The inspector also tests soil and dust for lead contamination as part of a clearance test.

• A. False
• B. True
• C. Only soil is tested
• D. Only dust is tested

Answer: (B)

Clearance testing verifies that the cleanup has reduced lead hazards to acceptable levels. It typically includes collecting dust wipe samples from interior surfaces and soil samples from outdoor areas around the work zone because exposure can come from both sources. Dust inside can be ingested or inhaled, and soil outdoors can contribute to exposure if tracked indoors or used by children for playing. By testing both media, the inspector ensures cleanup meets the required safety thresholds in areas most likely to pose risk. If results exceed standards, additional cleaning or corrective work is needed before the space is considered clear. This is why testing both soil and dust is part of a clearance test.
