1. What is the primary responsibility of an asbestos abatement
supervisor on a regulated project?
A. Performing only air monitoring activities
B. Ensuring that asbestos work is performed safely, legally, and
according to the approved work plan
C. Collecting all waste samples personally
D. Designing the building ventilation system
Rationale: The supervisor is responsible for overseeing asbestos
abatement activities, enforcing safety procedures, ensuring worker
compliance, and verifying that work follows applicable regulations
and project specifications.
2. Which federal regulation specifically governs asbestos operations
in construction workplaces?
A. EPA TSCA Title VI
B. DOT Hazardous Materials Regulations
C. OSHA 29 CFR 1926.1101
D. FDA Asbestos Control Standard
1|Page
,Rationale: OSHA 29 CFR 1926.1101 establishes requirements for
asbestos exposure protection in construction, including competent
person duties, work practices, respiratory protection, and training.
3. The main purpose of a negative air pressure enclosure is to:
A. Increase worker comfort
B. Reduce waste disposal costs
C. Prevent asbestos fibers from escaping the regulated work area
D. Eliminate the need for respirators
Rationale: Negative pressure keeps contaminated air inside the
enclosure by causing air to flow inward through openings rather than
allowing fibers to escape.
4. Which device is commonly used to maintain negative pressure
inside an asbestos enclosure?
A. HEPA vacuum
B. Negative air machine with HEPA filtration
C. Carbon monoxide detector
D. Humidifier
Rationale: Negative air machines create airflow through HEPA filters,
maintaining containment and removing airborne asbestos fibers from
the work area.
5. A supervisor must verify that workers are properly trained before:
A. Entering the building lobby
B. Starting any unrelated construction activity

,C. Beginning asbestos abatement work
D. Performing office cleaning
Rationale: Regulations require asbestos workers to complete
approved training before performing asbestos-related activities.
6. What is the purpose of a HEPA filter?
A. Remove moisture from the air
B. Increase airflow speed
C. Capture very small airborne particles, including asbestos fibers
D. Neutralize chemical vapors
Rationale: HEPA filters are designed to capture at least 99.97% of
particles at 0.3 microns, making them effective for asbestos control.
7. Which item is required inside a properly established asbestos
containment area?
A. Open windows
B. Standard household vacuum
C. Warning signs and regulated area boundaries
D. Unprotected electrical outlets
Rationale: Warning signs and controlled boundaries prevent
unauthorized entry and alert personnel to asbestos hazards.
8. The supervisor’s role as a competent person includes:
A. Ignoring unsafe practices unless injuries occur
B. Identifying hazards and correcting unsafe conditions

, C. Approving employee vacation schedules
D. Selecting building paint colors
Rationale: A competent person must recognize hazards and have
authority to take corrective action during asbestos operations.
9. Which respiratory protection is typically required when airborne
asbestos concentrations exceed permissible limits?
A. Surgical mask
B. Dust mask only
C. A properly selected and fitted respirator under a respiratory
protection program
D. Safety glasses only
Rationale: Respirators must meet OSHA requirements and be selected
according to exposure levels and assigned protection factors.
10. What is the OSHA permissible exposure limit (PEL) for
asbestos?
A. 5 fibers/cc as an 8-hour average
B. 1 fiber/cc as an 8-hour average
C. 0.1 fiber per cubic centimeter as an 8-hour time-weighted average
D. 10 fibers/cc as an 8-hour average
Rationale: OSHA established an asbestos PEL of 0.1 f/cc over an 8-
hour TWA period, with an excursion limit of 1.0 f/cc.
11. Which document identifies how asbestos work will be
performed on a project?
