Class IV works are primarily concerned with which of the following?

Class IV asbestos work primarily involves activities where there is contact with asbestos-containing materials (ACM) but without disturbing them. This classification is focused on situations where the safety and integrity of the asbestos material are maintained. Workers performing Class IV tasks need to ensure that they minimize any risk of releasing asbestos fibers into the air, which could pose a hazard to health.

This type of work requires awareness and adherence to safety protocols, but it does not entail the removal or significant disturbance of the ACM, which would require different classifications with more stringent controls and remediation practices. It is crucial for workers to understand the classification and types of tasks associated with asbestos to ensure they follow the correct safety measures and regulations in their work environment.

In contrast, other classifications involve more direct manipulation or removal of ACM, which necessitates different training and safety precautions.
