  • Description:
    Overexposure to airborne respirable crystalline silica (or quartz) dust can cause serious or fatal respiratory disease. In particular, some of the most severe cases of silicosis have been observed in surface mine rock drillers. A voluntary lung screening study conducted on surface coal mine workers in Pennsylvania concluded that the incidence rate of silicosis is directly related to age and years of drilling experience. Dust sampling data from the Mine Safety and Health Administration show that the drilling machine operator continues to frequently exceed the federally mandated quartz dust standard.
