Mine Safety and Health Administration July 29, 2005 – Federal Register Recent Federal Regulation Documents

We (MSHA) are proposing to revise our existing health standards for asbestos exposure at metal and nonmetal mines, surface coal mines, and surface areas of underground coal mines. The proposed rule would reduce the full-shift permissible exposure limit and the excursion limit for airborne asbestos fibers, and make several nonsubstantive changes to add clarity to the standard. Exposure to asbestos has been associated with lung and other cancers, mesotheliomas, and asbestosis. This proposed rule would help assure that fewer miners who work in an environment where asbestos is present would suffer material impairment of health or functional capacity over their working lifetime.
