In response to a request from the West Virginia University, Office of Environmental Health and Safety, an investigation was made of possible hazardous working conditions at the University Pottery Shop (SIC-3269), Morgantown, West Virginia. The Shop provided classes for university students. The purpose for the evaluation was to consider silica (14808607) exposure during clay mixing operations. There was no local exhaust ventilation provided for the control of dusts generated during either the weighing or mixing of the dry ingredients. Only one of the collected samples showed quantifiable levels of quartz. The sample concentration of respirable quartz was 169.5 micrograms per cubic meter of air. Exposure to respirable dust, however, was considerable for short durations. The author concludes that a potential health hazard existed at the Pottery Shop. The author recommends that, due to the crystalline silica content of the clay and related products used in the pottery shop, and the potential for high dust exposure, a dust control system should be installed in the mixing room.
