Project No. 094-23024 <br /> Page No. 3 <br /> 4.2 Laboratory Analytical Methods <br /> 4.2.1 Laboratory Analysis: Asbestos <br /> All asbestos samples were delivered to Seattle Asbestos Testing Labs under strict chain-of-custody. <br /> Seattle Asbestos Testing Labs is accredited by the National Institute of Standards and Technology(MIST) <br /> under the National Volunteer Laboratory Accreditation Program (NVLAP) program for bulk asbestos <br /> fiber analysis;NVLAP Lab Code 200768-0. <br /> In accordance with 40 CFR Chapter 1 (1-1-87 edition)Part 763, Subpart F,Appendix A,asbestos samples <br /> were analyzed at Seattle Asbestos Testing Labs using polarized light microscopy (PLM) with dispersion <br /> staining. If samples are not homogeneous, then sub-samples of the components are analyzed separately. <br /> Findings for samples containing more than one separable layer of materials are reported for each layer. <br /> The asbestos concentration in the sample is determined by visual estimation. <br /> 4.2.2 Laboratory Analysis: Lead <br /> Samples were analyzed for the presence of inorganic lead at Freidman & Bruya Labs using atomic <br /> absorption spectroscopy (AAS) in accordance with EPA SW 846, method 200.8. This method reports <br /> results in milligrams per kilogram (mg/kg), or its equivalent,parts per million(ppm). <br /> Freidman&Bruya Laboratory, Inc. is a Washington Department of Ecology-accredited laboratory for the <br /> testing of lead in paint;Laboratory ID#C578. <br /> 5.0 RESULTS OF INVESTIGATION <br /> As stated previously, ten (10) samples of suspected ACMs and two (2) samples of suspected LBP were <br /> collected from the structure. Analytical laboratory results and field observations of the materials sampled <br /> have been summarized on Table 5.1 and 5.2, respectively. Information presented within these tables <br /> include the sample number, the sample description, the location where the sample was obtained, the <br /> asbestos/lead content, the volume of ACMs/LBP identified (typically expressed in square feet), the <br /> condition of the material sampled, and a listing of locations where similar (homogenous) ACMs/LBPs <br /> were also noted (although not necessarily sampled in these areas). In addition, footnotes have been <br /> provided to convey pertinent information regarding the specific sample or homogenous material. <br /> Asbestos <br /> None of the samples collected from the on-site structure contained one percent or more of asbestos. <br /> KRAZAN&ASSOCIATES,INC. <br /> With Offices Serving the Western United States 094-23024Hazmat Surrey <br />
