Grouping adjacent components is allowed when they have what?

• A. They must have different painting histories.
• B. They have the same painting history.
• C. They are on different floors.
• D. They are different substrates.

Answer: (B)

Grouping adjacent components is allowed when they have the same painting history, meaning they were painted with the same coating at the same time. This ensures the lead-based paint status and the required containment and cleanup steps are the same across all those surfaces, so you can handle them together efficiently without introducing additional risk. If painting histories differ, grouping could mix surfaces with different lead risks and containment needs, increasing potential for dust spread or improper waste handling. The other factors, like being on different floors or having different substrates, don’t determine the lead coating status and thus aren’t the basis for grouping.
