  Ethyl Acetate
Ethyl acetate is a clear, colorless, flammable liquid with a pleasant, fruity odor.
The oral LD(50) for acute exposure to ethyl acetate is 4,935 mg/kg for rabbits and 5,620 mg/kg for rats; and the 8-hour rat inhalation LC(50) is 1600 ppm [Sax and Lewis 1989].
Containers of ethyl acetate should be protected from physical damage and ignition sources, and should be stored separately from nitrates, strong oxidizers, strong alkalies, or strong acids, chlorosulfonic acid, lithium aluminum hydride, 2-chloromethyl furan, oleum, and potassium t-butoxide.

  HHMI Lab Safety: LCSS: ETHYL ACETATE   (Site not responding. Last check: )
Ethyl acetate is a flammable liquid (NFPA rating = 3), and its vapor can travel a considerable distance to an ignition source and "flash back." Ethyl acetate vapor forms explosive mixtures with air at concentrations of 2 to 11.5% (by volume).
Ethyl acetate should be handled in the laboratory using the "basic prudent practices" described in Chapter 5.C, supplemented by the additional precautions for dealing with highly flammable substances (Chapter 5.F).
In particular, ethyl acetate should be used only in areas free of ignition sources, and quantities greater than 1 liter should be stored in tightly sealed metal containers in areas separate from oxidizers.
