Havriila. and the writer investigated employee exposure to airoorne~asbestos fibers m Department "640. The results of this investigation are listed on the attached data sheet opposite the correspond ing job de sc ri pt i o n . Note that both the peak exposure levels and the eight hour time-weighted average exposure levels were found to be well below their respective CSKA limits. At the time of this investigation, the use of the small celt sander m the Irak Laboratory for grinding and finishing asoestos-cased friction materials was brought to cur attention Industrial Hygiene recommends that this belt sander be equippec with local exhaust ventilation. A flex duct serviced by the existing dust collector should provide adequate control of any asoestos fibers generated at this work station. 'cart t: medical examinations . l o g o ;j ) (3) states, 'every employer snail provide or make availaole compre hensive medical examinations to each of his employees engaged m occupations exposed to airocrr.e concentrations of asbestos ' fioers.' Altncuc.n one regulation does not define exposure, recent court decisions 'rave defined exposure m terms of the _cwer ceteccic.o limit, i.e., 1.1 fibers per rucic centimeter or air. o m c e the eigr.t .tour time-weighted average asoestos exposure of mechanics removing brake drums has tot been shown to exceed G.l fioers.ee, ve can conclude that annual examina tions are not required for Department "540 mechanics. However. Industrial Hygiene recommends that the cia.nt continue to provi> annual medicai examinations to ail employees assicnea to asbes grinding operations. In addition, we recommend that a single asoestos medicai examination be offered to the employees who ere stationed ir.
