Fresh air, rest. 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. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention .

May cause irritation and burns of eyes and skin. Exposure to excessive vapor concentrations can also cause drowsiness accompanied by nausea, headache, or extreme irritation of the respiratory tract. (USCG, 1999)

Immediate 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. /Esters and related compounds/

Use water spray to keep fire-exposed containers cool. Use fine spray or fog to control fire by preventing its spread and absorbing some of its heat. Solid streams of water may be ineffective or may cause frothing. Use water spray, dry chemical, foam, or carbon dioxide. Fight fire from protected location or maximum possible distance. /Ethyl acrylate, inhibited/

Special Hazards of Combustion Products: Toxic and irritating vapors generated when heated. Behavior in Fire: Vapor is heavier than air and may travel considerable distance to a source of ignition and flash back. May polymerize and cause container to explode. (USCG, 1999)

Wear self-contained breathing apparatus for firefighting if necessary.

Use 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.

Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Remove all ignition sources. Do NOT let this chemical enter the environment. 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.

SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.

Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.

Fireproof. Cool. Keep in the dark. Store only if stabilized.Store in away from heat, oxidizers, and sunlight. Outside or detached storage is preferred. Separate from any oxidizers, peroxides, or other initiators. /Ethyl acrylate, inhibited/

NIOSH recommends that ethyl acrylate be regulated as a potential occupational carcinogen.

NIOSH usually recommends that occupational exposures to carcinogens be limited to the lowest feasible concn.

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

Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).

Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.

Wear dust mask when handling large quantities.

Easily polymerizes on standing; polymerization process speeded up by heat, light, and peroxides. If pure, the monomer can be stored below +10°C without incurring polymerization.

Flammable liquid. A very dangerous fire hazard when exposed to heat or flame.The vapour mixes well with air, explosive mixtures are easily formed. Vapours are uninhibited and may polymerize, causing blockage of vents.A flammable liquid, confirmed carcinogen. It can react vigorously with oxidizing reagents, peroxides,strong alkalis and polymerization initiators. [NTP] It reacts violently with chlorosulfonic acid [Sax, 9th ed., 1996, p. 1515]. When an inhibited monomer was placed in a clear glass bottle exposed to sunlight, exothermic polymerization set in and caused the bottle to burst. The use of brown glass or metal containers and increase in inhibitor concentration (to 200 ppm; tenfold) was recommended [MCA Case History No. 1759]. It may polymerize when exposed to light and it is subject to slow hydrolysis. Inhibitors do not function in the absence of air. Solutions in DMSO are stable for 24 hours under normal lab conditions. [NTP].

NTP delisted ethyl acrylate as a suspected human carcinogen because the forestomach tumors in rats and mice appeared to arise from local tissue irritation and ulceration, rather than from a systemic toxicity, and occurred only at oral doses unlikely to be achieved by chronic human exposure. Ethyl acrylate remains an OSHA Select Carcinogen, due to its evaluation (Group 2B) by the IARC.

AEROBIC: Ethyl acrylate readily biodegrades in screening tests using sewage seed both in fresh and salt water(1). The percent of theoretical BOD is 28 and 11%, respectively, after 5 days; after acclimation, the BOD after 5 days increased to 66% of theoretical(1). Ethyl acrylate, present at 100 mg/L, reached 52% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(2). In three separate Zahn-Wellens tests, 60, 100, and >60% total organic carbon was removed in 3 hours, 7 days, and 11 days, respectively(3). Five day BOD for ethyl acrylate were 28, 66 and 11% in nonacclimated fresh dilution water, acclimated fresh dilution water and nonacclimated salt dilution water(3). The BOD5/COD ratio for ethyl acrylate was determined to be 0.77, which is indicative of significant potential for biodegradability(4).

An estimated BCF of 3 was calculated in fish for ethyl acrylate(SRC), using a log Kow of 1.32(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).

Koc values for ethyl acrylate have been reported as 4 in Washington clay/loam (29% sand, 42% silt, 29% clay, 3.39% organic carbon, pH 6.0), 23 in Canfield loam (45% sand, 42% silt, 13% clay, 4.58% organic carbon, pH 6.1), 40 in Ellsworth loam (35% sand, 40% silt, 25% clay, 1.42% organic carbon, pH 7.2), 85 in Tyner loamy sand (79% sand, 14% silt, 7% clay, 0.46% organic carbon, pH 5.2), and 81 in sandy loam sediment (53% sand, 28% silt, 19% clay, 1.23% organic carbon, pH 7.5)(1). According to a classification scheme(2), these Koc values suggest that ethyl acrylate is expected to have very high to high mobility in soil. Ethyl acrylate is highly soluble in water and, therefore, is not expected to partition to sediments(1).
