• 1.0 PURPOSE OF SURVEY A pre-demolition hazardous material inspection is intended to investigate a structure for potential ACM, sample and provide accurate results to the customer in accordance with 40 CFR 763.86,the EPA regulations for Asbestos Hazard Emergency Response Act(AHERA). Sample test results will be displayed in the survey. Depending on the material sampled,there may be multiple layers within each sample.These layers you will find broken out within each sample on the results report. Each layer of the sample is prepared onto individual slides to be analyzed to provide the most accurate result. 1.1 DEFINITION OF ASBESTOS Class 1: The most potentially hazardous class of asbestos jobs. This work involves the removal of asbestos-containing thermal system insulation and sprayed-orn or troweled-on surfacing materials. Employers must presume that thermal system insulation and surfacing material found in pre-1981 construction is ACM. That presumption, however, is rebuttable. If you believe that the surfacing material or thermal system insulation is not ACM, the OSHA standard specifies the means that you must use to rebut that presumption. Thermal system insulation includes ACM applied to pipes, boilers, tanks, ducts, or other structural components to prevent heat loss or gain.Surfacing materials include decorative plaster on ceilings and walls;acoustical materials on decking, walls, and ceilings;and fireproofing on structural members. Class II: This work includes the removal of other types of ACM that are not thermal system insulation such as insulation such as resilient flooring and roofing materials. Examples of Class II work include removal of asbestos-containing floor or ceiling tiles,siding, roofing, or transite panels. Class Ill: This asbestos work includes repair and maintenance operations where ACM or presumed ACM presumed ACM(PACM)are disturbed. Class IV: This work includes custodial activities where employees clean up asbestos-containing waste and containing waste and debris produced by construction, maintenance, or repair activities. This work involves cleaning dust-contaminated surfaces, vacuuming contaminated carpets, mopping floors, and cleaning up ACM or PACM from thermal system insulation or surfacing material. (Asbestos Standard for the Construction Industry, OSHA 3096 2002(Revised)) **Highlighted asbestos class work are what applies to the removal of the materials found to contain ACM in this survey. If no class is highlighted, no asbestos was detected in this survey. Friability: Friable ACM is any material containing more than one percent asbestos(as determined by Polarized Light Microscopy)that,when dry, may be crumbled, pulverized, or reduced to powder by hand pressure. Non- friable ACM is any material containing more than one percent asbestos(as determined by Polarized Light Microscopy) that,when dry, cannot be crumbled, pulverized, or reduced to powder by hand pressure. Under the Asbestos NESHAP, non-friable ACM is divided into two categories. Category I non-friable ACM are asbestos- containing resilient floor coverings(commonly known as vinyl asbestos tile (VAT)), asphalt roofing products, packaging and gaskets.These materials rarely become friable.All other non-friable ACM are considered category II non-friable ACM.
