Asbestos Building Inspector Examination
Question 1
Which statement best explains why a qualified asbestos building inspector must conduct
a thorough visual assessment before collecting any bulk material samples from
suspected asbestos-containing building components?
A. Because laboratory testing completely replaces visual observations during inspections
,B. Because visual assessment helps determine suspect materials, accessibility, condition,
and appropriate sampling locations while reducing unnecessary disturbance
C. Because visual inspections eliminate the need for laboratory analysis whenever
asbestos appears obvious
D. Because photographs alone satisfy all regulatory inspection requirements
Answer: B
Rationale: A careful visual inspection identifies suspect materials, their condition, and
appropriate sampling locations while minimizing fibre release and unnecessary
disturbance before sampling begins.
Question 2
During an inspection of an older commercial building, which asbestos-containing
material would most likely be classified as friable because it can easily be crumbled by
hand pressure when dry?
A. Vinyl asbestos floor tile
B. Cement asbestos siding
C. Thermal system insulation on pipes
D. Asphalt roofing shingles
Answer: C
Rationale: Thermal insulation on pipes is commonly friable and can readily release
fibres when disturbed.
Question 3
Which federal law primarily establishes requirements for asbestos inspections and
management plans in public and private non-profit elementary and secondary schools
throughout the United States?
,A. Clean Water Act
B. Resource Conservation and Recovery Act
C. Asbestos Hazard Emergency Response Act (AHERA)
D. Safe Drinking Water Act
Answer: C
Rationale: AHERA establishes inspection, reinspection, surveillance, and management
plan requirements for schools.
Question 4
An asbestos inspector discovers damaged pipe insulation inside a mechanical room.
What should be the inspector's immediate priority before continuing with additional
inspection activities?
A. Remove the insulation immediately
B. Prevent unnecessary disturbance, document the condition, and follow established
safety procedures
C. Sweep debris using a dry broom
D. Allow occupants unrestricted access
Answer: B
Rationale: Inspectors document hazards while minimizing fibre release and following
applicable safety procedures.
Question 5
Which asbestos fibre type has historically been the most commonly used in commercial
construction materials because of its heat resistance and durability?
A. Tremolite
, B. Chrysotile
C. Anthophyllite
D. Actinolite
Answer: B
Rationale: Chrysotile, or white asbestos, accounted for the majority of asbestos used in
commercial products.
Question 6
Why should an asbestos building inspector avoid collecting more samples than
necessary while still ensuring representative sampling throughout an inspection?
A. Because additional samples always invalidate laboratory results
B. Because excessive sampling unnecessarily disturbs materials while increasing
exposure risks and project costs
C. Because regulations prohibit collecting more than one sample
D. Because only photographs are legally acceptable evidence
Answer: B
Rationale: Representative sampling balances accuracy with minimizing disturbance and
unnecessary costs.
Question 7
Which disease is strongly associated with long-term occupational exposure to airborne
asbestos fibres and primarily affects the lining surrounding the lungs?
A. Tuberculosis
B. Mesothelioma
