What indicates potential for significant damage according to AHERA?

The selection of the option indicating that the material is subject to major or continuing disturbance aligns with the requirements set forth by the Asbestos Hazard Emergency Response Act (AHERA). Under AHERA, the risk of asbestos-containing material causing significant damage is directly linked to the extent of disturbance it experiences. When materials containing asbestos are frequently disturbed—whether through demolition, reconstruction, or ongoing maintenance—fibers can be released into the air, leading to potential health hazards for occupants.

In contrast, materials that are undisturbed or properly sealed do not pose the same level of risk. Undisturbed materials mean that they are intact and not at risk of releasing fibers, while properly sealed materials are contained in a manner that prevents the release of asbestos fibers into the environment.

Similarly, materials located in isolated areas generally indicate reduced risk as they are less likely to encounter activities that could harm them or lead to fiber release. Thus, continued disturbance is a key indicator of potential for significant damage according to AHERA, solidifying why this choice is the correct answer.
