1. What is the primary purpose of an asbestos inspection?
A. Determine property value
B. Identify asbestos-containing materials and assess condition
C. Repair damaged materials
D. Remove asbestos immediately
Answer: B
Rationale: The main goal of an asbestos inspection is to identify ACMs
and evaluate their condition to determine potential hazards.
2. Which method is commonly used to collect bulk samples of
suspected asbestos-containing materials?
A. Core drilling
B. Scraping or cutting a small portion
C. Sweeping
D. Spraying water
Answer: B
Rationale: Inspectors typically use hand tools to carefully collect small
samples of suspected ACM for lab analysis.
,3. What is the minimum number of bulk samples required per
homogeneous area in Texas?
A. 1
B. 2
C. 3
D. 5
Answer: C
Rationale: Texas regulations generally require at least 3 samples from
each homogeneous area to ensure representative analysis.
4. Which of the following materials is most likely to contain asbestos?
A. Vinyl flooring
B. Gypsum wallboard
C. Pipe insulation from the 1970s
D. Modern carpet
Answer: C
Rationale: Insulation installed before the 1980s commonly contains
asbestos; modern materials rarely do.
5. When inspecting a building, an inspector should assume that any
material is ACM unless proven otherwise. This approach is called:
A. Risk-based assessment
B. Presumptive assumption
C. Negative sampling
D. Visual estimation
,Answer: B
Rationale: The “presumptive assumption” ensures safety until lab
analysis confirms the material’s composition.
6. Which type of asbestos is most commonly found in building
materials?
A. Chrysotile
B. Amosite
C. Crocidolite
D. Tremolite
Answer: A
Rationale: Chrysotile (white asbestos) is the most common type used in
construction materials.
7. Which personal protective equipment (PPE) is required during
asbestos inspections?
A. Dust mask only
B. Half-mask respirator, gloves, disposable coveralls
C. Gloves only
D. Safety shoes only
Answer: B
Rationale: Proper PPE protects inspectors from airborne fibers during
sampling activities.
8. Which instrument is used to determine the concentration of
airborne asbestos fibers?
A. Optical microscope
, B. Transmission electron microscope (TEM)
C. Phase contrast microscope (PCM)
D. pH meter
Answer: C
Rationale: PCM is commonly used for airborne fiber counting in
occupational air samples.
9. A homogeneous area is defined as:
A. An area containing only one type of ACM in similar condition
B. An area of any size with multiple ACMs
C. A room with only wallboard
D. Any floor of a building
Answer: A
Rationale: Homogeneous areas are sections of materials that are similar
in type, texture, color, and condition.
10. How should bulk samples be labeled during collection?
A. Date, location, material type
B. Inspector’s name only
C. Building owner’s name only
D. No labeling is necessary
Answer: A
Rationale: Proper labeling ensures traceability and accurate analysis of
samples.
11. Asbestos-containing materials (ACMs) are regulated primarily
because they:
