CSST EXAM TESTBANK NEWEST ACTUAL EXAM COMPLETE 190 QUESTIONS
AND CORRECT DETAILED ANSWERS/NEWEST UPDATE!!!
Question 1
Why was asbestos historically added to such a wide variety of construction materials?
A) It was inexpensive and easily available in most regions.
B) It provided insulation, strength, durability, and electrical non-conductivity.
C) It acted as a natural pesticide to prevent termite infestations.
D) It was used primarily to improve the aesthetic color of cement.
E) It was required by the 1920 National Building Code for all residential homes.
Correct Answer: B) It provided insulation, strength, durability from weathering, made
spray on products easier to apply, and does not conduct electricity.
Rationale: Asbestos was known as the "magic mineral" because of its multi-functional
properties: it is a great thermal and electrical insulator, it adds tensile strength to
materials, and it is resistant to chemical and weather-related degradation.
Question 2
What are the two major mineral groups of asbestos and their associated species?
A) Serpentine (Amosite) and Amphiboles (Chrysotile).
B) Serpentine (Crocidolite) and Amphiboles (Chrysotile).
C) Serpentine (Chrysotile) and Amphiboles (Amosite and Crocidolite).
D) Silicates (Chrysotile) and Carbonates (Amosite).
E) Igneous (Chrysotile) and Metamorphic (Amosite).
Correct Answer: C) Chrysotile : Serpentine , Amosite and Crocidolites : amphiboles.
Rationale: Asbestos is divided into two mineralogic groups: Serpentine, which has a sheet-
like or layered structure (Chrysotile), and Amphibole, which has a chain-like structure
(Amosite, Crocidolite, etc.).
Question 3
Which of the following best describes the physical structure and color of Chrysotile asbestos?
A) Blue, long, and straight.
B) Brown, short, and brittle.
C) White, long, curly, and hollow.
D) Green, needle-like, and solid.
E) Grey, jagged, and flat.
Correct Answer: C) white , long , curly , hollow
Rationale: Chrysotile, the most common form of asbestos, is known as "white asbestos." Its
fibers are flexible, curly, and have a tubular (hollow) structure.
Question 4
A technician identifies a material that is long and straight in structure and has a distinct
brown/tan color. This is most likely:
A) Chrysotile.
, 2
B) Crocidolite.
C) Amosite.
D) Tremolite.
E) Actinolite.
Correct Answer: C) brown / tan ; long and straight
Rationale: Amosite is an amphibole asbestos often referred to as "brown asbestos." It is
characterized by its long, straight, needle-like fibers.
Question 5
"Blue asbestos" is the common name for which type of asbestos?
A) Amosite.
B) Chrysotile.
C) Anthophyllite.
D) Crocidolite.
E) Tremolite.
Correct Answer: D) blue ; long and straight
Rationale: Crocidolite is known as "blue asbestos." It is an amphibole with straight, thin
fibers and is considered one of the most hazardous types due to its fiber diameter.
Question 6
Which definition best describes "Surfacing Material" in the context of an asbestos inspection?
A) Material applied to pipes to prevent heat loss.
B) Material that is neither TSI nor miscellaneous.
C) Material sprayed, troweled, or otherwise applied to structural surfaces for acoustical or
decorative purposes.
D) Any material located on the exterior of a building.
E) Floor tiles and resilient sheet goods.
Correct Answer: C) is a sprayed on troweled on or otherwise applied to structural surfaces
EX: acoustic / decorative ceilings, fire proofing, textured paints and plasters.
Rationale: AHERA and OSHA define surfacing material as materials applied to surfaces
(walls, ceilings, beams) for fireproofing, acoustics, or decoration.
Question 7
Thermal Systems Insulation (TSI) is defined as material applied to which of the following?
A) Exterior siding and roofing shingles.
B) Pipes, fittings, tanks, and ducts to prevent heat loss or gain.
C) Interior decorative plaster and wallboard.
D) Only high-voltage electrical conduits.
E) Window glazing and door gaskets.
Correct Answer: B) applied to pipes, fittings, tanks, other structural, components etc. , to
prevent heat loss or gain. EX: pipe insulation, elbow mud, block insulation, air cell,
, 3
asbestos paper wrap, preformed halves, magnesium silica, etc
Rationale: TSI is a specific category of ACM used to control thermal energy, commonly
found on HVAC systems and boiler components.
Question 8
How are "Miscellaneous products" categorized in an asbestos survey?
A) Any material that contains less than 1% asbestos.
B) Material that is not TSI or surfacing but applied to structural components.
C) Only non-friable materials.
D) Materials that are exclusively found in residential basements.
E) Materials that have been identified but not yet sampled.
Correct Answer: B) material that is not TSI or surfacing but applied to structural
components.
Rationale: Under AHERA, miscellaneous materials are the "catch-all" category for items
like floor tiles, ceiling tiles, and gaskets that do not fit into the Surfacing or TSI categories.
Question 9
What is the primary factor that determines if an asbestos-containing material is "friable"?
A) It contains more than 10% asbestos.
B) It was installed before 1981.
C) It can be crumbled, pulverized, or reduced to powder by hand pressure.
D) It has been damaged by water or fire.
E) It is located in a high-traffic public area.
Correct Answer: C) Friable asbestos will crumble , pulverize or otherwise release dust by
applying hand pressure.
Rationale: Friability is a measure of how easily a material releases fibers. If hand pressure
can crush it, it is friable and poses a higher inhalation risk.
Question 10
Why does OSHA generally avoid using the term "friable" in its regulations compared to the
EPA?
A) OSHA believes "friable" is too scientific for workers to understand.
B) Because tools used by workers can easily make non-friable materials friable.
C) OSHA only regulates surfacing materials, not miscellaneous materials.
D) The term "friable" is trademarked by the EPA.
E) OSHA regulations only apply to airborne fibers, not the material state.
Correct Answer: B) OSHA - because tools that are used by workers can easily make non
friable materials friable.
Rationale: While a floor tile might be non-friable by hand, a worker using a sander or saw
on it will create dust, making it effectively friable. Therefore, OSHA focuses on the activity
rather than just the initial state.

Question 11
Which type of asbestos is the most commonly used in the United States?
A) Amosite.
B) Crocidolite.
C) Chrysotile.
D) Tremolite.
E) Actinolite.
Correct Answer: C) Chrysotile.
Rationale: Chrysotile accounts for approximately 90-95% of the asbestos used in
commercial applications in the United States.
Question 12
In which of the following building materials is ACM likely to be found?
A) Fire doors and fume hoods.
B) Auditoriums curtains and gaskets.
C) Felt under roofs or siding.
D) Kiln bricks and cement.
E) All of the above.
Correct Answer: E) fire doors, fume hoods, felt under roofs or siding, amosite sheeting, kiln
bricks and cement, lab equipment, fire safety and equipment, auditorium curtains, gaskets,
vibration joints, etc.
Rationale: Asbestos was ubiquitous in construction; it can be found in fire-rated assemblies,
laboratory equipment, roofing, and mechanical joints.
Question 13
What are the three major illnesses associated with asbestos exposure?
A) Asthma, Bronchitis, and Emphysema.
B) Asbestosis, Lung Cancer, and Mesothelioma.
C) Silicosis, Byssinosis, and Mesothelioma.
D) Hypertension, Lung Cancer, and Skin Cancer.
E) Asbestosis, Tuberculosis, and Lung Cancer.
Correct Answer: B) Asbestosis, Lung Cancer, Mesothelioma.
Rationale: The three primary health risks are Asbestosis (scarring of lung tissue), Lung
Cancer (malignancy of the lung), and Mesothelioma (cancer of the chest or abdominal
lining).
Question 14
What is the definition and typical range of the "latency period" for asbestos-related diseases?
A) The time it takes for asbestos to settle in a building; 1-5 years.
B) The time between exposure and the onset of symptoms; 10-40 years.
C) The duration of an abatement project; 30-60 days.
