Report of Results: MVA9214 Examination of a SQUARE D Enclosed Switch Box Exhibit D (Beach Case) Prepared for: Lipsitz & Ponterio 135 Delaware Avenue, 5th Floor Buffalo, NY 14202-2415 fcRespectfully Submitted by: ( ----- -.........

The SEM analysis was done using a JEOL JSM-6490LV coupled with a Thermo Scientific Noran System SIX x-ray energy dispersive spectrometer (EDS). Results Sample X0479 (SQUARE D Class 6536 electrical control unit labeled 'Exhibit D') contained three suspect pieces that were designated as X0479A, X0479B and X0479C (Figures 1 and 2). The results of the PLM analyses are summarized in Table 1. Subsample X0479A contained 10-20% chrysotile asbestos by PLM (Figure 3). Asbestos fibers were protruding from the surface (Figure 4). According to the FTIR analysis, the resin binder in X0479A is consistent with a polyethylene (Figure 5). No amphibole asbestos fibers were found by TEM in Sample X0476A after acid/base digestion. The analytical sensitivity of the TEM amphibole analysis was 8x10-8%. Asbestos fibers were released from the X0479A material and transferred onto a finger (Figure 6). Subsamples X0479A, X0479B and X0479C appeared to be identical material. X0479B and X0479C were not analyzed. References 1. U. S.
