Abstract
In response to a request from employees of Langers Black Hills Silver Jewelry (SIC-3911), an investigation was undertaken of possible hazardous working conditions at that site in Spearfish, South Dakota. Twenty one to 23 workers at the facility were engaged in making jewelry; processes used included lost wax casting, resin molding, and soldering. Personal air sampling was conducted to evaluate employee exposure to carbon-monoxide (630080), crystalline silica (14808607) and metal fume in the Casting Department, styrene (100425) in the Gems by Jim Department, and toluene (108883) and xylene (1330207) in the Box Filler Department. The ventilation systems used for contaminant control were evaluated, informal interviews with employees were conducted, and chemical handling practices were observed. All exposures were below recommended levels for all tasks monitored. Although the levels of silver (7440224) were below the NIOSH recommended exposure limit of systems, installed to control worker exposure to contaminants, were based on inappropriate design criteria. The author concludes that the silver level is of concern. The author recommends that controls to reduce exposure to silver fume be implemented, that employee training and respiratory protection programs be implemented, and that the exhaust ventilation system be improved.
