1. The primary purpose of an asbestos building inspection is to:
A. Remove all asbestos-containing materials from a building
B. Identify, assess, and document asbestos-containing materials and
their condition
C. Determine the exact age of all building materials
D. Replace all suspect materials with non-asbestos products
Answer: B. Identify, assess, and document asbestos-containing
materials and their condition
Rationale: A certified asbestos building inspector’s primary
responsibility is to locate suspected asbestos-containing materials
(ACMs), determine their condition, assess potential hazards, and
document findings. Removal is performed by trained abatement
personnel, not inspectors.
2. Which federal regulation establishes requirements for asbestos
inspections in schools?
A. OSHA Hazard Communication Standard
B. EPA Asbestos Hazard Emergency Response Act (AHERA)

,C. Clean Air Act Title V
D. Resource Conservation and Recovery Act (RCRA)
Answer: B. EPA Asbestos Hazard Emergency Response Act (AHERA)
Rationale: AHERA established comprehensive asbestos inspection,
management planning, and response action requirements for public
and private elementary and secondary schools.
3. An asbestos inspector discovers damaged thermal system
insulation on a pipe. The material is friable. What should the
inspector do first?
A. Immediately remove the insulation
B. Spray water on the insulation and repair it
C. Document the condition and recommend appropriate corrective
action
D. Break off a sample for laboratory testing without controls
Answer: C. Document the condition and recommend appropriate
corrective action
Rationale: Inspectors identify and assess conditions but do not
perform unauthorized disturbance or removal. Damaged friable ACM
requires documentation and proper response planning.
4. A material is considered friable asbestos-containing material
when it:
A. Contains any visible asbestos fibers
B. Can be crumbled, pulverized, or reduced to powder by hand pressure
C. Is located outdoors
D. Was installed before 1980
2|Page
,Answer: B. Can be crumbled, pulverized, or reduced to powder by
hand pressure
Rationale: Friability describes how easily a material can release fibers.
Materials that can be crushed by hand pressure have a higher
potential for asbestos fiber release.
5. Which of the following materials commonly contained asbestos in
older buildings?
A. Vinyl floor tiles
B. Modern fiberglass insulation
C. Aluminum siding
D. Untreated wood framing
Answer: A. Vinyl floor tiles
Rationale: Vinyl floor tiles, mastics, adhesives, and backing materials
manufactured before asbestos restrictions commonly contained
asbestos.
6. During an asbestos inspection, homogeneous areas are
established primarily to:
A. Reduce laboratory costs by eliminating all sampling
B. Group materials with similar characteristics and potential asbestos
content
C. Identify building occupants
D. Determine the building’s structural design
Answer: B. Group materials with similar characteristics and potential
asbestos content
3|Page
, Rationale: Homogeneous areas allow inspectors to evaluate materials
that appear similar in composition, color, texture, and installation
history.
7. Which professional is generally responsible for collecting asbestos
bulk samples?
A. Building occupants
B. Certified asbestos inspector
C. General contractor
D. Maintenance worker
Answer: B. Certified asbestos inspector
Rationale: Certified asbestos inspectors are trained to identify suspect
materials and collect samples using proper methods to minimize fiber
release.
8. The most reliable method for determining whether a suspect
material contains asbestos is:
A. Visual inspection only
B. Building age estimation
C. Laboratory analysis of a properly collected sample
D. Material color comparison
Answer: C. Laboratory analysis of a properly collected sample
Rationale: Many asbestos-containing materials cannot be identified
accurately by appearance alone. Laboratory analysis is required for
confirmation.
