Silicosis is an occupational lung disease, which may affect workers in the stone fabrication industry if they process marble, granite, quartz surfaces and other natural stones without safety measures. The disease forms when silica dust particles become trapped in lung tissues, causing inflammation and scarring, and reducing the lung’s ability to take in oxygen.
