• Description:
  An evaluation was undertaken of various control measures used to help cut down the exposure of automobile mechanics to asbestos (1332214) fibers during the servicing of brakes. Five facilities employing five methods to control asbestos exposure were part of the initial evaluation. These control methods included the use of two commercial enclosure devices with ventilation provided by a HEPA filter equipped vacuum, a HEPA filter equipped vacuum alone, a brush with recirculating cleaning solution, and cleaning solvents in aerosol cans. During the servicing of brakes on automobiles, pickup trucks, vans, and vehicles with a four wheel rear axle, measurements were taken using traditional air sampling methods, incorporating phase contract microscopy and transmission electron microscopy and real time analysis of brake dust exposure. All the devices tested, in combination with the work practices used, controlled the exposure of the mechanic to asbestos fibers during brake servicing to less than the recommended limits. The exposures reported in this evaluation were much lower than those reported in the literature for brake service operations involving the use of compressed air and brush cleaning. Recommendations were made for improved work practices and modifications to the control systems. [Description provided by NIOSH]
