What does "asbestos-containing material" (ACM) refer to?

"Asbestos-containing material" (ACM) is defined as any material that contains 1% or more asbestos by weight. This threshold is significant because it establishes the regulatory limits for the handling, management, and disposal of such materials. In workplaces, particularly in the construction and renovation fields, recognizing ACM is crucial for ensuring safe practices and compliance with health regulations.

Correctly identifying ACM is vital for protecting workers and the environment from the hazards associated with asbestos exposure. Materials containing less than 1% asbestos are generally not classified as ACM and may not be subject to the same strict regulations or control measures. Therefore, understanding that the 1% threshold is what defines a material as ACM is essential for anyone working in environments where asbestos may be present.
