ASBESTOS INSPECTOR CERTIFICATION: COMPLETE
PRACTICE EXAM WITH ANSWERS AND
RATIONALES (QUESTIONS 1-100)
1. What federal regulation mandates the training and accreditation of asbestos building inspectors?
A) OSHA 29 CFR 1910.134
B) EPA AHERA 40 CFR Part 763, Subpart E
C) NESHAP 40 CFR Part 61, Subpart M
D) TSCA Section 6
Answer: B
Rationale: The Asbestos Hazard Emergency Response Act (AHERA) and the Model Accreditation Plan
(MAP) under 40 CFR Part 763, Subpart E require that persons who inspect for asbestos in schools be
accredited through EPA-approved training courses .
2. Under AHERA, which types of buildings are required to have an asbestos management plan?
A) All public and commercial buildings
B) Only hospitals and medical facilities
C) All non-profit K-12 schools
D) Federal government buildings only
Answer: C
Rationale: AHERA specifically requires Local Education Agencies (LEAs) to inspect their schools for
asbestos-containing building materials (ACBM) and to develop, maintain, and update an asbestos
management plan .
3. What is the term friable asbestos-containing material mean?
A) Material that is resistant to crushing
B) Material that when dry, can be crumbled, pulverized, or reduced to powder by hand pressure
C) Material that contains more than 10% asbestos
D) Material that is only found in thermal systems insulation
,Answer: B
Rationale: Friability determines the potential for fiber release, which is critical for assessing health risks
and determining required control measures .
4. What is asbestos primarily composed of?
A) Silica
B) Carbon
C) Magnesium and silicon
D) Lead
Answer: C
Rationale: Asbestos is a group of naturally occurring silicate minerals containing magnesium and silicon
fibers, giving it heat and chemical resistance .
5. Which type of asbestos is considered the most hazardous to human health?
A) Chrysotile
B) Amosite
C) Crocidolite
D) Tremolite
Answer: C
Rationale: Crocidolite (blue asbestos) has fine, sharp fibers that are highly respirable and strongly linked
to mesothelioma .
6. What is the primary health risk associated with asbestos exposure?
A) Skin irritation
B) Respiratory diseases
C) Eye infections
D) Neurological disorders
Answer: B
Rationale: Inhalation of asbestos fibers can cause lung cancer, asbestosis, and mesothelioma .
,7. The EPA requires asbestos inspections for which type of buildings?
A) Residential homes built before 1980
B) Commercial and public buildings built before 1981
C) Only schools built after 1990
D) Industrial sites only
Answer: B
Rationale: Federal regulations require inspections in pre-1981 commercial and public buildings under
ASHARA .
8. Which method is used to identify asbestos in the laboratory?
A) X-ray diffraction
B) Polarized light microscopy (PLM)
C) Mass spectrometry
D) Gas chromatography
Answer: B
Rationale: PLM is the standard method for identifying asbestos fibers in bulk materials .
9. What is the minimum number of bulk samples required for a homogeneous area of surfacing material
greater than 1,000 square feet under AHERA?
A) 1 sample
B) 3 samples
C) 5 samples
D) 7 samples
Answer: D
Rationale: AHERA requires at least seven bulk samples from each homogeneous area of friable surfacing
material greater than 1,000 square feet .
10. What is the minimum number of bulk samples required for a homogeneous area of surfacing
material less than 1,000 square feet?
A) 1 sample
, B) 3 samples
C) 5 samples
D) 7 samples
Answer: B
Rationale: AHERA requires at least three bulk samples from each homogeneous area of friable surfacing
material that is 1,000 square feet or less .
11. The Asbestos School Hazard Abatement Reauthorization Act (ASHARA) extended AHERA training and
accreditation requirements to which types of buildings?
A) Only K-12 public schools
B) All residential homes
C) Public and commercial buildings
D) Federal courthouses
Answer: C
Rationale: ASHARA (1990) extended the Model Accreditation Plan (MAP) to cover inspectors,
management planners, and workers/supervisors in public and commercial buildings .
12. Under AHERA, a homogeneous area is defined as:
A) An area where all building materials are identical in color and texture
B) An area of building materials that is uniform in color, texture, and date of installation
C) An area with identical HVAC zoning
D) A room that has been previously abated
Answer: B
Rationale: Homogeneous areas are the basis for sampling under AHERA; materials in the same
homogeneous area are assumed to be the same type .
13. Who is responsible for ensuring that an accredited inspector performs the initial AHERA inspection?
A) The building principal
B) The Local Education Agency (LEA)
C) The EPA regional office
