Asbestos Building Inspector Exam Fall 2023 with complete solution

Asbestos Building Inspector Exam Fall 2023 with complete solution Characteristics of asbestos mineral -Naturally occurring -Thermal properties (heat stability, thermal, electrical and acoustic insulation) -Resistance to chemical, thermal and biological degradation -Absorption capacity - Tensile strength What type of asbestos is the fibrous serpentine Chrysotile (white asbestos)- Most common type found in schools Two categories of asbestos minerals and their characteristics 1. Serpentine- curly, wavy, sheet-like 2. Amphibole- rod-like, straight, chain-like Name the 5 amphiboles Amosite Tremolite Actinolite Crocidolite Anthopyllite Asbestos Applications -Roofing -Thermal and electrical insulation -Cement pipe and sheets -Flooring -Gaskets -Friction materials (brake pads/shoes) -Coatings and compounds - Plastics, textiles, mastics, thread, fibre jointing and millboard Categories of ACBM -Surfacing Materials -Thermal System Insulation -Miscellaneous Materials Asbestosis "white lung" a disease that causes scars on the lungs. Not a cancer. Marker disease. Only caused by asbestos. Friable ACM ACM that can be crumbled, pulverized, or reduced to powder by hand pressure. Example: sprayed-on ceiling insulation. Friable ACM cannot be made non-friable Non-friable ACM ACM that cannot be pulverized under hand pressure. (If sawed, drilled, stripped, or sanded the material may become friable.) Example: vinyl-asbestos floor tile. - Category I: non-friable includes roofing, flooring, packings, and gaskets. - Category II: non-friable includes all other non-friable asbestos materials AHERA The Asbestos Hazard Emergency Response Act. 40 CFR Part 763, Subpart E. Promulgated in 1986, requires that all schools, grades K-12 (non-profit), be inspected for the presence of ACBM (asbestos-containing building material). ACBM Asbestos Containing Building Material ASHARA The Asbestos School Hazard Abatement Reauthorization Act. Promulgated in 1990, effective Nov. 1992, requires that any asbestos inspection conducted in a public or commercial building be performed by an accredited Building Inspector. Extended the accreditation requirements to cover asbestos workers, supervisors, and inspectors in public and commercial buildings. Increased minimum number or training hours for workers and supervisors. Building Inspector Responsibilities (AHERA & ASHARA) 1. Determining whether ACBM is present in a building 2. Assessing the physical characteristics of the ACBM within the building. A building inspection involves: 1. Investigation of records for the identification of ACBM 2. A physical and visual inspection of the building for suspect materials 3. Sampling and analyzing suspect materials to test for asbestos 4. Assessing the condition and location of the ACBM and other characteristics of the building Management Planner Role Uses info from the building inspection to estimate the degree of current or potential hazard posed by the ACM and develop a plan for managing the ACM. After ACM is confirmed, create O&M plan, stays in effect until ACM is removed. EPA Worker Protection Rule Extends the OSHA standards to state and local employees who perform asbestos work and who are not covered by the OSHA Asbestos Standards, or by a state OSHA plan. Three areas of potential liability for a building inspector: Criminal, Regulatory and Civil Common "tort" theories negligence, fraud, misrepresentation, assault and battery How AHERA affects your work/changed things: 1. Defines ACM as being more than 1%. 2. Lays out 5 control methods: operations and maintenance, enclosure, encapsulation, repair, and removal. 3. Describes clearance air sampling at end of job with aggressive air sampling and a TEM. 4. Regulates training classes like this one and requires this training for all workers working with asbestos (excludes single-family homes) What options does a school have to manage and control ACM and what laid them out? O&M, enclosure, encapsulation, repair, and removal. AHERA created. TEM Transmission Electron Microscope/Microscopy. May be used to detect smaller fibers of asbestos. ASHAA Asbestos School Hazard Abatement Act. 1984, Directed EPA to help schools carry out their asbestos hazard responsibilities. MAP Model Accreditation Plan. From EPA, said now everyone doing things with asbestos must adhere, not just schools. (40 CFR 763 Subpart E Appendix C) mandates safety training for those who do asbestos removal work, and implements the additional training requirements mandated by Congress in the Asbestos School Hazard Reauthorization Act of 1990 as well as its requirements for training of asbestos workers in public and commercial buildings. Public and commercial buildings: All buildings other than school buildings and apartment buildings with greater than 10 units. NESHAP National Emissions Standard for Hazardous Air Pollutants. 40 CFR Part 61, Subpart M How NESHAP affects your work/changes things: 1. Defines any job at least 160 sqft , 260 lf, or 35 cf as a large job 2. Asbestos must be wet before taken down and sealed in airtight container 3. Employer must notify EPA of the job 10 working days before begins (notify even if no asbestos for a demo) 4. Waste bags must be labeled with the location of the job and name of waste generator, be 6 mil thick, say "Danger contains asbestos fibers avoid creating dust cancer and lung disease hazard" 4. Buildings musts be inspected for asbestos prior to demo or reno. 5. Requires there be no visible emissions to the outside air during removal Buildings covered under NESHAP (and exclusions) Excluded: private homes and apartment buildings with 4 or less units (Except these are covered still in SoCal under SCAQMD) Included: Institutional Buildings (hospitals, schools), commercial buildings (offices, apartment buildings), industrial buildings (warehouses, factories). Removal before reno or demo rule & exceptions All RACM must be removed before demo or reno of a building if the amount of ACM is greater than 160 sqft, 260 lf, or 35 cf Exception: Does not need to be removed if it's Cat I nonfriable ACM (packing, gaskets, asphalt roofing, vinyl - have flexibility and won't become DUST if hit), on a component packed in concrete, not accessible for testing or not discovered before demo, Cat II nonfriable (that are unlikely to become crumbled, or reduced to powder during demo) RACM Regulated asbestos containing material. Friable ACMs (like popcorn ceiling) Category I non-friable materials Category II non-friable materials OSHA Construction Industry Asbestos Standard
