Define asbestos-containing material (ACM) as used in compliance with OSHA and AHERA guidance.

• A. Any material that is known to be asbestos-free.
• B. Any material that contains asbestos or is presumed to contain asbestos and is identified as ACM by testing or knowledge of its content.
• C. Any material that has asbestos fibers visible to the naked eye.
• D. Any material labeled as asbestos-containing in product packaging.

Answer: (B)

ACM means a material that contains asbestos or is presumed to contain asbestos, and it is identified as ACM by testing or knowledge of its content. This aligns with OSHA and AHERA because the material is treated as hazardous whenever there is confirmed asbestos content or a well-supported suspicion based on what the material is and how it’s used. The determination comes from actual lab analysis showing asbestos, or from documented knowledge that the material typically contains asbestos and that content is applicable to the specific item. It’s not about seeing fibers with the naked eye, and it isn’t just about labeling alone unless that label reflects verified content or established knowledge. This approach ensures proper protection, containment, or removal actions are taken for materials that truly contain asbestos or are reasonably presumed to contain it.
