Environmental Protection Agency (EPA) Model Lead Based Paint Risk Assessor Practice Test

In a multi-family unit, how are dwelling units selected for sampling?

1. By random selection from a list of all tenants

2. Through a walk-through survey focusing on high-risk areas

3. Using historical data from previous assessments

4. By consulting with property managers

The correct answer is: Through a walk-through survey focusing on high-risk areas

In a multi-family unit, selecting dwelling units for sampling is often done through a walk-through survey that focuses on high-risk areas. This method allows assessors to make informed decisions about which units are more likely to contain lead-based paint hazards, based on visual cues and the conditions found in various parts of the property. Conducting a walk-through survey enables the assessment team to identify factors such as the age of the building, the condition of painted surfaces, and any signs of deterioration, which are critical for understanding lead exposure risks. This targeted approach can be more efficient and effective than random selection, as it prioritizes units that are at a higher risk of containing lead hazards due to their specific circumstances, such as children living there or historical factors related to lead paint use. By focusing on high-risk areas, the risk assessor can ensure that the sampling is relevant and addresses the most pressing concerns regarding lead exposure in the residential setting.
