The Mine Safety and Health Administration (MSHA) received a petition from Blue Diamond Coal Co. to modify existing safety standards that require the use of permissible electric equipment in coal mines. The company requested permission to use specific types of Powered Air Purifying Respirators (PAPRs), which are not MSHA-approved, as alternatives to currently used respirators. They argue these devices can offer air filtration and comfort, especially for miners with facial hair who might otherwise struggle with current equipment. The proposal includes specific guidelines and conditions to ensure the safety of miners when using these PAPRs underground.
