Environmental Protection Agency (EPA) Lead Risk Assessor Practice Exam

What conditions must be present to determine a friction surface hazard?

1. LBP, in contact with another building component, and evidence of damage

2. Visible wear and tear

3. Presence of various chemicals

4. Moisture and humidity

The correct answer is: LBP, in contact with another building component, and evidence of damage

To determine a friction surface hazard, specific conditions must be met to ensure that lead-based paint (LBP) poses a risk due to friction. The correct option emphasizes the necessity of LBP being in direct contact with another building component, which is critical because friction surfaces are often found where two materials rub against each other. This wear can lead to the release of lead dust or chips, thus increasing the risk of exposure. Evidence of damage is also vital; it signifies that the painted surface has deteriorated in a way that could contribute to lead hazards. For instance, peeling or chipping paint where there is physical contact can create a pathway for lead exposure through ingestion or inhalation of lead particles. While visible wear and tear, the presence of various chemicals, and moisture and humidity can influence overall hazard assessments, they do not specifically identify friction surface hazards. They may denote general deterioration or environmental conditions but do not address the direct mechanics of friction that impact lead exposure risk. Thus, the combination of lead-based paint contact and evidence of damage is essential for correctly assessing the potential for a friction surface hazard.
