Asbestos Building Inspector |latest questions and answers 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 re
