dust exposure of stone grinding mill workers

  • Severe Silicosis in Engineered Stone Fabrication Workers

    Sep 26, 2019· Because quartz, a type of crystalline silica, is commonly found in stone, workers who cut, polish, or grind stone materials can be exposed to silica dust.

  • Is exposure to airborne concrete, stone, brick, or granite

    Dec 08, 2015· When materials such as concrete, stone, brick, or granite are cut or ground by workers, it can create extremely fine dust particles, which can make their way deep into the lungs if inhaled. These silica dust particles can cause scarring in the lungs, leading to a serious and irreversible lung condition known as silicosis.
