Attachment 4 - Bldg 33 Abestos Survey Report.pdf

This document is an Asbestos Survey Report for Building 33 at the Department of Veterans Affairs Seattle Division, prepared by EHS International, Inc. on September 15, 2010. The report details a comprehensive asbestos materials reinspection conducted on July 21, 2010, with the primary objectives of identifying, quantifying, and determining the condition of potential asbestos-containing materials (ACM) in the facility.

The survey involved collecting 20 bulk samples of suspect ACM materials throughout the building, which is a radiation therapy center with a concrete foundation, marblecrete exterior wall, and various interior finishes including inoperable windows, carpet, vinyl composite tile, and suspended acoustical ceiling tiles. Laboratory analysis using polarized light microscopy found no asbestos-containing materials in any of the samples. The report emphasizes that any suspect materials should only be handled by properly trained personnel, and that demolition or renovation activities may potentially expose concealed ACM materials. The inspection was limited by tenant restrictions, and only accessible areas were examined.
