In selecting dust swipe sampling locations, which option best describes the sampling scope?

• A. Near hazard areas where treatment was done
• B. Nearby high traffic areas
• C. Other areas selected by inspector
• D. All of the above

Answer: (D)

Dust swipe sampling needs to be broad enough to capture where lead dust could be present and moved around in a space. Sampling near areas where treatment was done targets potential residual contamination at the source, helping verify that cleanup was effective. Including nearby high-traffic areas addresses the way dust can migrate and accumulate where people and activities disturb the space. Allowing the inspector to select other areas as needed adds flexibility to ensure the sampling plan covers locations that might not be obvious but could still affect exposure, depending on the room layout and activities. Together, these elements provide a complete picture of potential dust contamination, which is why all of the above is the best approach.
