Environmental and breathing zone samples were analyzed for amines, aliphatic aldehydes, boron-trifluoride-monoethylamine (75230), epichlorohydrin (106898), total volatile fluorides, formaldehyde (50000), lead (7439921), methyl-tetrahydrophthalic-anhydride (26590205), and n-butyl-glycidyl-ether (2426086) at Electric Machinery/McGraw Edison Company (SIC-3621), Minneapolis, Minnesota in December, 1981 and February, 1983. The surveys were requested by the union local because of irritative symptoms and respiratory problems reported by employees exposed to epoxy resin compounds and impregnated materials. Medical questionnaires were administered to 51 employees in the hand taping and pole winding departments and 57 comparisons. Formaldehyde, acetaldehyde, and lead were the only contaminants detected. All concentrations were below their OSHA standards. Skin rash and irritation, eye irritation, and throat irritation were the most frequently reported symptoms. Fifty six percent of the exposed workers had evidence of carpal tunnel syndrome versus 7 percent of the comparisons. The authors conclude that mucous membrane irritation and dermatitis are common among workers exposed to epoxy resins. A high prevalence of carpal tunnel syndrome was also found. Recommendations include reducing formaldehyde concentrations, using personal protective equipment and barrier creams, and maintaining proper work practices and good personal hygiene to minimize contact with epoxy resin materials.
