The potential for respirable silica dust exposure to workers in the stone and metal/nonmetal mining industry is related to the percentage of silica in the product being mined or processed. For crushed and broken stone or …
The potential for respirable silica dust exposure to workers in the stone and metal/nonmetal mining industry is related to the percentage of silica in the product being mined or processed. For crushed and broken stone or dimension stone, silica percentages are on the high end, with sandstones and granites averaging 70% to 90%.

Silica exposure also increases the risk of bacterial infections, such as tuberculosis. "Depending on the disease and symptoms ranging anywhere from shortness of breath to the need to be on supplemental oxygen full-time. The course of treatment, which normally includes inhalers and steroids, is up to the pulmonologist but many times …
Aliabadi et al. investigated the effect of LEV on workers' exposure to silica dust in the crushing plants in Hamedan Province. Their findings indicate the …
Cumulative exposure was the best predictor of disease, followed by duration of exposure and average exposure. After adjustment for competing risks of death, a 45-year exposure under the current OSHA standard would lead to a lifetime risk of silicosis of 35% to 47%. CONCLUSIONS. Almost 2 million US workers are currently exposed to silica.

It can also cause lung cancer. Cutting, breaking, crushing, drilling, grinding, or blasting concrete or stone releases the dust. As workers breathe in the dust the silica settles in their lungs. For information on protecting workers from harmful exposure to silica dust, see the resources section below, which includes a silica control tool.
Silica Dust Exposure Recognize the hazard. Milling, cutting, or otherwise disturbing asphalt pavement can create airborne dust containing silica. Pay attention to wind direction and any visible dust emissions. Use ventilation and water-spray controls on asphalt pavement milling machines.
