'hila fre Indicated that there are definite problems wich the membrane filter method as regards enforcement purposes, it is a cool for the manufacturer to use in monitoring his work areas. Mr. Weaver mentioned that-the Cernar.s have been working with a gravimetric system. A prooler is the fact that ail airborne materials in a friction materials factory are not necessarily asbestos, and chat the gravimetric system does net distinguish between asbestos and ether materials. Mr. ''eaver fa.lt that any new system to replace the membrane filter mechod is far off in the future. A Member asked concerning the E?A emissions requirements where they are in effect legislating dry collectors over wet collectors. Ire question was ,rhy." !ir. '.leaver replied that the wee collectors require very high horsepower to reduce the visible emissions to zero. In essence, it is very difficult to get "no visible emissions" with a wet collector. Another question concerned clothing and Che 1SEA regulations. It was pointed out that several manufacturers use an outside cleaning service for die clothing that is worn in the work arse. Mr. Heaver emphasized that* the manufacturer should specifically notify the people doinn the cleaning that this clothing is used in an asbestos handling work. area. Another question had to do with the recommendation chat Mr. leaver made that all-boxes or cartons containing friction materials have the OSUA label., imprinted thereon. In this case, the question concerned a drilled taper ground broke lining set ready for installation on shoes. Did this require the CSuA libel, since it was most likely that there would be no subsequent drilling, cutting, or grinding to put asbestos dust into the atnesphera? llr. Heaver suggested that there is always the possibility of additional cutting, iriilinc, or grinding and that he fele the C.siiiA laoel should be used here also. Hit- point is that in tnasc subseauent operations the asbestos can be raised to levels above the 5 fiber per cc limit in the CS2A standards. This will be even more of a problem whan the standards drop to 2 fibers per cc. Mr. Weaver felt the OS*IA regulations indicate that if there may be subsequent operations, the label should be used.
