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

Which of the following is a pro of building component replacement?

1. It permanently eliminates the source of lead exposure

2. It minimizes worker and resident exposure to leaded dust

3. It requires no construction work

4. It increases the overall building value

The correct answer is: It minimizes worker and resident exposure to leaded dust

The advantage of building component replacement is that it permanently eliminates the source of lead exposure. When components that may contain lead-based paint, such as doors, windows, or siding, are replaced, the existing lead hazards are removed from the environment. This approach effectively addresses the underlying risk of lead exposure, as it targets the actual source rather than merely managing the symptoms or potential exposure points. In contrast, while minimizing worker and resident exposure to leaded dust is important, it does not capture the full benefit of replacing components. Furthermore, the process of building component replacement inherently involves construction work, and while this might temporarily create some lead dust issues if not managed properly, the ultimate goal is to eradicate lead sources altogether, thus enhancing safety. Lastly, while replacing components may contribute to an increase in property value, this is not the primary motivation for lead hazard control and is more of a potential secondary benefit.
