Which statement about testing a location is true?

• A. To determine the paint color.
• B. To take an XRF reading or paint-chip sample from a specific area on a testing combination.
• C. To identify room equivalents.
• D. To group adjacent components.

Answer: (B)

Testing a location means getting a measurement from a defined spot on the surface to learn whether lead is present and at what level. The best approach is to take an XRF reading or a paint-chip sample from a specific area on a testing combination. XRF provides a quick, non-destructive measure of lead content in the paint, while a paint-chip sample offers material for lab analysis to confirm results or to check for different layers. This spot-specific data matters because lead content can vary across a surface, and making decisions about protection or remediation relies on knowing exactly what’s in that particular area. The other ideas—determining paint color, identifying room equivalents, or grouping adjacent components—don’t directly assess lead content at a defined location.
