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

When should a dust wipe be conducted?

1. After every renovation project

2. Before any assessment begins

3. After lead removal activities

4. Two composite samples should be taken

The correct answer is: Two composite samples should be taken

The correct approach to conducting a dust wipe is closely tied to specific practices that ensure the safety and regulatory compliance in environments where lead-based paint is a concern. Dust wipes are typically conducted after lead removal activities to assess the effectiveness of the lead abatement process. This is crucial because it provides a clear measure of whether any lead dust remains in the environment, thereby confirming that the remediation efforts were successful and that the space is safe for occupancy. In scenarios such as renovation projects, it's not only important to conduct dust wipes afterward, but also in various stages of assessment, particularly after activities known to disrupt lead-based paint. The emphasis on conducting wipes after such activities ensures that any potential hazards are accurately identified and managed, thus protecting occupants from exposure. While the option mentioning two composite samples suggests a method for comprehensive assessment, the primary focus is on the timing related to lead removal efforts rather than the sampling strategy itself. By ensuring dust wipes are conducted after lead removal, the assessment can correctly ensure a controlled environment free of hazardous lead contaminants.
