An abbreviated test can be performed when

• A. The owner agrees; all components tested are the same in each room equivalent; the component tested is positive for lead-based paint in the first five rooms tested.
• B. The owner disagrees; tests vary by room; the component tested is negative
• C. The test is performed only on ferrous metals
• D. The building has no lead paint

Answer: (A)

Abbreviated testing is allowed when you can reasonably extend a finding from a small, representative set to other similar components across rooms, and the owner agrees to a shortened approach. Here, the same type of component is tested in each room, so if the first five rooms show lead-based paint on that component, you can infer a high likelihood of lead presence in the remaining rooms with the same component. The owner’s consent is required because this shortcut changes how the assessment is conducted and reduces the amount of testing performed. This approach avoids duplicative sampling while still giving a valid indication of lead presence across comparable surfaces. The other scenarios don’t fit: without the owner’s agreement, you can’t use the abbreviated method; if tests vary by room, you can’t assume uniformity across all rooms; a negative result in the initial rooms wouldn’t justify extrapolating absence to other components; and testing only ferrous metals or a building with no lead paint wouldn’t align with the purpose of using an abbreviated protocol.
