In a large multi-family housing unit, how is the sample collection adjusted for spaces over 2000 sqft?

In a large multi-family housing unit, it is necessary to adjust sample collection based on the size of the space when it exceeds 2000 square feet. The correct answer specifies that for each additional 2000 square feet, one extra floor and one extra window sample should be collected. This adjustment is crucial because larger spaces may present varied conditions that can affect lead exposure risks. By collecting additional samples, the assessor is able to gather a more representative dataset that reflects the potential lead hazards throughout the entire unit.

The rationale behind this approach is to ensure that lead risk assessments are accurate and comprehensive. More samples help to identify specific areas where lead may be present, increasing the likelihood of detecting problem areas that might not be apparent with a smaller sample size. This thorough assessment is fundamental in making informed management decisions about lead hazards in larger multi-family units.
