Arlington, VA — The Mine Safety and Health Administration is reminding miners to keep at least 6 inches of separation between their powered air-purifying respirator and proximity detection system.
In a recently published safety alert, MSHA offers illustrations showing proper positioning of a miner-worn PDS when using PAPRs supported by a belt or as a neck support.
The agency notes that “electromagnetic interference can cause failure of a miner-worn PDS if it is not worn as recommended, such as being worn too close to the battery or motor/blower of a PAPR.”

MSHA adds that, since last year, 33 mines have been allowed to use a PAPR through the Petition for Modification process.
