The Mine Safety and Health Administration (MSHA) received a petition from Kanawha Eagle Mining, LLC, requesting a change to current safety standards. The petition seeks to use the CleanSpace EX and 3M Versaflo TR-800 Powered Air Purifying Respirators (PAPRs) that are not currently MSHA-approved, but provide an alternative method of protection for miners. These PAPRs offer constant airflow and are said to be more comfortable, particularly for miners who have facial hair or cannot wear tight-fitting respirators. The proposed modification includes specific conditions for training, maintenance, and use to ensure safety is not compromised.
Simple Explanation
Kanawha Eagle Mining, LLC asked for a change in safety rules to use special breathing masks that are comfy and work well but are not yet officially approved. They're making sure these masks are used safely and teaching miners how to use them.
