Summary: | Researchers from the National Institute for Occupational Safety and Health (NIOSH) conducted a joint survey with the New Jersey Department of Health (NJDOH) to measure crystalline silica exposures and evaluate the adequacy of the existing control measures for reducing these exposures at a sanitary ware pottery. This survey found that 95% of the personal and area samples from the Slip House, Casting, Glaze Spray, and Glaze Preparation Departments exceeded the NIOSH Recommended Exposure Level (87% exceeded the Occupational Safety and Health Administration Permissible Exposure Level) for crystalline silica. Three years later, a follow-up survey found statistically significant reductions in respirable crystalline silica exposures in two of four plant departments, and statistically significant reductions in area concentrations in all four plant departments. These reductions were accomplished through a combination of automating and enclosing the batching system in the Slip House and by replacing the mold parting compound with a nonsilica material, altering the method of dry sweeping, cleaning of castings while damp, improving exhaust ventilation at the spray booths, and improved housekeeping. |
