What is the Permissible Exposure Level for asbestos over an 8-hour time-weighted average?

The Permissible Exposure Level (PEL) for asbestos is an important regulatory limit established to protect workers from the harmful effects of asbestos exposure. The correct answer of 0.1 f/cc signifies that this is the maximum allowable concentration of asbestos fibers in the air that a worker can be exposed to over an 8-hour time-weighted average.

This limit is crucial because occupational exposure to asbestos can lead to serious health issues such as asbestosis, lung cancer, and mesothelioma. The 0.1 f/cc standard reflects the need for careful monitoring of air quality in workplaces where asbestos is present, ensuring that measures are put in place to maintain exposure levels at or below this threshold.

The other options represent higher exposure limits that do not align with established safety standards in occupational health for asbestos. By adhering to the 0.1 f/cc standard, employers can better protect the health and safety of their workers who may come into contact with asbestos in their environments.
