4.15 Building MB 785 (Sheet Metal and Battery Shop)

Building MB 785 is a large building containing a variety of aircraft maintenance shops. The building was constructed by the U.S. military in 1966. Photograph available here.

A total of 54 samples were collected from 7 different material types in Building 785 during the inspection visit of 5 and 6 November 2009. Sampled materials included gypsum board and finishing compound, vinyl wall covering, vinyl cove molding and mastic, vinyl floor tiles and mastics, ceiling tiles, thermal system insulation, and duct insulation mastic. Table MB 785-1 provides a listing of the samples with their analytical results. Figures MB 785A-loc and MB 785B-loc show a floor plan of the building showing the sample locations.

NAD=No asbestos detected

Of the sampled materials in Building MB 785, the following contained asbestos:

• 12” x 12” floor tile, unknown color, and black mastic found in a maintenance space (Room 12). NESHAPS Classification: Category I Non-friable ACM assessed as being in damaged condition. The floor tile had been overlain with carpet and carpet mastic; it contains 2% chrysotile asbestos and the mastic contains 5% chrysotile asbestos.

Photograph available here.

• Thermal System Insulation on piping in various locations throughout MB 785; the pipe insulation is fiberglass lagging with hard, troweled-on pipe-joint insulation. NESHAPS Classification: Friable RACM, removal required prior to repair, renovation or demolition.

The pipe joint mud contains chrysotile (15%-65%) asbestos; it was assessed as being in damaged condition and it lacks protective covering. The pipe insulation is normally accessible only to maintenance personnel, as it is either above drop ceiling systems or suspended high above open-ceiling shops. This material should be labeled, maintained and monitored for deterioration. Photograph available here.

• Black Duct Insulation Mastic found on duct insulation above Rooms 4, 13, 15, and 16.

NESHAPS Classification: Category I Non-friable ACM found in good condition. This material contains 7% to 8% Chrysotile asbestos but is relatively inaccessible to building occupants. HVAC maintenance personnel should be cautioned to avoid any work practices which would sand, grind, abrade, or pulverize the mastic. Photograph available here.
