Which of the following materials is classified as surfacing ACM?

The classification of surfacing asbestos-containing material (ACM) is based on specific characteristics and applications of materials that contain asbestos and are directly applied to surfaces for purposes such as fireproofing, insulation, or aesthetic finishes.

Paint containing asbestos qualifies as surfacing ACM because it is typically applied to surfaces as a protective or decorative coating. As such, when it deteriorates or is disturbed, it can release asbestos fibers into the environment, posing a risk of exposure. This characteristic of being directly applied to surfaces and intended for surface-level finishes is key to its classification as surfacing ACM.

In contrast, materials like asphalt shingles and ceiling tiles are categorized differently. Asphalt shingles, while they can contain asbestos, are considered roofing materials rather than surfacing materials directly applied for protective or aesthetic values. Ceiling tiles, although they can also be ACM, are primarily classified as encapsulated or non-friable materials rather than surfacing ACM since they are not typically applied as a detailed surface finish. Thermal pipes, which often have asbestos insulation, serve a functional purpose of thermal regulation rather than being classified as surfacing materials directly interactable at the surface level.

Understanding these classifications helps in managing and determining the appropriate safety measures for handling, removal, or abatement of ACM
