WHAT ARE THE OCCUPATIONAL EXPOSURE LIMITS FOR WORKPLACE NOISE?
Occupational exposure limits (OELs) for noise are typically given as the maximum duration of exposure permitted for various noise levels. They are often displayed in exposure-duration tables like Table 1A and Table 1B. The OELs depend on two key factors that are used to prepare exposure-duration tables: the criterion level and the exchange rate.| Table 1A Noise Exposure Limits when Criterion Level = 85 dBA | ||
|---|---|---|
| 3 dBA Exchange Rate | Maximum Permitted Daily Duration (hours) | 5 dBA Exchange Rate |
| Allowable Level dBA | Allowable Level dBA | |
| 85 | 8 | 85 |
