Picase note that while PLM analysis is commonly <br /> perfbrmcd on non-friable and fine grained materials such as floor tiles and dust,Ole EPA method recognizes that <br /> PLM is subject to limitations. In Ihcse situations,accurate results may only be obtainable through the use of more <br /> sophisticated and accurate techniques such as transmission electron microscopy(TEM)or X-ray diffraction <br /> (XRD), <br /> Prior to analysis, samples are logged-in and all data pertinent to the sample recorded. The samples are checked for <br /> damage or disruption of any chain-ofcustody seals. A unique laboratory ID number is assigned to each sample. <br /> A hard copy log-in sheet containing all pertinent information concerning the sample is generated. This and all <br /> other relevant paper work are kept with the sample throughout the analytical procedures to assure proper analysis. <br /> Each sample is opened in a class 100 HEPA negative air hood. A representative sampling of the material is <br /> selected and placed onto a glass microscope slide containing a drop of refractive index oil. The glass slide is <br /> phced under a polarizing light microscope where standard mineralogical techniques are used to analyze and <br /> quantify the various materials present, including asbestos. The data is then compiled into standard report format <br /> and subjected to a thorough quality assurance check before the information is released to the client. <br /> Sincerely Yours, <br /> ' I <br /> Lab Manager , <br /> ASBESTOS TEM LABORATORIES, INC. <br /> ---These results relate only to the samples tested and must not be reproduced,except in full,with the approval of <br /> the laboratory, This report must not be used to claim product endorsement by NVLAP or any other agency of the <br /> U.S. Government,--- <br /> 1016 CIUX1 STRGIir .
