It is imperative that all operations that involve cutting, milling, and sanding of materials that contain asbestos be locally ventilated. The dust collector used must be designed for collection .1 ^
of asbestos fibers. Any shop vacuum should not be used tor loca 1 i zed I/' ventilation and especially one not equipped with a filter deslygeo dk%':>
asbestos fiber collection. A collector not approved for collection of asbestos fibers may actually make matters worse since the^fiber%,may pass through the filters and spread asbestos fibers over/a! iarger area. Exhaust ventilation must comply with ANSI 29.2-197'l:. ^ *

While the present OSHA standard, 29 CFR 1910.1.001, .limits workers' asbestos? exposure to two fibers greater thhp" f i.V.e`rtilcrometers in length per cubic centimeter (fibers >5 /cc) , mahy he'ATth experts believe that there may not be a safe level for.Carcinogen1 exposure.

factors affect obtaining^ a propej fit. For example beards, sideburns,
