After reducing lead hazards, who must perform clearance testing?

• A. Certified inspector
• B. Risk assessor
• C. Certified inspector or risk assessor
• D. Homeowner

Answer: (C)

Clearance testing verifies that a space cleaned up after reducing lead hazards meets the approved safety levels before people return. After the work, this sampling must be done by someone who is certified in lead-based paint assessment—either a certified inspector or a certified risk assessor. These professionals are trained to collect dust wipe samples (and sometimes air samples), have them analyzed by an accredited lab, and interpret the results against the required clearance standards. A homeowner isn’t qualified to perform this testing, and a non-certified person wouldn’t be able to ensure the results meet regulatory thresholds. So the responsible path is that either a certified inspector or a certified risk assessor conducts the clearance testing.
