1. What is the primary purpose of an asbestos inspection before renovation or demolition?
A. To determine the building's market value
B. To identify asbestos-containing materials (ACM) that may be disturbed
C. To measure indoor humidity
D. To determine the age of the building
Correct Answer: B. To identify asbestos-containing materials (ACM) that may be disturbed
Rationale: A pre-renovation or demolition inspection is intended to locate and characterize ACM
that could be disturbed by the planned work.
2. Under California asbestos regulations, who is generally qualified to conduct an asbestos
inspection requiring professional certification?
A. Any building occupant
B. A certified asbestos consultant or other appropriately qualified professional
C. A general laborer
D. A property manager without asbestos training
Correct Answer: B. A certified asbestos consultant or other appropriately qualified
professional
Rationale: California requires appropriately trained and certified personnel for regulated
asbestos inspection and consulting activities.
3. Which type of asbestos is commonly called "white asbestos"?
A. Amosite
B. Crocidolite
C. Chrysotile
D. Anthophyllite
Correct Answer: C. Chrysotile
Rationale: Chrysotile is the serpentine form of asbestos and is commonly known as white
asbestos.
,4. Which asbestos mineral is commonly called "brown asbestos"?
A. Chrysotile
B. Amosite
C. Crocidolite
D. Tremolite
Correct Answer: B. Amosite
Rationale: Amosite is an amphibole asbestos commonly referred to as brown asbestos.
5. Which asbestos type is commonly known as "blue asbestos"?
A. Crocidolite
B. Chrysotile
C. Amosite
D. Actinolite
Correct Answer: A. Crocidolite
Rationale: Crocidolite is the amphibole asbestos commonly known as blue asbestos.
6. What analytical method is commonly used to identify asbestos in bulk building-material
samples?
A. Polarized light microscopy
B. Infrared thermometer
C. Sound-level measurement
D. Gas chromatography only
Correct Answer: A. Polarized light microscopy
Rationale: PLM is a standard method for identifying asbestos fibers and associated minerals in
bulk samples.
7. What does PLM stand for?
A. Particle Level Measurement
B. Polarized Light Microscopy
C. Personal Laboratory Monitoring
D. Polymer Light Measurement
Correct Answer: B. Polarized Light Microscopy
Rationale: PLM uses polarized light properties to help identify mineral fibers in bulk materials.
8. Why is representative sampling important during an asbestos inspection?
, A. It reduces the need for documentation
B. It ensures the samples reasonably represent homogeneous materials
C. It eliminates laboratory analysis
D. It guarantees that no asbestos exists
Correct Answer: B. It ensures the samples reasonably represent homogeneous materials
Rationale: Proper representative sampling helps determine whether a homogeneous material
contains asbestos.
9. What is a homogeneous area?
A. An area containing only one room
B. An area where material is uniform in composition, color, texture, and application as
applicable
C. Any area larger than 1,000 square feet
D. A room with no occupants
Correct Answer: B. An area where material is uniform in composition, color, texture, and
application as applicable
Rationale: Homogeneous-area concepts are used to develop appropriate sampling strategies.
10. What is friable asbestos-containing material?
A. Material that cannot contain asbestos
B. Material that, when dry, can be crumbled, pulverized, or reduced to powder by hand
pressure
C. Material that is always wet
D. Material containing only chrysotile
Correct Answer: B. Material that, when dry, can be crumbled, pulverized, or reduced to
powder by hand pressure
Rationale: Friability is based on the material's ability to be crumbled or pulverized by hand when
dry.
11. Which material is an example of potentially friable ACM?
A. Intact asbestos-containing thermal insulation
B. Steel framing
C. Glass window
D. Concrete foundation
