- First Aid: 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) shou Source: CAMEO Chemicals

- Environmental Bioconcentration: An estimated BCF of 3 was calculated in fish for diethylene glycol(SRC), using an estimated log Kow of -1.5(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). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1(SRC), determined from a structure estimation method(2), indicates that diethylene glycol is expected to have very high mobility in soil(SRC). Volatilization of diethylene glycol from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.0X10-9 atm-cu m/mole(SRC), using a fragment constant estimation method(3). Diethylene glycol is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 5.7X10-3 mm Hg at 25 °C(4). Diethylene glycol was readily biodegraded in a sandy loam(5) suggesting that biodegradation is an important environmental fate process in soil(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1(SRC), determined from a structure estimation method(2), indicates that diethylene glycol is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 2.0X10-9 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). According to a classification scheme(6), an estimated BCF of 3(SRC), from an estimated log Kow of -1.5(7) and a regression-derived equation(8), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Diethylene glycol was biodegraded partially from river water within 7 days at 20 °C, but under winter conditions of river flow and temperature (less than 8 °C) degradation was minimal(9). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), diethylene glycol, which has a vapor pressure of 5.7X10-3 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase diethylene glycol 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 17 hrs(SRC), calculated from its rate constant of 3.0X10-11 cu cm/molecule-sec at 25 °C(3). Diethylene glycol degraded 5.5% by light at a wavelength greater than 290 nm over a period of 17 hours(4) and therefore may be susceptible to direct photolysis by sunlight(SRC).
