Rockwell Mining, LLC has submitted a petition to the Mine Safety and Health Administration (MSHA) to modify an existing safety standard for their Coal Branch No. 1 Mine in West Virginia. The company wants permission to use specific Powered Air Purifying Respirators (PAPRs) underground, which are not MSHA-approved but considered intrinsically safe by the company. These respirators, made by 3M and CleanSpace, offer constant airflow and protection, especially benefiting miners with facial hair or those who struggle with tight-fitting masks. The petition outlines detailed training, examination, and maintenance requirements to ensure the equipment is used safely.

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.

Rockwell Mining, LLC has requested a modification to allow the use of certain Powered Air Purifying Respirators (PAPRs) within 150 feet of pillar workings or longwall faces at their Gateway Eagle Mine in West Virginia. The Mine Safety and Health Administration (MSHA) is considering this petition, which suggests using two specific models of PAPRs—CleanSpace EX and 3M Versaflo TR-800—that are not currently MSHA-approved but deemed intrinsically safe by the manufacturer. Rockwell argues that these devices provide high levels of respiratory protection and comfort, especially for miners with facial hair who struggle with traditional respirators. They propose comprehensive training and maintenance protocols to ensure miner safety.

The Mine Safety and Health Administration (MSHA) received a petition from Blue Diamond Coal Co. seeking to modify existing safety standards to allow specific types of powered air purifying respirators (PAPRs) in certain mining areas. The company requested permission to use the CleanSpace EX and 3M Versaflo TR-800 PAPRs, which are not MSHA-approved but are claimed to be intrinsically safe. These respirators offer continuous airflow and may better protect miners, including those with facial hair, from harmful dust than the current equipment. The proposal includes specific training and safety checks to ensure the devices' safe use.

The Mine Safety and Health Administration (MSHA) has received a petition from ICG Beckley, LLC for a modification to existing mine safety standards. The company wants to use unapproved Powered Air Purifying Respirators (PAPRs), specifically the CleanSpace EX and 3M Versaflo TR-800, in certain mining environments. These devices are suggested as alternatives to the discontinued 3M Airstream helmet, providing respiratory protection from coal mine dust. ICG Beckley argues that their use will maintain or enhance miner safety, even though these devices aren't MSHA approved. They propose extensive training, regular inspections, and strict conditions for using these PAPRs to ensure miner safety.
