Exposure to respirable silica-bearing dust (silica dust) can put miners at grave risk. Silicosis, a potentially fatal lung disease associated with overexposure to silica dust, is entirely preventable if mine operators and miners act in concert to prevent exposures to hazardous levels of silica dust. Under the Coal Act, the Mine Safety and Health Administration (MSHA) required a reduced dust limit if the silica content in a dust sample exceeds 5%, effectively establishing a respirable silica PEL of 100 μg/m 3. MSHA conducts periodic inspections at coal
