LICENSING EXAM
1. What is the primary health hazard associated with
asbestos exposure?
A. Skin irritation
B. Asbestosis, lung cancer, and mesothelioma
C. Hearing loss
D. Liver disease
Answer: B
Rationale: Asbestos fibers, when inhaled, can become
lodged in lung tissue and over time cause serious diseases
including asbestosis (lung scarring), lung cancer, and
mesothelioma, which is a rare cancer of the lining of the
lungs or abdomen.
2. Which agency regulates asbestos standards in the
workplace in the United States?
A. EPA only
B. OSHA only
C. EPA and OSHA
D. CDC
Answer: C
Rationale: Both the Environmental Protection Agency (EPA)
and the Occupational Safety and Health Administration
(OSHA) regulate asbestos, with EPA focusing on
environmental exposure and OSHA focusing on worker
safety.
3. What is the most common method used to identify
asbestos-containing materials (ACM)?
, A. Smell testing
B. Visual inspection only
C. Laboratory analysis of bulk samples
D. Magnetic testing
Answer: C
Rationale: Asbestos cannot be reliably identified by sight
alone; laboratory analysis using polarized light microscopy
(PLM) or similar methods is required.
4. Which type of asbestos is considered the most commonly
used in commercial products?
A. Crocidolite
B. Amosite
C. Chrysotile
D. Tremolite
Answer: C
Rationale: Chrysotile, also known as white asbestos, is the
most widely used type in commercial and industrial
applications due to its flexibility and heat resistance.
5. What is the purpose of negative air pressure during
asbestos abatement?
A. To cool the work area
B. To prevent asbestos fibers from leaving the
containment area
C. To increase airflow for workers
D. To dry materials faster
Answer: B
Rationale: Negative air pressure ensures that air flows into
the containment area rather than out, preventing asbestos
fibers from escaping into uncontaminated spaces.
,6. Which respiratory protection is typically required during
asbestos abatement?
A. Dust mask
B. Surgical mask
C. NIOSH-approved respirator
D. No respiratory protection needed
Answer: C
Rationale: Workers must use NIOSH-approved respirators,
often including HEPA-filtered half-face or full-face
respirators depending on exposure levels.
7. What does ACM stand for?
A. Air Contamination Material
B. Asbestos Containment Measure
C. Asbestos-Containing Material
D. Active Control Material
Answer: C
Rationale: ACM refers to any material that contains more
than 1% asbestos as defined by regulatory standards.
8. What is the first step in an asbestos abatement project?
A. Disposal of waste
B. Removal of protective gear
C. Site preparation and containment setup
D. Painting the area
Answer: C
Rationale: Proper abatement begins with site preparation,
including containment, signage, and isolation of the work
area.
9. Which document outlines safety procedures for asbestos
work?
, A. OSHA Safety Manual
B. Site-Specific Abatement Plan
C. Building Code Handbook
D. Fire Safety Plan
Answer: B
Rationale: A site-specific abatement plan details
procedures, controls, and safety measures for a particular
asbestos project.
10. What is the purpose of HEPA filters in asbestos work?
A. Heating air
B. Cooling air
C. Capturing microscopic asbestos fibers
D. Increasing humidity
Answer: C
Rationale: HEPA filters are designed to capture at least
99.97% of particles 0.3 microns in size, including asbestos
fibers.
11. What is the permissible exposure limit (PEL) for
asbestos set by OSHA?
A. 1 fiber/cc
B. 0.1 fiber/cc
C. 5 fibers/cc
D. 0.5 fiber/cc
Answer: B
Rationale: OSHA has set the PEL for asbestos at 0.1 fibers
per cubic centimeter of air as an 8-hour time-weighted
average.
12. What is friable asbestos?
A. Asbestos that is painted over
