What does the term “asbestos-containing material” (ACM) refer to?

The term “asbestos-containing material” (ACM) specifically refers to any material that contains more than 1% asbestos by weight. This definition is crucial for regulatory and safety purposes, as it helps determine which materials require special handling and management due to the potential health risks associated with asbestos exposure. Identifying materials with this threshold is important for effective risk assessment and remediation efforts.

Materials can contain asbestos in various forms, including both visible and non-visible aspects, and may be found in products not solely composed of asbestos. The significance of this definition lies in establishing a clear standard for identifying materials that can pose health risks, which informs safety guidelines and regulations governing their use, removal, and disposal.
