Cal/OSHA Engineered Stone Advisory Meeting
Your Voice Can Help Shape California's New Rule
Make Your Voice Count
On July 31, 2026, Cal/OSHA will hold an advisory meeting to help shape emergency regulations governing engineered stone containing more than 1% crystalline silica. While emergency rulemaking has already been directed, several important implementation details remain under consideration—including transition timelines, protection for existing contracts, engineering controls, and certification of alternative materials.
Why This Matters
The decisions made during this process will directly affect fabrication businesses throughout California. Regulators are asking for operational feedback from shops on transition periods, existing contracts, engineering controls, and practical implementation timelines.
