1219-AC17 202504 Unified Agenda of Federal Regulatory and Deregulatory Actions 1219 Mine Safety and Health Administration MSHA 1200 Department of Labor DOL Powered Air Purifying Respirators (PAPRs) in Underground Mines

The Mine Safety and Health Administration (MSHA)is proposing to allow the use of non-permissible Powered Air Purifying Respirators (PAPRs) in high-hazard areas of mines, if the equipment meets certain technical specifications and is operated under specific conditions. This proposed rule would codify technical specifications and working conditions to allow the use of non-permissible PAPRs in underground gassy mines. This proposed rule would reduce burden because mine operators would no longer need to submit a petition for modification to use non-permissible PAPRs.
