QUESTIONS AND VERIFIED ANSWERS ALL THE BEST
What is Asbestosis
Asbestosis is a condition developed in the lungs as a result of inhalation of
asbestosis fibers.
What is AHERA?
Asbestos Hazard Emergency Response Act
What is the dose-response relationship with asbestos and cancer?
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?
Asbestosis
What can a B-reader do?
Interpret Chest X-rays
What is Title 8 CCR 5208 and 29 CFR 1910.1001?
General Industry
What is plenum space?
An enclosed space that is used for airflow. Example: the area above a drop ceiling.
What is fibrosis?
formation of scar tissue in the lungs
What is mesothelioma?
Cancer that arises from the mesothelial cells of the pleura is caused by asbestos
fibers
, 2
What type of encapsulation forms a "hard shell" or membrane over the surface?
Bridging encapsulation
What type encapsulation does not leave a discreet surface layer?
Penetrating encapsulation
Bridging Encapsulant
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
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?
13mm (1/2 inch)
Removal Encapsulant
Penetrating encapsulant specifically designed to minimize fiber release during
removal of asbestos-containing materials rather than for encapsulation.
Encapsulate
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)
, 3
or by penetrating into the material and binding it's components together
(Penetrating encapsulant)
what is ACBM?
Asbestos Containing Building Material (interior and >1%)
What is ACCM?
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...
400 point count
When a school has friable asbestos they...?
Must implement an Asbestos Management Plan with yearly notification to any
changes in ACM conditions
What is ACM?
Asbestos-containing material is defined as any material containing more than 1%
asbestos; >1%.
Non-friable Asbestos Containing Material (ACM) is considered hazardous.
False.
Non-friable asbestos can become friable.
Through Mechanical (power tools) means during removal.
Non-friable asbestos waste require a DOT manifest.
False.
, 4
An EPA ID is not required with non-friable asbestos waste. However proper
documentation is still required.
ACCM waste requires a DOT manifest.
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?
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
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
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
blue asbestos - was commonly used to insulate steam engines. It was also used in
some spray-on coatings, pipe insulation, plastics, and cement products
