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

What is one of the four expectable methods for paint removal?

1. Encapsulation

2. Friction and impact reduction

3. Air scraping

4. Water blasting

The correct answer is: Friction and impact reduction

The expectation for effective paint removal methods typically includes techniques that are recognized for their safety and efficiency, particularly in relation to lead-based paints. Among the traditional methods, friction and impact reduction stands out as a viable approach. This method involves gently scuffing or scraping the surface to persuade the paint to release from the substrate, which can be a less invasive option compared to others that may generate dust or lead exposure risks. Friction and impact reduction is generally seen as a safer alternative because it minimizes the release of lead particulates into the environment, making it a suitable choice for scenarios where reducing dust creation is paramount. In addition, when done properly, this method can effectively preserve the underlying materials being treated, which can often be a concern in older structures containing lead paint. While there are other methods available for paint removal, they might involve more aggressive techniques that can lead to health hazards if not managed correctly. Understanding the nuanced benefits of friction and impact reduction allows risk assessors to make safer decisions in environments where lead-based paint is present.
