Sec. 62.140  Dual hearing protection level.

    If during any work shift a miner's noise exposure exceeds the dual 
hearing protection level, the mine operator must, in addition to the 
actions required for noise exposures that exceed the permissible 
exposure level, provide and ensure the concurrent use of both an ear 
plug and an ear muff type hearing protector. The following table sets 
out mine operator actions under MSHA's noise standard.
