The HHE Program responded to a request at a pottery shop which concerned potential exposures to silica, volatile organic compounds, and dry materials mixed there. HHE Program investigators collected personal breathing zone, area air, and surface wipe samples, measured carbon monoxide (CO) during forklift use, and performed an ergonomic assessment of work practices. Investigators found that one employee's exposure for silica was at the NIOSH recommended exposure limit of 0.05 mg/m3. They also found that some samples taken during high dust-generating tasks exceeded the excursion limit for silica. CO levels measured in the facility exceeded the NIOSH ceiling limit of 200 parts per million during forklift use. Investigators also noticed that some workers were not wearing their respirators properly. HHE Program investigators recommended that facility managers install local exhaust ventilation in high dust-generating task areas and improve the central building ventilation to increase overall air mixing. Investigators also recommended that managers ensure that employees wear respirators and that employees use respirators when needed. HHE Program investigators also recommended that employees properly store and maintain all personal protective equipment.
