Which approach is allowed to denote exact ACM locations when drawings are not used?

• A. Blueprints
• B. Signage plan
• C. Written description
• D. Photographs

Answer: (C)

When drawings aren’t available, the precise way to indicate where asbestos-containing materials are located is with a detailed written description. This lets you specify exact locations using concrete identifiers like room numbers, specific areas within a room, and fixed references such as distances from walls, ceilings, or fixtures. A well-crafted written description might say something like: “in the ceiling plenum above the northeast corner of Room 204, 1.2 meters below the ceiling surface, adjacent to the air diffuser,” or “behind the chase in the mechanical room, on the left-hand side of the vertical conduit.” This approach is unambiguous and easy to audit, and it can be updated if conditions change. Blueprints and signage plans provide visual schemes, but without the actual drawings, they don’t convey precise, locational detail in a way that’s directly usable on site. Photographs can show what something looks like but often lack exact coordinates or context needed to relocate the material reliably. The written description fills that gap, offering a clear, repeatable method to denote exact ACM locations when drawings aren’t used.
