Oct 29, 2019 Exposure to silica dust is a health hazard for workers who manufacture, finish, and install natural and engineered stone countertop products. Symptoms of silicosis may include cough, fatigue, shortness of breath, or chest pain. Silicosis typically occurs after 10 or more years of exposure to respirable crystalline silica.get price

The particles are "inorganic" or "organic," depending on the source of the dust. Inorganic dusts can come from grinding metals or minerals such as rock or soil. Examples of inorganic dusts are silica, asbestos, and coal. Organic dusts originate from plants or animals. An example of organic dust is dust that arises from handling grain.get price
