What is the threshold limit value (TLV) for asbestos exposure?

The threshold limit value (TLV) for asbestos exposure is set at 0.1 fibers per cubic centimeter of air over an 8-hour workday. This standard reflects the permissible exposure limit established to protect workers from the harmful effects of asbestos, which can lead to serious health issues, including lung cancer and mesothelioma.

Setting the TLV at this specific level is based on extensive research into the health risks associated with asbestos fibers. The 8-hour workday framework is standard in occupational health guidelines, focusing on protecting individuals during typical working hours. By establishing such a limit, regulations aim to minimize the risk of adverse health outcomes among workers who may be exposed to asbestos in industrial settings.

The other options present various fiber concentrations, but they do not align with the established TLV guidelines. Thus, option B accurately captures the current regulatory standard for asbestos exposure in the workplace.
