Fire Extinguishing Agents: Water, carbon dioxide, or dry chemical (USCG, 1999)

Use water spray, powder, alcohol-resistant foam, carbon dioxide.

Fresh air, rest.

Remove contaminated clothes. Rinse skin with plenty of water or shower.

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

Rinse mouth.

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.

Wear self contained breathing apparatus for fire fighting if necessary.

Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.

Use water spray to cool unopened containers.

Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Store under inert gas. Hygroscopic.

STORAGE: Protect from ignition sources. Keep tanker or tote tightly closed. Do not store in a manner that might adversely effect tote or tanker's integrity. /Phillips Fuel Additive 56 MB/

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.

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.

Prevent further leakage or spillage if safe to do so. Do not let product enter drains.

SMALL SPILLS AND LEAKAGE: If you should spill this chemical, use absorbent paper to pick up all liquid spill material. Seal the absorbent paper, as well as any of your clothing which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Wash any surfaces you may have contaminated with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination. 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 soil or water; effects on animal and plant life; and conformance with environmental and public health regulations.

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 monomethyl ether is expected to have very high mobility in soil(SRC). Volatilization of diethylene glycol monomethyl ether from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.6X10-11 atm-cu m/mole(SRC), using a fragment constant estimation method(2). Diethylene glycol monomethyl ether is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.25 mm Hg at 25 °C(3). Aqueous screening test data suggest that biodegradation may be an important removal mechanism of diethylene glycol monomethyl ether in soil: theoretical BOD losses of 0, 21 and 66% when incubated at 20 °C for 5, 10 and 20 days, respectively, were reported(4).

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 monomethyl ether 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 1.6X10-11 atm-cu m/mole(SRC), developed using a fragment constant estimation method(2). Diethylene glycol monomethyl ether is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(3). According to a classification scheme(4), an estimated BCF of 3(SRC), from an estimated log Kow of -1.18(2) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Aqueous screening test data suggest that biodegradation may be an important removal mechanism of diethylene glycol monomethyl ether: theoretical BOD losses of 0, 21 and 66% when incubated at 20 °C for 5, 10 and 20 days, respectively, were reported(5).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), diethylene glycol monomethyl ether, which has a vapor pressure of 0.25 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase diethylene glycol monomethyl ether 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 13 hours(SRC), calculated from its rate constant of 2.6X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Alcohols and ethers do not contain chromophores that absorb at wavelengths >290 nm(4) and, therefore, diethylene glycol monomethyl ether is not expected to be susceptible to direct photolysis by sunlight(SRC).

From a National Survey, diethylene glycol monomethyl ether was detected in 1 of 21 industrial categories of wastewater effluents(1). Wastewater from the paint and ink industries contained diethylene glycol monomethyl ether at an average of 3,571 mg/L(1). Diethylene glycol monomethyl ether was listed as a volatile emission of glycol ether production(2). Diethylene glycol monomethyl ether was detected, not quantified, in 2 of 44 emission samples from furniture(3). Diethylene glycol monomethyl ether was found as a volatile given off of paint removers(4-5) and in disperse colorants(5).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of diethylene glycol monomethyl ether can be estimated to be 1(SRC). According to a classification scheme(2), this estimated Koc value suggests that diethylene glycol monomethyl ether is expected to have very high mobility in soil.

The in vitro absorption of 2-(2-methoxyethoxy)ethanol through human skin was evaluated. The test substance as a neat liquid was left in contact with the skin for approximately 8 hours. Within 1 hour of skin contact a steady rate of penetration was observed. The mean steady rate of absorption for 2-(2-methoxyethoxy)ethanol was 0.21mg/cm(2)/hour. No significant irreversible alterations to the barrier properties of the epidermal /layer/ were observed.

Acute oral toxicity was evaluated in 4 groups of 10 male albino Wistar rats administered single doses of Poly Solv DM (diethylene glycol monomethyl ether) by gavage at dose levels of 5.0, 7.12, 10.14, and 14.43 g/kg. One mortality was observed at the 10.14 g/kg dose level and 3 mortalities were observed at the 14.43 g/kg dose level within 14 days of dosing. The LD50 was calculated to be greater than 14.43 g/kg (95% confidence), using the Litchfield and Wilcoxon method. Clinical observations include piloerection at the 7.12 g/kg dose level and slight lethargy at both higher dose levels. Gross necropsy revealed dark lungs at the 5.0, 7.12 and 10.14 g/kg dose levels; red intestines at the 10.14 and 14.43 g/kg dose levels; mottled liver at the 5.0 and 7.12 g/kg dose levels; dark and enlarged spleen at the 5.0 g/kg dose level.

Acute oral toxicity was evaluated using 5 groups of 5 Charles River COBS male rats administered diethlyene glycol monomethyl ether by gavage (dose levels not reported). Mortality occurred within 14 days after dosing, but the LD50 value was not reported. Clinical observations included inactivity, labored breathing, rapid respiration, anorexia, slight to moderate weakness, tremors and prostration. Gross necropsy of animals dying within 14 days of dosing revealed bloody urine, and blood in the stomach and intestine. These conditions were not observed in animals surviving through 14 days.

/CASE REPORTS/ Retrocaval ureter is a very rare condition. In light of the experimental studies, one of the etiologic factors seems to be maternal contact with diethylene glycol monomethyl ether or ethylene glycol monomethyl ether. A case of cardiovascular, skeletal, and retrocaval ureter anomalies caused by possible maternal contact while pregnant with these materials at her work in a textile factory is presented.

/SURVEILLANCE/ /The aim is/ to study health effects in hospital cleaners (N = 21) at floor polish removal and application. The cleaners were investigated before exposure (Monday = day 1), after polish removal work (day 2), and after application of floor polish (day 3). Ratings of symptoms, tear-film break-up-time (BUT), nasal patency and biomarkers in nasal lavage were studied. There was a significant increase both day 2 and day 3, as compared to pre-exposure, in ocular, nasal, throat symptoms, solvent smell, dyspnea, and general symptoms such as headache and fatigue. Posterior nasal patency was decreased day 2 (p < 0.01) and day 3 (p < 0.01). No change of nasal biomarkers (eosinophil cationic protein (ECP), myeloperoxidase (MPO), lysozyme, albumin) was seen. BUT was decreased after polish removal (p < 0.01), but not after polish application. Separate test of the weekday effect in non-exposed showed slight improvements, or no change of symptoms or clinical signs from Monday to Wednesday. Air concentrations of ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, diethylene glycol monoethyl ether, dipropylene glycol monomethyl ether, diethylene glycol monoethyl ether and ethylene glycol phenyl ether 103, 666, 13,650, 7,000, 67, and 27 ug/cu m, respectively, at polish application. Glycol ether levels were reduced to 3% after 2 days and 0.3% after 17 days. Emissions from a common water-based polish remover and floor polish system may cause ocular and airway irritation and general symptoms, and reduce tear-film stability and nasal patency. The levels of glycol ethers had a rapid decay.

This action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. Diethylene glycol monomethyl ether is produced, as an intermediate or final product, by process units covered under this subpart.

...Male Sprague-Dawley rats were given 0.051, or 5.1 mmol/kg (14)C labeled bis(2-methoxyethyl)ether orally. The principal urinary metabolites were (2-methoxyethoxy)acetic acid and methoxyacetic acid which accounted for around 70 and 6% of the doses, respectively. Smaller amounts of N-(methoxyacetyl)glycine, diglycolic acid, 2-methoxyethanol, and 2-(2-methoxyethoxy)ethanol were found. Only unchanged bis(2-methoxyethyl)ether was found in the volatile organic fraction of the expired air. ...Bis(2-methoxyethyl)ether metabolism proceeds primarily through an O-demethylation pathway, followed by oxidation to (2-methoxyethoxy)acetic acid. The lack of toxicity of 2-(2-methoxyethoxy)ethanol and (2-methoxyethoxy)acetic acid suggests that the testicular toxicity of bis(2-methoxyethyl)ether may be due to methoxyacetic acid, a minor metabolite.

... /It is/ absorbed by skin ... .

... Material can be absorbed through skin of rabbits in toxic amounts... .

To assist evaluation of the hazards of skin contact with selected undiluted glycol ethers, their absorption across isolated human abdominal epidermis was measured in vitro. Epidermal membranes were set up in glass diffusion cells and, following an initial determination of permeability to tritiated water, excess undiluted glycol ether was applied to the outer surface for 8 hr. The appearance of glycol ether in an aqueous receptor phase bathing the underside of the epidermis was quantified by a gas chromatographic technique. A final determination of tritiated water permeability was compared with initial values to establish any irreversible alterations in epidermal barrier function induced by contact with the glycol ethers. 2-methoxyethanol (EM) was most readily absorbed (mean steady rate 2.82 mg/sq cm/hr), and a relatively high absorption rate (1.17 mg/sq cm/hr) was also apparent for 1-methoxypropan-2-ol (PM). There was a trend of reducing absorption rate with increasing molecular weight or reducing volatility for monoethylene glycol ethers (EM, 2.82 mg/sq cm/hr; 2-ethoxyethanol, EE, 0.796 mg/sq cm/hr; 2-butoxyethanol, EB, 0.198 mg/sq cm/hr) and also within the diethylene glycol series: 2-(2-methoxyethoxy) ethanol (DM, 0.206 mg/sq cm/hr); 2-(2-ethoxyethoxy) ethanol (DE, 0.125 mg/sq cm/hr) and 2-(2-butoxyethoxy) ethanol (DB, 0.035 mg/sq cm/hr). The rate of absorption of 2-ethoxyethyl acetate (EEAc) was similar to that of the parent alcohol, EE. Absorption rates of diethylene glycol ethers were slower than their corresponding monoethylene glycol equivalents. Combination of intrinsic toxicity and ability to pass across skin contribute to assessment of hazards of contact with undiluted glycol ethers.

The toxicity of bis(2-methoxyethyl)ether was studied in rats. Male Sprague-Dawley rats were given 0.051, or 5.1 mmol/kg (14)C labeled bis(2-methoxyethyl)ether orally. The principal urinary metabolites were (2-methoxyethoxy)acetic acid and methoxyacetic acid which accounted for around 70 and 6% of the doses, respectively. Smaller amounts of N-(methoxyacetyl)glycine, diglycolic acid, 2-methoxyethanol, and 2-(2-methoxyethoxy)ethanol were found. Only unchanged bis(2-methoxyethyl)ether was found in the volatile organic fraction of the expired air. Additionally, rats were given up to 20 daily doses of 5.1 mmol/kg 2-(2-methoxyethoxy)ethanol or (2-methoxyethoxy)acetic acid at on days 3 through 21. 2-(2-Methoxyethoxy)ethanol and (2-methoxyethoxy)acetic acid induced no gross or histopathological testicular changes. Bis(2-methoxyethyl)ether metabolism proceeds primarily through an O-demethylation pathway, followed by oxidation to (2-methoxyethoxy)acetic acid. The lack of toxicity of 2-(2-methoxyethoxy)ethanol and (2-methoxyethoxy)acetic acid suggests that the testicular toxicity of bis(2-methoxyethyl)ether may be due to methoxyacetic acid, a minor metabolite.
