Do you need to resample materials that were already sampled before by a non accredited individual? - โ โ Not if an accredited inspector signs and dates a statement that declares the previous samples were sampled within compliance of AHERA
Define Severity - โ โ 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.
what is the difference between periodic and episodic damage? - โ โ Periodic damage is recurring or continuous. For example, periodic damage results from the abrasion of TSI when a worker steps on it daily to read a gauge. Or, it might result from a continual (though sporadic) water leak onto or from TSI covered pipe. Episodic damage is a one-time occurrence, a freak event unlikely to recur. For example, episodic damage results from a pipe or valve bursting, or a plumber disregarding safe work practices, etc.
What is a damaged material by AHERA? - โ โ Loss of cohesion or adhesion properties
What is a significantly damaged material by AHERA? - โ
โ Damaged ACBM where the damage is extensive AND severe.
What is potential damage by AHERA? - โ โ Friable ACBM in an area regularly used by building occupants, including maintenance personnel in the course of their normal activities; there are indications that the material will become damaged, delaminated or deteriorated.
What is potential significant damage by AHERA? - โ โ Damaged friable ACBM in an area regularly used by building occupants, including maintenance personnel in the course of their normal activities; there are indications that the material will become significantly damaged, delaminated or deteriorated, AND the material is subject to continuing major disturbance.
What is Accessible by AHERA? - โ โ Material is subject to disturbance by building occupants or custodial or maintenance personnel in the course of their normal activities.
What is Exposed by AHERA? - โ โ Material that is not concealed from view by any kind of barrier, such as a drop ceiling, a radiator housing, or a metal jacket
and administrative staff. There is a drop ceiling, and an open air-plenum with sprayed fireproofing over the entire floor. Near the end of the hall is an unlocked mechanical/electrical room. Next to it is a closet where custodial supplies are kept. Across the hall are men and women's restrooms. At each end of the hall are stairways with exposed fire proofing on the ceiling and insulated risers. If you were only inspecting this floor, what
functional spaces would you divide it into and why? - โ
โ inspection showed few significant differences). functional space - all 10 offices (similar occupants and functions) functional space - hallway (though could easily be grouped with offices) (similar occupants and function) functional space - mechanical room (limited function and limited occupant access) functional space - custodial closet (limited functions and occupant access) functional space - restrooms functional space - stairways functional space - entire air plenum
Name at least 5 items that an inspector should have on hand when planning to take samples. - โ โ Leakproof sampling containers, spray mister bottle with amended water, drop clothes,
knife/cutter/borer/drill or other sampling tool, caulking, pen and labels, ladder, flashlight, tape, cloths for spill cleanup, HEPA vacuum, camera, respirator, protective clothing
Briefly define what is meant by a homogeneous sampling
area. - โ โ 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!)
Floor tile is used throughout a building. How do you determine the number of homogeneous sampling materials? - โ โ 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
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: Misc materials - โ โ sufficient to determine
how many samples for 4- feet of patched TSI? - โ โ 1
how many samples for 1 pipe elbow? - โ โ sufficient to determine
how many samples for 38 LF of TSI? - โ โ 3
how many samples for 4 LF TSI? - โ โ 3
how many samples of surfacing <1000 sq. ft.? - โ โ 3
how many samples of surfacing 3000 sq. ft.? - โ โ 5
how many samples of surfacing 6000 sq. ft. - โ โ 7
how many samples 800 sq .ft. of Misc? - โ โ sufficient to determine
What type of microscope is used to analyze bulk asbestos samples? When might you use another method? - โ โ Bulk samples must be analyzed by Polarized Light
Microscopy (PLM). However, the extremely narrow fibers found in nonfriable materials such as floor tile or plaster may be missed by PLM. You might want to use TEM as a double check on negative PLM results for products (such as nine-inch floor tiles) where the PLM result is negative. Do not use TEM alone for bulk samples. It should only be used in conjunction with TEM.
What is "point counting?" - โ โ Point counting is the name of a counting technique used to make PLM results more accurate. Simply put, during normal visual PLM analysis, the analyst estimates the percent of asbestos by area under the microscope. This is not a very accurate method at low concentrations of asbestos (say under 5%). With point counting, the analyst determines if asbestos fibers are touching one or more of 400 points marked on the microscope. If they are touching a point, they are counted. If they are not touching a point, they are noted but not counted. This method is thought to be more accurate than the normal visual estimation method at low concentrations. (This is why, for NESHAP analysis, a "trace" or "less than 1%) must be re-analyzed using the point-counting method if you wish to treat it as actually
