EPA Lead Risk Assessor Exam Study Guide Guaranteed Success
### Guidelines and Assessment
1. Which federal document outlines guidelines for inspections and lead management activities?
- The HUD Guidelines serve as a comprehensive federal document that provides overarching protocols
for conducting inspections, risk assessments, and abatement processes related to lead.
2. What is the primary purpose of a lead risk assessment?
- The purpose of a lead risk assessment is to identify potential lead-based paint (LBP) hazards that
could pose a risk to individuals, particularly children.
3. What does the acronym EBL stand for in the context of lead exposure?
- EBL refers to Elevated Blood Level, indicating a concerning amount of lead in a child's bloodstream.
### Exposure and Health Considerations
4. How do children primarily ingest lead?
- Lead primarily enters children's bodies through the ingestion of lead dust found in their environment.
5. Would a child with blood lead levels of 17 µg/dL, 9 µg/dL, and 16 µg/dL be diagnosed with lead
poisoning?
- No, because the elevated blood levels of 17 µg/dL and 16 µg/dL are not consecutive; the 9 µg/dL
level interrupts the sequence.
### Inspection and Sampling Methods
6. Which inspection type is more beneficial for contractors involved in renovation projects, lead
inspection or risk assessment?
, - Lead inspections tend to be more useful for renovation contractors as they reveal specific lead
hazards that may need attention during renovation work.
7. What sampling methods do Risk Assessors use to detect lead hazards?
- Risk Assessors typically employ six sampling methods to identify lead hazards, including:
- Visual inspection
- Dust sampling
- Soil testing
- Paint chip analysis
- XRF analysis (X-ray fluorescence)
- Water testing
8. What is the OSHA Action Level for lead exposure?
- The OSHA Action Level for lead is set at 30 µg/m³.
9. Is water sampling mandatory as part of a Risk Assessment?
- Water sampling is considered optional during a Risk Assessment.
### Lead Hazards and Clearance Levels
10. What are the six types of lead-based paint hazards recognized by the EPA?
- The six identified lead-based paint hazards are:
- Dust
- Friction surfaces
- Impact surfaces
- Chewable surfaces
- Deteriorated paint
- Soil
, 11. What are the EPA's soil lead hazard levels?
- For general yard areas, the EPA considers a soil lead hazard to be 1,200 ppm (parts per million).
### Analytical Techniques and Safety Standards
12. What is XRF analysis, and what does it typically measure?
- XRF (X-ray fluorescence) analysis is a prevalent method for identifying lead content in various
materials. It is most commonly applied to determine lead presence rather than assess lead hazards.
13. Where can operational data for an XRF be found?
- Operational data and specifications for an XRF can be found in the Performance Characteristic Sheet
(PCS) that comes with the equipment.
14. How many dust samples are generally collected for a Risk Assessment?
- Typically, around 13 dust samples are taken during a Risk Assessment process.
### Lead Abatement Methods
15. What are the primary methods of lead abatement?
- The main techniques for lead abatement include:
- Removal of lead-based materials
- Enclosure of lead hazards
- Encapsulation of lead surfaces
16. How often is an XRF calibrated?
- Calibration of an XRF should occur at the beginning, end, every four hours, and every time the device
is powered down.
17. What is the lead content per XRF considered as lead-based paint (LBP)?
