In response to a request from the management of Dale Electronics, Incorporated (SIC-3776), Norfolk, Nebraska, an evaluation was made of exposure to butyl-cellosolve (111762), epichlorohydrin (106898), nickel (7440020), chromium (7440473), antimony (7440360), and total particulates for workers in an electronic resistor manufacturing process. No exposure to butyl-cellosolve was detected among liquid coaters and no epichlorohydrin was detected in the process area air samples. No exposure to nickel or chromium was detected among mechanical grinding spirallers. One laser spiraller was exposed to 8 micrograms/cubic meter (microg/m3) of nickel and 8microg/m3 chromium. Trace amounts of nickel were noted in the breathing zones of one plating lab worker and one calibrator. Total particulate exposures ranged from 0.1 to 0.9mg/m3. The author concludes that there were no known overexposures to contaminants at this facility. The author recommends that the exhaust ducts and fan be checked to find the cause for decreased mixing room ventilation system performance noted at the time of the study. Mixing room workers should ensure that all materials are handled as closely as possible to the local exhaust hoods. Standard written operation procedures for use of respirators should be developed.
