Which statement about clearance testing is accurate?

• A. Clearance testing is limited to visual inspection only
• B. The inspector tests soil and dust for lead contamination as part of a clearance test
• C. Clearance testing does not involve any laboratory analysis
• D. Lead-based paint is not considered during clearance testing

Answer: (B)

Post-abatement clearance checks verify that the lead hazard has been reduced to acceptable levels by analyzing collected samples in a lab. This process uses laboratory analysis to measure lead in dust on interior surfaces and, when appropriate, in surrounding soil. The idea is to confirm that both indoor dust and exterior soil (if work could have disturbed it) meet the required standards before reoccupancy. Visual inspection alone can’t prove safety, and relying on no lab analysis would leave lead levels unknown. Including soil sampling when exterior contamination could be a pathway completes the clearance picture, which is why testing both soil and dust is the correct approach.
