Posting of asbestos abatement warning signs is required:

Posting of asbestos abatement warning signs is required:

• A. At all entrances to the work area where airborne concentrations of asbestos may exceed ambient background levels
• B. Only at the main entrance
• C. In break rooms
• D. On the exterior fence

Answer: (A)

Posting asbestos abatement warning signs at all entrances to the work area where airborne concentrations may exceed ambient background levels is essential because anyone approaching or entering the site needs immediate notice of the hazard and the required precautions. If signs are only placed at a single point, other entry points remain unmarked, increasing the risk of unprotected exposure. The exterior fence or break rooms aren’t reliable boundaries for the work area, and they don’t guarantee that every access point is clearly labeled. By placing signs at every entrance where the hazard could be present, you ensure that access is controlled and workers and visitors can follow the necessary controls and PPE before entering.
