Under the AHERA regulations, which of the following is NOT included in an AHERA survey?

The correct answer is roofing felt, which is not included in an AHERA survey. AHERA, or the Asbestos Hazard Emergency Response Act, mandates inspections for asbestos-containing materials (ACM) in schools, focusing primarily on those materials that generally present a significant risk during building maintenance and repair.

Surfacing materials, thermal system insulation, and miscellaneous ACM are all types of materials that are commonly found in school buildings and are typically assessed during an AHERA survey. Surfacing materials may include coatings or finishes on ceilings, walls, and floors, which could easily release asbestos fibers when disturbed. Thermal system insulation is also a critical focus, as it is used to insulate pipes and ducts, often containing asbestos. Miscellaneous ACM covers a range of materials that could also pose a risk, such as acoustic tiles, textured paints, and certain types of floor tiles, which are often included in surveys to ensure a comprehensive assessment of potential asbestos hazards.

Roofing felt, on the other hand, is not a primary focus of these surveys under AHERA regulations. While it may contain asbestos, it is generally not categorized alongside the materials of greatest immediate concern in typical school environments. This distinction helps to streamline the survey process, focusing on the materials that are more likely to
