Which statement correctly contrasts Accessible vs Exposed in AHERA definitions?

• A. Accessible means disturbance requires permission; Exposed means disturbance is not allowed.
• B. Exposed means danger is imminent; Accessible means no risk.
• C. Accessible means disturbance is possible during normal use; Exposed means not concealed by barriers.
• D. Accessible and Exposed are the same concept.

Answer: (C)

Understanding how AHERA distinguishes these terms helps you see how they guide handling asbestos-containing material. Accessible means disturbance is possible during normal use—think of material that could be touched or damaged during routine maintenance or daily activities. Exposed means not concealed by barriers, so it’s visible or reachable without any protective enclosure, making it easier for occupants to encounter it. That’s why the stated pair is the best: it correctly separates the idea of potential disturbance during ordinary use from the absence of barriers that would hide the material. The other options mix in concepts like permission, imminent danger, or imply they’re the same, which doesn’t match how AHERA defines accessibility and exposure.
