1. What is asbestos?
A. A synthetic polymer
B. A naturally occurring fibrous mineral group
C. A petroleum derivative
D. A metallic compound
Answer: B. A naturally occurring fibrous mineral group
Asbestos refers to several naturally occurring silicate minerals that
form long, thin, durable fibers.
2. Which characteristic makes asbestos particularly useful in
construction materials?
A. High electrical conductivity
B. Flammability
C. Resistance to heat and chemicals
D. Solubility in water
Answer: C. Resistance to heat and chemicals
Asbestos fibers have excellent heat resistance, chemical resistance,
strength, and durability.
3. Which asbestos mineral is characterized by curly, serpentine
fibers?
A. Amosite
B. Crocidolite
,C. Chrysotile
D. Anthophyllite
Answer: C. Chrysotile
Chrysotile is the principal serpentine asbestos mineral and has a
distinctive curled or tubular fiber structure.
4. Amosite is commonly referred to as:
A. White asbestos
B. Brown asbestos
C. Blue asbestos
D. Green asbestos
Answer: B. Brown asbestos
Amosite is commonly called brown asbestos and belongs to the
amphibole group.
5. Crocidolite is commonly called:
A. Blue asbestos
B. Brown asbestos
C. White asbestos
D. Gray asbestos
Answer: A. Blue asbestos
Crocidolite is an amphibole asbestos commonly referred to as blue
asbestos.
6. Which asbestos-related disease is a malignant tumor of the
mesothelial lining?
A. Asbestosis
B. Mesothelioma
C. Silicosis
D. Bronchitis
Answer: B. Mesothelioma
Mesothelioma is a cancer of mesothelial tissue, most commonly
involving the pleura.
,7. Asbestosis is best described as:
A. An infectious lung disease
B. A fibrotic lung disease caused by inhaled asbestos fibers
C. A skin allergy
D. A viral respiratory disease
Answer: B. A fibrotic lung disease caused by inhaled asbestos fibers
Asbestosis is a chronic, progressive pulmonary fibrosis associated
with significant asbestos exposure.
8. Which cancer has a well-established association with asbestos
exposure and cigarette smoking?
A. Lung cancer
B. Pancreatic cancer only
C. Skin cancer
D. Prostate cancer
Answer: A. Lung cancer
Asbestos exposure increases lung-cancer risk, and smoking can
substantially increase the combined risk.
9. The primary route of occupational asbestos exposure is:
A. Ingestion
B. Skin absorption
C. Inhalation
D. Eye contact
Answer: C. Inhalation
Airborne asbestos fibers can be inhaled deep into the respiratory
system.
10. Why can asbestos exposure produce disease many years after
exposure?
A. Asbestos immediately disappears from the body
B. Many asbestos-related diseases have long latency periods
, C. Fibers become radioactive
D. Exposure only affects children
Answer: B. Many asbestos-related diseases have long latency
periods
Diseases such as mesothelioma and lung cancer may develop
decades after exposure.
11. Which structure is primarily affected by pleural mesothelioma?
A. Liver
B. Pleural lining of the lung
C. Kidney
D. Bone marrow
Answer: B. Pleural lining of the lung
Pleural mesothelioma originates in the mesothelial lining surrounding
the lungs.
12. Friable asbestos-containing material is material that:
A. Contains no asbestos
B. Cannot be damaged
C. Can be crumbled, pulverized, or reduced to powder by hand
pressure when dry
D. Is always cementitious
Answer: C. Can be crumbled, pulverized, or reduced to powder by
hand pressure when dry
Friability describes how readily a material can release fibers when
subjected to mechanical force.
13. Which material is generally considered nonfriable when intact?
A. Sprayed fireproofing
B. Asbestos-containing cement board
C. Loose insulation
D. Fluffy thermal insulation
