1. Under California regulations, which of the following is the definition of a "lead hazard"?
A) Any detectable amount of lead in paint, dust, or soil
B) Deteriorated lead-based paint, lead-contaminated dust, lead-contaminated soil, or
disturbing lead-based paint without containment
C) Lead-based paint in any residential building constructed before 1978
D) Any lead-containing material that exceeds 0.5% by weight
Correct Answer: B
California Code of Regulations, Title 17, Section 35037 defines a "lead hazard" as deteriorated
lead-based paint, lead-contaminated dust, lead-contaminated soil, disturbing lead-based
paint without containment, or any other nuisance that may result in persistent and
quantifiable lead exposure. Options A and C are too broad, and option D refers to the federal
definition of lead-based paint, not the broader definition of a lead hazard.
2. A certified lead inspector/assessor in California is conducting a lead hazard evaluation in a
residential building. According to Title 17, CCR, which of the following is required for the
evaluation to be valid?
A) The evaluation must be conducted by a certified lead inspector/assessor
B) The evaluation must be conducted in the presence of the property owner
C) The evaluation must include testing of all painted surfaces in the building
D) The evaluation must be completed within 24 hours of the initial site visit
Correct Answer: A
Title 17, CCR Section 36000 requires that lead hazard evaluations for public and residential
buildings be conducted only by a certified lead inspector/assessor. The presence of the
,property owner (B) is not mandatory, testing all surfaces (C) is not always required, and there
is no 24-hour completion requirement (D).
3. A child has been diagnosed with a blood lead level (BLL) of 12 µg/dL. According to
California Health and Safety Code, how does this affect the determination of a lead hazard?
A) It has no effect on lead hazard determination
B) It automatically triggers an abatement order for the entire property
C) It may cause an area smaller than the standard threshold to be considered a lead hazard
D) It requires the property to be condemned
Correct Answer: C
California Health and Safety Code Section 17920.10 specifies that disturbing lead-based paint
without containment and deteriorated lead-based paint shall be considered lead hazards if an
area smaller than specified thresholds is associated with a person with a blood lead level
equal to or greater than 10 µg/dL. This recognizes that children with elevated BLLs are more
vulnerable and require a lower threshold for hazard determination.
4. What is the atomic symbol for lead, and what is the origin of its Latin name?
A) Ld; "leadum" meaning "heavy metal"
B) Pb; "plumbum" meaning "liquid silver"
C) Le; "leaden" meaning "gray"
D) Pl; "plumbago" meaning "graphite"
Correct Answer: B
The atomic symbol for lead is Pb, derived from the Latin word "plumbum," which means
"liquid silver." This historical name reflects the metal's appearance and its use in ancient
plumbing. Options A, C, and D are incorrect symbols or origins.
5. A lead inspector is preparing to collect dust wipe samples in a residential unit. According to
HUD guidelines, which of the following is the correct procedure for dust sampling?
A) Collect samples from a 1 ft × 1 ft area using a single wipe
B) Collect samples from a 1 ft × 1 ft area using two wipes (one dry, one wet)
C) Collect samples from a 2 ft × 2 ft area using a single wipe
D) Collect samples from a 2 ft × 2 ft area using three wipes
,Correct Answer: B
HUD guidelines specify that dust wipe samples should be collected from a 1 ft × 1 ft area using
two wipes—one dry wipe followed by one wet wipe—to maximize recovery of lead-
contaminated dust. This standardized procedure ensures consistency and comparability of
results across inspections.
6. According to California regulations, how long does an individual have to apply for lead
certification after completing their CDPH-accredited training?
A) 6 months
B) 1 year
C) 2 years
D) 3 years
Correct Answer: D
The California Department of Public Health requires that individuals apply for lead
certification within 3 years of completing their CDPH-accredited training. If the application is
not submitted within this timeframe, the individual must retake the training course.
7. Which of the following federal agencies is responsible for establishing the national
standards for lead-based paint activities, including inspector and risk assessor certification?
A) OSHA (Occupational Safety and Health Administration)
B) EPA (Environmental Protection Agency)
C) HUD (Department of Housing and Urban Development)
D) CDC (Centers for Disease Control and Prevention)
Correct Answer: B
The Environmental Protection Agency (EPA) establishes the national standards for lead-based
paint activities under the Toxic Substances Control Act (TSCA), including the certification
requirements for inspectors and risk assessors. HUD focuses on housing-specific guidelines,
OSHA addresses workplace safety, and CDC provides health-related guidance.
8. A certified lead risk assessor is evaluating a property where a child has been diagnosed
with lead poisoning. Which of the following is the most important source of lead exposure to
investigate?
, A) Lead-contaminated soil in the yard
B) Lead-based paint in good condition on the walls
C) Lead-contaminated dust from deteriorated paint
D) Lead in the household drinking water
Correct Answer: C
Lead-contaminated dust from deteriorated paint is the most common and significant source of
lead exposure for children, as they ingest dust through normal hand-to-mouth
activities. While soil (A) and water (D) can be sources, dust from deteriorated paint is the
primary pathway in most childhood lead poisoning cases.
9. Under California law, which of the following persons is required to be certified to perform
lead hazard evaluations for compensation?
A) Any person who performs lead hazard evaluations, including lead inspections, risk
assessments, or clearance inspections
B) Only persons performing abatement work
C) Only persons working on public buildings
D) Only persons who use XRF analyzers
Correct Answer: A
California Health and Safety Code Section 105254 requires that persons who receive pay for
doing lead hazard evaluations—including lead inspections, risk assessments, or clearance
inspections—in residential or public buildings must be certified. This requirement extends to
all compensated lead hazard evaluation activities, not just abatement work (B) or specific
techniques (D).
10. What is the federal action level for lead in dust on floors in target housing, as established
by EPA?
A) 10 µg/ft²
B) 20 µg/ft²
C) 40 µg/ft²
D) 100 µg/ft²
Correct Answer: A
