Class IV tasks typically focus on which of the following?

Class IV tasks primarily emphasize cleaning and maintaining areas where asbestos-containing material (ACM) is present without causing any disturbance to the material itself. This is essential because the goal of Class IV work is to minimize any risk of exposure to asbestos fibers that may be released if the ACM were to be disturbed.

In settings where asbestos is present, it is crucial to ensure that surfaces remain clean and that ACM is managed properly to prevent any potential hazards associated with asbestos exposure. Workers involved in Class IV tasks are trained to understand the safe methods of maintaining these environments, ensuring that any necessary maintenance or cleaning does not compromise the integrity of the ACM.

The other options reflect practices that either involve higher risk activities or require more intensive intervention, which fall outside the scope of routine cleaning and maintenance associated with Class IV tasks. For example, assessing exposure to ACM or completely removing surfacing materials would require a much more significant level of training and regulatory compliance, often classified under higher classes of asbestos work.
