,This study document brings together 110 carefully worded exam questions drawn from EPA Lead
Inspector Actual Exam - Environmental Protection Agency (EPA) / TSCA Section 402 - 2026/2027
Academic Year - Verified Questions and Answers, with the strongest emphasis placed on Analyze
and apply EPA/HUD lead regulations to field inspection scenarios, Evaluate lead hazard
assessment techniques and interpret XRF and laboratory data, Synthesize regulatory, technical
and and ethical considerations in lead hazard management. Every item follows the wording style
and level of reasoning you meet in the real paper, and each one is paired with a clear rationale so
the correct choice is never a guess. Work through the set at your own pace, mark the questions
that slow you down, then come back to them until the reasoning feels automatic. Learners who
revise this way walk into the exam room recognising the pattern behind the questions instead of
meeting them for the first time. Keep going - steady, honest practice is what turns a difficult paper
into a comfortable pass.
Q1 ANALYZE AND APPLY EPA/HUD LEAD REGULATIONS TO FIELD INSPECTION SCENARIOS
A lead inspector is evaluating a pre-1978 dwelling for a potential lead-based paint
hazard. Which combination of factors most accurately defines a 'lead-based paint
hazard' under EPA regulations (40 CFR 745.63)?
A. Any paint with a lead content 1.0 mg/cm² and any deteriorated paint in a dwelling.
B. Deteriorated lead-based paint, lead-contaminated dust, lead-contaminated soil, or
lead-contaminated drinking water that would result in adverse human health effects. CORRECT
C. Any surface coated with lead-based paint that is accessible to children under six years of age.
D. Paint that contains lead in excess of 0.5% by weight and is on an impact surface.
RATIONALE: Under 40 CFR 745.63, a lead-based paint hazard is defined as any condition that
causes exposure to lead from lead-contaminated dust, soil, or deteriorated lead-based paint that
would result in adverse human health effects. Option A is too broad, C is incomplete, and D
refers to the definition of lead-based paint, not a hazard.

,Q2 ANALYZE AND APPLY EPA/HUD LEAD REGULATIONS TO FIELD INSPECTION SCENARIOS
During an XRF inspection, an inspector obtains a reading of 1.2 mg/cm² on a
painted surface. According to EPA's XRF performance characteristic sheets (PCS),
what is the most appropriate classification?
A. Inconclusive, because the reading is within the instrument's margin of error.
B. Positive for lead-based paint, because 1.2 mg/cm² exceeds the 1.0 mg/cm² threshold.
CORRECT
C. Negative, because the reading is below the HUD action level of 1.5 mg/cm².
D. Requires laboratory confirmation, because XRF readings above 1.0 mg/cm² are not definitive.
RATIONALE: EPA's PCS for XRF instruments specify that readings at or above 1.0 mg/cm² are
positive for lead-based paint. A reading of 1.2 mg/cm² is above the threshold, so it is positive.
The margin of error and laboratory confirmation apply to readings in the inconclusive zone, which
is typically below 1.0 mg/cm² for most instruments.
Q3 ANALYZE AND APPLY EPA/HUD LEAD REGULATIONS TO FIELD INSPECTION SCENARIOS
A lead inspector is preparing a risk assessment for a property with a history of
lead paint. Which of the following procedures is NOT required for a complete risk
assessment under HUD guidelines?
A. Collecting dust wipe samples from floors and window sills in rooms where children are likely
to play.
B. Collecting soil samples from bare areas around the building foundation and play areas.
C. Visually inspecting all painted surfaces for deterioration and friction/wear.
D. Collecting paint chip samples from every painted surface in the dwelling. CORRECT
RATIONALE: A risk assessment under HUD guidelines requires visual inspection, dust sampling,
and soil sampling, but not paint chip sampling from every surface. Paint chip sampling is used to
confirm lead content when XRF is inconclusive or for specific surfaces, not as a blanket
procedure. Therefore, option D is not required.

, Q4 ANALYZE AND APPLY EPA/HUD LEAD REGULATIONS TO FIELD INSPECTION SCENARIOS
An inspector is using an XRF analyzer that has a source of radiation. Which of the
following safety practices is most critical to comply with state and federal
regulations?
A. Wearing a lead apron at all times while operating the device.
B. Maintaining a radiation safety program and carrying a dosimeter badge. CORRECT
C. Ensuring that the device is calibrated annually by the manufacturer.
D. Keeping a log of all readings for at least 3 years.
RATIONALE: XRF analyzers using radioactive sources require a radiation safety program,
including personnel monitoring (dosimeter badges) and compliance with state radiation
regulations. A lead apron is not required for low-energy XRF devices. Annual calibration and
reading logs are important but not the most critical safety practice. Option B directly addresses
regulatory safety requirements.
Q5 ANALYZE AND APPLY EPA/HUD LEAD REGULATIONS TO FIELD INSPECTION SCENARIOS
Under the EPA's Renovation, Repair, and Painting (RRP) Rule, which of the
following situations requires a certified renovator to perform post-construction
dust wipe testing?
A. A renovation that disturbs more than 6 square feet of lead-based paint in a pre-1978 rental
property.
B. A renovation that disturbs less than 20 square feet of painted surface in a pre-1978
owner-occupied home.
C. A renovation that involves window replacement in a pre-1978 child-occupied facility.
CORRECT
D. Any renovation project that uses a HEPA vacuum for cleanup.
RATIONALE: The RRP Rule requires dust wipe testing after renovations in child-occupied
facilities, such as schools or daycare centers, when the renovation disturbs lead-based paint.
Window replacement is a trigger for dust testing in child-occupied facilities. Option A is incorrect
because dust testing is not required for rental properties under RRP (unless specified by state or
contract). Option B is exempt because owner-occupied homes are not covered by RRP. Option D
is not a trigger.
