In-depth survey report: control technology for brake-drum service operations at Ohio Department of Transportation, Maintenance Facility, Lebanon, Ohio
A study of possible asbestos exposure was undertaken at an Ohio Department of Transportation regional headquarters, where repairs and maintenance procedures are conducted for cars, trucks, and specialized equipment. Personal air samples were collected in duplicate on cellulose-ester membrane filters for the duration of a single brake job, or two hours, whichever was longer. Area air-samples were also collected. Personal air sample results for brake mechanics indicate that asbestos concentrations averaged less than 0.004 fibers/cm/sup 3/, with no samples above this level. Mechanics' exposure was well below the NIOSH recommended exposure limit of 0.1 fibers/cc. The authors conclude that use of a vacuum enclosure unit resulted in very low asbestos exposures and that the unit appeared to be an effective device for dust control. A follow-up evaluation is recommended during cold weather with closed doors.
