Lead-based paint hazard includes exposures from which surfaces when contaminated and deteriorated?

Lead-based paint hazard includes exposures from which surfaces when contaminated and deteriorated?

• A. Only exterior surfaces
• B. Only interior surfaces
• C. Accessible surfaces, friction surfaces, or impact surfaces
• D. Only surfaces within 1 foot of the floor

Answer: (C)

Lead exposure from deteriorated paint comes from surfaces people interact with and that generate lead dust or chips through normal use. Accessible surfaces are those you can reach and touch, so any damaged paint on walls, trim, windows, or countertops that people frequently handle can release lead-contaminated dust. Friction surfaces are places where surfaces rub against each other during use—think window sashes and tracks, door frames, and other areas where wear creates dust as the paint wears away. Impact surfaces are surfaces that are repeatedly bumped or struck, such as stairs, stair treads, and railings, where chipping can occur from daily activity. Together, these surface types cover the situations most likely to produce lead exposure when paint is contaminated and deteriorated. That’s why this choice is correct: it reflects the surfaces most capable of releasing lead-containing dust or chips through normal use, rather than limiting exposure to interior only, exterior only, or a fixed distance from the floor.
