The sample was delivered to MVA Scientific Consultants from Charlie Ay on 21 June 2011 via FedEx. The following information is provided on the tag: "Square D Company; Cleveland, Ohio; Magnetic Contactor; Class: 7004, Type: S0307A, Ser: 3, Volts: 230, Cycles: DC, Amps: 8, NEMA Size: 3, FE87". The contactor was assigned the MVA sample number W0941. MVA Scientific Consultants was asked to analyze the contactor for asbestos content. Three components of the unit were analyzed separately and assigned sample number modifiers as listed in Table 1. The analyses were done in our laboratory during the period of 23 June to 1 July 2011. Methods Each component was initially examined under an Olympus SZ-40 stereomicroscope at magnifications from 7X to 40X. Portions of the particulate found in each component were mounted in Cargille refractive index liquids for analysis by polarized light microscopy (PLM) using an Olympus BH-2 polarized light microscope (PLM) with a magnification range from 100X to 1,000X. The PLM analysis followed the analytical procedures recommended by the U.S. Environmental Protection Agency [1]. The PLM results for asbestos are given in terms of percent by volume. In order to determine whether or not asbestos fibers were readily releasable from the arc chute surface, a finger was applied to the surface of the arc chute and the material transferred to an SEM stub for analysis by scanning electron microscopy (SEM). 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 The PLM analysis is summarized in Table 1. Component W0941A represents a white cement-like material known as an "arc chute." This arc chute was found to contain 20-30% chrysotile asbestos. Components W0941B and W0941C consist primarily of cellulose and a resinous binder. No asbestos was observed in W0941B or W0941C. Photographs of the contactor as received are shown in Figures 1 and 2. A PLM image of chrysotile fibers observed during analysis are provided in Figure 3. Asbestos fibers are protruding from the edge of the arc chute (Figure 4). Asbestos fibers were released from the arc chute and transferred onto a finger (Figures 5 and 6). toJA 8895reportSquareD_071811 Page 2 of 7 References 1. U. S.
