Asbestos Hazard Emergency Response Act (AHERA) Certification Practice Exam

Which of the following is NOT a method by which schools can respond to asbestos?

1. Encapsulation

2. Enclosure

3. Replacement

4. Repair and Removal

The correct answer is: Replacement

The correct answer is that replacement is not a recognized method by which schools can respond to asbestos. In the context of asbestos management in schools, effective strategies focus on containment, management, and remedial actions that do not necessarily involve removing the asbestos-containing materials entirely. Encapsulation involves applying a sealant over asbestos materials to prevent the release of fibers, thus effectively managing the risks associated with them. This method is typically used when the asbestos is in good condition and not likely to be disturbed. Enclosure is another method where a physical barrier is constructed around the asbestos materials. This isolates them from the occupants, preventing exposure while allowing the materials to remain in place if they are intact and undisturbed. Repair and removal are also vital responses, where damaged asbestos materials can be fixed or safely removed, respectively. However, outright replacement of asbestos materials is not a standard method outlined in AHERA guidelines. Instead, the focus is on management strategies that ensure safety without unnecessary removal, which can sometimes pose a greater risk if not handled correctly.
