How should a lead clearance technician respond if a post-abatement wipe sample exceeds the clearance criteria?

• A. Ignore and report as cleared.
• B. Seek exemption from standards.
• C. Re-clean area according to protocol and resample until surfaces meet criteria.
• D. Replace the surface with new material.

Answer: (C)

When a wipe sample after abatement tests above the clearance criteria, you can’t declare the area clear. The proper response is to re-clean the area using the approved protocol, then take another wipe sample to verify that the surfaces now meet the criteria. This cycle continues until the results are within the acceptable limit. This approach directly addresses the residual contamination and provides documented evidence that the cleanup was effective, protecting occupants and satisfying regulatory requirements. Ignoring the exceedance would leave a safety risk, seeking an exemption bypasses safeguards, and replacing the surface is not the standard remedy unless the surface itself is unusable.
