If drawings are not used, which form of documentation can be used to denote ACM locations in plans?

• A. Verbal summary
• B. Photographs only
• C. Labeling on doors
• D. Diagrams

Answer: (D)

When drawings aren’t used, a visual map is needed to show where asbestos-containing materials are located. Diagrams provide that clear spatial reference by presenting a simplified representation of the space with symbols that mark the ACM locations, along with a legend and scale. This lets anyone reading the document understand exactly where to find the materials within rooms, corridors, or structural elements, which is essential for planning work, safety procedures, and follow-up inspections.

Verbal summaries describe locations in words but don’t convey where they sit in the layout. Photographs capture specific instances but don’t relate those spots to the overall plan. Labeling on doors might point to individual features but doesn’t give a cohesive view of the distribution across the building. Diagrams bridge that gap by combining location context with easy-to-interpret markers, making the information actionable for contractors and safety personnel.
