  • 2024-30944 — Petition for Modification of Application of Existing Mandatory Safety Standards
    Type:Notice
    Citation:89 FR 105629
    Reading Time:about 11 minutes

    Wolf Run Mining, LLC submitted a petition to the Mine Safety and Health Administration (MSHA) requesting a change to the safety standards for their Leer South Mine. They want to use new types of air purifying respirators, the 3M Versaflo TR-800 and CleanSpace EX, instead of the discontinued 3M Airstream. These respirators are not MSHA-approved, but the company believes they provide equal or better protection and are safe to use. The proposal involves specific training, inspection, and maintenance procedures to ensure safety, especially in areas where methane gas might be present.

    Simple Explanation

    Wolf Run Mining wants to use new breathing masks in their mine because the old ones are not made anymore. They promise these new masks work just as well and keep the miners safe.

    ICG Beckley, LLC has asked the Mine Safety and Health Administration (MSHA) to allow the use of certain air purifying respirators to protect miners at its Beckley Pocahontas Mine in West Virginia. These respirators, specifically the CleanSpace EX and 3M Versaflo TR-800, are not currently approved under MSHA standards, but the company argues they offer comparable protection and comfort, especially in hot working conditions. The petition highlights issues with the supply and discontinuation of previously used equipment and outlines rigorous inspection and training procedures to ensure safety. MSHA is accepting public comments on the petition until April 21, 2025.

    Simple Explanation

    ICG Beckley, which runs a mine, is asking for permission to use special masks to keep workers safe, even though these masks aren't officially approved yet. They believe the new masks work well and are asking people to share their thoughts about this idea by April 21, 2025.
