2.11 Carcinogenicity

Ethyl acetate was not mutagenic in bacterialassays; it was not genotoxic in a numberof in vivo assays but did cause chromosomaldamage in hamster cells in vitro.Ethyl acetate has a fruity odor detectableat 10ppm.The 2003 ACGIH threshold limit valuetime-weighted average (TLV-TWA) for ethylacetate is 400pm (1440mg/m3).

2.12 Chemical Properties

Ethyl acetate (structure shown above) is the most familiar ester to many chemistry students and possibly the ester with the widest range of uses. Esters are structurally derived from carboxylic acids by replacing the acidic hydrogen by an alkyl or aryl group. Ethyl acetate itself is a colourless liquid at room temperature with a pleasant “fruity” smell, b.p. 77°C.

2.13 Physical Properties

Clear, colorless, mobile liquid with a pleasant, sweet fruity odor. Experimentally determineddetection and recognition odor threshold concentrations were 23 mg/m3 (6.4 ppmv) and 48 mg/m3(13.3 ppmv), respectively (Hellman and Small, 1974). Cometto-Mu?iz and Cain (1991) reportedan average nasal pungency threshold concentration of 67,300 ppmv.

4.3 Other Preventative Measures

USE EFFECTIVE FUME REMOVAL DEVICE /IN LABORATORY/.
Employees should wash promptly when skin is wet or contaminated. Remove clothing immediately if wet or contaminated to avoid flammability hazard.
Avoid breathing vapors. Keep upwind. Wear appropriate chemical protective gloves, boots and goggles. Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water.
