1. Which California regulation primarily governs asbestos work
practices for construction activities?
A. EPA NESHAP
B. Cal/OSHA Title 8 §1529
C. AHERA
D. TSCA
Correct Answer: B
Cal/OSHA Title 8 §1529 specifically regulates asbestos exposure and
work practices in California construction activities.
2. The permissible exposure limit (PEL) for asbestos in California is:
A. 1.0 fibers/cc
B. 0.5 fibers/cc
C. 0.1 fibers/cc
D. 0.01 fibers/cc
Correct Answer: C
The Cal/OSHA PEL for asbestos is 0.1 fibers per cubic centimeter (f/cc) as
an 8-hour time-weighted average.
,3. The excursion limit (EL) for asbestos exposure over 30 minutes is:
A. 1.0 f/cc
B. 0.5 f/cc
C. 0.2 f/cc
D. 0.1 f/cc
Correct Answer: A
The excursion limit is 1.0 f/cc averaged over a 30-minute period.
4. Which agency enforces asbestos waste disposal regulations in
California?
A. Cal/OSHA
B. DTSC
C. CARB
D. EPA only
Correct Answer: B
The California Department of Toxic Substances Control (DTSC) oversees
hazardous waste disposal, including asbestos-containing waste.
5. Friable asbestos-containing material (ACM) is defined as material
that:
A. Contains more than 10% asbestos
B. Can be crumbled by hand pressure
C. Is found only in insulation
D. Is always sprayed-on material
,Correct Answer: B
Friable ACM can be crumbled, pulverized, or reduced to powder by hand
pressure when dry.
6. Class I asbestos work involves:
A. Maintenance operations
B. Removal of thermal system insulation (TSI) and surfacing ACM
C. Custodial cleanup
D. Encapsulation only
Correct Answer: B
Class I work involves removal of TSI and surfacing ACM, which presents
the highest exposure risk.
7. AHERA applies primarily to:
A. Private residences
B. Commercial warehouses
C. Public and private K-12 schools
D. Industrial refineries
Correct Answer: C
The Asbestos Hazard Emergency Response Act (AHERA) regulates
asbestos management in K-12 schools.
8. A negative exposure assessment (NEA) allows:
, A. Elimination of all PPE
B. Work without containment
C. Reduced monitoring requirements
D. Disposal without labeling
Correct Answer: C
An NEA demonstrates exposures are below the PEL, allowing reduced
monitoring and some control adjustments.
9. HEPA filters must remove at least what percentage of particles 0.3
microns in size?
A. 95%
B. 97%
C. 99%
D. 99.97%
Correct Answer: D
HEPA filters are required to capture 99.97% of particles at 0.3 microns.
10. A regulated area must be established when:
A. ACM is present in a building
B. Exposure may exceed the PEL
C. Any demolition occurs
D. Waste is transported
Correct Answer: B
Regulated areas are required where airborne concentrations may
exceed the PEL.
