ER wxsB nmuxzcx manufacture Edited bytRobert L. Hout, Industrial Chemist When asbestos is uaad as an Insulation agent in the manufacture of *ire it enters the plant In a refined form, haring been through a previous snoufacturing or processing treatment at some asbestos factory, which has sonditloned the raw supply of asbestos* Thus we find two general types of asbestos supply, one the yam of asbestos in the spool fora (to be used for braiding the outside of the finished wire), and the other Use bett, ar lap, form of asbestos which is loosely wound, in a reel (this is the form that is used on the carding machines). High grade asbestos, of long staple and free-from-iran content, is used in sire manufacture intended for eleotrieal insulation* The wire manufacturer is more oonoeraed with removal of a rather long* stapled waste, than the finer dust partioles which are found associated with csbestos-ore processing about the plolcsr-oarding machine for example. However, this asbestos by-product, if allowed to esoape into the workroom, would soon float into the far boundaries of the plant and hang like Spanish moss, even from the rafters, and settling on belts, pulleys and equipment. It soon gats beyond the oontrol of good housekeeping if unreooved at its origin* Asbestos has a deolded abrasive action and its presonoe is not beaefloial to the long life of plant equipment with whioh it comes in oontaot. The plant procedure of the General Slectrio Company's wire works at York, Pennsylvania is considered a model in its asbestos waste removal system, and on illustrated deeoription of the processes used, mokes up the basis of this Safe Praotlee Bulletin* EXCASB 0021
