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 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 - ANSsufficient 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: TSI - ANS-TSI in general 3. -Less than 6 ft. of patched. 1 - Elbows, Cementitous material sufficient to determine 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.) 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? - ANSinspection 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 What agency does not use the term friable ? why? - ANSOSHA - because tools that are used by workers can easily make non friable materials friable. what are the 3 categories of materials that an inspector must look for when conduction a NESHAP building inspection ? - ANSFriable Materials , Category 1 non friable, and Category 2 Non Friable What are the 3 major illnesses related to asbestos exposures ? - ANSAsbestosis, Lung Cancer, Mesothelioma. What are the 7 major components of the AHERA law ? Whom do they apply ? - ANSinspection and reinspection requirements, sampling and inspection procedures, lab approval process, accredited and non accredited training programs, clearance air testing, management plan requirements, notification requirements. What are the basic differences between negative pressure air purifying, PAPR, and supplied air respirators? - ANSNegative 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 are the basic fit-test methods? - ANSQualitative Fit-Test: yes/no test --standard lists irritant smoke, banana oil, saccharin, and BitrexTM . (Irritant smoke is no longer recommended; consider using BitrexTM , a taste aversion agent.) Quantitative Fit-Test: quantifies effectiveness--uses room air dust for Portacount or a generated aerosol (sometimes known as DOP) for other equipment. What are the four classes of work defined by Cal OSHA 29 CFR 1926.1101 - ANSClass 1 , Class 2 , Class 3, and Class 4 What are the major differences between CFR 1529 and 29 CFR 1926.1101 - ANS1529 requires written report of use, registration for over 100 sq. feet, notification for temporary worke sites, consultant / technician licensing and Carcinogen report of use requirements found in 8 CCR 5203. What are the things a AHERA accredited inspector must do in an AHERA inspection ? - ANSvisually 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 are the three common insurance exclusions - ANSpollution, water damage, employees of others, disposal. What are the three types of asbestos and their associated species? - ANSChrysotile : Serpentine , Amosite and Crocidolites : amphiboles. what are the types of insurance a building owner would want an asbestos contractor to possess before being allowed to work in the building ? - ANSworkers compensation, general liability, and asbestos liability insurance. What asbestos related disease normally appears only after long, large, occupational exposure to asbestos ? - ANSAsbestosis what asbestos related disease primarily affects those exposed to asbestos who smoke cigarettes? - ANSlung cancer - increases chances over 50 times. What does AHERA require be included in a management plan? - ANSdate 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 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.) What does the AHERA rule require regarding recordkeeping? (see section 763.94). - ANSa. Records maintained at central location and stored for 3 years past next reinspection (done every three years). b. Detailed record of any actions taken including: description of activity, location, methods, rational, dates, (contractor or disposal 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 What factor most limits the degree of protection provided by a respirator? - ANSThe fit of the face piece on the individual's face most determines the effectiveness of the respirator. Generally the more surface area covered, the better the fit. That is why a full- face respirator offers more protection than a half-face respirator. Remember that you can't wear a tight-fitting respirator if you have a beard. What is "point counting?" - ANSPoint 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 being below 1%. The point- counting technique might show that there actually is more than 1% when an initial "trace" result is point counted.) What is a Category 1 non friable, and Category 2 Non Friable Via NESHAP? - ANSnon friable materials including packing, gaskets, resilient floor covering, and asphalt roofing products, ACM products not in category 1 (usually cementitous products) What is a damaged material by AHERA ? - ANSLoss of cohesion or adhesion properties What is a Friable material via NESHAP? - ANS>1% asbestos that can be crumbled into dust by hand pressure. What is a latency period ? What is the latency period for asbestos related illnesses ? - ANSthe time between exposure and symptoms / sign of illness. 10-40 years. What is a significantly damaged material by AHERA ? - ANSDamaged ACBM where the damage is extensive AND severe. What is a Underwriters (UL) rating indicate - ANSprovides rating of fire resistance in hours for a particular building assembly. What is Accessible by AHERA ? - ANSMaterial is subject to disturbance by building occupants or custodial or maintenance personnel in the course of their normal activities. what is Adhesion - ANSmeans adhered to the substrate or insulated component What should be performed at an asbestos medical surveillance exam ? - ANSOccupational History Exam, Chest X ray, Pulmonary Function Test, stool sample What type of microscope is used to analyze bulk asbestos samples? When might you use another method? - ANSBulk 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 types of work are included in OSHA's 29 CFR 1926.1101 - ANSdemolition, salvage, removal, encapsulation of ACM, construction, alteration of ACM or construction, alteration, repair, maintenance, renovation, or clean up of debris. what would 1 pipe coming from a piece of building equipment be ? - ANSan expansion tank what would 2 or 4 pipes or 2 or more ducts coming from a piece of building equipment be ? - ANSair handling unit what would 2 pipes coming from a piece of building equipment be ? - ANSstorage tank what would 3 pipes coming from a piece of building equipment be ? - ANSboiler heater what would 4 pipes and 2 tanks coming from a piece of building equipment be ? - ANSchiller what would 4 pipes coming from a piece of building equipment be ? - ANSheat exchanger When and why would protective clothing be required when doing an asbestos inspection? - ANSProtective 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. When are asbestos medical surveillance physical exams required ? - ANS- Before doing the work (pre employment, pre placement) - Annually - Upon termination (Cal OSHA requirement) When can a contractor cease air monitoring ? - ANSa negative exposure assessment can be achieved via air sampling to document no exposure via PEL and Exursions for class 3 and 4 work. When is a FED EPA notification required ? - ANSwhenever more than 160 square feet, 250 linear feet, or one cubic meter will be disturbed as part of a renovation When is a NESHAP notification required? - ANSRequired for all demolition even if no ACM. When is unaccredited in house training ok ? - ANSMaintenance or custodial working in areas where friable ACM is present (2 hour awareness course) , Maintenance personnel disturbing small amounts of asbestos (2 hours awareness + 14 for sixteen hours operations and maintenance training). where in a building would asbestos fire proofing most likely be ? - ANSon exposed steel beams and decking most often found in multistory buildings. Which respirators must be fit-tested according to the asbestos standard and by which fit-test method (qualitative or quantitative)? - ANSAll tight-fitting respirators must be fit- tested at the initial fitting and at least annually thereafter. A full-face air-purifying mask has an assigned PF of 10 if it is qualitatively tested and a PF of 50 only if it is quantitatively tested. Air purifying half-face masks may be fit-tested using either method but will always have a maximum assigned PF of 10 times the PEL. Test PAPRs and positive pressure respirators in the negative pressure mode. Use either fit-test method. They maintain their OSHA assigned PF regardless of which method you use. 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? - ANSNIOSH 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 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! who must participate in a medical surveillance program - ANS-Employees who conduct Class I, Class II, and Class III work for more than thirty days. -Employees who are exposed over the PEL for thirty or more days in a year. Why are computers useful in asbestos recordkeeping? - ANSVolume 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. Why does cigarette smoking increase chances of getting an asbestos related illness ? - ANSParalyzes Cillia in lung. Why is a fire rating of a building important to an inspector ? - ANSfire rating may indicate the use of suspect ACM. Why is systems approach to building inspection favorable over a component system? - ANSknowing the types of systems in a building will allow you to anticipate where components are located even when they are hidden. a component approach is limited to counting what you seen in an individual space. Why was asbestos added to construction materials ? - ANSIt provided: insulation properties, strength and durability from weathering, made spray on products easier to apply, and does not conduct electricity.
