Silicosis, a disease caused by silica dust produced when workers cut and grind engineered stone, is afflicting workers. What consumers can do about it.
During various mining processes in which rock/minerals are broken up and collected for processing, mineral dusts are created and become airborne. Inhalation of these dusts can lead to various respiratory illnesses, depending on the dust type (e.g. coal, silica, etc.), size of the dust particulates, and exposure duration. [4]
Researchers estimated that 100,000 workers in the U.S. are potentially at risk of silicosis due to exposure to silica dust. ... It is time for urgent action to stop these dangerous working ...
