Episode 14: Cal/OSHA Hears from the Workers

Episode 14 of From Dust to Verdict, “Cal/OSHA Hears from the Workers,” documents the pivotal April 16, 2026 hearing before the Cal/OSHA Standards Board, held just weeks before the Board’s scheduled May 21 vote on the WOEMA petition. Hosted by James Nevin of Brayton Purcell LLP, the episode captures a rare and consequential moment in the public record: for one of the final standards hearings, the Standards Board invited countertop fabrication workers themselves to testify, rather than hearing primarily from artificial stone slab manufacturers and industry lobbyists. The episode centers on firsthand accounts from fabrication workers across California who describe years spent cutting, shaping, and finishing crystalline silica artificial stone slabs. Workers from Orange, Solano, Los Angeles, and Alameda Counties explain that even while using wet cutting methods, masks, and ventilation, dust remained ever‑present in the shops. Several testified that they were diagnosed with artificial stone silicosis between 2022 and 2024, in the prime of their lives, and that they were never warned by manufacturers or suppliers about the dangers associated with artificial stone. Listeners hear deeply personal testimony describing the physical, emotional, and financial consequences of the disease. Workers spoke about losing their ability to work, provide for their families, and participate in everyday life. One worker describes undergoing a lung transplant because of his work in the countertop fabrication industry. Others explain that they only learned what silicosis was after becoming seriously ill, emphasizing that had they known the risks earlier, their lives could have taken a very different path. Medical and public health professionals also testify that artificial stone causes a distinct and aggressive form of silicosis unlike historical cases associated with natural stone. Physicians, nurses, and occupational health specialists describe rapid disease progression, short latency periods, and severe outcomes, including respiratory failure and premature death. They explain that artificial stone is at least 90% silica, that the silica particles are nano‑sized, and that the remaining approximate 10% consists of other toxins and carcinogens known as volatile organic compounds. Together, these characteristics create exposure conditions that cannot be effectively controlled in real‑world fabrication settings. A California fabricator explains that his shop transitioned to recycled glass, zero‑silica slabs and subsequently recorded air‑sampling results below detectable limits, demonstrating that safer materials are already being used in practice. Manufacturers and trade association representatives opposed prohibition and urged reliance on enforcement, training, and certification programs. Episode 14 places those positions in context by contrasting them with testimony reflecting peer‑reviewed scientific literature discussed throughout the podcast series. That body of research reports persistent hazardous exposure and disease patterns among artificial stone fabrication workers and concludes that fabrication of crystalline silica artificial stone cannot be performed safely by human beings, even with advanced engineering controls and personal protective equipment. The episode concludes with remarks from Charley Velasco of Brayton Purcell LLP, who spoke directly to the Standards Board at the hearing. Charley described the human toll he witnesses every day in his work with hundreds of workers living with artificial stone silicosis—many of whom are now permanently disabled, awaiting lung transplants, or have already lost their lives. Together, James Nevin and Charley Velasco frame the hearing not as an abstract policy debate, but as a record of preventable human suffering and the voices of workers whose lives have been irrevocably changed.
