The Mine Safety and Health Administration (MSHA), part of the Labor Department, received a petition from ACNR Holdings, Inc. to modify existing safety standards for certain mines in West Virginia. They propose using the 3M Versaflo TR-800 Powered Air Purifying Respirator (PAPR) as an alternative for respirable dust protection near mining areas. ACNR Holdings argues that their proposed alternative method will provide the same or better safety for miners. The public is invited to comment on this petition by May 19, 2025.
Simple Explanation
The Mine Safety and Health Administration is thinking about changing some rules to let a mining company use a special type of mask to keep workers safe from dust. People can say what they think about this idea until May 19, 2025.
