2026/2027 | Guaranteed Pass | Graded A+.
1. Which federal regulation governs asbestos in schools?
A. NESHAP
B. TSCA Title VI
C. AHERA
D. FIFRA
Rationale: AHERA (Asbestos Hazard Emergency Response Act) is part of
TSCA and governs asbestos management in K–12 schools.
2. What is the permissible exposure limit (PEL) for asbestos according to
Cal/OSHA?
A. 0.2 f/cc over 30 minutes
B. 0.1 f/cc as an 8-hour TWA
C. 1.0 f/cc as a ceiling limit
D. 0.01 f/cc as a short-term limit
Rationale: The Cal/OSHA PEL for asbestos is 0.1 fibers per cubic centimeter
(f/cc) over an 8-hour time-weighted average.
3. The AHERA requirement for re-inspection of asbestos-containing
materials (ACMs) in schools is every:
A. 2 years
B. 3 years
C. 5 years
D. 6 months
Rationale: AHERA requires re-inspection of known or assumed ACMs in
schools every 3 years.
4. A friable material is best described as:
,A. A solid ACM in good condition
B. An ACM that can be crumbled or reduced to powder by hand pressure
C. A wet ACM
D. Any asbestos product used in cement
Rationale: Friable materials are easily crumbled and pose a higher
inhalation risk.
6. The NESHAP regulation is enforced under:
A. Clean Air Act
B. Safe Drinking Water Act
C. TSCA
D. RCRA
Rationale: NESHAP (National Emission Standards for Hazardous Air
Pollutants) is a Clean Air Act program.
7. The term "asbestos-containing material" (ACM) refers to materials with
at least:
A. 0.5% asbestos
B. 5% asbestos
C. 1% asbestos
D. 10% asbestos
Rationale: ACM is legally defined as containing more than 1% asbestos.
8. Clearance air monitoring after abatement must be performed using:
A. PLM
B. TEM (Transmission Electron Microscopy)
C. PCM
D. IR spectroscopy
Rationale: TEM is required for clearance air monitoring in schools under
AHERA.
9. Who may perform asbestos air clearance testing in California?
A. Any contractor
, B. Certified Asbestos Consultant (CAC) or Site Surveillance Technician
(CSST)
C. Building owner
D. Architect
Rationale: Only CACs or CSSTs certified by Cal/OSHA may perform clearance
sampling.
5. A PLM (Polarized Light Microscopy) analysis of bulk material is:
A. A method to detect asbestos in bulk building materials
B. A method to measure airborne fibers
C. Used for air monitoring
D. Not approved under AHERA
Rationale: PLM is used to identify asbestos type and content in bulk
materials.
10. Asbestos is most dangerous when:
A. Sealed in concrete
B. Airborne as friable fibers
C. In pipe insulation
D. Painted over
Rationale: Airborne friable fibers can be inhaled and are most hazardous.
11. Which of the following is not a method of asbestos abatement?
A. Removal
B. Encapsulation
C. Enclosure
D. Reinforcement
