National Occupational Health Survey of Mining. Marble (Crushed and Broken) Report

摘要

The report provided data concerning potential occupational exposures of workers involved in the mining of marble, crushed and broken. Three sample sites were selected from the marble mining population of active facilities. The report identified potential exposures and provided the associated numbers of workers, the occupations of those workers, and the locations on the mining property where the potential exposures were observed. The products and conditions to which workers were potentially exposed included: three Mine Safety and Health Administration (MSHA) regulated chemicals; two chemicals with a NIOSH Recommended Exposure Limit but not regulated by MSHA; three chemicals without NIOSH or MSHA limits; 87 trade name products; four physical agent conditions; 12 musculoskeletal overload conditions; and two welding processes. Estimated annual usage information was provided for chemical substances, both generic and trade name.
