1. What is the primary responsibility of an asbestos supervisor
during an abatement project?
A. Collecting bulk samples for laboratory analysis
B. Ensuring the project is performed safely and according to
regulations
C. Designing asbestos management plans
D. Performing only final clearance air monitoring
Rationale: The asbestos supervisor is responsible for overseeing
workers, enforcing safety procedures, ensuring compliance with
regulations, and maintaining proper work practices during abatement
activities.
2. Before beginning asbestos abatement work, a supervisor must
verify that workers have:
A. Only received respiratory protection training
B. Current required asbestos training and certifications
C. Completed a construction apprenticeship
D. Passed a medical examination only
Rationale: Supervisors must confirm that all workers have current
training and certifications required by applicable asbestos regulations
before allowing them to perform regulated activities.

, 3. The main purpose of establishing a negative pressure enclosure is
to:
A. Reduce worker fatigue
B. Improve lighting conditions
C. Prevent asbestos fibers from escaping the work area
D. Increase ventilation to occupied spaces
Rationale: Negative pressure keeps contaminated air inside the
containment area and prevents migration of airborne asbestos fibers
to clean areas.
4. Which device is used to maintain negative air pressure inside an
asbestos containment?
A. HEPA vacuum
B. Negative air machine
C. Wetting sprayer
D. Air compressor
Rationale: Negative air machines equipped with HEPA filtration create
controlled airflow and maintain negative pressure within the
containment area.
5. A supervisor should ensure asbestos-containing materials are kept
wet because:
A. Wet materials weigh less
B. Wet materials are easier to store
C. Moisture reduces the release of airborne asbestos fibers
D. Water removes all asbestos hazards
Rationale: Wet methods minimize fiber release by preventing asbestos
materials from becoming easily airborne during disturbance.
6. OSHA requires employers to provide respiratory protection when:
2|Page
, A. Workers are uncomfortable without one
B. Airborne asbestos exposure exceeds permissible limits or during
certain activities
C. The building is older than 20 years
D. Workers request any type of mask
Rationale: Respiratory protection is required when exposure levels
exceed OSHA limits or when specific asbestos activities require
protection.
7. The OSHA permissible exposure limit (PEL) for asbestos is:
A. 5 fibers/cc as an 8-hour average
B. 2 fibers/cc as an 8-hour average
C. 0.1 fibers per cubic centimeter as an 8-hour time-weighted average
D. 1 fiber/cc as an 8-hour average
Rationale: OSHA establishes an asbestos PEL of 0.1 fibers per cubic
centimeter of air averaged over an 8-hour work shift.
8. Which respirator is commonly required for higher asbestos
exposure levels?
A. Dust mask
B. Surgical mask
C. Powered air-purifying respirator (PAPR) or appropriate higher
protection respirator
D. Cloth face covering
Rationale: Higher exposure levels require respirators with greater
assigned protection factors than simple negative-pressure respirators.
9. The purpose of a decontamination unit is to:
A. Store asbestos materials
B. Prevent the spread of asbestos contamination outside the work
