# §62.174. Follow-up corrective measures when a standard threshold shift is detected.


The mine operator must, within 30 calendar days of receiving evidence or confirmation of a standard threshold shift, unless a physician or audiologist determines the standard threshold shift is neither work-related nor aggravated by occupational noise exposure:

- (a) Retrain the miner, including the instruction required by [§ 62.180](/cfr/30/62.180.md) of this part;
- (b) Provide the miner with the opportunity to select a hearing protector, or a different hearing protector if the miner has previously selected a hearing protector, from among those offered by the mine operator in accordance with [§ 62.160](/cfr/30/62.160.md) of this part; and
- (c) Review the effectiveness of any engineering and administrative controls to identify and correct any deficiencies.
