The Ohio Department of Transportation, Maintenance Facility (SIC- 7538), Lebanon, Ohio, was visited as part of a study of asbestos (1332214) control during the maintenance and repair of vehicular brakes. The effectiveness of various control technologies designed to reduce asbestos exposure were evaluated. This garage is responsible for the maintenance of 170 large trucks, 250 pickup trucks, 90 passenger cars, 25 vans, and 25 loaders. Approximately 400 to 500 brake jobs are performed each year. Brakes are serviced using a Clayton brake cleaning unit, which was installed six weeks prior to the study. Before that time, brakes were washed with a brush and the mechanic wore a protective mask; no air pressure was used. The Clayton system was designed to contain and collect asbestos fibers liberated when the brake linings are serviced. Each Clayton system includes a brake enclosure hood and a HEPA filtered dust collector. The author concludes that the Clayton system appears to be a good state of the art device for control of asbestos dust from brake servicing operations, and should be evaluated. The author recommends this facility for an in depth survey.
