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

What is a common cause of lead dust in environments?

1. Old plumbing systems

2. Renovation activities

3. Erosion of painted surfaces

4. Paint flaking away in high humidity

The correct answer is: Renovation activities

Renovation activities are a common cause of lead dust in environments, particularly in older buildings where lead-based paint may still be present. During renovations, activities such as sanding, scraping, and demolition can disturb lead-containing materials, releasing lead dust into the air and onto surfaces. This dust can then be inhaled or ingested, posing serious health risks, especially to young children and pregnant women. Understanding the impact of renovation activities is crucial, as it emphasizes the importance of proper lead-safe work practices. These practices include using protective sheeting, minimizing dust generation, and employing HEPA (High-Efficiency Particulate Air) filters to capture lead dust during the work process. By acknowledging the risks associated with renovation, property owners and contractors can take appropriate measures to mitigate lead exposure, safeguarding the health of those who live and work in these environments.
