1. Which federal agency primarily regulates occupational exposure to
asbestos in the workplace?
A. Environmental Protection Agency (EPA)
B. Occupational Safety and Health Administration (OSHA)
C. Department of Transportation (DOT)
D. Centers for Disease Control and Prevention (CDC)
Answer: B. Occupational Safety and Health Administration (OSHA)
Rationale: OSHA establishes workplace standards governing asbestos
exposure, including permissible exposure limits (PEL), respiratory
protection, medical surveillance, training, and work practices. The EPA
regulates environmental aspects of asbestos management, while OSHA
protects workers.
2. The primary purpose of a Texas Asbestos Worker Certification is
to:
A. License asbestos manufacturing facilities
B. Ensure workers are trained to safely perform asbestos-related
activities
1
,C. Authorize individuals to manufacture asbestos products
D. Certify building inspectors
Answer: B. Ensure workers are trained to safely perform asbestos-
related activities
Rationale: Texas certification ensures workers possess the knowledge
and skills needed to safely remove, encapsulate, transport, and dispose
of asbestos-containing materials while protecting themselves,
coworkers, and the public.
3. Which disease is most strongly associated exclusively with
asbestos exposure?
A. Tuberculosis
B. Silicosis
C. Mesothelioma
D. Pneumonia
Answer: C. Mesothelioma
Rationale: Mesothelioma is a rare cancer affecting the pleura or
peritoneum and is strongly linked to asbestos exposure. It has a long
latency period, often developing decades after exposure.
4. Friable asbestos-containing material (ACM) is defined as material
that:
A. Can dissolve in water
B. Can be crumbled, pulverized, or reduced to powder by hand pressure
when dry
C. Contains less than 1% asbestos
D. Is permanently sealed
2
,Answer: B. Can be crumbled, pulverized, or reduced to powder by
hand pressure when dry
Rationale: Friable ACM easily releases fibers into the air, making it
significantly more hazardous than nonfriable materials.
5. Which asbestos fiber type was historically used most frequently in
commercial products?
A. Crocidolite
B. Tremolite
C. Chrysotile
D. Anthophyllite
Answer: C. Chrysotile
Rationale: Chrysotile (white asbestos) accounted for the majority of
asbestos used worldwide due to its flexibility and heat resistance.
6. The OSHA Permissible Exposure Limit (PEL) for asbestos is:
A. 5 fibers/cc
B. 1 fiber/cc
C. 0.1 fiber/cc as an 8-hour TWA
D. Zero fibers
Answer: C. 0.1 fiber/cc as an 8-hour TWA
Rationale: OSHA's PEL is 0.1 fibers per cubic centimeter of air
averaged over an eight-hour work shift. Employers must implement
controls to maintain exposures below this limit.
7. The Excursion Limit (EL) for asbestos exposure is:
3
, A. 10 fibers/cc over 15 minutes
B. 1 fiber/cc over 30 minutes
C. 0.5 fibers/cc over 30 minutes
D. 2 fibers/cc over 15 minutes
Answer: B. 1 fiber/cc over 30 minutes
Rationale: The OSHA Excursion Limit prevents short-term high
exposures by limiting airborne asbestos concentrations during any 30-
minute period.
8. Which engineering control is preferred before relying on
respiratory protection?
A. Dusting with compressed air
B. Wet methods
C. Dry sweeping
D. Increased production speed
Answer: B. Wet methods
Rationale: Wet methods significantly reduce airborne asbestos fibers
and are considered a primary engineering control before personal
protective equipment.
9. The main route of occupational asbestos exposure is:
A. Skin absorption
B. Eye contact
C. Inhalation
D. Ingestion only
Answer: C. Inhalation
