ETHYLENE GLYCOL DIACETATE reacts with aqueous acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction with caustic solutions. Flammable hydrogen is generated with alkali metals and hydrides.

Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]: As an immediate precautionary measure, isolate spill or leak area for at least 50 meters (150 feet) in all directions. 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. (ERG, 2016)

Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]: 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 SPILL: Dike far ahead of liquid spill for later disposal. Water spray may reduce vapor, but may not prevent ignition in closed spaces. (ERG, 2016)

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. Use water spray to knock-down vapors.|Personnel protection: Avoid breathing vapors. Keep upwind. Avoid bodily contact with the material. ... 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. Wear positive pressure self-contained breathing apparatus when fighting fires involving this material. If contact with the material anticipated, wear appropriate chemical protective clothing.

LIQUID CAUSES MILD IRRITATION OF EYES.

This action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. Ethylene glycol diacetate is produced, as an intermediate or final product, by process units covered under this subpart.

TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 10(SRC), determined from a structure estimation method(2), indicates that ethylene glycol diacetate should have very high mobility in soil(SRC). Volatilization of ethylene glycol diacetate is not expected to be important from moist soil surfaces(SRC) given an estimated Henry's Law constant of 8.4X10-8 atm-cu m/mole(SRC), calculated from experimental values of vapor pressure(3) and water solubility(4) but may occur from dry soil surfaces(SRC), based on an experimental vapor pressure of 7.74X10-2 mm Hg(3). Ethylene glycol diacetate is expected to biodegrade in soil based on Hach respirometric and OECD Screening (die-away) tests using sewage inocula(4).|AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 10(SRC), determined from a structure estimation method(2), indicates that ethylene glycol diacetate would not adsorb to suspended solids and sediment(SRC) in the water. Ethylene glycol diacetate will be essentially non-volatile from water surfaces based on an estimated Henry's Law constant of 8.4X10-8 atm-cu m/mole(SRC), calculated from experimental values for vapor pressure (3) and water solubility(4). An estimated BCF value of 1.2(1,SRC), from an estimated log Kow(5,SRC), suggests that ethylene glycol diacetate will not bioconcentrate in aquatic organisms(SRC), according to a recommended classification scheme(6). The half-lives for the base-catalyzed hydrolysis of ethylene glycol diacetate have been estimated to be 15 days at pH of 8 and 152 days at a pH of 7(7,SRC). Ethylene glycol diacetate is expected to biodegrade in water based on Hach respirometric and OECD Screening (die-away) tests using sewage inocula(8).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), ethylene glycol diacetate, which has an experimental vapor pressure of 7.74X10-2 mm Hg at 25 °C(2), will exist as a vapor in the ambient atmosphere. Vapor-phase ethylene glycol diacetate is degraded in the atmosphere by reaction with photochemically produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be about 4.1 days(3,SRC).

The rate constant for the vapor-phase reaction of ethylene glycol diacetate with photochemically produced hydroxyl radicals has been estimated as 3.9X10-12 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1,SRC). This corresponds to an atmospheric half-life of about 4.1 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1,SRC). Ethylene glycol diacetate has a base-catalyzed hydrolysis rate constant of 5.3X10-1 L/mol-sec which corresponds to half-lives of 15 days at pH of 8 and 152 days at a pH of 7(2,SRC).

An estimated BCF value of 1.2 was calculated for ethylene glycol diacetate(SRC), using an estimated log Kow of 0.4(1,SRC) and a recommended regression-derived equation(2). According to a recommended classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms will not be an important fate process(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc for ethylene glycol diacetate can be estimated to be about 10(SRC). According to a recommended classification scheme(2), this estimated Koc value suggests that ethylene glycol diacetate should have very high mobility in soil(SRC).

The Henry's Law constant for ethylene glycol diacetate is estimated as 8.4X10-8 atm-cu m/mole(SRC) from its experimental values for vapor pressure, 7.74X10-2 mm Hg(1), and water solubility, 1.78X10+5 mg/l(2). This value indicates that ethylene glycol diacetate will be essentially nonvolatile from water surfaces(3,SRC). Ethylene glycol diacetate's vapor pressure(1) and Henry's Law constant(1,2,SRC) indicate that volatilization from dry soil surfaces may occur, but volatilization from moist soil surfaces is not expected to occur(SRC).

Ethylene glycol diacetate has been identified as a volatile component of chicken(1).

NIOSH (NOES Survey 1981-1983) has statistically estimated that 1,417 workers are potentially exposed to ethylene glycol diacetate in the USA(1).

Inhalation is not hazardous. Liquid causes mild irritation of eyes. Ingestion causes stupor or coma. (USCG, 1999)

EYES: 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 area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing. INGESTION: DO NOT INDUCE VOMITING. 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. Be prepared to transport the victim to a hospital if advised by a physician. 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. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)
