California board expected to propose ban on engineered quartz countertops amid silicosis outbreak

Health

The California Occupational Safety and Health Standards Board said it is set to propose an emergency rule that would bar the manufacture and installation of engineered quartz countertops containing more than 1 % crystalline silica, as a silicosis outbreak among workers is reported. The proposal follows earlier indications that the board was preparing an emergency regulation after a sharp increase in silicosis cases among stone-working employees was documented. Earlier reports said the state would become the first to ban such quartz production, and the board was slated to vote on the rule.
