Law firm Brayton Purcell LLP draws attention to a medical report linking artificial‑stone silicosis to rapid disease progression and inadequate conventional dust controls
Executive summary: Brayton Purcell LLP issued a press release highlighting a recent American Thoracic Society workshop report that warns of rapidly progressive silicosis among workers exposed to artificial stone and notes that conventional ventilation and wet methods are insufficient to control exposure. The findings raise potential liability for manufacturers of quartz countertops and other engineered stone products, and may trigger tighter occupational‑health regulations and increased workers‑compensation claims.
Who is involved: Brayton Purcell LLP (law firm), the American Thoracic Society, workers in the artificial‑stone fabrication industry, and manufacturers such as Caesarstone, Cosentino, and LG Hausys.
Likely next: Regulatory agencies may review silica exposure limits, and affected workers or their representatives could pursue legal action; industry groups may accelerate adoption of engineering controls or substitute materials.
Brayton Purcell LLP released a press statement highlighting a recent American Thoracic Society workshop report that warns of rapidly progressive silicosis among workers exposed to artificial stone and notes that conventional ventilation and wet methods are insufficient to control exposure. The findings raise potential liability for manufacturers of quartz countertops and other engineered stone products, and may trigger tighter occupational‑health regulations and increased workers‑compensation claims. While the report does not quantify the number of affected workers, it underscores a growing occupational‑health concern that could prompt regulatory review and legal action.

Sectors affected
- Artificial stone (quartz) countertop manufacturing
- Stone fabrication and installation contractors
- Occupational health and safety consulting services
Regulatory implications
- OSHA may reduce the respirable crystalline silica PEL from 50 µg/m³ to 25 µg/m³ under 29 CFR 1910.1053.
- Cal/OSHA may issue an emergency temporary standard requiring engineering controls and medical surveillance for artificial‑stone workers by Q4 2026.
- The European Chemicals Agency (ECHA) could evaluate adding engineered stone to the REACH list of substances of very high concern (SVHC) in 2027.
Historical parallels
