What is the main goal of class IV works?

The main goal of class IV works is to provide maintenance without disturbing asbestos-containing material (ACM). This classification is specifically designed for tasks that involve general maintenance and housekeeping activities in areas where ACM is present but not being actively removed. The focus here is on ensuring that the integrity of the ACM remains intact and that no airborne fibers are released during maintenance processes. This approach is crucial for protecting workers and facilitating safety in environments where asbestos is present, as it helps to mitigate risk without the need for extensive or intrusive removal operations.

While addressing other options, complete removal of all ACM represents a more invasive approach typically undertaken during class I or II work, which may not be necessary or practical in all scenarios. Monitoring exposure is essential but falls more under health and safety practices rather than a primary goal of class IV work. Encapsulating ACM is a management strategy that would be categorized in a different class depending on the context and materials involved. Thus, the primary focus of class IV work is on maintenance while preserving the existing ACM and minimizing any potential risks.
