Petkash Jim Fisher ASBESTOS USED IN FRICTION MATERIALS SALES DEPARTMENT LETTER #86-04 JS . - '5, *i-f?'S" This is an update on our position on the use of asbestos based ' friction materials in Airflex products. /% ' C i:i \ In essence, our position is the same as that originaliyjexpressed in BobRosenow's Sales Department Letter #76-46 back in l-976., -Although there is a significant asbestos content in these materiaLs,*:to the best of our knowledge, very little of this asbestos5is^liberated to the air in normal use of the clutch and/or brake; The very localized hot spots at the friction surface chemically changes'-the asbestos into other harmless minerals. What litt^.asbestos that is liberated, most likely will not result'fdconceptrations anywhere near what would be considered hazardous!Ip^tljs necessary to document meeting the OSHA specification, physical measurement of the airborne concentration of asbestos <fnringr:a:'t^pical day of operation will be required. J 's'" The only practical hazard presented,0% these friction linings would be if the customer attemps%o machine, grind or sand down the friction blocks. These actions may"release significant quantities of asbestos and expose ^#^>r.tanam>sto` a potential hazardous asbestos concentration. WE DO iNOT RECOMMEND THAT ANYONE MACHINE OR OTHERWISE PROCESS THE ASBESTOS BASED,FRICTION BLOCKS IN ANY WAY. '' In spite of -v** (: A ff *.*'**' .; temotepeets of the hazards associated with the ' asbestos f^i^tion materials, we are in the process of replacing them with non-as&estos materials as our standard material in all of our produetj^ih'd" ,fThis is primarily due to a recent increase in demaddv, SVs .yohiafce aware, we are in the process of changing the standard .friction material for our VC, VE, E, CB, EB, DBA, DP and HD products to rioh-asbestos. The CS, CSA and CTE product lines and the 'Slip dinings"5"will follow shortly as soon as suitable materials are found~and sufficiently tested 7 ` Jim Fisher 1 V ' JF/bm V ' form 30-23 (Rev 12/63) SCF-EC-3065 FAW 17188
