What is considered significantly damaged material by AHERA?

• A. Damaged ACBM that is extensive but not severe.
• B. Damaged ACBM where the damage is extensive AND severe.
• C. Any crack in ACBM.
• D. Only surface staining.

Answer: (B)

The key idea is that AHERA defines “significantly damaged” asbestos-containing material as damage that is both extensive and severe, meaning it could readily release fibers if disturbed. When damage is widespread and badly deteriorated, the material presents a high risk and typically requires removal or more stringent remediation under AHERA rules. If damage is only widespread but not severe, or if there are just small cracks or surface staining, it doesn’t meet the threshold for significant damage and can often be managed with routine maintenance or encapsulation rather than removal.
