Determining employee time-weighted average noise exposures for facilities with 8-hour work shifts is a fairly straightforward procedure. However, confusion often reigns when extended work shifts (e.g., 10-hour, 12-hour workdays) exist. To handle exposure data for workdays greater than 8 hours there are at least three viable options. The data may be normalized to an 8-hour day for direct comparison to the applicable regulation criteria, the average sound level may be compared to a sliding-scale criteria, or the full-shift projected dose may be utilized. This webinar shall demonstrate through example how to appropriately manage the data, plus describe the pros and cons of each method. No CEUs will be offered for this webinar.
