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

The permissible exposure limit (PEL) for asbestos, as established by regulatory agencies such as the Occupational Safety and Health Administration (OSHA), is set at 0.1 fiber per cubic centimeter of air over an eight-hour workday. This limit is based on extensive research regarding the health risks associated with asbestos exposure, which can lead to serious conditions such as mesothelioma and asbestosis.

Setting the PEL at 0.1 fibers per cubic centimeter is a significant measure aimed at protecting workers exposed to asbestos in various industries. It reflects a balance between allowing necessary work with asbestos while minimizing risk to human health. This standard also plays a critical role in guiding asbestos monitoring and compliance efforts, ensuring that workplaces adhere to safety measures that can reduce exposure levels for employees. Other limits provided in the options do not align with this established standard and therefore would not be considered permissible exposure levels.
