A nother member a d v ise d that they had'taken out a l l a ir hoses around b riq u e tte p resses and.other machinery where loose asbestos i s handled befo re i t becomes locked in . S u r p r is in g ly to some members, asbestos sam pling in d ic a te d Chat the in s p e c t io n and d r i l l i n g lo c a tio n s were problem a r e a s .

This study by NIOSH was t o check over m edical records and o th e r such item s to attem pt to put th e problem in p ro s p e c tiv e . NIOSH had in d ic a te d to the co o p era tin g m anufacturers th at th e inform ation they were p rovid in g would be kept c o n fid e n t ia l.

A member questioned what happens when the asbestos c o n c e n tr a tio n in a work a re a exceeds 10 fib e r s per cc (th e c e il in g co n ce n tra tio n in the OSHA r e g u la t io n s ) . The answer is th at the employer must n o t ify the worker so exp o sed , in w r i t i n g ,, th a t he was exposed to such a co n ce n tra tio n and the worker must wear a re s p ir a to r in th a t a r e a .

The next l a the han d lin g o f the p ro d u cts w ith supposedly locked -in aabeatoa during subsequent op eration s, such as d r i l l i n g , grin d in g, in s p e c tio n and b o x in g .

' ' I t was reported du ring t h is to p ic th at th ere was a h ig h e r c o n c e n tr a tio n o f asbestos in the a i r in th e In sp e ctio n Department than most members had r e a liz e d . One mfember in d ic a te d th a t when p a lle t s 'o f brake lin in g s were shipp ed there apparently is ad d itio n al dust created during tran sp ortation . The question o f su rface dust on the working su rface of a brake lin in g or a c lu tc h fa c in g vaa d iscu sse d . Where members have taken a c tio n to reduce th e d u sty typ e s u r fa c e , they have found th a t they have a c tu a lly a lte re d the f r i c t i o n a l c h a r a c te r is tic s o f the m a te ria l during the e a r ly m iles on a v e h ic le . In o th e r w ords, the brakes are not very responsive fir in g the early mileage a ft e r r e lln e . In the AIL ccoc Lfcadatlons, iC i s c u r e t t e d t h f t where a r?nufactunr i s sh ip p in g h is brake lin in g s or clu tch facin gs (locked-ln-asbestos products) he should n o t if y the user o f h is product to the e f f e c t , ''Power bench saw s-w ith out c o lle c t o r s should not be used In cu ttin g thin product. I f th is is im p r a c tic a l, operators . should be provided w ith a Bureaulof- Mines approved r e s p i r a t o r ." I t was suggested that a n o tific a tio n beipnt in boxes o f brake lin in g s ox clutch facing* being shipped to custom ers. A sample o f the cau tion la b c la suggested is attached to these m inutes. Mr. Feierabend in d icated th a t t h is recommendation would not be accep ted warmly by many m an u factu rers. Mr. Wagner o b je c te d to the recommendation th a t warning n o tic e s be put in the brake lin in g s as he f e l t i t / was another "red f la g " th a t would b rin g more harm to the in d u s tr y than the j a lle g e d good th a t would come from e n clo sin g such n o t ic e s . S e v e r a l members have I had customers c a l l in to t h e ir S a le s Departments askin g i f th e h a n d lin g o f lo ck e d -in -a sb e sto s in brake lin in g s and clu tc h fa cin g s i s a hazardous c o n d itio n . Another asked i f t h is n o t if c a t io n was a requirem ent o f th e OSTIA r e g u la t io n s . I t was in d ic a te d th a t t h is was not s p e c i f i c a l l y req uired by th e OSHA r e g u la tio n s . The concern i s , do th o se custom ers doing a d d itio n a l g r in d in g and d r i l l i n g o f the brake lin in g s or clu tch facin gs create working con d ition s where the con ce n tratio n of asbestos would be a h azard .' S in ce sm all m anufacturers are exempted from the OSHA r e g u la t io n s , they w i l l probably not be run n in g t e s t s . Larger customers w i l l , o f c o u rs e , be covered under the OSHA r e g u la t io n s and i t i s expected th at te s t s w i l l be run in these m anufacturers' work a r e a s . Whether the I n s t it u a would recommend such la b e lin g in fin is h e d p ro d u c ts shipped to the customers was. n o t d e cid e d . I t was f e l t th a t t h is s u b je c t sh o u ld re c e iv e fu r th e r co n sid e ra tio n from .the Members o f the Committee before a recommendation is made. One member commented th a t th ere were in s tr u c tio n s by some m an u factu rers a d v is in g th a t b lo v in g out the wear d eb ris from used brakes was n o t recommended. This s u b je c t o f recommending th a t brake lio in g and c lu t c h f a c in g ' m anufacturers in clude a warning sheet in th e ir shipments appears to be somewhat c o n tro v e rsia l and i t is suggested th a t th is m atter re c e iv e some s e r io u s d is c u s s io n by the Members o f the Committee w ith those re sp o n sib le at t h e ir com panies.

Weaver in d ic a te d th a t th ia p o s s i b i l i t y was q u ite remote. A pparently the q u estio n arose a f t e r an OSHA v i s i t to the member's p la n t . In response to a q u e s tio n , one member in d ic a t e d i t takes about tvo months from the OSHA sam pling u n t i l the OSHA report i s re c e iv e d .
