Since 2017, 2 fatalities in 18 cases of silicosis across 4 states has brought new focus to the respiratory health of more than 96,000 employees employed by nearly 8,700 stone fabrication industry businesses across the United States.
- Silicosis is a progressive, potentially fatal lung disease caused by occupational exposure to respirable c-silica. Adverse health effects from inhalation exposure includes the resipratory, renal, and immune systems
- Engineered stone typically contains over 90% silica, as compared to less than 45% in granite and less than 10% in marble
- The first reported case of silicosis in North America was in 2014 from an employee of a countertop company
- In 2015 OSHA issued a "hazard alert" warning of exposure risk for workers who manufacture natural and artificial stone countertops
- There is scant data on the prevalence of silicosis and its associated conditions in stone fabrication workers in the United States, as screening standards have only recently been put in place and varies by jurisdiction
- A comprehensive screening in Queensland, Australia found 12% (98 cases) of 799 stone fabrication workers had silicosis
- Silicosis is preventable through effective workplace exposure controls, such as water feeds, ample ventilation, and appropriate respiratory protection
- The US Agency for Toxic Substances and Disease Registry (ATSDR) did not identify minimum risk levels (MRLs) for inhaled c-silica for any exposure duration in their toxicological profile, given the "serious nature of silicosis and the uncertainties associated with identification of a no-effect level"
- The current federal and state OSHA standard for respirable crystalline silica permissible exposure limit (PEL) is 0.05 mg/m3, as it has been since 2016
