Q&A | Instant Download Pdf
1. Which material is most commonly associated with
asbestos exposure in buildings?
A. Vinyl flooring
B. Asbestos-containing insulation
C. Hardwood panels
D. Glass windows
Correct Answer: B
Rationale: Asbestos was widely used in thermal insulation
materials due to its heat resistance and fireproof properties,
making insulation a primary source of exposure.
2. What is the primary health risk associated with asbestos
exposure?
A. Skin rash
B. Liver disease
,C. Lung disease
D. Kidney infection
Correct Answer: C
Rationale: Asbestos fibers, when inhaled, can cause severe
respiratory conditions such as asbestosis, lung cancer, and
mesothelioma.
3. Which regulatory body oversees asbestos standards in
workplaces in the United States?
A. FDA
B. OSHA
C. USDA
D. FCC
Correct Answer: B
Rationale: The Occupational Safety and Health Administration
(OSHA) sets and enforces asbestos exposure standards in
occupational settings.
4. What is the best method for collecting bulk asbestos
samples?
A. Dry sweeping
B. Using a wet method with proper containment
,C. High-pressure air blowing
D. Vacuuming without a HEPA filter
Correct Answer: B
Rationale: Wetting materials reduces fiber release during
sampling, making it safer and more controlled.
5. Which type of asbestos is considered the most hazardous?
A. Chrysotile
B. Amosite
C. Tremolite
D. All are equally hazardous
Correct Answer: D
Rationale: All asbestos types are hazardous; risk depends on
exposure level and fiber characteristics rather than type alone.
6. What is the purpose of negative air pressure during
asbestos abatement?
A. Increase airflow into the area
B. Prevent fibers from escaping containment
C. Dry contaminated surfaces
D. Heat the workspace
, Correct Answer: B
Rationale: Negative pressure ensures contaminated air stays
inside the controlled zone, preventing fiber spread.
7. Which tool is commonly used for asbestos air sampling?
A. Hydrometer
B. Phase contrast microscope cassette pump
C. Barometer
D. Tachometer
Correct Answer: B
Rationale: Air pumps with filter cassettes collect airborne
fibers for analysis under phase contrast microscopy.
8. Asbestos is most dangerous when it is:
A. Painted over
B. Wet
C. Friable
D. Sealed in plastic
Correct Answer: C
Rationale: Friable asbestos can easily release fibers into the air
when disturbed.
