"California regulators are weighing whether to effectively ban the fabrication of artificial stone amid mounting evidence that even rigorous safety measures may not protect workers from silicosis, an aggressive and often fatal lung disease."
"Artificial stone can contain more than 90% silica, which researchers deem uniquely toxic. Keeping exposures low enough at all times is extremely difficult, according to Harrington."
"Implementing the current Cal/OSHA rules, which require the wet cutting of artificial stone to limit dust exposure and other steps, significantly reduces airborne silica particles, according to Harrington."
California regulators are considering a ban on artificial stone fabrication due to increasing silicosis cases linked to the material. Fabricators have invested heavily in compliance with strict silica rules, but evidence suggests that even rigorous safety measures may not adequately protect workers. Artificial stone contains over 90% silica, which is highly toxic. Current safety measures, including wet cutting, reduce airborne silica but may still leave workers at risk of overexposure. The regulatory decision could significantly impact the industry and worker safety.
