What is the OSHA permissible exposure limit for asbestos over 8 hours?

The OSHA permissible exposure limit (PEL) for asbestos over an 8-hour workday is indeed set at 0.1 fibers per cubic centimeter (f/cc) of air. This limit is established to protect workers from the hazardous health effects associated with asbestos exposure, including lung diseases and cancers. The 0.1 f/cc standard reflects the understanding that even low levels of exposure can pose significant health risks, hence the need for stringent control measures in workplaces where asbestos is present.

This exposure limit is part of a broader regulatory framework that aims to minimize the risk of asbestos-related illnesses. The other values, while potentially relevant in discussions of workplace safety and exposure monitoring, do not represent the current OSHA standard for permissible exposure to asbestos. Understanding this limit is crucial for compliance with safety regulations and for ensuring the health and safety of those who may be exposed to asbestos in various occupational settings.
