EPA LEAD RISK ASSESSOR EXAM STUDY GUIDE/EPA LEAD RISK ASSESSOR EXAM
STUDY GUIDE LATEST 2025/2026;QUESTIONS AND ANSWERS FULLY SOLVED 100%.
Question 1
Which Federal document serves as the primary guideline for performing lead-based paint
inspections, risk assessments, and abatement activities?
A) OSHA 1926.62
B) The Toxic Substances Control Act (TSCA)
C) The HUD Guidelines
D) The Clean Air Act
E) The Resource Conservation and Recovery Act (RCRA)
Correct Answer: C) The HUD Guidelines
Rationale: The HUD "Guidelines for the Evaluation and Control of Lead-Based Paint
Hazards in Housing" is the comprehensive technical manual used by professionals to
conduct inspections, risk assessments, and clearance following abatement.
Question 2
What medical treatment is typically used for a child who has been diagnosed with severe lead
poisoning?
A) Physical therapy
B) Chelation therapy
C) Antibiotic therapy
D) Cognitive behavioral therapy
E) Intravenous rehydration only
Correct Answer: B) chelation therapy
Rationale: Chelation therapy involves the administration of a medication that binds to lead
in the bloodstream and tissues, allowing it to be excreted by the kidneys. This is typically
required when blood lead levels reach 45 µg/dL or higher.
Question 3
What is the primary purpose of conducting a "Lead Risk Assessment" as opposed to a "Lead
Inspection"?
A) To identify every location of lead-based paint in the building
B) To provide a cost estimate for total demolition
C) To identify lead-based paint hazards (dust, soil, and deteriorating paint)
D) To test the structural integrity of the foundation
E) To determine the market value of the property
Correct Answer: C) Identify LBP hazards
Rationale: While an inspection identifies where lead-based paint exists, a risk assessment
identifies where lead currently poses a health risk (hazards) to occupants, specifically
through dust, soil, or deteriorating surfaces.
Question 4
In the context of lead poisoning, what does the acronym "EBL" stand for?
, 2
A) Estimated Baseline Level
B) Environmental Biological Limit
C) Elevated Blood Level
D) Exposed Body Limit
E) Essential Blood Lead
Correct Answer: C) Elevated Blood Level
Rationale: EBL is the term used to describe a concentration of lead in the blood that exceeds
the current threshold for clinical concern in children or adults.
Question 5
What is the most common route through which lead primarily enters a child's body?
A) Absorption through the skin (dermal)
B) Inhalation of tobacco smoke
C) Ingestion of lead-contaminated dust or paint chips
D) Ingestion of unwashed fruit
E) Exposure to UV radiation
Correct Answer: C) Ingestion of lead dust
Rationale: Children are most commonly poisoned through "hand-to-mouth" activity, where
they ingest lead-contaminated dust that has settled on floors, toys, and window sills.
Question 6
A child has three blood lead tests in the following order: 17 µg/dL, 9 µg/dL, and 16 µg/dL.
According to standard definitions, is this child considered to have "consecutive" elevated blood
levels?
A) Yes, all levels are above 5 µg/dL.
B) No, because the second test was lower and they were not in sequence.
C) Yes, because the first and last were high.
D) No, because all three must be above 20 µg/dL.
E) Yes, because the average is over 15 µg/dL.
Correct Answer: B) No, the elevated blood levels of 17ug/dL and 16ug/dL were not
consecutive
Rationale: A definition of lead poisoning often requires two consecutive readings in a
specific range (e.g., 15-19 µg/dL taken at least 3 months apart). The drop to 9 µg/dL breaks
the consecutive sequence.
Question 7
Which service is more useful for a renovation contractor seeking to comply with the RRP
(Renovation, Repair, and Painting) rule?
A) The Lead Risk Assessment
B) The Lead Inspection
C) A water quality test
, 3
D) A soil analysis only
E) A building permit
Correct Answer: B) Lead Inspection
Rationale: Renovators need to know if and where lead-based paint exists on any component
they are disturbing. A lead inspection provides a component-by-component report, which is
more useful for determining work practices than a risk assessment.
Question 8
Which of the following represents the six sampling methods used by Risk Assessors to identify
lead hazards?
A) Visual, Dust, Soil, Paint Chip, XRF, and Water
B) Air, Dust, Blood, Urine, Hair, and Soil
C) Visual, Tape, Vacuum, Bulk, Air, and Wipe
D) XRF, Ultrasound, Infrared, Visual, Soil, and Water
E) Paint Chip, Magnetic, Chemical, Visual, Soil, and Dust
Correct Answer: A) Visual, Dust, Soil, Paint Chip, XRF, Water
Rationale: Risk assessors combine physical sampling (dust, soil, paint chips, water) with on-
site analysis (XRF) and visual observation of the dwelling's condition to provide a complete
hazard profile.
Question 9
Under what condition may a certified Risk Assessor conduct an assessment on a property that is
scheduled to be abated by the firm they work for?
A) No conditions; it is a total conflict of interest.
B) If they offer the client a 50% discount.
C) If they notify the client in writing of the potential conflict.
D) Only if the building is a Child Occupied Facility.
E) If they have a Master's degree in Toxicology.
Correct Answer: C) Notify the client in writing
Rationale: To maintain transparency, federal law allows risk assessors to work on projects
associated with their firm only if the relationship is disclosed to the client in writing.
Question 10
What is the OSHA "Action Level" for lead exposure in the workplace?
A) 10 µg/m³
B) 30 µg/m³
C) 50 µg/m³
D) 100 µg/m³
E) 400 µg/m³
Correct Answer: B) 30 ug/m3
