What method should an AHERA inspector use to check for debris and dust?

Using a damp cloth and flashlight is an effective method for an AHERA inspector to check for debris and dust. This approach allows the inspector to physically wipe surfaces, helping to capture any loose particles that may contain asbestos. The damp cloth minimizes the chance of airborne fibers being released during the inspection, providing a safer way to collect samples of debris. Additionally, utilizing a flashlight enhances visibility, allowing the inspector to see areas that may be otherwise overlooked, especially in dimly lit spaces or where dust accumulation might not be immediately apparent.

Other methods, while valuable in specific contexts, do not provide the same level of surface examination. For instance, using a vacuum cleaner with a HEPA filter is beneficial for clean-up purposes but might not effectively reveal hidden debris or allow for direct sampling of materials. Visual inspection with natural light can identify some issues but lacks the physical interaction necessary to assess debris presence accurately. Utilizing portable air sampling devices primarily monitors airborne asbestos fibers rather than directly inspecting surfaces for dust accumulation. Therefore, employing a damp cloth and flashlight offers a thorough and safe inspection of potential asbestos debris in a building.
