RACM includes which of the following?

• A. Any friable ACM (>1%) or any Category I or II materials that become friable
• B. Only friable ACMs
• C. All asbestos-free materials
• D. Only Cat II materials

Answer: (A)

RACM means Regulated asbestos-containing material, and it covers the materials that pose a higher exposure risk when disturbed. Any material that is already friable and contains asbestos is RACM because it can release fibers easily. In addition, nonfriable asbestos-containing materials are RACM only if they are categorized as Category I or II and are likely to become friable—or are already friable—through standard handling, cutting, sanding, grinding, or other work. So the best description is: all friable ACM, plus Category I or II nonfriable ACM that will become friable. The other options miss either the friable materials, or the conditional nonfriable ones, or they include asbestos-free materials.
