Which item is NOT a suitable means of isolating an area during abatement?

During asbestos abatement, isolating the work area is critical to prevent exposure and contamination. Running air conditioning is not a suitable means of isolating an area because it can circulate air and potentially spread asbestos fibers to other parts of a building. This action contradicts the goal of maintaining a contained and controlled environment for safe removal of hazardous materials.

In contrast, physical barriers, warning signs, and tape with sheets are effective isolation methods. Physical barriers can prevent unauthorized access, warning signs inform others in the vicinity of the hazards present, and tape and sheets can seal off windows and doors to contain asbestos fibers, minimizing the risk of dispersal. Proper isolation techniques are essential for protecting both the workers and the general public during asbestos abatement activities.
