CSST Exam building inspection Exam Question & Answers 2024 Do you need to resample materials that were already sampled before by a non accredited individual ? - Correct Answers ✅Not if an accredited inspector signs and dates a statement that declares the previous samples were sampled within compliance of AHERA What are the things a AHERA accredited inspector must do in an AHERA inspection ? - Correct Answers ✅visually inspect every area , touch all suspect acm materials to determine friability, identify type of product (TSI , surfacing, misc), sample each suspect material or assume its ACM , document, determine condition. what is the difference between an inspection and an assessment - Correct Answers ✅inspection involves touching materials, identifying suspected materials, and taking samples assessment involves assessing the damange (if any) of the material and placing it in a specific category what is Adhesion - Correct Answers ✅means adhered to the substrate or insulated component what is Cohesion - Correct Answers ✅means material with structural integrity Define extent - Correct Answers ✅means whether the damage is localized or distributed over a broad area. Damage is extensive if CSST Exam building inspection Exam Question & Answers 2024 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? How do you decide whether a material is assessed as potential damage or potential significant damage? - Correct Answers ✅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? The fifth floor of an office building has 10 identical offices (5 on each side of a common hallway) used by clerical 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? - Correct Answers ✅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 - CSST Exam building inspection Exam Question & Answers 2024 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. - Correct Answers ✅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. - Correct Answers ✅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? - Correct Answers ✅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? CSST Exam building inspection Exam Question & Answers 2024 (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.) 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 - Correct Answers ✅-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 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: TSI - Correct Answers ✅-TSI in general 3. -Less than 6 ft. of patched. 1 - Elbows, Cementitous material sufficient to determine 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 - Correct Answers ✅sufficient to determine CSST Exam building inspection Exam Question & Answers 2024 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. When and why would protective clothing be required when doing an asbestos inspection? - Correct Answers ✅Protective clothing will keep bulk asbestos fibers off the inspector's skin and/or clothing. Therefore protective clothing helps protect the inspector and helps him/her keep from exposing family members or friends to asbestos fibers. Normal bulk sampling procedures should not create a fiber release requiring protective clothing. Generally, inspectors should have protective clothing available should they need to go into a heavily contaminated area where they are likely to create airborne fibers. For example, protective clothing may be appropriate in contaminated crawl spaces, tunnels, and even air plenums. Who decides whether a respirator is OK for asbestos? What is a P-100 or HEPA cartridge? Are there restrictions on who can wear a respirator? - Correct Answers ✅NIOSH must approve respirators before they can be worn for asbestos (or other contaminant protection.) NIOSH categorizes respirator cartridges based on their ability to filter and their resistance to damage by oil. For asbestos, you must wear a 100 series respirator. These filters are also more commonly known as High Efficiency Particulate Air (HEPA) filters. The P-100 (oil proof) series CSST Exam building inspection Exam Question & Answers 2024 respirator is likely to have a magenta color similar to historical HEPA respirator filters. The other 100 series (N and R) may have different colored filters. You cannot exchange parts (filters, seals, connections, etc.) from one manufacturer's model and use those parts with another manufacturer's model. Not everyone can wear a respirator. First, everyone who wears a respirator (any type of respirator) for compliance with OSHA must have a medical approval. (This is usually a component of medical surveillance but it can be a separate issue.) Various medical issues such as heart, lung, or skin problems may keep an individual from wearing a respirator. (Other issues, such as claustrophobia-- fear of feeling confined--may also preclude respirators.) Also, remember, tight-fitting respirators cannot be worn by anyone who has facial hair (beards, long mustaches/side burns, etc.) or glasses that might break the respirator seal! What are the basic differences between negative pressure air purifying, PAPR, and supplied air respirators? - Correct Answers ✅Negative pressure air purifying: worker breathes room air filtered through HEPA filter. PAPR: room air is filtered through HEPA filter and small fan blows the air into the facepiece. Air Supplied: fresh air from outside the contaminated area is pumped into the workers facepiece through a hose. What is meant by "Protection Factor?" Name the Protection Factor (PF) for each type of respirator. (Inspectors are only tested on half-face air purifying. Planners are tested on all types.) - Correct Answers ✅Protection factor (PF) is a numerical rating of respiratory CSST Exam building inspection Exam Question & Answers 2024 effectiveness; it is the ratio of fibers in the air outside the respirator to the fibers inside the respirator. (PF=outside concentration divided by inside concentration) what is the PF for a Negative air Half Mask ? - Correct Answers ✅10 what is the PF for a Negative air Full Face ? - Correct Answers ✅50 or 100 if quantitatively fit tested. what is the PF for a PAPR ? - Correct Answers ✅1000 what is the PF for a Air supplied continuous flow and pressure demand? - Correct Answers ✅1000 what is the PF for a pressure demand SCBA ? - Correct Answers ✅10,000 Each time you put on a respirator, what should you do to insure it provides adequate protection? - Correct Answers ✅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.") CSST Exam building inspection Exam Question & Answers 2024 information if relevant), air sampling results, lab accreditation information, etc. c. Training records d. Periodic surveillance record including dates, personnel, results e. Cleaning record including name, date, methods f. O&M activity record g. Maintenance work regarding ACM h. Fiber release episodes Why are computers useful in asbestos recordkeeping? - Correct Answers ✅Volume of data continues to grow. Computers allow easier updating, access, duplication, sorting by various aspects such as damage category, building, location, etc. Not helpful if all ACBM is immediately removed or if reports include only a small amount of data. What does AHERA require be included in a management plan? - Correct Answers ✅date of inspection (or reinspection), name and accreditation data for individual doing the inspection and those doing any sample collection; some type of written (drawing, blueprint, description) method that describes each building and exact location and approximate amount of ACM, the exact location where samples where collected; sample dates of collection, results, homogeneous areas (and a description of how each area and sample was chosen), sample results, proof of lab accreditation; description of material assessments (and name/accreditation of person doing assessment); recommendations regarding response options; description of CSST Exam building inspection Exam Question & Answers 2024 preventive measures and response options to be taken, a schedule for those activities; a plan for re-inspection activities; statement that only accredited individuals will be used; a plan for operations and maintenance activities; and description of any notification activities. (You must read the exact requirements if you are developing a plan for an AHERA school.) 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 Answers ✅Use drawings, blueprints, diagrams etc. or write description of exact location.
