pressure self-contained breathing apparatus (SCBA). Structural firefighters' protective clothing will only provide limited protection.
/GUIDE 129: FLAMMABLE LIQUIDS (POLAR/WATER-MISCIBLE/NOXIOUS)/ Evacuation: Large spill: Consider initial downwind evacuation for at least 300 meters (1000 feet). Fire: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions.
/GUIDE 129: FLAMMABLE LIQUIDS (POLAR/WATER-MISCIBLE/NOXIOUS)/ Fire: Caution: All these products have a very low flash point: Use of water spray when fighting fire may be inefficient. Small fires: Dry chemical, CO2, water spray or alcohol-resistant foam. Do not use dry chemical extinguishers to control fires involving nitromethane or nitroethane. Large fires: Water spray, fog or alcohol-resistant foam. Do not use straight streams. Move containers from fire area if you can do it without risk. Fire involving tanks or car/trailer loads: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn.
/GUIDE 129: FLAMMABLE LIQUIDS (POLAR/WATER-MISCIBLE/NOXIOUS)/ Spill or Leak: ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. A vapor suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Use clean non-sparking tools to collect absorbed material. Large spills: Dike far ahead of liquid spill for later disposal. Water spray may reduce vapor; but may not prevent ignition in closed spaces.
/GUIDE 129: FLAMMABLE LIQUIDS (POLAR/WATER-MISCIBLE/NOXIOUS)/ First Aid: Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. Wash skin with soap and water. Keep victim warm and quiet. In case of burns, immediately cool affected skin for as long as possible with cold water. Do not remove clothing if adhering to skin. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves.

Reactivities and Incompatibilities
... CAN REACT VIGOROUSLY WITH CHLOROSULFONIC ACID, ... OLEUM, K-TERT-BUTOXIDE ...Explosive reaction with lithium tetrahydroaluminate.
Incompatible with nitrates, strong oxidizers, strong alkalies, strong acids.
Nitrates, strong oxidizers, alkalis & acids.
Other Preventative Measures
Employees should wash promptly when skin is wet or contaminated. Remove clothing immediately if wet or contaminated to avoid flammability hazard.
Avoid breathing vapors. Keep upwind. Wear appropriate chemical protective gloves, boots and goggles. Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water.
SRP: 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.
If material not on fire and not involved in fire: Keep sparks, flames and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard. Use water spray to disperse vapors and dilute standing pools of liquid.
SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
The worker should immediately wash the skin when it becomes contaminated.
Work clothing that becomes wet should be immediately removed due to its flammability hazard.
An analysis of breakthrough times of low boiling organic solvent vapors in a commercial respirator cartridge under steady state and pulsating flow conditions was performed. A KGC-8 respirator cartridge packed with 22.5 grams of activated charcoal was exposed to 0, 100, 300, or 900 ppm carbon-tetrachloride, ethyl-acetate, methyl-acetate, acetone, or dichloromethane vapor under steady state or pulsed flow conditions in custom built apparatus. The steady state flow condition was achieved by setting the respirator cartridge in its holder and passing each solvent vapor through it at a flow rate of 30 liter per minute (l/min). The pulsating flow condition was achieved placing the respirator cartridge in a Tedler bag, expanding the bag by introducing each test vapor, and 'inhaling' the test vapor through the respirator cartridge using a breathing machine drawing 1.5 liters air per cycle at the rate 20 cycles/min. The total flow rate was adjusted to be similar to the 301/min rate utilized the steady state flow experiments. Solvent vapor concentrations were measured upstream and downstream from the cartridge by gas chromatography. Breakthrough times were determined as the time required for the solvent vapor concentrations downstream from the cartridge to increase to 5 ppm. The data were analyzed by logistic regression techniques. After converting the data to logarithms, the breakthrough times of all five solvents were linearly, inversely proportional to their initial concentrations under both steady state and pulsed flow conditions. The slopes of the lines were smaller for the solvents with the lower boiling points. The ratios of the breakthrough times measured under the pulsating flow to the steady slate flow condition (B/A ratio) varied from 0.77 to 0.71 for dichloromethane. The B/A ratios for the lOO ppm initial concentrations of the other four solvents varied only from 0.95 to 1.01. This indicated that except in the case of dichloromethane, there are no large differences in breakthrough tire under the two different flow conditions at lOO ppm. At the other concentrations, in each experiment as the concentration of the test vapor increased the breakthrough times under the pulsating flow condition became shorter compared to the steady state flow condition. /It was/ concluded that breakthrough of low boiling solvent vapors in respirator cartridges occurs earlier under pulsating flow than under steady state conditions.

12.2 Persistence and degradability

AEROBIC: Ethyl acetate, present at 100 mg/L, reached 95% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). A review concluded that ethyl acetate is easily removed by biological treatment(2). Reported 5 day BOD values using a sewage inoculum range from 36-68% of theoretical(3-6) with the value being somewhat reduced in salt water(3). One investigator reported that ethyl acetate was completely degraded in 20 hr using activated sludge(7). In a bench-scale continuous-flow activated sludge reactor with an 8 hour retention time, 99.9% removal including 17% volatilization loss) was obtained, with 80% of the theoretical BOD(8). Ethyl acetate was 90% biooxidized in a 20-day BOD test using a filtered raw sewage seed; it was biooxidized 77% in a 28-day OECD closed-bottle test(9). A screening procedure that was systematically applied to a large number of organic chemicals ranked ethyl acetate as being completely biodegraded in a short time by general microorganisms(10). After a 5 hr lag, 43 to 53% of theoretical BOD was obtained in 50 to 70 hr(10). In screening tests, ethyl acetate, present at a concentration of 5 ppm, reached 26.6 and 57.1% of its theoretical BOD in 5 days using the standard dilution method and seawater dilution method, respectively(11). 99.9% removal of ethyl acetate was observed in a complete mix continuous-flow activated sludge system; 93% of this removal was attributed to biodegradation(12).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated for ethyl acetate(SRC), using a log Kow of 0.73(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(SRC).

12.4 Mobility in soil

The Koc of ethyl acetate is estimated as 18(SRC), using a log Kow of 0.73(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that ethyl acetate is expected to have very high mobility in soil(SRC). A log Ki (snow surface/air (cu m/sq m)) of -3.69 has been reported for sorption to snow(4).

13.Disposal considerations

13.1 Disposal methods


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.
