What class of asbestos work is considered awareness-level work involving maintenance activities?

The correct answer is Class IV, which represents awareness-level work involving maintenance activities related to asbestos. In this context, Class IV work includes custodial and maintenance tasks that may involve the disturbance of asbestos-containing materials, but the key is that individuals performing this work are not required to remove or encapsulate asbestos.

Workers at this level are typically trained to recognize asbestos-containing materials and understand the safety measures necessary to prevent exposure. This includes procedures for maintaining and handling asbestos materials safely. Since the work is related to maintenance activities, the focus is on minimizing the potential for disturbance and ensuring safety rather than on extensive removal or mitigation efforts.

Understanding the classification system is important for distinguishing the levels of regulatory requirements and safety measures associated with asbestos work; Class I involves significant removal activities, Class II pertains to specific non-friable asbestos materials, and Class III covers repair and maintenance work that disturbs asbestos. Class IV is specifically tailored for awareness, emphasizing the recognition and safe handling of materials rather than extensive intervention.
