Mine Safety and Health Administration June 9, 2009 – Federal Register Recent Federal Regulation Documents

The Mine Safety and Health Administration (MSHA) and the National Institute for Occupational Safety and Health (NIOSH) will hold a public hearing on the proposed rule to revise existing requirements to approve sampling devices that monitor miner exposure to respirable coal mine dust. The proposal would establish criteria for the approval of a new type of technology, the ``continuous personal dust monitor'' (CPDM), which would be worn by the miner and would report exposure to dust levels continuously during the shift. In addition, the proposal would update application requirements for the existing ``coal mine dust personal sampler unit'' (CMDPSU) to reflect improvements in this sampler over the past 15 years. This rulemaking is limited to approval
