In response to a request from the management of Computer Products Corporation (SIC-3571), Boulder, Colorado, an investigation was made of solvent exposures, after workers had complained of headaches and nausea. About 12 workers were employed at the site assembling circuit boards. Small components were cleaned manually by workers using cotton swabs wetted with isopropyl-alcohol (67630). One additional worker cleaned whole circuit boards in an open pan of the solvent for about 1 hour. Three other workers nearby in the potting department use cotton swabs wetted with acetone (67641) or 1,1,1- trichloroethane (71556). An 18 gallon tank of Humiseal Acrylic Coating containing mostly toluene (108883) and xylene (1330207) was also present for circuit board cleaning. Breathing zone air samples were collected from seven workers to evaluate solvent exposures. Solvent mixture exposures for six workers ranged from 7 to 15 percent of the combined evaluation criteria; one worker was exposed to 66 percent of the combined evaluation criteria. The author concludes that there were no exposures to solvents in excess of the recommended limits at the time of the visit. The author recommends that local exhaust ventilation be used during some of the procedures and that protective gloves be worn to reduce skin exposure to the sensitizers.
