Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.

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

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer 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)

IDENTIFICATION AND USE: Triethylamine (TEA) is a colorless liquid. It is used as catalytic solvent in chemical synthesis; accelerator activators for rubber; wetting, penetrating, and waterproofing agents of quaternary ammonium types; curing and hardening of polymers; corrosion inhibitor; propellant. HUMAN EXPOSURE AND TOXICITY: Aside from irritation of the eyes and respiratory tract, triethylamine also stimulates the central nervous system, because it inhibits monamine oxidase. Experimental studies were conducted in four healthy men on the metabolism of inhaled TEA (20 mg/cu m) with and without ethanol ingestion. Three subjects displayed visual disturbances in the experiments without ethanol. These same subjects did not experience any visual disturbances in those experiments containing ethanol. In another study, four hour exposure to a TEA concentration of 3.0 mg/cu m seemed to cause no effects, whereas exposure to 6.5 mg/cu m for the same period caused blurred vision and a decrease in contrast sensitivity. Two volunteers were exposed to various airborne concentrations of triethylamine. Levels of 18 mg/cu m for eight hours caused subjective visual disturbances (haze and halos) and objective corneal edema. The effects faded within hours after the end of exposure. A cross-sectional study of visual disturbances was conducted in 19 workers (13 men, 6 women, mean age 45) employed in a polyurethane foam production plant. Visual disturbances (foggy vision, blue haze, and sometimes halo phemomena) were reported by 5 workers. Symptoms were associated with work operations with the highest exposure to triethylamine (TWA= 12-13 mg/cu m). ANIMAL STUDIES: TEA irritates the mucous membranes and the respiratory tract. In concentrations of 156 ppm a 50% decrease of the respiratory rate in rats was found. A 70% solution applied on the skin of guinea pigs caused prompt skin burns leading to necrosis; when held in contact with guinea pig skin for 2 hr, there was severe skin irritation with extensive necrosis and deep scarring. Five cat eyes and 1 monkey eye were exposed to triethylamine. Animals were exposed to triethylamine at rates of 0.45-0.85 mmol triethylamine/5 min for periods ranging from 1 to 5 min. Corneal epithelial damage occurred at all doses and was severe at higher concentrations. In all cases the epithelium was healed by day 4. Optical discontinuities of the stroma similar to those seen in human patients were observed at all dose levels. Convulsions observed in all rats given oral dosages of 50 mg or more. Triethylamine was tested on 3 day old chicken embryos. Malformations observed were: small eye cup 31%, defects of lids and cornea 73%, defects of beak 4%, encephalocoele or skin pimple in head 23%, open coelom 35%, short back or neck 42%, defects of wings 38%, and edema and lymph blebs 4%. Triethylamine was tested for mutagenicity in the Salmonella/microsome preincubation assay. Triethylamine was tested at doses of 0, 100, 333, 1000, 3333, and 10,000 ug/plate in four Salmonella typhimurium strains (TA98, TA100, TA1535, and TA1537) in the presence and absence of metabolic activation. Triethylamine was negative in these tests.

Employee who /will be/ exposed to triethylamine at potentially hazardous levels should be screened for history of certain medical conditions /chronic respiratory diseases, cardiovascular diseases, liver diseases, kidney diseases, eye diseases/ which might place the employee at increased risk from triethylamine exposure. Any employee developing the conditions should be referred for further medical exam.

/HUMAN EXPOSURE STUDIES/ Experimental studies were conducted in four healthy men on the metab of inhaled triethylamine (TEA) (20 mg/cu m) with and without ethanol ingestion. The mean serum ethanol concn during exposure & in the first hr after exposure was 25 mmol/L, ranging from 16 to 35 mmol/L. TEA was readily absorbed during exposure & partly oxygenated into triethylamine-N-oxide. The concn in plasma of TEA at the end of the exposure were lower in experiments with ethanol intake. TEA plus ethanol plus sodium bicarbonate caused the highest plasma levels, with only minor TEA amounts exhaled. The half live of TEA in urine was similar in many experiments. The triethylamine-N-oxide excretion was lower after ethanol ingestion than after exposure to TEA alone. Urinary pH profoundly affected TEA metabolism. /SRP: A decrease of the urinary pH by one increased renal clearance of TEA by a factor of 2./A change in urinary pH by about 2 units caused a change of renal clearance of TEA by a factor of three & of the oxygenation by a factor of two. Renal clearance of triethylamine-N-oxide was not affected by urinary pH. Three subjects displayed visual disturbances in the experiments without ethanol. These same subjects did not experience any visual disturbances in those experiments containing ethanol. It was concluded that, theoretically, the ethanol intake & varying urinary pH may affect the possibility of monitoring TEA exposure through biological samples. Although there was good correlation between air TEA levels & either end shift plasma levels & post shift urinary excretion of TEA plus triethylamine-N-oxide in an industrial settling, a determination of urinary pH would help.

/HUMAN EXPOSURE STUDIES/ In 20 workers studied before, during, and after exposure to triethylamine (TEA) in a polyurethane-foam producing plant the amount of TEA and its metabolite triethylamine-N-oxide (TEAO) excreted in urine corresponded to an average of 80% of the inhaled amount. An average of 27% was TEAO, but with a pronounced interindividual variation. Older subjects excreted more than younger ones; less than 0.3% was excreted as diethylamine.

/HUMAN EXPOSURE STUDIES/ ... Four people were exposed to triethylamine (TEA) for 4 hr at concentrations of 40.6, 6.5, and 3.0 mg/cu m. Before and after every exposure, symptoms and ocular microscopy findings were recorded. Binocular visual acuity and contrast sensitivity at 2.5% contrast were also measured. Also, before and after the 40.6 mg/cu m exposure, corneal thickness was measured and ocular dimensions were recorded by ultrasonography, endothelial cells of the cornea were analyzed, and serum and lacrimal specimens were collected for the analysis of TEA. After exposure to 40.6 mg/cu m TEA there was a marked edema in the corneal epithelium and subepithelial microcysts. However, corneal thickness increased only minimally because of the epithelial edema. The lacrimal concentrations of TEA were, on average (range) 41 (18-83) times higher than the serum TEA concentrations. The vision was blurred in all subjects and visual acuity and contrast sensitivity had decreased in three of the four subjects. After exposure to TEA at 6.5 mg/cu m two subjects experienced symptoms, and contrast sensitivity had decreased in three of the four subjects. There were no symptoms or decreases in contrast sensitivity after exposure to a TEA concentration of 3.0 mg/cu m. TEA caused a marked edema and microcysts in corneal epithelium but only minor increases in corneal thickness. The effects may be mediated by the lacrimal fluid owing to its high TEA concentration. Four hour exposure to a TEA concentration of 3.0 mg/cu m seemed to cause no effects, whereas exposure to 6.5 mg/cu m for the same period caused blurred vision and a decrease in contrast sensitivity.

/HUMAN EXPOSURE STUDIES/ Two volunteers were exposed to various airborne concentrations of triethylamine. Levels of 18 mg/cu m for eight hours caused subjective visual disturbances (haze and halos) and objective corneal edema. The effects faded within hours after the end of exposure.

/LABORATORY ANIMALS: Acute Exposure/ Rats exposed at 500 ppm for 4 hours survived; 1000 ppm was fatal to one of six, and 2000 ppm killed all six test rats. No deaths were produced in guinea pigs exposed at up to 2000 ppm for 30 minutes. Four of six exposed animals died following a 2- hour exposure at 2000 ppm; two of six died following a 4-hour exposure at 1000 ppm; however, all six exposed animals survived a 4-hour exposure at 250 ppm.

/LABORATORY ANIMALS: Acute Exposure/ /Triethylamine/ is strongly alkaline, and when drop is applied to rabbit's eye, causes severe injury, graded 9 on scale of 1 to 10 after 24 hr /most severe injuries have been rated 10/. Tests of aqueaous solution on rabbit eyes at pH 10 and pH 11 indicate injuriousness /of triethylamine/ is related principally to degree of alkalinity.

/LABORATORY ANIMALS: Acute Exposure/ A 70% soln applied on the skin of guinea pigs caused prompt skin burns leading to necrosis; when held in contact with guinea pig skin for 2 hr, there was severe skin irritation with extensive necrosis and deep scarring.

/LABORATORY ANIMALS: Acute Exposure/ ... Five cat eyes and 1 monkey eye were exposed to triethylamine. Animals were exposed to triethylamine at rates of 0.45-0.85 mmol triethylamine/5 min for periods ranging from 1 to 5 min. Corneal epithelial damage occurred at all doses and was severe at higher concentrations. In all cases the epithelium was healed by day 4. Optical discontinuities of the stroma similar to those seen in human patients were observed at all dose levels.

The substance is harmful to aquatic organisms.

Triethylamine's production and use as a solvent, catalyst, binding resin and chemical intermediate may result in its release to the environment through various waste streams. If released to air, a vapor pressure of 57.07 mm Hg at 25 °C indicates triethylamine will exist solely as a vapor in the atmosphere. Vapor-phase triethylamine 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 4.2 hours. Triethylamine 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, triethylamine is expected to have high mobility based upon an estimated Koc of 51. The pKa of triethylamine is 10.78, indicating that this compound will exist almost entirely in 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. Triethylamine may volatilize from dry soil surfaces based upon its vapor pressure. Utilizing the Japanese MITI test, 28% of the Theoretical BOD was reached in 4 weeks indicating that biodegradation may be an important environmental fate process in soil and water. If released into water, triethylamine is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's pKa. BCFs of <4.9 measured in carp suggest 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 triethylamine may occur through inhalation and dermal contact with this compound at workplaces where triethylamine is produced or used. Monitoring data indicate that the general population may be exposed to triethylamine via inhalation of tobacco smoke and ambient air, ingestion of food, and dermal contact with consumer products containing triethylamine.

Triethylamine's production and use in the synthesis of semisynthetic penicillins and cephalosporins, as a polyurethane catalysts, an anti-corrosion agent, in paper, textile and photographic auxiliaries, and in anodic electro-coating(1) may result in its release to the environment through various waste streams(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 51(SRC), determined from a structure estimation method(2), indicates that triethylamine is expected to have high mobility in soil(SRC). The pKa of triethylamine is 10.78(3), indicating that this compound will exist almost entirely in cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization of the cation from moist soil is not expected because cations do not volatilize(SRC). Triethylamine is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 57.07 mm Hg at 25 °C(3). A 28% of Theoretical BOD using activated sludge in the Japanese MITI test(5) suggests that biodegradation may be an important environmental fate process in soil(SRC).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 51(SRC), determined from a structure estimation method(2), indicates that triethylamine is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected based upon a pKa of 10.78(3), indicating that triethylamine will exist almost entirely in the cation form and cations do not volatilize(SRC). Triethylamine is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(4). According to a classification scheme(5), BCFs of <4.9(6), suggest bioconcentration in aquatic organisms is low. Triethylamine present at 100 mg/L, reached 28% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(6).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), triethylamine, which has a vapor pressure of 57.07 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase triethylamine 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 4.2 hours(SRC), calculated from its rate constant of 9.3X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Triethylamine 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: Triethylamine was not degraded by activated sludge even when acclimatized (BOD 5.3% of theoretical after 13 days)(1). Triethylamine, present at 100 mg/L, reached 28% of its Theoretical BOD in 4 weeks using an activated sludge inoculum at 100 mg/L in the Japanese MITI test(2). [

ANAEROBIC: Triethylamine was found to be persistent under anaerobic conditions(1).

The rate constant for the vapor-phase reaction of triethylamine with photochemically-produced hydroxyl radicals has been estimated as 9.3X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 4.2 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). Triethylamine is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(2). Triethylamine 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). Experiments show that triethylamine reacts with NO-NO2-H20 mixtures to form diethylnitroamine both in the dark and on irradiation(3). On irradiation, triethylamine is highly reactive forming ozone, PAN, acetaldehyde, diethylnitroamine, diethylformamide, ethylacetamide, and diethylacetamide and aerosols(3). These experiments were performed in large outdoor chambers under natural conditions of temperature, humidity, and illumination(3). Initially the mixture was allowed to react for two hours in the dark and then exposed to sunlight. The triethylamine completely disappeared after 90 minutes of illumination(3).

Measured BCF values of <0.5 and <4.9 were reported in carp (Cyprinus carpio; lipid content, 3.9%), exposed to triethylamine at 0.5 and 0.05 mg/L, respectively, over a 6-week period(1). According to a classification scheme(2), these BCFs suggest the potential for bioconcentration in aquatic organisms is low(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of triethylamine can be estimated to be 51(SRC). According to a classification scheme(2), this estimated Koc value suggests that triethylamine is expected to have high mobility in soil. The pKa of triethylamine is 10.78(3), 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(4).

A pKa of 10.78(1) indicates triethylamine will exist almost entirely in the cation form at pH values of 5 to 9. Volatilization from water and moist soil surfaces is not expected to be an important environmental fate because cations do not volatilize(SRC). Triethylamine is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 57.07 mm Hg(1).

Triethylamine has been reported in an effluent sample from the plastics and synthetics industry at 356.5 mg/L(1). It is emitted from sewage treatment plants(2). Anthropogenic releases of triethylamine by industry in the US to the atmosphere, surface water, underwater injections, land, and off-site were 2.3X10+5, 2299, 1.3X10+5, 10, and 2961 lbs, respectively, for the year 2014(3).

SOIL: Triethylamine was identified in uncultivated loamy soil from the Moscow, Russia region. Since this soil is uncultivated, it is possible that the amines are formed naturally rather than being a contaminant or a metabolite of a fertilizer or pesticide(1).

URBAN/SUBURBAN: The ambient concentration of triethylamine in air at one urban location in the US ranged from not detected to 4 ug/cu m(1). Ambient air sampled from coastal and residential areas of Southern Sweden in 1991 contained <0.2 ng/cu m of triethylamine(2). Trace levels (ca 2-10 pmol/cu m) of triethylamine were detected in air in Sweden urban areas of Lund, Sodra, and Vallby(3).

INDOOR: Triethylamine was detected at 11.9-16.5 and 15.8 ug/cu m in the interior of a motor vehicle using direct and diffusive sampling after heating 6 hours at 40 °C for 3 days. After 7 days results were 37.3 and 11.7 ug/cu m using direct and diffusive sampling, respectively(1).

RURAL/REMOTE: Ambient air sampled from a rural area of Southern Sweden in 1991 contained 0.2-2 ng/cu m trimethylamine(1).

SOURCE DOMINATED: In 1983, triethylamine was detected in an unspecified location (suspected industrial facility) in the United States at <4.2 ug/cu m(1).

Triethylamine has been identified as a volatile component of boiled beef(1).
