New York State Asbestos Investigator Practice Exam

What is the asbestos excursion limit set at?

1. 0.5 fiber per cubic centimeter of air

2. 1.0 fiber per cubic centimeter of air

3. 0.75 fiber per cubic centimeter of air

4. 0.2 fiber per cubic centimeter of air

The correct answer is: 1.0 fiber per cubic centimeter of air

The asbestos excursion limit is established to protect workers from the harmful effects of asbestos exposure. This limit signifies the maximum allowable concentration of asbestos fibers in the air over a specified period, usually measured in fibers per cubic centimeter (f/cc). The correct limit of 1.0 fiber per cubic centimeter of air is set by regulatory agencies to ensure that individuals in workplaces where asbestos is present are not exposed to levels that could lead to health risks. This limit reflects thorough research on asbestos and its potential impact on human health, particularly concerning diseases such as asbestosis and mesothelioma. In the context of regulatory compliance and workplace safety standards, this excursion limit plays a crucial role. It allows for short-term exposure above the permissible limit, which is necessary for brief activities or tasks that may disturb asbestos. Proper monitoring and adherence to this limit help maintain safety in environments where asbestos is present. Understanding this limit is essential for professionals engaging in asbestos-related activities, as it underlines the importance of air quality monitoring and the implementation of safety measures to ensure the well-being of workers in potentially hazardous environments.
