EPA LEAD INSPECTOR ACTUAL EXAM
PAPER 2026 FULL QUESTIONS WITH
CORRECT ANSWERS GRADED A+
⩥ Multi-family housing is defined as. . .
Answer: as any group of units that are similar in construction from unit
to unit with:
1. 21 or more units if any were built before 1960 or are of unknown
2. 10 or more units if they were all built from 1960 to 1977!
⩥ What are the benefits of random sampling?
Answer: 1. reducing the time and cost associated with testing
2. making it possible to reach rational decisions for large complexes
without testing every single unit.
⩥ When conducting a lead-based paint inspection, regardless of multi-
family/single-family housing, what 7 steps should be followed?
Answer: 1. List all painted testing combinations by room equivalent,
icnluding those that are stained, shellacked, varnished, coated, or painted
and covered with wall paper.
2. select testing combinations
3. Perform xrf testing
,4. Collect and analyze paint-chip samples for testing combinations that
cannot be tested with XRF or that inconclusive XRF results; if
applicable;
5. Classify XRF and paint chip results
6. Evaluate the work and results to ensure quality of the paint inspection.
7. Document the findings in a report
⩥ What is a testing combination made up of?
Answer: 1. room equivalent
2. component
3. substrate
⩥ For single-family housing, the HUD Guidelines recommend XRF
testing on at least. . .
Answer: 1. One location PER testing combination, except interior and
exterior walls
2. four readings, one on each wall
⩥ What should be done for testing exterior walls?
Answer: 1. select at least four sides;
2. average the readings (rounding the result as described above) to
obtain a result for any remaining side.
,⩥ What are good paint conditions for an area to be selected for XRF
testing?
Answer: Areas where the paint appears to be thickest should be selected.
At each test location include all layers of paint and lay the XRF probe
faceplate flat against the surface.
⩥ What areas should not be used and should be avoided during XRF
testing?
Answer: Locations where the paint has worn away or been scraped off
should not be selected. As well as areas over pipes, electrical surfaces,
nails, and other possible interferences should be avoided if possible as
these materials may contain lead.
⩥ What does the abbreviation A2LA stand for?
Answer: American Association for Laboratory Accrediation
⩥ Define Abatement
Answer: A measure or set of measures designed to permanently
eliminate lead-based paint hazards or lead-based paint. Abatement
strategies include the removal of lead-based paint, enclosure,
encapsulation, replacement of building components coated with lead-
based paint, removal of lead-contaminated dust, and removal of lead-
contaminated soil or overlaying of soil with a durable covering such as
asphalt (grass and sod are considered interim control measures).
, All of these strategies require preparation; cleanup; waste disposal;
post-abatement clearance testing; recordkeeping; and, if applicable,
monitoring.
⩥ What is the importance of accreditation?
Answer: a formal recognition that an organization, such as a laboratory,
is competent to carry out specific tasks or types of tests
⩥ Define Accuracy
Answer: the degree of agreement between an observed value and an
accepted reference value (a "true" value); a data quality indicator.
Accuracy includes a combination of random errors (precision) and
systematic errors (bias) due to sampling and analysis.
⩥ Define Action Level
Answer: the level at which an employer must begin certain compliance
activities outlined in the OSHA lead standard. The action level,
regardless of respirator use, for the lead in construction standard is an
airborne concentration of 30 µg/m^3 calculated as an 8-hour TWA.
⩥ How would you define an acute effect of lead exposure?
Answer: severe or immediate reaction, usually to a single large
exposure.
⩥ How would you define adequate quality control?
