Section IV.        First Aid Measures    
    Eye Contact        Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15    
    minutes. Get medical attention.
    Skin Contact        In case of contact, immediately flush skin with plenty of water. Remove contaminated clothing and shoes. Wash clothing    
    before reuse. Thoroughly clean shoes before reuse. Get medical attention.
    Inhalation        If the victim is not breathing, perform mouth-to-mouth resuscitation. Loosen tight clothing such as a collar, tie, belt or    
    waistband. If breathing is difficult, oxygen can be administered. Seek medical attention if respiration problems do not
    improve.
    Ingestion        INDUCE VOMITING by sticking finger in throat. Lower the head so that the vomit will not reenter the mouth and throat.    
    Loosen tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing, perform mouth-to-mouth
    resuscitation. Examine the lips and mouth to ascertain whether the tissues are damaged, a possible indication that the
    toxic material was ingested; the absence of such signs, however, is not conclusive.

Section XII.        Ecological Information    
    Ecotoxicity        Not available.    
    Environmental Fate        soluble at lowe    
    Ethyl acetate's production and use as a pharmaceutic aid, in artificial fruit essences, and as a solvent may result in its
    release to the environment through various waste streams. If released to air, a vapor pressure of 93 mm Hg at 25 deg C
    indicates ethyl acetate will exist solely as a vapor in the ambient atmosphere. Vapor-phase ethyl acetate 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 9.4 days. If released to soil, ethyl acetate is expected to have high mobility based upon an estimated Koc
    of 59. Volatilization from moist soil surfaces is expected to occur based upon a Henry's Law constant of 1.34X10-4 atm-cu
    m/mole. Ethyl acetate's vapor pressure indicates the potential for volatilization from dry soil surfaces exists.
    Biodegradation is expected to be an important process in both soil and water, based upon ethyl acetate's biodegradation
    in aqueous screening studies. 93% biodegradation was observed in a complete mix continuous-flow activated sludge
    system. 26.6 and 57.1% of ethyl acetate's theoretical BOD was reached in 5 days using the standard dilution method and
    seawater dilution method, respectively. If released into water, ethyl acetate is not expected to adsorb to suspended solids
    and sediment in water based on the estimated Koc. Volatilization from water surfaces is expected to be an important fate
    process based on ethyl acetate's Henry's Law constant. Estimated volatilization half-lives for a model river and model lake
    are 8.9 hours and 5.6 days, respectively. An estimated BCF of 3.2 suggests the potential for bioconcentration in aquatic
    organisms is low. Ethyl acetate's hydrolysis half-life at 25 deg C and pH 7 is 2.0 years. Occupational exposure to ethyl
    acetate may occur through inhalation and dermal contact with this compound at workplaces where ethyl acetate is
    produced or used or where adhesives, thinners, degreasers, paints, inks, and dome reagents are used. The general
    population may be exposed to ethyl acetate via inhalation of ambient air, ingestion of food and drinking water, or dermal
    contact with consumer products containing this compound.

Section XIII. Disposal Considerations
    Waste Disposal        Recycle to process, if possible. Consult your local regional authorities. You may be able to dissolve or mix material with a    
    combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber system. Observe all
    federal, state and local regulations when disposing of the substance.
