3. Occupational Exposure Limits (OELs) In the United States, permissible exposure limit is 50 μg/m 3 (action limit 30 μg/m 3) (U.S. OSHA, ). There is a requirement for monitoring of B-Pb, medical surveillance, and reduction of exposure when the workers B-Pbs are > μg/L; at > μg/L, the worker should be removed from exposure.

4. Jan 26,  · Permissible exposure limit (PEL) is a regulatory limit on the amount or concentration of a substance in the air. This is usually based on an eight-hour time weighted average (TWA), although some are based on short-term exposure limits (STEL). Workplace environmental exposure limit (WEEL) may be expressed as TWA. Different time periods are.

5. Exposure limits are expressed according to the length of exposure: Time-Weighted Average (TWA) exposure limit: This exposure limit is based upon the number of hours in a work shift (i.e., 8-hour TWA, hour TWA). Therefore, the average exposure over the length of the work shift may not exceed the TWA exposure limit established for the hazardFile Size: 77KB.

8. Exposure assessments for epidemiologic studies often require the use of retrospective techniques to make use of historical measurement data to create a job-exposure matrix. To be most successful, this technique relies on the past collection and retention of comprehensive, relevant exposure data.
