  • 2025-07143 — Petition for Modification of Application of Existing Mandatory Safety Standards
    Type:Notice
    Citation:90 FR 17458
    Reading Time:about 7 minutes

    The Mine Safety and Health Administration (MSHA) received a petition from Century Mining, LLC to modify existing safety standards for using alternative respirable dust protection equipment. The petitioner seeks to use battery-powered respirators like the PureFlo ESM+ PF60, 3M Versaflo TR-300N, and Drager X-plore 8700 rather than the outdated 3M Airstream helmet, which is no longer available due to component disruptions. They assert that this alternative method will offer the same level of protection for miners while complying with safety standards. The proposed change includes specific guidelines for training, inspection, and usage to ensure miner safety, even though these new products do not currently meet MSHA approval.

    Simple Explanation

    Century Mining wants to use new, modern masks to keep miners safe because the old ones are not available anymore, but the new masks still need to get a special safety approval.

    The Mine Safety and Health Administration (MSHA) received a petition from ACI Tygart Valley requesting permission to use alternative respirable dust protection equipment at the Leer Mine, due to the discontinuation of previously used equipment. They propose to use the 3M Versaflo TR-800 and CleanSpace EX Powered Air Purifying Respirators (PAPRs) as replacements, despite these not being MSHA-approved. ACI Tygart Valley argues that the proposed equipment provides equivalent safety measures and includes training and inspection protocols to ensure miner safety. MSHA will consider public comments on this proposed modification until April 21, 2025.

    Simple Explanation

    The safety people for mines have been asked if a coal mine can use different masks because their old ones aren't made anymore. The mine says the new masks are just as safe, but they need permission to use them.
