Which surfaces are considered friction surfaces?

Which surfaces are considered friction surfaces?

• A. An interior or exterior surface subject to abrasion or friction (certain window, floor, and stair surfaces)
• B. Ceilings and walls that do not experience wear
• C. Exterior walls
• D. Surfaces behind wallpaper

Answer: (A)

Friction surfaces are surfaces that experience abrasion or friction during normal use. In homes with lead paint, these areas are where paint is most likely to wear away and create lead-containing dust because they’re repeatedly rubbed, walked on, or moved against. That includes interior or exterior surfaces that are subject to abrasion, such as window components, floors, and stairs. Ceilings and walls that don’t experience wear, exterior walls that aren’t rubbing, or surfaces behind wallpaper aren’t typically subject to that kind of wear, so they aren’t friction surfaces. Therefore, the best description is surfaces that are subject to abrasion or friction, like certain window, floor, and stair surfaces.
