A surface by surface investigation is used to determine the presence of which condition?

• A. Friction surface degradation only
• B. Dust levels only
• C. Lead-based paint inspection
• D. Interior moisture levels only

Answer: (C)

This question focuses on identifying where lead-based paint is present by inspecting each painted surface individually. A surface-by-surface inspection is the standard approach for a lead-based paint inspection because it maps out exactly which surfaces contain lead, allowing targeted remediation or containment. Inspectors typically screen with a portable XRF analyzer and may collect paint-chip samples for lab confirmation when needed. This method is about locating lead content on surfaces, not about measuring dust, moisture, or physical wear. Dust sampling, moisture testing, and assessments of friction or degradation address different hazards and uses, so they aren’t determined by a surface-by-surface lead inspection.
