Asbestos Hazard Emergency Response Act (AHERA) Certification Practice Exam

What does OSHA classify the safe exposure limit of asbestos as?

1. 0.1 fibers per cubic centimeter

2. 1 fiber per cubic meter

3. There is no safe amount

4. 50 fibers per cubic inch

The correct answer is: There is no safe amount

The correct answer reflects OSHA's position on asbestos exposure, which is that there is no safe level of asbestos fibers that can be inhaled without risk of developing serious health issues, including asbestosis, lung cancer, and mesothelioma. This stance is rooted in extensive research and epidemiological studies that have shown even low levels of exposure can pose significant health risks over time. Recognizing that asbestos fibers can remain airborne, accumulate in the lungs, and lead to delayed health effects, OSHA emphasizes the necessity of minimizing exposure as much as possible. This commitment to worker safety underlines the importance of proper precautions and regulations when working in environments where asbestos may be present. The other options suggest specific exposure limits that imply a degree of safety, which does not align with current understanding and regulatory guidelines stating that no level of asbestos exposure can be considered completely safe. This reinforces the focus on stringent safety measures aimed at reducing asbestos risks in occupational settings.
