Section 4. First-Aid Measures

Fresh air, rest. Refer immediately for medical attention.

Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer immediately for medical attention .

Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.

Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.

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. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.

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. Corrosive chemicals will destroy the membranes of the mouth, throat, and esophagus and, in addition, have a high risk of being aspirated into the victim's lungs during vomiting which increases the medical problems. 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. IMMEDIATELY transport the victim to a hospital. 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. Transport the victim IMMEDIATELY to a hospital. (NTP, 1992)

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.

· Stop leak if you can do it without risk.

· Prevent entry into waterways, sewers, basements or confined areas.

· Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers.

· DO NOT GET WATER INSIDE CONTAINERS.

Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.

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 in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

· 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.

Personal protection: filter respirator for ammonia and organic ammonia derivatives adapted to the airborne concentration of the substance. Collect leaking liquid in sealable plastic containers. Absorb remaining liquid in inert absorbent. Then wash away with plenty of water. Do NOT let this chemical enter the environment.

Accidental release measures. Personal precautions, protective equipment and emergency procedures: Use personal protective equipment. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. Evacuate personnel to safe areas. Beware of vapors accumulating to form explosive concentrations. Vapors can accumulate in low areas.; Environmental precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided.; Methods and materials for containment and cleaning up: Contain spillage, and then collect with an electrically protected vacuum cleaner or by wet-brushing and place in container for disposal according to local regulations ... Keep in suitable, closed containers for disposal.

1. Remove all ignition sources. 2. Ventilate area of spill or leak. 3. If in liquid form, 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 reclaimed or collected and atomized in a suitable combustion chamber equipped with an appropriate effluent gas cleaning device. 4. If in solid form, allow to melt and follow (3) above.

SRP: Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in air, soil or water; effects on animal, aquatic and plant life; and conformance with environmental and public health regulations. If it is possible or reasonable use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination.

Product: This combustible material may be burned in a chemical incinerator equipped with an afterburner and scrubber. Offer surplus and non-recyclable solutions to a licensed disposal company. Contact a licensed professional waste disposal service to dispose of this material. Contaminated packaging: Dispose of as unused product.

SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits 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.

SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants. Ensure that the local ventilation moves the contaminant away from the worker.

Precautions for safe handling: Avoid contact with skin and eyes. Avoid inhalation of vapor or mist. Keep away from sources of ignition - No smoking. Take measures to prevent the build up of electrostatic charge.

Appropriate engineering controls: Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.

IDENTIFICATION AND USE: 2-Aminoethanol is a colorless, viscous liquid or solid (below 51 °F). It is not registered for current pesticide use in the U.S., but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses. The dual function groups, amino and hydroxyl, make it useful in cutting fluids and as intermediates in the production of surfactants, soaps, salts, corrosion control inhibitors, and in pharmaceutical and miscellaneous applications. 2-Aminoethanol and other amines appear to be potentially useful components of topical formulations used to decontaminate and protect the skin against chemical warfare agents. As a pharmaceutical adjuvant, it is used as a solvent for fats and oils, and in combination with fatty acids forms soaps in the formulations of various types of emulsion such as lotions and creams. It is used in hydraulic fracturing. HUMAN EXPOSURE AND TOXICITY: A concentration of 5.9% is irritating to human skin. Symptoms associated with CNS depression in humans include increased blood pressure, diuresis, salivation, and pupillary dilation. Large doses produce sedation, coma, and death following depression of blood pressure and cardiac collapse. 2-Aminoethanol inhalation by humans has been reported to cause immediate allergic responses of dyspnea and asthma and clinical symptoms of acute liver damage and chronic hepatitis. ANIMAL STUDIES: Undiluted liquid causes redness and swelling when applied to the skin of the rabbit. Administration of 2-aminoethanol by the intravenous route in dogs produced increased blood pressure, diuresis, salivation, and pupillary dilation. Rats, mice, rabbits, and guinea pigs exposed to vapor or mist at high concentrations (up to 1250 ppm) developed pulmonary, hepatic, and renal lesions. In a 90-day subacute oral toxicity study of 2-aminoethanol in rats that a maximum daily dose of 0.32 g/kg resulted in no effect; 0.64 g/kg/day resulted in altered liver or kidney wt; and at 1.28 g/kg death occurred. It is considered to be liver toxin. No treatment-related effects were noted in dogs administered as much as 22 mg/kg/d of 2-aminoethanol for 2 yr. In developmental studies in rabbits maternal toxicity was seen at the two higher dose levels (25, 75 mg/kg body weight) as skin irritation and at the highest dose level as reduced weight gain. There was no treatment related effect on the incidence of any fetal variation or malformation or on the number of malformed fetuses. 2-Aminoethanol has been demonstrated to be non-mutagenic in the Ames Salmonella typhimurium assay, with and without S9 metabolic activation, using TA 1535, TA 1537, TA 1538, TA 98, and TA 100; and also negative in the Escherichia coli assay, Saccharomyces gene conversion assay, and rat liver chromosome assay. ECOTOXICITY STUDIES: Aquatic toxicity tests were conducted using zebra fish fry (Brachydanio rerio) and the unicellular algae Isochrysis galbana (a flagellate) and Chaetoceros gracilis (a diatom). Inhibition of cell division, chlorophyll content, and (14)CO2 uptake in the algae were sensitive end points. 2-Aminoethanol had an LC50 /in the zebra fish fry/ higher than 5,000 mg/L.

... Here we investigated hair dye-induced dermatitis and hair loss using in vivo mouse model to uncover the causative ingredients. Commercially available hair dye products or combination of the ingredients of hair dye product were applied topically for 3 days on the dorsum of the female C57BL/6 mice and, dermatitis and hair loss were examined. The mice treated with hair dye products exhibited unequivocal signs of hair loss and dermatitis. To find out causative ingredients, combinations of the representative components of hair dye including reducing agents, the mixture of dye and monoethanolamine (MEA), ammonia, and hydrogen peroxide (H(2)O(2)) were applied and thereafter, hair loss and dermatitis were evaluated. All the groups treated with the combinations containing H(2)O(2) and neutralized dye mixture manifested hair loss and dermatitis. Subsequent experiments revealed that H(2)O(2) and MEA synergistically induced hair loss and dermatitis. Histological examination showed that oxidative stress may be the mechanism underlying hair-dye induced dermatitis. Consistently, H(2)O(2) and MEA synergistically induced oxidative stress and cytotoxicity in human keratinocytes. These results suggest that H(2)O(2) and MEA may be the key causative ingredients for hair dye-associated dermatitis and hair loss.

With monoethanolamine, if symptoms develop or overexposure is suspected, the following may be useful: liver and kidney function tests. Evaluation by a qualified allergist, including careful exposure history and special testing, may help diagnose skin allergy.

/HUMAN EXPOSURE STUDIES/ Numerous publications address the skin sensitizing potential of the short chain alkanolamines triethanolamine (TEA), diethanolamine (DEA), monoethanolamine (MEA), which are not skin sensitizing according to animal studies ... MEA and DEA were patch tested ... in 9602 and 8791 patients, respectively when prevalence of contact allergy was 3.8% and 1.8%. MEA is the prominent allergen in metalworkers with exposure to water-based metalworking fluids (wbMWFs); DEA is probably used in cutting fluids less frequently nowadays. Chronic damage to the skin barrier resulting from wbMWF, the alkalinity of ethanolamines (increasing from TEA to MEA), and other cofactors may contribute to a notable sensitization risk.

/SIGNS AND SYMPTOMS/ ... When undiluted monoethanolamine is applied to human skin on gauze for 1 1/2 hr, only marked redness and infiltration of the skin result.

/SIGNS AND SYMPTOMS/ ... A concentration of 5.9% ethanolamine is irritating to human skin.

/SIGNS AND SYMPTOMS/ Symptoms associated with /CNS depression/ of the ethanolamines /in humans/ include increased blood pressure, diuresis, salivation, and pupillary dilation. Large doses produce sedation, coma, and death following depression of blood pressure and cardiac collapse. /Ethanolamines/

/AQUATIC SPECIES/ Monoethanolamine (MEA), diethanolamine (DEA) and triethanolamine (TEA) are compounds with potential acute, sub-chronic and chronic toxicity effects towards aquatic species. A literature review highlighted the existence of a gap in the knowledge on their toxicity with saltwater testing species. A battery of toxicity tests including the alga Phaeodactylum tricornutum Bohlin, the bivalve molluscs Crassostrea gigas (Thunberg) and Mytilus galloprovincialis (Lmk), and the crustacean Artemia franciscana, was considered to update and improve the existing ecotoxicological information. Data were provided as the Effective Concentration that induces a 50% effect in the observed population (EC50), Lowest Observed Effect Concentration (LOEC) and No Observed Effect Concentration (NOEC). EC50, LOEC and NOEC values were compared with a reviewed database containing the existing ecotoxicological data from saltwater organisms.

/AQUATIC SPECIES/ The influence of monoethanolamine (MEA) as a CO(2) absorbent on photoautotrophic culture of CO(2)-fixing microalgae was investigated. When 300 ppm MEA (4.92 mM) was added to blank culture medium, the dissolved inorganic carbon and the molar absorption ratio increased to 51.0 mg/L and 0.34 mol CO2 = mol MEA, respectively, which was an almost 6-fold increase in CO(2) solubility. When free MEA up to 300 mg/L was added to a green alga Scenedesmus sp. culture that was supplied 5% (v/v) CO(2) at 0.1 vvm, both cell growth rate and final cell density were enhanced compared to when no MEA was added. The cell growth rate reached 288.6 mg/L/d, which was equivalent to 539.6 mg CO(2)/L/d as a CO(2)-fixation rate and enhancement of about 63.0% compared to not adding MEA. Chlorophyll-a content and nitrate consumption rate increased correspondingly. MEA doses higher than 400mg/L inhibited cell growth, probably due to toxicity of the carbamate intermediate.

/AQUATIC SPECIES/ ... Aquatic toxicity tests were conducted using zebra fish fry (Brachydanio rerio) and the unicellular algae Isochrysis galbana (a flagellate) and Chaetoceros gracilis (a diatom). Inhibition of cell division, chlorophyll content, and (14)CO2 uptake in the algae were sensitive end points. ... Monoethanolamine had an LC50 /in the zebra fish fry/ higher than 5,000 mg/L.

/PLANTS/ The cowpea aphid Aphis craccivora that infests the black locust Robinia pseudoacacia shows toxicity to its predator, the multicolored Asian ladybird beetle, Harmonia axyridis. In contrast, the same aphid species that infests the common vetch, Vicia angustifolia, is suitable prey for H. axyridis larvae. Previously, it was reported that the toxicity of A. craccivora infesting R. pseudoacacia was due to canavanine and 2-aminoethanol, but there was some doubt about the toxicity of these compounds and their concentrations in the aphids. In the present study, we determined the concentrations of cyanamide, canavanine, and 2-aminoethanol in A. craccivora infesting the two host plants. In the extracts of A. craccivora that infested either of the host plants, canavanine was undetectable, and 2-aminoethanol was detected at the concentration of 3.0-4.0 ug/g fresh weight. Cyanamide was detected in the extract of A. craccivora that infested R. pseudoacacia (7.7 ug/g fresh weight) but not in that infesting V. angustifolia. The toxicity of canavanine, 2-aminoethanol, and cyanamide was evaluated against H. axyridis larvae in a bioassay by using an artificial diet containing these compounds at various concentrations. Cyanamide exhibited 10-100 times stronger toxicity than canavanine and 2-aminoethanol. These results indicate that the toxicity is at least partly due to cyanamide, which is present in the toxic A. craccivora that infests R. pseudoacacia but absent from the non-toxic A. craccivora that infests V. angustifolia.

The substance is harmful to aquatic organisms. The substance may cause long-term effects in the aquatic environment. Avoid release to the environment in circumstances different to normal use.

2-Aminoethanol's production and use in hydraulic fracturing, as a gas scrubbing agent, as a dispersing agent for agricultural chemicals, as a pharmaceutics aid, as a component in polishes, hair waving solutions, emulsifiers and as a detergent used in dry cleaning and wool treatment may result in its release to the environment through various waste streams. 2-Aminoethanol has been identified as a constituents of mammalian and human urine. If released to air, a vapor pressure of 0.404 mm Hg at 25 °C indicates 2-aminoethanol will exist solely as a vapor in the atmosphere. Vapor-phase 2-aminoethanol will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 3.6 hours. 2-Aminoethanol does not contain chromophores that absorb at wavelengths >290 nm and, therefore, is not expected to be susceptible to direct photolysis by sunlight. If released to soil, 2-aminoethanol is expected to have very high mobility based upon an estimated Koc of 0.59. However, absorption is affected by the acidity of the soil. The pKa of 2-aminoethanol is 9.5, indicating that this compound will exist almost entirely in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts. Volatilization from moist soil is not expected because the compound exists as a cation and cations do not volatilize. 2-Aminoethanol is not expected to volatilize from dry soil surfaces based upon its vapor pressure. Using standard aerobic biodegradation tests employing activated sludge inoculum, 2-aminoethanol exhibited 64.4 to 91.4% CO2 consumption, suggesting that biodegradation is an important environmental fate process. This compound is considered to be readily biodegradable. If released into water, 2-aminoethanol is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. However, absorption is affected by the acidity of the substrate. A pKa of 9.5 indicates 2-aminoethanol will exist almost entirely in the cation form at pH values of 5 to 9 and, therefore, volatilization from water surfaces is not expected to be an important fate process. An estimated BCF of 3.2 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions (pH 5 to 9). Occupational exposure to 2-aminoethanol may occur through inhalation and dermal contact with this compound at workplaces where 2-aminoethanol is produced or used. Limited monitoring data indicate that the general population may be exposed to 2-aminoethanol via ingestion of food, use of tobacco products and dermal contact with consumer products containing 2-aminoethanol. (SRC)

A number of aliphatic amines have been identified as normal constituents of mammal and human urine, including ethanolamine(1).

2-Aminoethanol's production and use as a gas scrubbing agent, as a dispersing agent for agricultural chemicals, as a pharmaceutics aid, as a component in polishes, hair waving solutions, emulsifiers(1) and as a detergent used in dry cleaning and wool treatment(2) may result in its release to the environment through various waste streams(SRC).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 2-aminoethanol, which has a vapor pressure of 0.404 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 2-aminoethanol 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 3.6 hours(SRC), calculated from its rate constant of 3.6X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). 2-Aminoethanol does not contain chromophores that absorb at wavelengths >290 nm(4) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC).

AEROBIC: 2-Aminoethanol, present at 100 mg/L, reached 49.2% (nitrogen dioxide end product)and 93.6% (ammonia end product) of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 ppm in the Japanese MITI test(1). 2-Aminoethanol achieved 91.8% biodegradation after 28 days in a OECD Guideline 301B Sturm Test and 93.4% after 22 days in a Sealed vessel test(2). 2-Aminoethanol, present at 10 ppm, reached 34% of its theoretical BOD in 5 days and 40% of its theoretical BOD in 20 days using a sewage inoculum(3).

The rate constant for the vapor-phase reaction of 2-aminoethanol with photochemically-produced hydroxyl radicals has been estimated as 3.6X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 3.6 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). 2-Aminoethanol is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(2). 2-Aminoethanol does not contain chromophores that absorb at wavelengths >290 nm(2) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC).

An estimated BCF of 3.2 was calculated in fish for 2-aminoethanol(SRC), using a log Kow of -1.31(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). [

The Koc of 2-aminoethanol is estimated as 0.59(SRC), using a log Kow of -1.31(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 2-aminoethanol is expected to have very high mobility in soil. Adsorption can be affected by the acidity of the soil(SRC). The pKa of 2-aminoethanol is 9.5(4), indicating that this compound will exist almost entirely in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).

A pKa of 9.5(1) indicates 2-aminoethanol will exist almost entirely in the cation form at pH values of 5 to 9 and therefore volatilization from water surfaces and moist soil surfaces is not expected to be an important fate process(2). 2-Aminoethanol is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure of 0.404 mm Hg(3).

2-Aminoethanol was detected, not quantified in 24 Italian Cheeses(1). 2-Aminoethanol was detected in prune, plum, peach and nectarine juices at 1-6, 4, and 1 mg/L(2). 2-Aminoethanol has been identified as a meat volatile of chicken(3).

2-Aminoethanol is a component of tobacco(1,2).

According to the 2012 TSCA Inventory Update Reporting data, 10 reporting facilities estimate the number of persons reasonably likely to be exposed manufacturing, processing, or use of 2-aminoethanol in the United States may be as low as 10 workers and upwards to 499 workers per plant; the data may be greatly underestimated due to confidential business information (CBI) or unknown values(1).

NIOSH (NOES Survey 1981-1983) has statistically estimated that 1,163,087 workers (328,648 of these were female) were potentially exposed to 2-aminoethanol in the US(1). Occupational exposure to 2-aminoethanol may occur through inhalation and dermal contact with this compound at workplaces where 2-aminoethanol is produced or used. Limited monitoring data indicate that the general population may be exposed to 2-aminoethanol via ingestion of food, use of tobacco products and dermal contact with consumer products containing 2-aminoethanol(SRC).
