A petition for modification was submitted to the Mine Safety and Health Administration (MSHA) by Wolf Run Mining, LLC, requesting a change in the safety standard for respirable dust protection at the Leer South Mine in West Virginia. The mining company wishes to use alternative protective gear, specifically the 3M Versaflo TR-800 and the CleanSpace EX Powered Air Purifying Respirators (PAPRs), which are not currently MSHA-approved. The petition argues that these respirators provide an equivalent or better level of protection compared to the existing standards. The proposal outlines specific safety measures and training programs to ensure the safe use of these devices. Public comments on this petition are open until May 19, 2025.
Simple Explanation
People are asking if a mine can use special masks to protect workers from dust because they believe these masks, which aren't usually allowed, work just as well. They want to hear what everyone thinks about this idea until May 19, 2025.
