OSHA's 2026 Focus on Engineered-Stone Silica Raises the Surveillance Bar
OSHA's 2026 enforcement emphasis under the crystalline-silica standards (1910.1053 and 1926.1153) centers on high-exposure trigger tasks, with particular attention to engineered stone containing more than 0.1% crystalline silica. Fabrication and finishing of those materials produce some of the highest airborne concentrations in the workplace, and the agency has made clear it is watching them.
For employers, the compliance backbone is medical surveillance: an exam offered at no cost, at a reasonable time and place, to every worker required to wear a respirator for 30 or more days a year, performed by a PLHCP and including spirometry and a B-reader chest X-ray. The baseline is due within 30 days of assignment unless a qualifying exam was done in the prior three years.
Meeting that duty across a distributed or shift-based workforce is where mobile screening earns its keep — the exam comes to the worksite, and the records come back audit-ready.
