Washington, DC – OSHA recently issued a compliance directive designed to ensure uniformity in inspection and enforcement procedures when addressing respirable crystalline silica exposures in general industry, maritime, and construction. The new directive provides OSHA compliance safety and health officers with guidance on how to enforce the silica standards’ requirements. The directive also provides clarity on major topics, such as alternative exposure control methods when a construction employer does not fully and properly implement Table 1, variability in sampling, multi-employer situations, and temporary workers.
