1. What is asbestos primarily used for in building materials?
A. Electrical conductivity
B. Fire resistance and insulation
C. Decorative coloring
D. Structural reinforcement
Answer: B. Fire resistance and insulation
Rationale: Asbestos is valued for its heat resistance, durability, and
insulating properties. It was widely used in building materials such as
insulation, floor tiles, and cement products to reduce fire risk and
improve thermal performance.
2. Which of the following is the most common health risk associated
with asbestos exposure?
A. Skin rash
, B. Hearing loss
C. Respiratory diseases such as asbestosis
D. Liver damage
Answer: C. Respiratory diseases such as asbestosis
Rationale: Inhalation of asbestos fibers can lead to serious lung
conditions, including asbestosis, lung cancer, and mesothelioma.
These diseases are caused by fiber accumulation and long-term tissue
damage.
3. Which material is most likely to contain asbestos in older
buildings?
A. Tempered glass
B. Vinyl floor tiles
C. Aluminum siding
D. Plastic piping
Answer: B. Vinyl floor tiles
Rationale: Vinyl floor tiles manufactured before asbestos regulations
often contained asbestos for strength and fire resistance. Other
common materials include pipe insulation and ceiling tiles.
, 4. What is the primary purpose of an asbestos inspection?
A. To remove all building materials
B. To identify and assess asbestos-containing materials (ACMs)
C. To repaint hazardous surfaces
D. To replace HVAC systems
Answer: B. To identify and assess asbestos-containing materials
(ACMs)
Rationale: An asbestos inspection focuses on locating suspected ACMs,
evaluating their condition, and determining potential exposure risks,
not removal or renovation.
5. Which agency is commonly responsible for regulating asbestos in
the United States?
A. EPA
B. FDA
C. USDA
D. FCC
Answer: A. EPA
Rationale: The Environmental Protection Agency (EPA) regulates

, 6. What does ACM stand for in asbestos inspection terminology?
A. Airborne Contamination Measure
B. Asbestos Control Method
C. Asbestos-Containing Material
D. Approved Construction Material
Answer: C. Asbestos-Containing Material
Rationale: ACM refers to any material that contains more than 1%
asbestos and may pose a health risk if disturbed.
7. Which form of asbestos is considered the most commonly used in
construction?
A. Crocidolite
B. Amosite
C. Chrysotile
D. Tremolite
Answer: C. Chrysotile
Rationale: Chrysotile, or white asbestos, was the most widely used
type in construction due to its flexibility and heat resistance.
