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

What are accessible surfaces in lead hazard assessments?

1. Similar to door stops in design

2. Interior or exterior surfaces that young children can mouth or chew

3. Surfaces that are permanently sealed

4. Any surface in a residential building

The correct answer is: Interior or exterior surfaces that young children can mouth or chew

Accessible surfaces in lead hazard assessments specifically refer to interior or exterior surfaces that young children can mouth or chew. This definition is crucial because children are particularly vulnerable to lead exposure, which can occur when they come into contact with lead-based paint and then ingest lead dust or chips. The term "accessible" indicates that these surfaces are within reach of children, making it necessary to evaluate them for potential lead hazards. The focus on surfaces that children might chew or mouth emphasizes the need for thorough inspections in areas where children typically play or spend time. Recognizing these surfaces allows assessors to prioritize remediation efforts in places most likely to pose a risk to young children, thus protecting public health and ensuring compliance with safety regulations. In contrast, other options do not accurately represent the unique concern surrounding lead exposure in children. For example, surfaces that are permanently sealed are less likely to pose a risk of lead exposure since they contain the lead and prevent direct contact. Similarly, while any surface in a residential building may eventually be of concern, not all surfaces are accessible to young children, which is the critical factor in determining lead hazard assessments.
