Which surface is described as interior or exterior surfaces that are subject to abrasion or friction?

• A. Accessible surface
• B. Friction surface
• C. Impact surface
• D. HUD Guidelines

Answer: (B)

Friction surfaces describe interior or exterior surfaces that wear down from rubbing or abrasion through repeated contact. This ongoing friction causes paint to wear and can generate lead dust, which is a key concern in lead hazard evaluations. Surfaces like window sashes, door frames, stair treads, and other areas that consistently rub against other surfaces or objects are classic examples. Accessible surfaces refer to any surface a person can reach, which is about reachability rather than wear from rubbing. Impact surfaces are those likely to be damaged by a strong impact, not ongoing friction. HUD Guidelines is the document that defines these categories, not a surface type itself. So the term that matches “interior or exterior surfaces that are subject to abrasion or friction” is friction surface.
