Which surface is identified as a hazard for lead-based paint due to friction/impact criteria?

• A. Exterior surfaces
• B. Friction or impact surfaces
• C. Hidden surfaces behind wallpaper
• D. Ceiling surfaces

Answer: (B)

Friction/impact surfaces are those that wear down from normal use because they are repeatedly rubbed, scraped, or struck. This constant wear can cause lead-based paint to chip or generate lead dust, making these surfaces hazardous. That’s why the best answer is the one that describes surfaces subjected to regular friction or impact, such as doors, window components, and stairs. Exterior surfaces, hidden surfaces behind wallpaper, and ceilings don’t fit this specific criterion of wear from use, so they aren’t identified under the friction/impact hazard category.
