ing operations involvig the use of a bisphenol-A diglycidyl ether tye of epoxy resin. ln a faciity producig miltaiy aircraft, the use of an epoxy prier did not result in detectable epoxide levels, and the authors surmised that the epoxy-amine curig reaction had probably . consumed most of the epoxide group. Epoxide levels of 2-12 J.Eq/m3 epode functional group were recorded durig the painting of a tank with col-tar epoxy coatings and the painting of a metal ceiling using an epoxy architectural coating (Herrck et al., 1988). ln a US company that finished structural steel members and other fabricated steel products, the products are blasted with steel shot or sand and spray-painted with two-mponent epoxy paints or oil-based paints. Personal air levels of epichlorohydri were reported to range from 2.4 to 138.9 mg/m3, with a mean 1W A of 64.9 mg/m3. Bisphenol A glycidyl ethers were also detected in the workers' breathing zone at levels which ranged from below the limit of detection (0.6 J.g) to 28.6 J.g/m3, with a mean of 9.8 J.g/m3 (Chrostek & Levie, 1981).
