What is the permissible exposure limit (PEL) for asbestos over an 8-hour shift?

The permissible exposure limit (PEL) for asbestos over an 8-hour shift is set at 0.1 fibers per cubic centimeter (f/cc) of air. This standard is established to protect workers from the harmful health effects associated with asbestos exposure, which can lead to serious diseases, including asbestosis, lung cancer, and mesothelioma.

This limit is based on extensive research and findings that demonstrate the unacceptably high risk of developing asbestos-related illnesses at higher fiber concentrations. By setting a PEL of 0.1 f/cc, regulatory agencies aim to mitigate these risks, ensuring that the workplace remains as safe as possible for employees potentially exposed to asbestos.

While other options present different fiber concentrations, none align with the established standard for permissible exposure. This emphasizes the importance of adherence to regulatory guidelines in safeguarding health within occupational settings where asbestos may be present.
