CALIFORNIA CSST EXAM) EXAM 2025
QUESTIONS AND ANSWERS
What is Title 8 CCR 5208 and 29 CFR 1910.1001? - ANS General Industry
What is plenum space? - ANS An enclosed space that is used for airflow. Example: the area
above a drop ceiling.
What is fibrosis? - ANS formation of scar tissue in the lungs
What is mesothelioma? - ANS Cancer that arises from the mesothelial cells of the pleura is
caused by asbestos fibers
What is Asbestosis - ANS Asbestosis is a condition developed in the lungs as a result of
inhalation of asbestosis fibers.
What is AHERA? - ANS Asbestos Hazard Emergency Response Act
What is the dose-response relationship with asbestos and cancer? - ANS The correlation
between exposure to asbestos and disease (i.e. cumulative effect of high exposure and short
duration or chronic exposure over longer duration)
What is the most common asbestos related disease? - ANS Asbestosis

,What can a B-reader do? - ANS Interpret Chest X-rays
What type of encapsulation forms a "hard shell" or membrane over the surface? -
ANS Bridging encapsulation
What type encapsulation does not leave a discreet surface layer? - ANS Penetrating
encapsulation
Bridging Encapsulant - ANS The type of encapsulation that forms a hard shell on the outside
of asbestos-containing material is called a (n):
(ex. If used on soil it would form a hard layer over the soil that would break if disturbed)
Penetrating Encapsulant - ANS The type of encapsulant that is absorbed into the asbestos
matrix, and binds the components together. (n):
(ex. If used on soil it would be absorbed and then form a lump of hardened material)
How far does penetrating encapsulant penetrate? - ANS 13mm (1/2 inch)
Removal Encapsulant - ANS Penetrating encapsulant specifically designed to minimize fiber
release during removal of asbestos-containing materials rather than for encapsulation.
Encapsulate - ANS A liquid material which can be applied to asbestos-containing material
which controls the possible release of asbestos fibers from the material either by creating a
membrane over the surface (Bridging encapsulant)

,or by penetrating into the material and binding it's components together (Penetrating
encapsulant)
what is ACBM? - ANS Asbestos Containing Building Material (interior and >1%)
What is ACCM? - ANS Asbestos Containing Construction Material (>0.1%; greater than one-
tenth of one percent by weight)
This is defined by Cal-OSHA
ACCM must be verified by at least... - ANS 400 point count
When a school has friable asbestos they...? - ANS Must implement an Asbestos Management
Plan with yearly notification to any changes in ACM conditions
What is ACM? - ANS Asbestos-containing material is defined as any material containing more
than 1% asbestos; >1%.
Non-friable Asbestos Containing Material (ACM) is considered hazardous. - ANS False.
Non-friable asbestos can become friable. - ANS Through Mechanical (power tools) means
during removal.
Non-friable asbestos waste require a DOT manifest. - ANS False.
An EPA ID is not required with non-friable asbestos waste. However proper documentation is
still required.

, ACCM waste requires a DOT manifest. - ANS False. Although, it can be hauled with general
demolition debris the receiving waste facility should be notified prior to receiving waste in
order to properly secure the waste.
How long does Asbestos stay in the air? - ANS 48-72 hours to settle.
(Theoretically, it could stay airborne indefinitely as any disturbance to the airborne fiber can
cause it to rise back into the breathing zones.)
Chrysotile - ANS White asbestos - is the most commonly used form of asbestos. It can be
found today in the roofs, ceilings, walls, and floors of homes and businesses. Manufacturers
also used chrysotile asbestos in automobile brake linings, gaskets and boiler seals, and
insulation for pipes, ducts, and appliances.
Estimated to be used in at least 80% of building materials.
Amosite asbestos - ANS brown asbestos - was used most frequently in cement sheets and
pipe insulation. It can also be found in insulating boards, ceiling tiles, and thermal insulation
products
Crocidolite asbestos - ANS blue asbestos - was commonly used to insulate steam engines. It
was also used in some spray-on coatings, pipe insulation, plastics, and cement products
Anthophyllite Asbestos - ANS was used in limited quantities for insulation products and
construction materials. It also occurs as a contaminant in chrysotile asbestos, vermiculite, and
talc. It may have a grey, dull green, or white color
Tremolite and actinolite - ANS are not used commercially, but they can be found as
contaminants in chrysotile asbestos, vermiculite and talc. These two chemically similar minerals
can be brown, white, green, gray or transparen
