Dust samples
Fibrous materials in dust found by Polarized Light Mieroscopy (PLM) Analysis: Polarized
Light Microscopy identifies asbestos fibers by shape arid optical characteristics. Other fibers
such as fabric (synthetics), paper (cellulose) and fiberglass may be identified in the analysis. The
laboratory analyst counts the fibers present to give an estimate of fiber content as a percent.

Asbestos in dust as determined by Transmission Electron Microscope (TEM) Analysis:
TEM analysis was conducted on all dust samples, which showed asbestos content, by PLM as
less than 1%. TEM analysis is very specific, can detect smaller fibers of asbestos and is
sensitive to fewer interferences. This analysis was done to confirm the PLM findings of no
asbestos showt above.
