California is moving to ban quartz countertop production, becoming the first state to block the industry. The measure targets a material linked to a deadly lung disease in workers.
Lawmakers cited silicosis, an incurable condition caused by inhaling silica dust. Quartz countertops contain high levels of crystalline silica.
Fabrication workers face the greatest risk as they cut and polish slabs. The dust can scar lungs and lead to respiratory failure.
State officials say current safety rules have failed to protect employees. Reports show rising cases among young workers in fabrication shops.
The ban would phase out manufacturing and import of the material. Installers and retailers would also face new restrictions.
Industry groups warn of economic fallout and job losses. They argue that proper ventilation and protective gear can reduce risks.
Public health advocates call the move a necessary step. They say voluntary compliance has not stopped preventable illnesses.
If enacted, the law could set a precedent for other states. Several are reportedly considering similar action.
