If dust-lead levels are equal to or greater than the applicable standards, what is the recommended action?

• A. The client should order repeated cleaning
• B. All surfaces represented by the failing samples must be re-cleaned
• C. The clearance area should be kept secure until clearance is achieved
• D. The sampling technician should re-inspect before dust testing

Answer: (B)

When dust-lead wipe results exceed or meet the standard, the next necessary step is to address the exact surfaces that produced the failing results by re-cleaning them. This targeted cleaning focuses on removing the sources of elevated lead dust so the area can be retested and reach clearance. After re-cleaning those surfaces, a re-sampling is required to verify that the levels are now compliant.

Other options miss the essential targeted action: simply ordering more cleaning without specifying which surfaces, focusing on securing the area rather than cleaning, or re-inspecting before testing. The key is to re-clean the surfaces represented by the failing samples to drive the area back into compliance.
