MULTICHOICE ANSWERED EXAM QUESTIONS WITH DETAILED
RATIONALES
1. According to the EPA, a lead-based paint hazard is best defined as:
A. Any painted surface containing more than 0.06% lead
B. Any condition causing exposure to intact lead-based paint
C. Any condition causing exposure to lead from deteriorated paint, dust, or soil resulting in
adverse health effects
D. Only lead found in drinking water systems
Correct Answer: C
Rationale:
The EPA defines a lead-based paint hazard as any condition that causes exposure to lead from
deteriorated paint, contaminated dust, or soil that may result in adverse human health effects.
2. According to the CDC (2021), an elevated blood lead level (EBLL) in children is defined as:
A. ≥ 10 µg/dL
B. ≥ 7 µg/dL
C. ≥ 5 µg/dL
D. ≥ 3 µg/dL
Correct Answer: C
Rationale:
The CDC lowered the reference value to 5 µg/dL to prompt earlier public health intervention
and environmental investigation.
3. According to NIOSH, elevated blood lead levels in adult workers are defined as:
A. ≥ 10 µg/dL
B. ≥ 25 µg/dL
C. ≥ 5 µg/dL
D. ≥ 40 µg/dL
,ESTUDYR
Correct Answer: C
Rationale:
NIOSH considers blood lead levels of 5 µg/dL or higher elevated for occupational exposure,
reflecting updated health risk evidence.
4. The EPA’s Renovation, Repair, and Painting (RRP) Rule applies to:
A. All buildings regardless of age
B. Only commercial facilities
C. Pre-1978 homes, child-care facilities, and preschools where paint is disturbed
D. Only abatement projects
Correct Answer: C
Rationale:
The RRP Rule applies to renovation activities disturbing lead-based paint in pre-1978 housing
and child-occupied facilities.
5. Under the Real Estate Disclosure Rule, sellers must do all EXCEPT:
A. Provide an EPA pamphlet
B. Disclose known lead hazards
C. Allow a 10-day inspection period
D. Perform lead abatement prior to sale
Correct Answer: D
Rationale:
The law requires disclosure—not abatement—prior to sale or lease.
6. Which activity is considered lead abatement?
A. Temporary paint repair
B. Routine cleaning
C. Permanent elimination of lead-based paint hazards
D. Painting over intact surfaces
, ESTUDYR
Correct Answer: C
Rationale:
Abatement refers to permanent solutions such as removal, enclosure, or encapsulation
performed by certified professionals.
7. Which step is performed FIRST in a lead risk assessment?
A. Testing
B. Visual inspection
C. Preparation and information gathering
D. Risk analysis
Correct Answer: C
Rationale:
Preparation ensures the assessor understands building age, renovation history, and prior
reports.
8. Which method is commonly used to detect lead without damaging surfaces?
A. Paint chip sampling
B. X-ray fluorescence (XRF)
C. Soil excavation
D. Visual inspection only
Correct Answer: B
Rationale:
XRF is a non-destructive testing method widely accepted by EPA and HUD.
9. Lead-based paint is defined by the EPA as paint containing:
A. ≥ 0.06% lead
B. ≥ 0.3 mg/cm²
C. ≥ 1.0 mg/cm² or ≥ 0.5% (5,000 ppm) by weight
D. Any detectable lead
