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

In dwellings built post-1978, what does a risk assessor not need to check for?

1. Paint deterioration

2. Presence of lead-based paint

3. Unpainted window tracks

4. Evidence of mouthing or chewing on the window sill

The correct answer is: Evidence of mouthing or chewing on the window sill

In dwellings constructed after 1978, a risk assessor is not required to check for evidence of mouthing or chewing on the window sill primarily because the use of lead-based paint was banned in residential properties for children. Thus, the likelihood of lead exposure from paint in homes built after this cutoff is significantly reduced. The presence of lead-based paint and its deterioration is critical to assess in homes built before 1978, as that is when the ban took effect, meaning older homes can still pose a risk. Similarly, checking for unpainted window tracks would help identify areas where lead dust could accumulate, which might still be a concern even if the paint itself is not lead-based. Therefore, focusing on evidence of mouthing or chewing on the window sill in newer homes is unnecessary in the context of lead exposure risk assessments.
