Environmental Protection Agency (EPA) Lead Risk Assessor Practice Exam

What is the definition of a Child Occupied Facility in regard to surface area disturbance?

1. Disturbed areas over 10% surface area

2. Areas disturbed are less than 20 sq. ft. for exterior surfaces

3. Disturbance under 5 sq. ft. for any surface

4. Any unoccupied child spaces

The correct answer is: Areas disturbed are less than 20 sq. ft. for exterior surfaces

The definition of a Child Occupied Facility concerning surface area disturbance relates to the threshold for what constitutes a significant disturbance that may pose a risk of lead exposure to children. The correct answer specifies that for exterior surfaces, areas disturbed must be less than 20 square feet to still be considered within a safe threshold. This definition is rooted in regulatory guidelines designed to protect children from lead hazards commonly found in poorly maintained or older homes. By setting a limit of 20 square feet for exterior surface disturbances, the regulations aim to minimize the potential for lead dust or debris to spread into spaces where children might play or otherwise be exposed. This threshold acknowledges that larger disturbances may increase the risk of lead exposure due to the likelihood of lead particles becoming airborne or contaminating surrounding areas. In contrast, other specific disturbance guidelines indicate minor thresholds that don't incorporate the broader implications of surface area exposure as effectively. For example, a description of disturbed areas over 10% surface area doesn't directly relate to specific risk scenarios, as the percentage may vary significantly in practical application. Similarly, another option discussing disturbance under 5 square feet for any surface is too vague and does not account for the particular circumstances of child-occupied facilities. Finally, the option referencing any unoccupied child spaces disregards the
