CSST STUDY GUIDE V1 Exam Questions AND Correct Answers
A contractor is going to remove floor tile and mastic from a large single room.
The dimensions of the room is 50' wide, 100' long, and 20' high. They intend to
use negative air machines that can pull 2000 cubic feet per minute (cfm).
What is the quantity of floor tile and mastic to be removed?
What is the volume of air in the room?
How many negative air machines will they need to use to get a minimum of 4 air
changes per hour (ACH)? - ✔✔They are removing 5,000 square feet of floor tile
and 5,000 square feet of floor tile mastic.
There is 100,000 cubic feet of air in the room.
Assuming there is good air circulation in the room and the negative air machines
really are pulling 2000 cfm, they will need a minimum of 4 negative air machines
to get 4 air changes an hour.
According to 40 CFR 763 what is the definition of an asbestos fiber? - ✔✔A
structure greater than or equal to 0.5 microns in length with an aspect ratio of
5:1 or greater and having substantially parallel sides.
According to 8 CCR 5144 your employer is required to establish and retain
written records pertaining to what? - ✔✔Your medical evaluations, fit tests, and
the respiratory protection program.
According to AHERA, are bulk samples required to be collected of TSI that
appears to be fiberglass, foam glass, rubber, or other non-ACBM? - ✔✔No, as
long as an accredited inspector has made the determination that they are non-
ACBM.
,According to AHERA, how many samples should you collect of 600 square feet of
a miscellaneous material? - ✔✔In a manner sufficient to determine according to
AHERA.
According to AHERA, what information is required to be reported to the
representative of the local education agency within 30 days of an inspection? -
✔✔1. Inspection report with the date of the inspection signed by each
accredtied person maing the inspectin, state of accreditation, and if applicable,
his/her accreditation number.
2.An inventory of the locations of the homogeneous areas where samples are
collected, exact locations, dates, and areas of assumed ACMs.
3. Methodology for collection of the samples
4. List of materials and their type (TSI, surfacing or misc.)
5. Assessments of friable materials
According to CalOSHA how often should you have a chest roentgenogram (X-
ray) - ✔✔Years since first occupational exposure:
0-10 years - Once every three years if under 40 years old. Annually if 40 years
old or over.
10+ years - Annually
According to NESHAP what is a 'visible emission'? - ✔✔Means any emissions
which are visually detectable without the aid of instruments, coming from
RACM or asbestos-containing waste material. This does not include condensed,
uncombined water vapor.
According to NESHAP, what does 'adequately wet' mean? - ✔✔Means
sufficiently mix or penetrate with liquid to prevent the release of particulates. if
,visible emissions are observed coming from the asbestos-containing material,
then that material has not been adequately wetted. However, the absence of
visible emissions is not sufficient evidence of being adequately wet.
According to NESHAP, what is the definition of 'demolition'? - ✔✔means the
wrecking or taking out of any load-supporting structural member of a facility
together with any related handling operations or the intentional burning of any
facility. (So, demolition doesn't necessarily mean a building is coming down. It
could just be a load-bearing wall inside a building. The removal of a non-load
bearing wall inside a facility would not be demolition, according to the
regulation.)
According to NIOSH Method 7400, what is the definition of a fiber? - ✔✔Greater
than five microns in length with a length to width ratio equal to or greater than
3:1.
According to the California Business and Professions Code no person may
contract to provide professional health and safety services related to asbestos-
containing material unless what? - ✔✔They must be a CAC or CSST working
under the direction of a CAC that has been certified by DOSH.
According to the California Business and Professions Code when can a
contractor collect bulk samples, but not need to be a CAC or CSST to do it? -
✔✔When a contractor or registered asbestos abatement contractor takes no
more than 12 bulk samples of suspected asbestos-containing material that is
required to be removed, repaired, or disturbed as part of a construction project
in a residential dwelling solely for any of the following purposes:
1. Bid preparation for asbestos abatement
2. Evaluating exposure to its own employees during construction or abatement;
or
, 3. Determining for its own purposes of for the purpose of communicating
whether or not a contract for asbestos abatement has been satisfactorily
completed.
AHERA determines the minimum number of samples of surfacing material that
must be collected in a statistically random manner to determine it does not
contain asbestos based on square footage. What are they? - ✔✔For less than
1000 sq. ft. collect a minimum of 3
Between 1000 and 5000 sq. ft. collect a min. of 5
For greater than 5000 sq. ft. collect a min. of 7
An asbestos inspection is considered what class of work? - ✔✔Class III
Are Class II asbestos abatement projects required to be performed under
negative pressure according to CalOSHA? - ✔✔No.
Are other microscope methods used for asbestos analysis? - ✔✔Transmission
Electron Microscopy (TEM) is sometimes used to analyze bulk materials for
asbestos, but it should only be used as a backup method to PLM. (It is too
precise and may miss asbestos in a product.) TEM is sometimes used because
the extremely narrow fibers found in nonfriable materials like floor tile may be
missed by PLM, if the PLM analysis is not carefully done. For example, many
consultants will not accept a PLM negative result for nine-inch floor tile, and
have the tile reanalyzed by TEM before feeling comfortable telling the client the
tile does not contain asbestos. Scanning Electron Microscopy (SEM) is also
sometimes used for research purposes but is not commonly used for inspection
purposes.
