Background – Public Health and the Need for Employer Accountability
Senate Bill 20, also called the Silicosis Training, Outreach, and Prevention (STOP) Act, was signed into law by Governor Newsom on October 13, 2025.1 Senator Caroline Menjivar is on the forefront of this battle to avoid preventable injuries and illnesses by enforcing proper safety measures at fabrication shops.
In July, a proposed bill named the Silicosis Prevention Act was withdrawn from consideration in California. This proposed bill would have substantially affected the manufactured stone industry by banning dry fabrication activities, imposing licensing requirements for employers and workers, and implementing a public database for violations and other state enforcement actions. Even though this version of the proposed bill was withdrawn, further legislative efforts targeting the manufactured stone industry are anticipated in the future.
