Asbestos Report for Bldg 112.pdf

This is a Polarized Light Microscopy/Dispersion Staining (PLM/DS) test report prepared by QUEST MicroAnalytics, Inc. for asbestos analysis of bulk materials collected from Building 112, Youth Center at Misawa Air Force Base.

The report documents the testing of 54 bulk material samples submitted on October 16, 2002, by Raymond Eberhardt of Sublett Japan Inc., with analysis completed and reported on November 4, 2002. Testing was conducted using EPA Method 40 CFR Chapter 1, Part 763, Subpart F, Appendix A. The samples included various building materials such as floor tiles with adhesives and mastics, acoustical ceiling panels, gypsum wall board with paint and tape, vinyl sheet flooring, cove base materials, caulking, pipe insulation wraps, duct wrapping, pipe flange gaskets, and carpeting with adhesive, collected from multiple locations throughout the facility including lounges, offices, storage areas, mechanical rooms, and restrooms. Results indicated that the vast majority of samples contained no detectable asbestos. However, three samples contained asbestos: sample 112-23 (Red/White Floor Tile with Gray Mastic from Storage #1) contained 10% chrysotile in the mastic component, sample 112-24 (Green/White Floor Tile with Gray Mastic from Kitchen) contained 10% chrysotile in the mastic, and samples 112-49 and 112-50 (Light Gray Pipe Flange Gaskets from Mechanical Room) each contained 60% chrysotile. The report notes that materials containing greater than 1% asbestos are considered asbestos-containing materials and must be handled accordingly. Lab Director Jennifer D. Jaber approved the findings, with analyst Jennifer Jaber conducting the examination.
