When employers obtain audiograms
in mobile test vans, baseline audiograms must be completed within one year after an
employee's first exposure to workplace noise at or above an average of 85 dBA. Additionally, when mobile vans are used and employers are allowed to delay baseline testing for up to a year, those employees exposed to levels of 85 dBA or more must be issued and fitted with hearing protectors six months after initial exposure. The hearing protectors are to be worn until the baseline audiogram is obtained. Baseline audiograms taken before the effective date of the amendment are acceptable as baselines in the program if the professional supervisor determines that the audiogram is valid. |
