Single surface wipe samples provide data for what?

Single surface wipe samples provide data for what?

• A. They measure leaded dust levels at a specific location
• B. They measure only exterior dust
• C. They replace composite samples
• D. They require three times the personnel

Answer: (A)

Single surface wipe samples are used to measure leaded dust at a specific location. By wiping a defined area of a surface and analyzing the wipe, you obtain the lead loading for that exact spot, which helps determine whether that surface poses a lead exposure risk. This method provides location-specific data, rather than a broad average for an entire room or exterior area. It does not replace composite samples, which combine multiple surfaces to estimate an average across an area, and it doesn’t inherently require more personnel.
