EPA Lead Inspector Verified Answers
1. What constitutes lead-based paint (LBP)?
- Answer: Lead-based paint is defined as any coating that contains lead at a concentration of 1 mg/cm²
or 0.5% by weight.
2. What is the significance of Title X legislation?
- Answer: Title X, formally known as the Residential Lead-Based Paint Hazard Reduction Act of 1992,
shifted the focus of federal regulations from addressing existing lead-based paint hazards to the
prevention of new hazards. It establishes regulations for the training and certification of lead
professionals, although it does not mandate lead-based paint inspections, risk assessments, or
abatement in designated housing or child-occupied facilities. This act was designed to protect families
from exposure to lead from sources such as paint, dust, and soil, primarily in homes that already contain
lead-based paint.
3. Why are children particularly vulnerable to elevated blood lead levels (EBLL)?
- Answer: Children are more susceptible to EBLL for three primary reasons: their developmental
stages, behavioral habits, and their smaller body stature.
4. What is involved in a lead-based paint inspection?
- Answer: A lead-based paint inspection consists of a systematic surface-to-surface assessment
conducted to identify whether lead-based paint is present, in accordance with Title X.
5. How is deteriorated paint defined?
- Answer: Deteriorated paint is characterized by conditions such as chipping, chalking, and flaking.
6. What is considered an accessible surface in terms of lead exposure?
- Answer: Accessible surfaces, often referred to as "chewable" surfaces, include areas like window sills
where young children may come into contact with lead.
7. What does a friction surface refer to?
, - Answer: A friction surface refers to interior or exterior areas that experience abrasion or friction,
such as windows, floors, and stair surfaces.
8. Define an impact surface.
- Answer: An impact surface is any interior or exterior surface that is prone to damage due to repeated
sudden forces, such as door frames.
9. What does abatement entail?
- Answer: Abatement encompasses any measures designed to permanently eliminate lead-based
paint, including the removal of lead paint and dust, the permanent enclosure or encapsulation of lead-
based paint, and the replacement of affected painted surfaces, as well as soil removal.
10. What is classified as a child-occupied facility?
- Answer: A child-occupied facility is defined as any building or part of a building constructed before
1978 that is frequented by the same child under six years old at least twice per week and for three hours
at a time, or in cases where visits total six hours in a week.
11. What does clearance level signify in lead remediation?
- Answer: Clearance levels refer to the maximum permissible lead concentrations in dust on surfaces
following the completion of abatement activities.
12. What are the EPA and state clearance levels for dust on various surfaces?
- Answer:
- Interior floors: 40 micrograms/ft²
- Interior window sills: 250 micrograms/ft²
- Window troughs: 400 micrograms/ft²
13. What are the EPA and state clearance levels for soil samples?
- Answer:
- Playground and child areas: 400 micrograms/g
- Other yard areas: 1200 micrograms/g
