Free LBPI Practice Questions

10 free, exam-style EPA Lead-Based Paint Inspector (LBPI) practice questions with answers and explanations. No signup required. Work through them below, then take the full free LBPI practice test to study every exam domain.

These 10 free LBPI questions are organized by exam domain, so you can see how each part of the EPA Lead-Based Paint Inspector blueprint is tested. Reveal the answer and explanation under each question.

Domain 1: Role and Responsibilities of an Inspector

Question 1

Lead-based paint is defined under federal regulations as paint or surface coating containing lead at or above:

  1. 0.5 mg/cm² or 1.0% by weight
  2. 1.0 mg/cm² or 5.0% by weight
  3. 1.0 mg/cm² or 0.5% by weight
  4. 5.0 µg/ft² or 40 ppm
Show answer & explanation

Correct answer: C - 1.0 mg/cm² or 0.5% by weight

Question 2

The CDC uses a blood lead reference value (BLRV) to identify children with blood lead levels higher than most children. As of the most recent update, that value is:

  1. 10 µg/dL
  2. 5 µg/dL
  3. 0 µg/dL, because no level of lead in blood is considered safe
  4. 3.5 µg/dL
Show answer & explanation

Correct answer: D - 3.5 µg/dL

Question 3

Under the federal Lead Disclosure Rule (TSCA §1018 / Title X), when target housing is sold, the seller must give the purchaser an opportunity to conduct a lead-based paint inspection or risk assessment lasting:

  1. 3 days
  2. 10 days (or another period the buyer and seller agree to)
  3. 30 days
  4. No inspection period is required; only known information must be disclosed
Show answer & explanation

Correct answer: B - 10 days (or another period the buyer and seller agree to)

Domain 2: Background Information on Lead and Its Adverse Health Effects

Question 4

Following a lead-based paint abatement, dust-wipe clearance samples are collected from the work area. Under EPA's current standards (full compliance required January 2026), the post-abatement dust-lead action level for floors is:

  1. 5 µg/ft²
  2. 10 µg/ft²
  3. 40 µg/ft²
  4. 100 µg/ft²
Show answer & explanation

Correct answer: A - 5 µg/ft²

Question 5

During an inspection, an XRF analyzer returns a reading that falls within the instrument's inconclusive range as defined on its Performance Characteristic Sheet (PCS). The inspector should:

  1. Record the component as positive for lead-based paint
  2. Record the component as negative for lead-based paint
  3. Collect a paint-chip sample for laboratory confirmation
  4. Continue taking XRF readings until a conclusive value appears
Show answer & explanation

Correct answer: C - Collect a paint-chip sample for laboratory confirmation

Question 6

A certified lead inspector who is NOT certified as a risk assessor is hired for a pre-1978 home. Which task falls OUTSIDE the inspector's certified scope of practice?

  1. Determining the presence and exact location of lead-based paint
  2. Collecting dust-wipe samples for a post-abatement clearance examination
  3. Testing painted surfaces using XRF and laboratory paint-chip analysis
  4. Conducting a risk assessment and recommending hazard control options
Show answer & explanation

Correct answer: D - Conducting a risk assessment and recommending hazard control options

Question 7

Bare soil is sampled in a child's play area at a residential property. Under the TSCA Section 403 soil-lead hazard standard, a hazard exists when the lead concentration in the play area equals or exceeds:

  1. 200 ppm
  2. 400 ppm
  3. 1,200 ppm
  4. 5,000 ppm
Show answer & explanation

Correct answer: B - 400 ppm

Question 8

After a lead abatement project, multiple dust-wipe samples are collected for clearance. For the abated area to pass clearance, the results must show that:

  1. Every individual sample is below the applicable action level
  2. The arithmetic mean of all samples is below the applicable action level
  3. At least 90% of the samples are below the applicable action level
  4. The floor samples are below the action level, regardless of window results
Show answer & explanation

Correct answer: A - Every individual sample is below the applicable action level

Question 9

Several methods may be used to abate lead-based paint, but certain practices are prohibited because they generate excessive lead dust or fumes. Which of the following is a PROHIBITED abatement method?

  1. Open-flame burning or torching of painted surfaces
  2. Replacing the painted component
  3. Enclosing the surface with a durable, mechanically fastened barrier
  4. Wet scraping followed by HEPA vacuuming
Show answer & explanation

Correct answer: A - Open-flame burning or torching of painted surfaces

Domain 3: Background Information on Federal, State, and Local Regulations and Guidance

Question 10

Under OSHA's Lead in Construction standard (29 CFR 1926.62), the permissible exposure limit (PEL) for airborne lead, averaged over an 8-hour workday, is:

  1. 5 µg/m³
  2. 30 µg/m³
  3. 100 µg/m³
  4. 50 µg/m³
Show answer & explanation

Correct answer: D - 50 µg/m³
