Cleveland Akron, OH, October 7, 2026 —
California is moving towards prohibiting certain types of engineered quartz countertops due to mounting concerns over a serious and potentially fatal lung disease linked to occupational exposure to silica dust.
The state’s Occupational Safety and Health Standards Board is reportedly preparing to vote on an emergency rule aimed at regulating manufactured stone products. This proposed rule would specifically target products that contain more than 1% crystalline silica.
The substance in question, crystalline silica, is a common mineral found in many building materials. When these materials are cut, ground, or polished, microscopic particles of silica dust can become airborne. Workers in the countertop fabrication industry, particularly those handling engineered stone, are at risk of inhaling this dust.
Prolonged exposure to airborne silica dust can lead to silicosis, a progressive and irreversible lung disease. This condition can cause severe respiratory problems, disability, and has been associated with increased mortality among affected workers. The trend summary indicates that these health concerns are the primary driver behind the proposed regulatory action.
The emergency rule is anticipated to be put to a vote in October. If approved, it would signify a significant regulatory shift concerning the materials used and sold within the state for residential and commercial installations. The specific details of the ban, including its exact scope and implementation timeline, will be clarified following the board’s decision.
Details regarding the specific types of engineered stone that will be affected by the ban, beyond the 1% crystalline silica threshold, were not immediately available in the summary. The outcome of the October vote will determine the next steps in addressing worker safety in the countertop industry in California.
