MSHA Eases Rules for Miners' High-Tech Breathing Masks in Underground Peril
Published Date: 7/1/2025
Proposed Rule
Summary
MSHA wants to let underground mine workers use special air-purifying masks called PAPRs without extra paperwork, as long as the masks meet safety rules. This change helps miners breathe easier in gassy mines and saves mine bosses time and hassle. The new rule means faster approval and safer gear, with no extra costs expected.
Analyzed Economic Effects
3 provisions identified: 3 benefits, 0 costs, 0 mixed.
Allow PAPRs in gassy underground mines
The rule would let underground mine workers use non-permissible Powered Air Purifying Respirators (PAPRs) in specified underground gassy areas if the equipment meets certain technical specifications and is operated under specific conditions. MSHA says this helps miners breathe easier in gassy mines and enables safer gear to be used more quickly.
Technical and operating rules codified
The proposal would codify the technical specifications and working conditions under which non-permissible PAPRs may be used underground. Those codified specs and conditions would be required for the equipment to be allowed in the specified underground gassy areas.
Operators no longer need petitions
Mine operators would no longer need to submit a petition for modification to use non-permissible PAPRs in the covered underground areas. MSHA says this reduces administrative burden and saves time and hassle for mine operators, with no extra costs expected.
