In the dust sampling process, which statement is correct about handling the collected wipe?

• A. The folded wipe is placed in the sampling tube
• B. The wipe is discarded
• C. The wipe is left on the surface
• D. No container is used; analysis is done on the raw surface

Answer: (A)

Proper containment and handling of the wipe sample is essential to preserve sample integrity and ensure accurate analysis. After collecting dust with the wipe, folding it helps keep the collected material on the wipe and makes it easy to fit into a sterile container. Placing the folded wipe into the sampling tube protects the sample during transport, minimizes contamination from the environment, and maintains the chain of custody for lab processing. Leaving the wipe on the surface risks incomplete collection or recontamination; discarding it would lose the sample; and not using a container would make transport and analysis noncompliant with standard procedures.
