Are other microscope methods used for asbestos analysis? - CORRECT ANSWER:
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.
Asbestos recordkeeping must keep track of what three basic types of data? -
CORRECT ANSWER: Three 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. - CORRECT ANSWER:
It 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!) 1 / 4
Can a contractor cease personal air sampling for class 1 and 2 work ? - CORRECT
ANSWER: no
Can altering fire proofing in buildings affect insurance and fire proofing of buildings ? -
CORRECT ANSWER: YES, adding encapsulant or removing fire proofing can greatly
reduce the flame retardant nature of fire proofing.
Claims madre insurance vs occurance insurance ? - CORRECT ANSWER: Claims
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 - CORRECT ANSWER: SIZE: that cannot fit into
- 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 - CORRECT ANSWER: a 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 - CORRECT ANSWER: Designed 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 - CORRECT ANSWER: Designed to regulate
custodial work around nonfriable materials. thus its designed for workers who contact but do not disturb asbestos!
Define extent - CORRECT ANSWER: means 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. - CORRECT ANSWER: Friable asbestos will crumble , pulverize or otherwise release dust by applying hand pressure.
Define Severity - CORRECT ANSWER: means 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. - CORRECT ANSWER: Written 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.) 2 / 4
Describe the implications of simply following regulations versus maintaining state of the art practices - CORRECT ANSWER: liability may be based on state of the art practices.
Do you need to resample materials that were already sampled before by a non accredited individual ? - CORRECT ANSWER: Not if an accredited inspector signs and dates a statement that declares the previous samples were sampled within compliance of AHERA
Each time you put on a respirator, what should you do to insure it provides adequate
protection? - CORRECT ANSWER: Insure that the respirator has an appropriate PF
and inspect for tears, missing valves, etc. Do positive and negative pressure face seal checks. (Previously known as "fit-checks.")
Electrical Drawing ? - CORRECT ANSWER: floor plan based power and lighting plans
Floor tile is used throughout a building. How do you determine the number of homogeneous sampling materials? - CORRECT ANSWER: Is it all the same size, color, pattern? If not, how many different types are there? Have there been renovations that might include new flooring? (The color of floor tile indicates a separately manufactured material. Most inspectors use "color" as part of the homogenous material decision- making process only if the color is added during the manufacturing process, not simply painted on. For example, plaster with the same texture that was thought to have been applied during the same construction period would be homogenous regardless of the color of the paint applied to its surface.)
How do you decide whether a material is assessed as potential damage or potential
significant damage? - CORRECT ANSWER: Is the material already damaged? (In
general, potential significant damage is used for materials that are already damaged). Is the expected damage going to be significant or minor? Is there a change in building use that will create a potential for damage? Is there continuing major disturbance?
How do you decide whether damaged material should be assessed as "damaged" or "significantly damaged?" - CORRECT ANSWER: How extensive is it? (Is it over 10% distributed or 25% localized?) How severe is the damage? (Is it superficial, deep, major?) Is the damage extensive and severe? Is this the worst damage in the building?Do you want to insure management planner grasps severity? Are other factors involved such as heavy occupant use, etc?

CORRECT ANSWER: 3 , 2 , 5 , 4 , 3
how many samples 800 sq .ft . of Misc? - CORRECT ANSWER: sufficient to determine

how many samples for 38 LF of TSI ? - CORRECT ANSWER: 3
how many samples for 4 LF TSI ? - CORRECT ANSWER: 3
how many samples for 4- feet of patched TSI ? - CORRECT ANSWER: 1
how many samples of surfacing <1000 sq. ft. ? - CORRECT ANSWER: 3
how many samples of surfacing 3000 sq. ft. ? - CORRECT ANSWER: 5

identify the most likely parties to a legal action against a contractor - CORRECT
ANSWER: building owners, building occupants, other 3rd parties
In brief, why are these records kept? - CORRECT ANSWER: Various regulations
mandate records be kept. Legal liability protection depends on written records. Required notifications depend on sharing written records. Written records allow continuity during personnel changes.
Is there a safe level of asbestos exposure ? - CORRECT ANSWER: no
List three building materials / locations where ACM is likely to be found - CORRECT ANSWER: fire doors, fume hoods, felt under roofs or siding, amosite sheeting, kiln bricks and cement, lab equipment, fire safety and equipment, auditorium curtains, gaskets, vibration joints, etc.
Management plans must describe exactly where in a building ACM materials are located. What are some methods commonly used in plans to denote material locations?
- CORRECT ANSWER: Use drawings, blueprints, diagrams etc. or write description of
exact location.
Mechanical drawing ? - CORRECT ANSWER: HVAC systems
