The largest number of silicosis cases in New Jersey exist in the sand mining and processing, foundry, and pottery (sanitary were) industries. Early in 1988, an informal working agreement was established between the New Jersey Department of Health and the NIOSH Division of Engineering and Physical Sciences, to conduct a comprehensive study in one facility in each of these industries. Studies were performed to develop specific control recommendations for each facility and to provide training in survey techniques and in the application of engineering controls for state personnel. These studies found that about 50% of the pottery workers, 33% of the foundry workers, and none of the sand mine workers were overexposed to silica. Other exposure hazards were also identified. Material handling operations were found to be a major source of potential silica exposure in all three plants. Recommendations for exposure reduction included: substitution of non-silica materials where possible, improvements in existing ventilation, and automation of material handling tasks. Follow-up visits indicated good compliance with the recommendations. These case reports demonstrate the value of active surveillance in silicosis prevention and the value of state/federal cooperation.
