BEN Lead Paint Risk Assessor Practice Test

Encapsulation is not an appropriate method for controlling lead dust hazards on a friction and impact surface. This is because encapsulation involves covering the lead-containing material with a protective barrier to prevent exposure; however, on surfaces where friction and impact occur—such as windowsills or door frames—the encapsulating layer can wear away over time due to the constant movement and stress on the surface. This degradation can result in the release of lead dust, creating potential exposure risks.

In contrast, sealing, enclosure, and paint removal are more effective strategies for addressing lead dust hazards on these types of surfaces. Sealing involves applying a specialized coating that adheres well to the lead paint surface, preventing the release of dust. Enclosure means constructing a physical barrier around the lead hazard, keeping it contained and preventing contact. Paint removal is the most effective long-term solution as it eliminates the lead threat entirely.
