Signs and Symptoms of Acute Chloroethanol Exposure: Signs and symptoms of acute exposure to chloroethanol may include weakness, dizziness, confusion, visual disturbances, incoordination, shock, seizures, and coma. Dyspnea (shortness of breath), pulmonary edema, respiratory depression, and respiratory failure may occur. Weak pulse, hypotension (low blood pressure), and cyanosis (blue tint to the skin and mucous membranes) may be observed. Nausea, vomiting, and hematuria (bloody urine) may be seen after exposure. Liver and kidney damage may also occur. Chloroethanol is irritating to the skin and mucous membranes.
Emergency Life-Support Procedures: Acute exposure to chloroethanol may require decontamination and life support for the victims. Emergency personnel should wear protective clothing appropriate to the type and degree of contamination. Air-purifying or supplied-air respiratory equipment should also be worn, as necessary. Rescue vehicles should carry supplies such as plastic sheeting and disposable plastic bags to assist in preventing spread of contamination.
Inhalation Exposure:
1. Move victims to fresh air. Emergency personnel should avoid self-exposure to chloroethanol.
2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support.
3. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.
4. Transport to a health care facility.
Dermal/Eye Exposure:
1. Remove victims from exposure. Emergency personnel should avoid self- exposure to chloroethanol.
3. Remove contaminated clothing as soon as possible.
4. If eye exposure has occurred, eyes must be flushed with lukewarm water for at least 15 minutes.
5. Wash exposed skin areas THOROUGHLY with soap and water.
6. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.
7. Transport to a health care facility.
Ingestion Exposure:
1. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support.
2. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.
3. Give the victims water or milk: children up to 1 year old, 125 mL (4 oz or 1/2 cup); children 1 to 12 years old, 200 mL (6 oz or 3/4 cup); adults, 250 mL (8 oz or 1 cup). Water or milk should be given only if victims are conscious and alert.
4. Activated charcoal may be administered if victims are conscious and alert. Use 15 to 30 g (1/2 to 1 oz) for children, 50 to 100 g (1-3/4 to 3-1/2 oz) for adults, with 125 to 250 mL (1/2 to 1 cup) of water.
5. Promote excretion by administering a saline cathartic or sorbitol to conscious and alert victims. Children require 15 to 30 g (1/2 to 1 oz) of cathartic; 50 to 100 g (1-3/4 to 3-1/2 oz) is recommended for adults.
6. Transport to a health care facility. (EPA, 1998)
General First Aid:
· Call 911 or emergency medical service.
· Ensure that medical personnel are aware of the material(s) involved, take precautions to protect themselves and avoid contamination.
· Move victim to fresh air if it can be done safely.
· Administer oxygen if breathing is difficult.
· If victim is not breathing:
-- DO NOT perform mouth-to-mouth resuscitation; the victim may have ingested or inhaled the substance.
-- If equipped and pulse detected, wash face and mouth, then give artificial respiration using a proper respiratory medical device (bag-valve mask, pocket mask equipped with a one-way valve or other device).
-- If no pulse detected or no respiratory medical device available, provide continuous compressions. Conduct a pulse check every two minutes or monitor for any signs of spontaneous respirations.
· Remove and isolate contaminated clothing and shoes.
· For minor skin contact, avoid spreading material on unaffected skin.
· In case of contact with substance, remove immediately by flushing skin or eyes with running water for at least 20 minutes.
· For severe burns, immediate medical attention is required.
· Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed.
· Keep victim calm and warm.
Do not breathe fumes from burning material. Air purifying respirator or self-contained breathing apparatus, coat, pants, gloves, and boots should be worn. No skin surface should be exposed. Bands around legs, arm and waist should be provided.
Water spray may be used to extinguish the fire because the material can be cooled below its flash point. Alcohol foam, carbon dioxide, and dry chemical may be used. (EPA, 1998)
Use water spray, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
Water, alcohol foam, dry chemical, or carbon dioxide.
Vapors are heavier than air and may flash back to a source of ignition.
· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.
· Keep unauthorized personnel away.
· Stay upwind, uphill and/or upstream.
· Ventilate closed spaces before entering, but only if properly trained and equipped.
· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from 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.
Small Spill
· Absorb with earth, sand or other non-combustible material and transfer to containers for later disposal.
· 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.
Excerpt from ERG Guide 131 [Flammable Liquids - Toxic]:
IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 50 meters (150 feet) in all directions.
SPILL: See ERG Table 1 - Initial Isolation and Protective Action Distances on the UN/NA 1135 datasheet.
FIRE: If tank, rail tank car or highway tank 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, 2024)
Immediate precautionary measure
· Isolate spill or leak area for at least 50 meters (150 feet) in all directions.
· For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.
· For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind direction, as necessary.
· If tank, rail tank car or highway tank 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.
Small spill:
- ISOLATE in all directions: 30 m (100 ft)
Large spill:
- PROTECT people from downwind during DAY time: 0.1 km (0.1 mi)
- PROTECT people from downwind during NIGHT time: 0.1 km (0.1 mi)
Personal protection: complete protective clothing including self-contained breathing apparatus. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
1. Remove all ignition sources. 2. Ventilate area of spill or leak. 3. For small quantities, absorb on paper towels. Evaporate in a safe place (such as a fume hood). Allow sufficient time for evaporating vapors to completely clear the hood ductwork. Burn the paper in a suitable location away from combustible materials. Large quantities can be collected and atomized in a suitable combustion chamber equipped with an appropriate effluent gas cleaning device. Ethylene chlorohydrin should not be allowed to enter a confined space, such as a sewer, because of the possibility of an explosion.
SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
1. By absorbing it in vermiculite, dry sand, earth or a similar material and disposing in a secured sanitary landfill. 2. By atomizing in a suitable combustion chamber equipped with an appropriate effluent gas cleaning device.
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.
Clothing contaminated with liquid ethylene chlorohydrin should be placed in closed containers for storage until it can be discarded or until provision is made for the removal of ethylene chlorohydrin from the clothing. If the clothing is to be laundered or otherwise cleaned to remove the ethylene chlorohydrin, the person performing the operation should be informed of ethylene chlorohydrin's hazardous properties.
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.
The worker should immediately wash the skin when it becomes contaminated.
Work clothing that becomes wet or significantly contaminated should be removed or replaced.

Simultaneous administration of ethyl alcohol increased the LD50 of ethylene chlorohydrin regardless of the route of administration (peroral or percutaneous). Necrotic lesions produced in the liver and kidney by ethylene chlorohydrin were also reduced in number and extent by ethanol. Blood concn of the chlorohydrin were raised by ethanol administration, which suggests that the protective effect is due to competitive inhibition of chlorohydrin metabolism to chloroacetaldehyde.
2-Chloroethanol is thought to interfere with the detoxification mechanisms of the alkaloids. Chickens were administered monocrotaline after separate groups were pretreated with BHA and 2-chloroethanol. There was an apparent deleterious effect of monocrotaline in 2-chloroethanol-pretreated chickens, similar to that in non-pretreated birds, with respect to growth rates, morbility, mortality, and hepatic histopatholoqy. Monocrotaline pyrrole formation was measured in chickens pretread with BHA and 2-chloroethanol by means of the Erlich reagent reaction spectrophotometric assay. There was a significant difference in pyrrole production between the treatment groups. The 2-chloroethanol plus-monocrotaline (40 mg/kg), BHA (500 mg/kg) plus monocrotaline, nonocrotaline, BHA (100 mg/kg) plus monocrotaline (20 mg/kg), and BHA (500 mg/kg) plus 2-chloroethanol and monocrotaline groups had decreasing amounts of pyrrole metabolite formation respectively.
The following medical procedures should be made available to each employee who is exposed to ethylene chlorohydrin at potentially hazardous levels: ... A complete history and physical examination. ... Examination of the respiratory system, liver, kidneys, and central nervous system should be stressed. The skin should be examined for evidence of chronic disorders. ... A profile of liver function should be obtained by using a medically acceptable array of biochemical tests. ... Since kidney damage has been observed from exposure, a urinalysis should be obtained to include at a minimum specific gravity, albumin, glucose, and microscopic /examination/ of centrifuged sediment. ... The aforementioned medical examinations should be repeated on a semi-annual basis for the first two years and annually thereafter.

2-Chloroethanol may be released to the environment during its production, transport, storage, disposal and use. Formerly 2-chloroethanol was a major industrial precursor for ethylene oxide. However, this process for manufacturing ethylene oxide has been almost entirely supplanted. It is also formed during the fumigation of foodstuffs with ethylene oxide. If released on soil, 2-chloroethanol would be expected to leach because of its estimated very low adsorptivity to soil and may biodegrade. It should not volatilize from moist soil, but may evaporate from dry soil and other surfaces. 2- Chloroethanol's fate in the aquatic environment is not clear. Based on data from screening tests, it may biodegrade. It would not be expected to volatilize from surface waters, adsorb to sediment or bioconcentrate in aquatic organisms. 2-Chloroethanol reacts with photochemically-produced hydroxyl radicals in the atmosphere, as a result of which its half-life in the atmosphere will be approximately 11.5 days. 2-Chloroethanol is soluble in water and would be washed out of the air by rain. Occupational exposure to 2- chloroethanol would be via inhalation and dermal contact. The general population may be exposed via ingestion of food containing residues of 2- chloroethanol. (SRC)
2-Chloroethanol may be released to the environment during its production, transport, storage, disposal and use. In past years it was produced in a large scale as an intermediate in the manufacture of ethylene oxide(1) which may have resulted in considerable releases. However, this process has been almost completely supplanted(1). 2-Chloroethanol is produced when polyvinylchloride (PVC) plastics are sterilized with ethylene oxide(1). It is also formed during the fumigation of foodstuffs with ethylene oxide(2).
TERRESTRIAL FATE: If released on soil 2-chloroethanol would be expected to leach because of its estimated very low adsorptivity to soil. In view of its low estimated Henry's Law constant, 1.04X10-7 atm-cu m/mole(1), and low estimated adsortivity to soil, 2-chloroethanol would not be expected to volatilize from moist soil. However, it would be expected to volatilize from dry soil and other surfaces because it's vapor pressure is appreciable, 7.18 mm Hg at 25 °C(2). 2-Chloroethanol was readily biodegradable in screening tests and biological treatment simulations tests which suggest that it may biodegrade in soil(SRC).
AQUATIC FATE: If released in water, the fate of 2-chloroethanol is not clear. In view of its low estimated Henry's Law constant, 1.04X10-7 atm-cu m/mole(1), 2-chloroethanol would not be expected to volatilize from surface waters. It would not be expected to adsorb to sediment, bioconcentrate in fish, photolyze or hydrolyze. However, based on data from screening tests, it may biodegrade(SRC).
ATMOSPHERIC FATE: 2-Chloroethanol reacts with photochemically-produced hydroxyl radicals in the atmosphere and has a rate constant of 1.40X10-12 cu cm/molec-sec(1) for this reaction. Assuming a hydroxyl radical concn of 5X10+5 per cu cm, the half-life of 2-chloroethanol in the atmosphere will be 11.5 days(SRC). 2-Chloroethanol is soluble in water(2) and would be subject to washout by rain.
2-Chloroethanol is readily biodegradable in screening tests and biological treatment simulations using sewage and activated sludge inocula(1-6). Various investigators have obtained the following results in percent of theoretical BOD in screening tests using sewage inocula: 57% in 20 days(1); 50% in 10 days(2); and 87% in 10 days(3). The results of these screening tests indicate that acclimation is important in the biodegradation process.
In two simulated biological treatment plants using activated sludge, 45% removal of 2-chloroethanol in 24 hr was obtained with about 5% due to evaporation(1) and 45% of theoretical BOD was removed in 10 days(2). Results obtained in a biodegradability test performed using process wastewater and activated sludge found a 20% COD removal in conflict to a 1% total organic carbon (TOC) removal in 24 hours(4). 2-Chloroethanol's degradation pathway is via 2-chloroacetaldehyde and monochloroacetate to glycolic acid(3).
2-Chloroethanol reacts with photochemically-produced hydroxyl radicals in the atmosphere with a rate constant of 1.40X10-12 cu cm/molec-sec(1). Assuming a hydroxyl radical concentration of 5X10+5 per cu cm, the half-life of 2-chloroethanol in the atmosphere will be 11.5 days(SRC). 2-Chloroethanol undergoes neutral and acid catalyzed hydrolysis with respective rate constants of 4.5X10-6 1/hr and 36 L/mol-hr at 25 °C(3). The resulting hydrolysis half-life at pH 7 is calculated to be 9.8 yr(3). Haloalcohols do not absorb UV light >290 nm(4) and therefore would not undergo direct photolysis.
Using the log octanol/water partition coefficient for 2-chloroethanol, 0.03(1), one can estimate a BCF of 0.62 using a recommended regression equation(2,SRC). Therefore, 2-chloroethanol would not be expected to bioconcentrate in aquatic organisms.
The Koc for 2-chloroethanol estimated from molecular structure is 1.33(1). According to a suggested classification scheme, a Koc of this magnitude indicates that 2-chloroethanol will exhibit very high mobility in soil(2).
The Henry's Law constant for 2-chloroethanol is estimated to be 1.04X10-7 atm-cu m/mole(1). Such a low Henry's Law constant indicates that volatilization from rivers and lakes will not be an important fate process for 2-chloroethanol(2). In view of its low Henry's Law constant and low estimated adsorptivity to soil, volatilization from moist soil should be negligible(2). 2-Chloroethanol's vapor pressure is 7.18 mm Hg at 25 °C(3) and therefore it should readily volatilize from dry soil and other surfaces.
2-Chloroethanol and 2-chloroethanol fatty acid esters are byproducts of the ethylene oxide fumigation of foods(1). Furthermore, 2-chloroethanol fatty acid esters are hydrolyzed to 2-chloroethanol in model digestive systems(1). The level of 2-chloroethanol found in samples of black walnuts and a variety of spices (item, concn in ppm) was: allspice, 810-880; black pepper, 0.2-45; black walnuts, 1.9-4.8; chili powder, 0.8-45; cocoa, not detected; mint flakes, 0.6; mushrooms, not detected - 0.4; Nacho cheese mix, not detected - 14; nutmeg, 16-37; onion powder, not detected; paprika, not detected - 513; parsley flakes, 0.4; red pepper, 3.6-490; seafood seasoning, 33; taco seasoning, 115-117; vegetable flakes, 0.35-0.6; and white pepper, 0.78(1).
Occupational exposure to 2-chloroethanol would be via inhalation and dermal contact. The general population would be exposed via ingestion of food containing residues of 2-chloroethanol(1,SRC).
NIOSH (NOES Survey 1981-1983) has statistically estimated that 476 workers, including 68 females, are exposed to 2-chloroethanol in the USA(1).
