CSST STUDY GUIDE V1 questions well
answered
Why was asbestos added to construction materials ? - correct answer ✔✔ It was a great
insulator and binder. It added strength and durability against weathering and use. It was non-
corrosive, did not conduct electricity, and made spray-on products easier to apply.
What are the two classes of asbestos and their associated types? - correct answer ✔✔ The two
classes of asbestos are Serpentine and Amphiboles.
Serpentine consists of one type: Chrysotile.
Amphiboles consists of five types: Amosite, Crocidolite, Anthophyllite, Tremolite, Actinolite.
Of the different types of Amphiboles, which types were most commonly used commercially? -
correct answer ✔✔ Amosite and Crocidolite
What is the predominant color and structure of Chrysotile asbestos ? - correct answer ✔✔
white , long , curly , hollow
What is the predominant color and structure of Amosite asbestos ? - correct answer ✔✔ brown
/ tan ; long and straight
What is the predominant color and structure of Crocidolite ? - correct answer ✔✔ blue ; long
and straight
What is the definition of a Surfacing Material? - correct answer ✔✔ means material that is
sprayed-on, troweled-on, or otherwise applied to surfaces, such as acoustical plaster on ceilings
and fireproofing materials on structural members, or other materials on surfaces for acoustical,
fireproofing, or other purposes.
,What is the definition of Thermal Systems Insulation (TSI)? - correct answer ✔✔ means
material applied to pipes, fittings, boilers, breeching, tanks, ducts, or other interior structural
components to prevent heat loss or gain, or water condensation, or for other purposes.
What is the definition of a Miscellaneous Material? - correct answer ✔✔ means interior
building material that is not surfacing material or thermal system insulation.
What is the definition of Friable? - correct answer ✔✔ means that material, when dry, may be
crumbled, pulverized, or reduced to powder by hand pressure, and includes previously
nonfriable materials after such previously nonfriable material becomes damaged to the extent
that when dry it may be crumbled, pulverized, or reduced to powder by hand pressure.
What is the primary type of asbestos used in the U.S ? - correct answer ✔✔ Chrysotile.
List three building materials / locations where ACM is likely to be found - correct answer ✔✔
There are over 3000 building products that may contain asbestos. A limited list of examples are:
taping mud, flooring mastics/adhesives, popcorn ceilings, fireproofing, vinyl floor tiles, sheet
flooring backing, transite, fire doors, fume hoods, felt under roofs or siding, kiln bricks and
cement, lab equipment, fire safety equipment, auditorium curtains, gaskets, vibration joints,
HVAC duct tape, and many many more.
What are the 3 major diseases related to asbestos exposures ? - correct answer ✔✔ Asbestosis,
Lung Cancer, Mesothelioma.
What is a latency period ? What is the latency period for asbestos related illnesses ? - correct
answer ✔✔ The time between exposure to asbestos and the time symptoms appear. 10-40
years.
What asbestos-related disease normally appears only after prolonged, heavy, occupational
exposure to asbestos ? - correct answer ✔✔ Asbestosis
, What asbestos related disease primarily affects those exposed to asbestos who smoke
cigarettes? - correct answer ✔✔ Lung cancer. There is a synergistic effect that increases the
workers chances of getting lung cancer over 50 times.
Who must participate in a medical surveillance program? - correct answer ✔✔ 8 CCR1529 (m)
(1).
A. The employer shall institute a medical surveillance program for all employees who, for a
combined total of 30 or more days per year, are engaged in Class I, II, and III work or are
exposed at or above the permissible exposure limit. For purposes of this paragraph, any day in
which a worker engages in Class II or Class III operations or a combination thereof on intact
material for one hour or less (taking into account the entire time spent on the removal
operation, including cleanup) and, while doing so, adheres fully to the work practices specified
in this standard, shall not be counted.
B. For employees otherwise required by this standard to wear a negative pressure respirator,
employers shall ensure employees are physically able to perform the work and use the
equipment. This determination shall be made under the supervision of a physician.
When are asbestos medical surveillance physical exams required ? - correct answer ✔✔ 1. Prior
to assignment of the employee to an area where negative- pressure respirators are worn;
2. When the employee is assigned to an area where exposure to asbestos may be at or above
the permissible exposure limit for 30 or more days per year, or engage in Class I, II or III work for
a combined total of 30 or more days per year, a medical examination must be given within 10
working days following the thirtieth day of exposure;
3. And at least annually thereafter.
4. If the examining physician determines that any of the examinations should be provided more
frequently than specified, the employer shall provide such examinations to affected employees
at the frequencies specified by the physician.
