Personal and environmental sampling was conducted, visual observations were made, and employees were interviewed to investigate possible toxic exposures at Dover Molded Products, Incorporated, (SIC-3079), Dover, Ohio on March 21 and 22, 1979. An authorized representative of the approximately 80 affected employees requested the evaluation. Samples analyzed for lead (7439921), chromium (7440473), cadmium (7440439), 1,1,1-trichloroethane (71556), Freon-11 (75694), and Freon-12 (75718) were within OSHA criteria of 0.05 milligrams per cubic meter (mg/cu m), 0.5mg/cu m, respectively. The authors conclude that 2 employees, the color blender and the hopper filler, were exposed to concentrations of heavy metals above the recommended maximum levels. Other employees periodically were exposed to irritant substances. NIOSH recommends that the use of colorants containing chromium and cadmium be phased out; respirators be supplied and worn by the color blender and the hopper filler as long as these metals are used; job rotation be arranged so that an individual is not working on vinyl plastic and silicone molds continuously; smoking, eating and drinking be prohibited in the manufacturing portion of the facility; and press hoppers be refilled only when the operator is not in attendance.
