1. Which federal regulation primarily governs asbestos worker
training and certification requirements in schools?
A. OSHA Hazard Communication Standard
B. EPA Asbestos Hazard Emergency Response Act (AHERA)
C. DOT Hazardous Materials Regulations
D. Clean Water Act
Answer: B. EPA Asbestos Hazard Emergency Response Act (AHERA)
Rationale: AHERA established requirements for asbestos inspections,
management plans, and training of asbestos personnel working in
schools. OSHA regulations address worker protection, while AHERA
focuses on asbestos management in schools.
2. What is the primary health concern associated with asbestos
exposure?
A. Skin irritation
B. Hearing loss
C. Respiratory diseases and cancer
D. Vision impairment
Answer: C. Respiratory diseases and cancer

,Rationale: Inhalation of asbestos fibers can lead to serious illnesses
such as asbestosis, lung cancer, and mesothelioma. Health effects
often appear years after exposure.
3. Which agency regulates workplace asbestos exposure limits?
A. OSHA
B. FDA
C. EPA only
D. NRC
Answer: A. OSHA
Rationale: OSHA establishes and enforces workplace asbestos
standards, including permissible exposure limits, respiratory
protection, and work practices.
4. What type of asbestos-containing material (ACM) can easily
release fibers when disturbed?
A. Non-friable ACM
B. Friable ACM
C. Encapsulated ACM
D. Sealed ACM
Answer: B. Friable ACM
Rationale: Friable ACM can be crumbled, pulverized, or reduced to
powder by hand pressure, making fiber release more likely.
5. Before beginning asbestos removal work, a worker must first:

,A. Remove their respirator
B. Receive required asbestos training
C. Break materials into smaller pieces
D. Dry sweep the work area
Answer: B. Receive required asbestos training
Rationale: Texas asbestos workers must complete approved training
before performing regulated asbestos activities.
6. Which type of respirator is commonly required for asbestos
abatement?
A. Surgical mask
B. Dust mask
C. NIOSH-approved respirator
D. Cloth face covering
Answer: C. NIOSH-approved respirator
Rationale: Asbestos fibers are extremely small and require properly
selected and approved respiratory protection.
7. What is the purpose of a negative air machine in an asbestos
containment area?
A. Increase air pressure
B. Filter contaminated air and prevent fiber migration
C. Heat the work area
D. Remove moisture only
Answer: B. Filter contaminated air and prevent fiber migration
3|Page
, Rationale: Negative air machines maintain negative pressure and use
HEPA filtration to keep asbestos fibers from escaping the
containment.
8. HEPA filters are designed to remove particles approximately:
A. Larger than 1 inch
B. Only visible dust
C. Very small airborne particles
D. Water vapor
Answer: C. Very small airborne particles
Rationale: HEPA filters capture extremely small particles, including
asbestos fibers, with high efficiency.
9. What should workers do before leaving an asbestos containment
area?
A. Shake off clothing
B. Enter the decontamination area
C. Remove respirators immediately
D. Sweep the floor
Answer: B. Enter the decontamination area
Rationale: The decontamination process prevents asbestos fibers from
being carried into clean areas.
10. The purpose of wet methods during asbestos removal is to:
