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

Which of the following is NOT a cause of Lead Paint Hazards?

1. Leaking roofs

2. Deteriorated paint

3. Dust

4. Obstructed airflow

The correct answer is: Obstructed airflow

The correct answer points to obstructed airflow as not being a direct cause of lead paint hazards. Lead paint hazards primarily arise from conditions that expose individuals to lead dust, chips, or fumes, which can be inhaled or ingested, leading to lead poisoning. Deteriorated paint is a significant source of lead hazards, particularly in older properties where lead-based paint was commonly used. When paint deteriorates, it can create lead dust and chips that can contaminate the environment. Similarly, dust itself can be a substantial contributor to lead exposure, especially when it settles in areas where children and pets might disturb it, causing it to become airborne again. Leaking roofs can contribute indirectly to lead hazards by creating conditions favorable for paint deterioration through moisture, which can lead to peeling and chipping of lead-based paint. Obstructed airflow does not directly contribute to the presence or creation of lead hazards. While adequate airflow is essential for overall indoor air quality and to prevent moisture buildup, its obstruction does not cause lead paint to deteriorate or create lead dust. Therefore, it stands apart from the other options, all of which are connected to the direct exposure or deterioration associated with lead-based paint risks.
