Brayton Purcell LLP Releases New Podcast Episode

Brayton Purcell LLP has recently unveiled Episode 11 of its podcast series, From Dust to Verdict, which provides a comprehensive analysis of two major governmental hearings concerning the urgent public health crisis linked to artificial stone countertop manufacturing. The episode addresses the testimony that was shared at the Cal/OSHA Standards Board meeting and the U.S. House Subcommittee session discussing HR 5437, the bill proposing to shield foreign manufacturers of crystalline silica artificial stone from legal accountability.

In-Depth Discussion on Silicosis Crisis

During the January 15, 2026, Cal/OSHA Standards Board meeting, the pressing issue of silicosis among workers exposed to crystalline silica artificial stone was spotlighted. Although the Western Occupational and Environmental Medical Association (WOEMA)—a coalition of over 600 occupational medicine physicians—submitted a petition regarding these concerns, they were not granted an extensive opportunity to present. In stark contrast, the board allowed a prolonged counter-presentation from the ISFA, a trade association representing foreign slab manufacturers, distributors, and equipment suppliers.

James Nevin, the host of the podcast and a partner at Brayton Purcell LLP, shared his brief, two-minute testimony, emphasizing that his firm represents around 500 California fabrication workers who advocate for WOEMA's petition. He highlighted the significantly toxic nature of nano-sized particles found in crystalline silica artificial stone, which is often combined with additional harmful metals and resins. These combinations pose severe health risks that cannot be effectively controlled, even in the most advanced fabrication environments.

Cal/OSHA medical experts substantiated Nevin's claims, revealing that more than half of California fabrication facilities have recorded silicosis cases. Testimonies from Dr. Robert Blink, an occupational medicine physician, and Cal/OSHA scientific staff confirmed that artificial stone poses greater risks than natural stone due to its smaller particle size, unique chemical structure, and heightened toxicity. Dr. Blink's testimony also noted that working with artificial stone safely would necessitate using
