Environmental Protection Agency (EPA) Lead Risk Assessor Practice Exam

Lead-safe work practice measures aim to do which of the following?

1. Minimize dust generation

2. Maximize dust generation

3. Alter building structure

4. Increase exposure to lead

The correct answer is: Minimize dust generation

Lead-safe work practice measures are designed to minimize dust generation because dust is a primary route through which lead particles become airborne and hazardous. By controlling and reducing dust, these practices help prevent lead contamination in the environment, particularly during renovation, repair, and painting activities that may disturb lead-based paint. The goal of these work practices is to create a safe working environment and reduce the risk of lead exposure to both workers and residents, especially in older housing where lead paint may still be present. Techniques such as containing work areas, using vacuum systems, and wet methods can significantly lower the amount of dust produced. The other choices do not align with the objectives of lead-safe practices. Maximizing dust generation, altering the structure without consideration of safety measures, or increasing exposure to lead would all contribute to a higher risk of lead poisoning, contrary to the purpose of these safety measures. Thus, minimizing dust generation is fundamental in efforts to protect health and ensure compliance with environmental safety standards.
