Areas to take dust swipe samples?

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

Answer: (A)

Dust swipe sampling is used to assess lead dust levels on surfaces where children touch or where dust tends to accumulate. To get a reliable picture, you don’t limit sampling to a single spot. Sampling near hazard areas where treatment was done is important because those sites are most likely to shed residual lead dust after work. Sampling in nearby high-traffic areas captures the areas where dust is more likely to be tracked and spread through daily activities. And the inspector may select other areas based on the building layout, occupancy, and observed dust patterns to fill gaps and ensure the assessment reflects real exposure risk. Because all these areas provide useful information about the spread and burden of lead dust, choosing all of the above is the most accurate approach.
