What should be the minimum size of sections when removing ACM from duct and pipe work?

The guideline for the minimum size of sections when removing Asbestos Containing Materials (ACM) from duct and pipe work is that areas should be manageable and generally set to a minimum of 3 feet. This size strikes a balance between ensuring that sections are easy to handle for workers while also minimizing the amount of material being disturbed at any one time, which is crucial for maintaining safety and managing exposure to asbestos fibers.

Cutting sections that are too large can lead to challenges in handling, increasing the risk of accidental damage or exposure during the removal process. On the other hand, sections that are much smaller may not be practical for the removal logistics and can increase the time and effort required for the task. Therefore, defining a minimum size of 3 feet helps to optimize both safety and efficiency during ACM removal operations.

The other options suggest different maximum sizes or handling strategies that do not align with these safety and efficiency considerations.
