What is the Permissible Exposure Limit (PEL) for asbestos according to OSHA standards?

The Permissible Exposure Limit (PEL) for asbestos set by OSHA is 0.1 fibers per cubic centimeter (f/cc) averaged over an 8-hour workday (TWA). This standard was established to protect workers from the harmful effects of asbestos exposure, which is associated with serious health risks including asbestosis, lung cancer, and mesothelioma.

A PEL of 0.1 f/cc means that, over the course of an 8-hour shift, the average concentration of airborne asbestos fibers should not exceed this amount. This limit is part of OSHA's broader regulation aimed at minimizing exposure and protecting workers in environments where asbestos may be present.

The other options present higher thresholds, which do not align with OSHA's established guidelines for safe exposure levels. Maintaining exposure below 0.1 f/cc is critical for safeguarding the health of workers who may be involved in activities where asbestos is present.
