1. What is the primary health hazard associated with inhaling asbestos fibers?
A. Liver failure
B. Asbestosis and asbestos-related cancers
C. Hearing loss
D. Skin burns
Rationale: Inhalation of respirable asbestos fibers can cause asbestosis, lung
cancer, and mesothelioma. These diseases may develop decades after exposure.
2. Which characteristic makes asbestos particularly hazardous during
renovation or demolition?
A. It dissolves rapidly in water
B. It is highly flammable
C. It can release microscopic airborne fibers when disturbed
D. It produces a strong odor
Rationale: Disturbing asbestos-containing materials can release fibers that
remain airborne and can be inhaled.
, 3. Which disease is strongly associated with occupational asbestos exposure?
A. Silicosis
B. Mesothelioma
C. Tuberculosis
D. Asthma
Rationale: Mesothelioma is a cancer of the lining of the lungs or other organs
and is strongly associated with asbestos exposure.
4. What is the primary responsibility of an asbestos supervisor?
A. Perform only administrative paperwork
B. Direct and oversee asbestos-related work so that regulatory and safety
requirements are followed

D. Determine employee salaries

A. Material that cannot contain asbestos
B. Material that is always wet
C. Material that can be crumbled, pulverized, or reduced to powder by hand
pressure when dry
D. Material that is made only of cement
Rationale: Friability is important because materials that can readily release
fibers when disturbed present a significant exposure concern.
8. Which material is generally considered more likely to become friable when
damaged?
A. Intact metal flashing
B. Sprayed-on asbestos insulation
C. Glass window
D. Steel beam
Rationale: Sprayed or applied insulation can be highly friable, particularly when
deteriorated or disturbed.
9. What is the purpose of a regulated asbestos work area?
A. To store ordinary construction materials
B. To restrict access and control potential asbestos exposure
