In response to a confidential employee request, an investigation was begun of worker exposures to airborne contaminants and the effectiveness of the ventilation system at JMS Southeast, Inc. (SIC- 3823), Statesville, North Carolina. The company employed 42 workers, including 17 directly involved in manufacturing temperature measurement devices for industrial applications. Processes evaluated at this site during the on site visit included tungsten inert gas welding (TIG), metal grinding, buffing and sanding, brazing and soldering, and degreasing. Observations included sporadic adherence to the use of personal protective equipment and the lack of a formal safety program. Shop vacuums were used to ventilate the grinders and tubing cutters and did not appear to effectively contain the dusts after collection. Air sampling results indicated that contaminant levels were below NIOSH recommended exposure limits. Low concentrations of metals, both fumes and dust, were detected at several workstations. The author concludes that workers were not exposed to airborne contaminants above recommended limits at the time of the survey. The shop vacuums used as local exhaust systems were not intended for this use. The author recommends specific measures to improve the level of safety and health, including ventilation and employee training.
