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

During a Lead Hazard Screen, how many dust wipe samples should be collected from the entry area?

1. 1

2. 2

3. 3

4. 4

The correct answer is: 1

In a Lead Hazard Screen, the protocol for collecting dust wipe samples from the entry area specifies that only one sample should be collected. This is based on the guidance provided by environmental agencies which aim to streamline the assessment process while still gathering sufficient data to evaluate lead hazards. Collecting a single sample allows for a focused examination of lead dust levels in high-traffic areas such as entryways, where exposure risks may be greater due to external contamination being tracked into living spaces. The decision to limit the number of samples is rooted in efficiency and practicality, balancing the need for reliable data with the resources required for sample collection and analysis. Additionally, by concentrating on key areas such as the entryway, assessors can minimize disruption while still effectively identifying potential lead dust hazards.
