cause serious diseases such as asbestosis, lung cancer, and
mesothelioma.
2. Which disease is most strongly associated with asbestos exposure?
A. Asthma
B. Mesothelioma
C. Diabetes
D. Tuberculosis
Mesothelioma is a rare cancer directly linked to asbestos exposure
and affects the lining of the lungs or abdomen.
3. What is the first step before beginning asbestos abatement work?

D. No protection needed
Respirators with high-efficiency particulate filters are required to
prevent inhalation of asbestos fibers.
5. Why is wetting asbestos-containing material important?
A. To change its color
B. To increase dust
C. To reduce airborne fiber release
D. To speed up removal
Wetting materials minimizes the release of hazardous fibers into the
air.
6. What is the purpose of a regulated work area?
A. Increase airflow
B. Improve lighting
C. Contain asbestos fibers and prevent contamination
D. Reduce costs
Containment prevents asbestos fibers from spreading to clean areas.
7. What protective clothing is required during asbestos removal?

OSHA establishes worker safety standards for asbestos exposure.
11. What is the permissible exposure limit (PEL) for asbestos under
OSHA?
A. 1 fiber/cc
B. 0.1 fiber/cc
C. 0.1 fiber per cubic centimeter as an 8-hour TWA
D. 10 fibers/cc
OSHA sets strict exposure limits to protect workers from inhalation
risks.
12. What should be done before disturbing suspect materials?
A. Break them
B. Ignore them
C. Conduct proper asbestos inspection and testing
D. Spray paint them
Testing confirms whether materials contain asbestos before removal
