For exterior abatement, a visual inspection for dust and debris should include which surfaces?

• A. Interior walls and ceilings only
• B. All horizontal surfaces in the outdoor living space, and at the dripline or next to the foundation below any exterior surface abated
• C. Only the roof surfaces
• D. None; visual inspection is not required

Answer: (B)

Dust and debris from exterior abatement can travel and settle beyond the treated area, so the visual check must cover outdoor horizontal surfaces in the exterior living space and also at the dripline or adjacent foundation below any exterior surface that was abated. Horizontal surfaces are where wind-blown dust and gravity cause residues to accumulate, including decks, patios, walkways, and other flat outdoor areas, while the dripline and foundation areas are common deposition points where debris can fall or migrate from the abated surface. Inspecting these areas helps ensure that no lead-contaminated dust or debris remains accessible or capable of spreading to people or indoor spaces. Interior walls and ceilings, or only inspecting roof surfaces, would miss these outdoor deposition points, and saying none is required would ignore a key risk.
