Environmental Protection Agency (EPA) Model Lead Based Paint Risk Assessor Practice Test

Which of the following is NOT a component of stairs related to lead-based paint risks?

1. Balustrade

2. Newel post

3. Carpet padding

4. Stair riser

The correct answer is: Carpet padding

Carpet padding is not typically considered a component of stairs that contributes directly to lead-based paint risks. When assessing lead hazards, emphasis is placed on various structural elements of the stairs, such as the balustrade, newel post, and stair riser, as these components can harbor lead-based paint, particularly in older homes where lead paint was commonly used prior to regulations established in the late 1970s. The balustrade and newel post are parts of the stair's framework and are likely to have been painted with lead-based paints if the building predates the regulations. Stair risers are also crucial components where lead paint could exist, especially on surfaces that might be frequently touched or disturbed. Carpet padding, while it may be located under carpets on the steps, does not have a direct connection to painted surfaces or lead dust. It's primarily a comfort layer and not a structural or decorative component that would typically contain lead paint. Consequently, when evaluating lead exposure risks associated with stair components, carpet padding is excluded from consideration.
