Guidance for using this Data in DOEHRS is as follows: Vibration magnitudes of the same equipment and vibration exposure times can be used to estimate a Daily Exposure Value for Similar Exposure Groups to support your Ergonomic Exposure Assessment and justify your Evaluation Rationale. If Daily Exposure Values are similar to the DEAV or DELV, it is highly recommended that a more stringent assessment of your workers' exposures be completed.
