The Mine Safety and Health Administration (MSHA) received a petition from Rockwell Mining, LLC, seeking permission to use certain unapproved powered air purifying respirators (PAPRs) in their mine. These respirators, including the CleanSpace EX and 3M Versaflo TR-800, offer benefits like airflow comfort and suitability for miners with facial hair. Rockwell Mining argues these devices provide equal or better protection than currently approved options. The request also includes conditions like equipment inspection, miner training, and specific battery safety measures. Comments on the petition are open until January 9, 2025.
Simple Explanation
Rockwell Mining wants to use special masks in their mine that are not officially approved yet, saying they help miners breathe better, especially if they have beards. They promise to keep the equipment safe and teach the miners how to use them, and people can say what they think about this idea until January 9, 2025.
