In addition, the Corporation provides disposable aproqp to those employees who'work in area* where t n e i r personal c lo th in g may come in c o n ta c t with loose a sb esto s d u st. I t i s th e re fo re evident th a t Chrysler Chemical has achieved more chan simple compliance w ith the OSHA Regulation, and we b e lie v e thac the p la n t has, in f a c t , provided p r o te c tiv e garments for chose employees whose perso n a l c lo th in g may tend to become contaminated w ith a sb e s to s f i b e r s .

In regard co the wording of the employee over-exposure n o t i f i c a t i o n l e t t e r , we do not o b j e c t to p o in tin g out in the body of the l e c t e r thac h i s exposure exceeded allow able l i m i t s , but we do o b je c t co p ro v id in g th e employee w ith the numerical r e s u l t o f th e a i r sample a n a l y s i s . We b e lie v e thac the e v a lu a tio n of a i r sampling r e s u l t s snould be the re sp o n sib ility of a professional in d u s tria l hygienist, who has th e knowledge and experience required to put t h i s type of Information in the correct perspective. CHRYSLER OS12W - 1- H. Receiving of Asbestos Shipments I n d u s tr ia l Hygiene agrees with Or. M ire r's reeonnendatioti regard ing the receiving of asbestos shipments. U FRICTION PRODUCTS BUILDING A. Weigh-Up S ta tio n OSHA r e g u l a t i o n s re q u ire th a t a sb e sto s waste must be disposed ot m sealed impermeable bags wnen d is p o s a l may produce, "in any reasonably fo reseeab le u s e ," an airb o rn e asbestos f ib e r concentm tlon which is in excess of the allowable lim it. In lugard to t' e above r e q u i r m e n t , I n d u s t r i a l Hygiene f e e l s tnac asbestos waste .hould be disposed of in impermeable bags r a th e r than by attempting t ' c o n t r o l a irb o rn e le v e ls by i n s t a l l i n g lo c a l exhaust v e n t i l a t i o n for the wascc containers. fri r e l a t i o n to p o in t 4 2 . , see our v e n t i l a t i o n indic.ncnr comments l i s t e d under I . C. We have no o b je c tio n to providing covers for tr a n s p o r t c a r t s , but i t should be noted thac such covers would provide only marginal e f f e c t i v e n e s s , because they would have to be removed p r i o r to skip hoist loading. B. Lodige Mixers I n d u s t r i a l Hygiene agrees w ith Dr. M i r e r 's housekeeping and main tenance recommendations for th e Lodige mezzanine. However, we do take e x c e p tio n to p o in t #2. A ir sample r e s u l t s have shown th a t the d u s t which i s seen to escape from the skip h o i s t when the Loading c a r t i s turned upside down, i s composed mainly of non a s b e s to s p a r t l c u l a c e . We b e lie v e a t t h i s time th a t the use of ad ditional engineering controls to prevent airborne dust at the Lodige skip h o i s t , would not prove to be a cost e ffe c tiv e control measure. C. B lpel P re s s I n d u s t r i a l Hygiene b e lie v e s t h a t much of th e re c e n t in c re a se in employee exposure to a irb o rn e a s b e s to s d u s t a t the Blpel work s t a t i o n s i s due to haphazard handling of the loose disc brake pad m a te r ia l. I f a d m in istra tiv e c o n tro ls cannot reduce che magnitude - o f employee exposure tu a s b e s to s d u st a t the Blpel work s t a t i o n s , a d d i t i o n a l en g in eerin g c o n tr o ls w i l l have to be evaluated. A problem, which should be noted, is th a t the in s t a l l a t i o n of high c a p tu r e v e l o c i t y lo c a l exhaust v e n t i l a t i o n a t the Blpel work sta tio n s could resu lt in underweight pads, because of the related lo s s of the loose d isc brake pad m a te ria l through the exhaust system.
