PLM POINT COUNT ANALYSIS REPORT PERFORMED BY EPA 6001R-93/116 METHOD.

Sample Sample Appearance Asbestos Non-Asbestos ID Description % T % Fibrous % NonFibrous A2541 Dust Sample Brown 0:J1% Chrysotile 30% Cellulose 29.49% Other on Roof Fibrous 40% Min. Wool Homogeneous PLM / NOB

Comments: For all obviously heterogeneous samples easily separated into subsamples, and for layered samples, each component is analyzed separately. . Also "# of Layers" refers to number of separable subsamples. * NY samples analyzed by ELAP 198.1 method. * Disclaimer: Polarized Light Microscopy is not reliable in detecting asbestos in floor coverings and similar non-friable organically bound materials (NOBs). Results <1% are inconclusive and quantitative TEM is currently the only method which can be used to determine if this material can be considered or treated as nom-asbestos containing.
