Question 1: What type of material is asbestos?
A) Synthetic polymer
B) Naturally occurring fibrous silicate
C) Metallic compound
D) Organic fiber
Answer: B) Naturally occurring fibrous silicate
Rationale: Asbestos is a group of naturally occurring minerals with fibrous structures ().
Question 2: What is the primary health risk from asbestos exposure?
A) Skin irritation
B) Inhalation of fibers into the lower lung
C) Gastrointestinal upset
D) Eye damage
Answer: B) Inhalation of fibers into the lower lung
Rationale: Inhaled asbestos fibers cause lung diseases like mesothelioma and asbestosis ().

compared to non-smoking, non-asbestos workers?
A) 10 times
B) 25 times
C) 50 times
D) 100 times
Answer: C) 50 times

Question 4: Which asbestos-related disease is always terminal and caused by the smallest fibers?
A) Lung cancer
B) Asbestosis
C) Mesothelioma
D) Pleural plaques
Answer: C) Mesothelioma
Rationale: Mesothelioma, a cancer of the lung or abdominal lining, is terminal and linked to fine
fibers ().

A) 0.01 f/cc
, B) 0.1 f/cc
C) 1.0 f/cc
D) 10 f/cc
Answer: B) 0.1 f/cc
