National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Industrial Hygiene Assessment of Seven Brake Servicing Facilitites. Asbestos.

PB2005100060

Publication Date	1979
Personal Author	Johnson, P.; Zumwalde, R. D.; Roberts, D.
Page Count	46
Abstract	A major objective of the National Institute for Occupational Safety and Health (NIOSH) is to determine environmental exposures of working populations through research, surveys, and industry wide studies. Accordingly, NIOSH is presently conducting research to characterize dust exposure resulting from vehicle brake servicing operations. Of particular interest are the small diameter potentially irrespirable, asbestos fibers generated by these operations. Limited studies have suggested that such emissions may be associated with asbestos-induced diseases. An estimated workforce of 900,000 brake mechanics and garage workers in the U.S. are potentially exposed to asbestos. An estimated 118 million pounds of asbestos are used annually in the U.S. for the production of brake friction materials. In addition to asbestos, other materials which are used in the manufacture of brake linings such as lead, zinc, copper, and iron pose other potentials for exposures. Rohl and Langer identified thirty materials or compounds that make up the binders, fiber reinforcers, and the property modifiers as being present during brake lining manufacturing.
