HHE Report No. HETA-82-127-1370, Hoover Company Industrial Park, North Canton, Ohio.
Exposures to organic solvents, pigments, and other chemicals were surveyed at Hoover Company Industrial Park (SIC-3630), North Canton, Ohio in June 1982. Evaluation was requested by the International Brotherhood of Electrical Workers, Local 1985, on behalf of 600 workers. Air samples were analyzed for methyl-ethyl-ketone (78933), toluene (108883), xylene (1330207), petroleum-naphtha (8030306), butyl-cellosolve (111762), butyl-acetate (123864), vinyl-chloride (75014), di(2-ethylhexyl)phthalate (117817), formaldehyde (50000), cadmium (7440439) and nickel (7440020) pigments, and respirable particulates. Urine and blood samples were collected to evaluate exposures to methyl-ethyl-ketone, toluene, xylene, and cadmium. Concentrations of all substances were within OSHA standards for individual and combined exposures. The mean end of shift blood methyl-ethyl-ketone concentration was 1.2 micrograms per liter. Preshift to postshift increases in urinary hippuric-acid were greater for workers exposed to toluene compared to unexposed workers. Only 1 of 27 workers tested had detectable amounts of urinary methyl-hippuric-acid. No urinary cadmium was found. The authors conclude that environmental exposure hazards exist at this facility; however, some workers appear to be absorbing organic solvents. Due to the carcinogenic potential of formaldehyde and di(2-ethylhexyl)phthalate, exposures should be eliminated or kept to the lowest feasible limit. Improved ventilation, use of respirators, and good work practices are recommended.
