Which product types are identified as ACM categories in AHERA inspections?

• A. Thermal System Insulation; Surfacing; Miscellaneous
• B. Paint; Caulk; Sealant
• C. Tile; Grout; Mortar
• D. Plastic piping; Glass fiber; Drywall

Answer: (A)

AHERA inspections categorize asbestos-containing materials into three broad groups: Thermal System Insulation, Surfacing materials, and Miscellaneous. Thermal System Insulation covers insulation around pipes, ducts, and boilers. Surfacing materials include sprayed-on or troweled coatings that form a surface texture, such as acoustical plaster or fireproofing. Miscellaneous covers all other ACM not in the first two groups, like various coatings, roofing products, flooring, gaskets, and cementitious materials. This three-category framework is used to organize where ACM might be found and how it’s managed during inspections, so listing those three categories together matches the AHERA approach. The other options name specific product types rather than the official category names used in AHERA inspections.
