What is considered an impact surface in lead hazard contexts?

• A. An interior or exterior surface subject to damage from repeated impacts (parts of door frames).
• B. A glass window exposed to sunlight.
• C. A wall that never receives contact.
• D. A ceiling not touched by objects.

Answer: (A)

In lead hazard contexts, an impact surface is a painted surface that is likely to be damaged by regular contact or banging, so it can chip and generate lead-containing dust or chips. Door frames are a prime example because they endure repeated contact from opening, closing, bumps, and scraping, which wears away the paint over time. The other options don’t fit because a glass window isn’t a painted surface prone to paint chipping from impact, and surfaces that rarely or never receive contact—like a wall that never gets touched or a ceiling not struck by objects—aren’t likely to release lead dust from paint due to impact.
