B. A group of naturally occurring fibrous minerals
C. A type of plastic insulation
D. A form of fiberglass
Correct Answer: B. A group of naturally occurring fibrous
minerals
Rationale: Asbestos refers to a group of naturally occurring
silicate minerals that separate into durable microscopic fibers.
These fibers are resistant to heat, chemicals, and electricity,
making them useful in many industrial and construction
applications.
,2. Which property contributed most to the widespread use of
asbestos?
A. It dissolves easily in water
B. It changes color when heated
C. It is resistant to heat and fire
D. It biodegrades rapidly
Correct Answer: C. It is resistant to heat and fire
Rationale: Asbestos was widely used because of its excellent
resistance to heat, fire, chemicals, and electrical conductivity,
making it suitable for insulation and fireproofing applications.
3. Which of the following is a recognized health effect
associated with asbestos exposure?
A. Broken bones
B. Kidney stones
C. Lung disease
D. Hearing loss
Correct Answer: C. Lung disease
Rationale: Inhalation of asbestos fibers can cause serious

C. Inhalation of airborne fibers
D. Injection
Correct Answer: C. Inhalation of airborne fibers
Rationale: The greatest risk occurs when asbestos fibers
become airborne and are inhaled into the lungs where they may
remain for many years.
5. What does ACM stand for?
A. Air Control Material
B. Asbestos Containing Material
C. Approved Construction Material
D. Airborne Contaminant Measurement

A. A skin infection
B. A chronic lung scarring disease
C. A liver disorder
D. A heart condition
Correct Answer: B. A chronic lung scarring disease
Rationale: Asbestosis is a progressive disease caused by
inhaling asbestos fibers that result in permanent scarring of
