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

In a multi-family setting built before 1960, what is the recommended number of units to sample?

1. Five units

2. Ten units

3. Fifteen units

4. Two units

The correct answer is: Ten units

In a multi-family setting built before 1960, the recommended protocol is to sample a minimum of ten units for lead-based paint risk assessment. This guideline helps ensure that the sampling adequately represents the potential risk of lead exposure across a substantial portion of the building. Sampling a larger number of units increases the likelihood of detecting lead-based paint hazards and provides a more comprehensive risk assessment of the entire property. Additionally, this approach allows for a better understanding of the potential presence of lead dust and deteriorating paint across different units, which is crucial for developing effective remedial strategies. By assessing at least ten units, it becomes possible to identify systemic issues related to lead exposure in multi-family residences, which can significantly impact public health, particularly for vulnerable populations such as young children.
