Asbestos Hazard Emergency Response Act (AHERA) Certification Practice Exam

What is the current OSHA PEL for asbestos exposure?

1. 0.05 fibers per cubic centimeter

2. 0.1 fibers per cubic centimeter

3. 1 fiber per cubic centimeter

4. 10 fibers per cubic centimeter

The correct answer is: 0.1 fibers per cubic centimeter

The current Occupational Safety and Health Administration (OSHA) permissible exposure limit (PEL) for asbestos is set at 0.1 fibers per cubic centimeter (f/cc) of air over an 8-hour time-weighted average. This limit is designed to protect workers from the harmful effects of asbestos exposure, which can lead to serious health issues such as asbestosis, lung cancer, and mesothelioma. The 0.1 f/cc standard reflects OSHA's commitment to minimizing the risk of exposure to asbestos in occupational settings, particularly in industries where asbestos is still present or may be disturbed. By setting this limit, OSHA aims to ensure that employers implement necessary safety measures and protocols to reduce airborne asbestos fibers and protect the health of workers. The value chosen is significant because it indicates the concentration of asbestos fibers allowed in the air, putting a focus on maintaining a safer work environment. Employers are required to monitor asbestos levels and take action if the concentration exceeds this established limit, which reinforces the importance of adherence to safety regulations and practices in workplaces that involve asbestos.
