If dust wipe sample results exceed the clearance standards, what must be done?

• A. Recleaning of the affected areas
• B. Recleaning of the affected areas and resampling until clearance standards are met
• C. Recontamination and Rework of Non-Affected Areas
• D. Halting Work Until Next Inspection

Answer: (D)

When dust wipe results exceed the clearance standards, the immediate action is to halt work and hold the area until the next inspection. Stopping work is essential to prevent further spread of contamination and to give the team a formal moment to verify and address the issue. After the halt, the area is re-cleaned and re-tested, and work can resume only after the clearance criteria are met and the area passes the subsequent inspection. This approach protects workers and occupants and ensures the project only continues when the site is confirmed to be free of exceedances.
