The Mine Safety and Health Administration (MSHA) received a petition from Rockwell Mining, LLC, to allow the use of certain powered air purifying respirators (PAPRs) in specific areas of a mine, such as near pillar workings or longwall faces. These PAPRs, which include the CleanSpace EX and the 3M Versaflo TR-800s, are not MSHA-approved, but the petitioner claims they are intrinsically safe and offer better protection and comfort in hot conditions. The company proposes a detailed alternative method for ensuring safety, including training, inspections, and compliance with specific maintenance requirements. The notice invites public comments on the petition until January 15, 2025.
Simple Explanation
Rockwell Mining wants to use special safety masks in their mines that haven't been officially approved yet, but they say these masks work well and are safe. The Mine Safety and Health Administration is asking people what they think about this idea until January 15, 2025.
