4.2 Most important symptoms/effects, acute and delayedVapors irritate eyes and nose. Ingestion or skin contact causes headache, nausea, vomiting, dizziness. (USCG, 1999)
4.3 Indication of immediate medical attention and special treatment needed, if necessaryImmediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Ethylene glycol, glycols, and related compounds/
5.Fire-fighting measures 5.1 Extinguishing media Suitable extinguishing mediaCarbon dioxide or dry chemical for small fires; alcohol-type foam for large fires.
5.2 Specific hazards arising from the chemicalExcerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]: 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 or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with a (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. Substance may be transported hot. For hybrid vehicles, ERG Guide 147 (lithium ion batteries) or ERG Guide 138 (sodium batteries) should also be consulted. If molten aluminum is involved, refer to ERG Guide 169. (ERG, 2016)
5.3 Special protective actions for fire-fightersWear self-contained breathing apparatus for firefighting if necessary.
6.Accidental release measures 6.1 Personal precautions, protective equipment and emergency proceduresUse personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.
6.2 Environmental precautionsPersonal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Remove all ignition sources. Collect leaking and spilled liquid in sealable containers as far as possible. Wash away remainder with plenty of water.
6.3 Methods and materials for containment and cleaning upVentilate area of spill or leak. For small quantities, absorb on paper towels. Evaporate in safe place (such as fume hood). Allow sufficient time for evaporating vapors to completely clear hood ductwork. Burn paper in suitable location away from combustible materials. Large quantities can be collected and atomized in suitable combustion chamber. Waste disposal: By absorbing it in vermiculite, dry sand, earth or similar material and disposing in secured sanitary landfill; By atomizing in suitable combustion chamber.

CarcinogenicityWEIGHT-OF-EVIDENCE CHARACTERIZATION: No reliable human epidemiological studies are available that address the potential carcinogenicity of EGBE. ... NTP /the National Toxicology Program/ reported no evidence of carcinogenic activity in male F344/N rats, and equivocal evidence of carcinogenic activity in female F344/N rats on the basis of increased combined incidences of benign and malignant pheochromocytoma (mainly benign) of the adrenal medulla. They also reported some evidence of carcinogenic activity in male B6C3F1 mice on the basis of increased incidences of hemangiosarcoma of the liver, and some evidence of carcinoma (mainly papilloma). ... because of the uncertain relevance of these tumor increases to humans, the fact that EGBE is generally negative in genotoxic tests and the lack of human data to support the findings in rodents, the human carcinogenic potential of EGBE, in accordance with the recently proposed Guidelines for Carcinogen Risk Assessment, cannot be determined at this time, but suggestive evidence exists from rodent studies. Under existing EPA guidelines, EGBE is judged to be a possible human carcinogen, Group C. There are currently no human epidemiological studies addressing the potential carcinogenicity of EGBE.

AEROBIC: A number of aerobic biological screening studies, which utilized settled waste water, sewage, or activated sludge for inocula, indicate that ethylene glycol mono-n-butyl ether should biodegrade rapidly in the environment(1-4). Five and ten-day Theoretical BOD values were 73% (with acclimation)(1) and 74%(2). The maximum Theoretical BOD reported was 88% for 20 days(2).
12.3 Bioaccumulative potentialAn estimated BCF of 3 was calculated for ethylene glycol mono-n-butyl ether(SRC), using an estimated log Kow of 0.83(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 soilThe Koc of ethylene glycol mono-n-butyl ether is estimated as 8(SRC), using a log Kow of 0.83(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that ethylene glycol mono-n-butyl ether is expected to have high mobility in soil.
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe 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 packagingContainers 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.
