What is the permissible exposure limit (PEL) for asbestos set by OSHA?

The permissible exposure limit (PEL) for asbestos established by OSHA is indeed set at 0.1 fibers per cubic centimeter (f/cc) of air, measured as an 8-hour time-weighted average (TWA). This standard is crucial for protecting workers' health, as asbestos exposure is linked to serious illnesses, including asbestosis, lung cancer, and mesothelioma. The 8-hour TWA accounts for the average exposure a worker can have over a standard workday, offering a benchmark to ensure safety in occupational environments where asbestos may be present.

Other options present limits that are either higher or incorrectly defined. A limit of 0.5 f/cc exceeds the safe threshold recommended by OSHA. A PEL of 1 f/cc also fails to adhere to the more stringent safety standards necessary to minimize health risks associated with asbestos exposure, while 0.75 f/cc similarly does not meet the established measures. By understanding the correct PEL, individuals can better advocate for safety measures and compliance within their workplaces.
