AHERA mandates the number of samples that must be taken randomly to prove a
material is not ACM. How many samples must you take for: Surfacing Material - ANS-
Less than 1000 sq. ft. 3 Recommend 9. -Between 1000 and 5000 sq. ft. 5 Recommend
9.
-Greater than 5000 sq. ft. 7 Recommend 9

ANS-TSI in general 3.

Are other microscope methods used for asbestos analysis? - ANSTransmission
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.
Asbestos recordkeeping must keep track of what three basic types of data? - ANSThree
basic types include data on the physical condition of ACM materials, response actions
taken, and various characteristics of personnel in the asbestos program (training,
accreditation, medical surveillance, etc.).
Briefly define what is meant by a homogeneous sampling area. - ANSIt is an area of
material that is uniform in color and texture and you believe is all the same. (Besides
color and texture, most inspectors also add to the definition "and believed to be installed
at the same time or during the same construction period.") It is easier to think in terms of
a homogeneous sampling material (rather than area). This helps us identify which
materials need to be sampled and how often. The same material may be found in many
, functional spaces. Sprayed acoustic ceiling material may be homogeneous throughout
an entire building (or it may not be!)
Can a contractor cease personal air sampling for class 1 and 2 work ? - ANSno
Can altering fire proofing in buildings affect insurance and fire proofing of buildings ? -
ANSYES, adding encapsulant or removing fire proofing can greatly reduce the flame
retardant nature of fire proofing.
Claims madre insurance vs occurance insurance ? - ANSClaims made = claims made
during policy period, Occurence = insures occurence taking place during the policy
period regardless of when the claim is made.
Define Class 1 via 29 CFR 1926.1101 - ANSSIZE: that cannot fit into 1 glove bag or in
standard 60 - in width glove bag (Large Job).
TYPE of materials: Regulates the removal of TSI / Surfacing / PACM
Define Class 2 via 29 CFR 1926.1101 - ANSa large job where the removal of ACM that
is non friable and is not TSI or surfacing material. no size limit. Determined by TYPE of
material.
Define Class 3 via 29 CFR 1926.1101 - ANSDesigned to regulate work involving small
amounts of asbestos (TSI, surfacing, PACM, or ACM) that is disturbed (will fit into one
glove bag or standard waste container). Determined by SIZE of job.
Define Class 4 via 29 CFR 1926.1101 - ANSDesigned to regulate custodial work around
nonfriable materials. thus its designed for workers who contact but do not disturb
asbestos!
Define extent - ANSmeans whether the damage is localized or distributed over a broad
area. Damage is extensive if localized damage amounts to more than 25% of the
material or damage is distributed over 10% of the material.
Define Friable vs non friable. - ANSFriable asbestos will crumble , pulverize or
otherwise release dust by applying hand pressure.
Define Severity - ANSmeans whether the damage is superficial or deep. Superficial
might include water stains, flaking, blistering, abrasions or scratches. Deep might
include major separation of layers gouges, water damage, punctures, tears, etc.
Describe at least four components of a respiratory protection program. - ANSWritten
procedures, respirator selection criteria, medical surveillance, fit-testing (quantitative
and qualitative), training, inspection, maintenance, storage, cleaning, etc. (While there is
no requirement for a written "test," many employers feel it appropriate to make workers
demonstrate they have learned the information.)
