Which of the following best describes class III works?

Class III works specifically encompass repair and maintenance operations where asbestos-containing materials (ACM) may be disturbed. This classification is critical because it recognizes that while the primary intent may not be the removal of asbestos, the work involves activities that have the potential to disturb ACM.

This is essential for ensuring worker safety, as even minor disturbances can release asbestos fibers into the air, presenting health risks. In such operations, workers must adhere to strict safety protocols to minimize exposure and manage the risks associated with handling or being near ACM.

Other classifications do exist in asbestos work—such as Class I for complete removals and Class II for removal of specific materials—but Class III focuses on the day-to-day repairs and maintenance tasks. Understanding this distinction helps workers and supervisors implement appropriate safety measures tailored to the specific risks of each class.
