A sb e 31-. os Pm id od Sleeving - for Lead Wire Puses - 379^0-150 (J_iovemh'-r 2, 1972'^ J. T. Parly I-:r*. 1!. A. Lonyfellow: In answer fco ti I Coir.7 --------------- , - - adhesive bonded asbestos braided sleeving. He asserts that this material meets OSIIA regulations. If this material is satisfactory to you and the OSHA inspectors it will be the closest substitute for current material. It would need further evaluation for corrossivity, electrical conductivity and other characteristics. This work would be carried out only Jf S* J. L you c< Ld approve bonded asbestos braided sleeving in prln dole. As y O'J. cxpl a I: fuses are made each yea: on this si xty yo; old design. The asbestos braided sleeving is arou nd the lei melt wire and this assembly is enclosed .in a vulc ani sed fil - tube. Any other alternate material would requ ire con sii rable proof testing of the fuses to assure co rr r\ ope ra jn because the thermal characteristics would be q uit e cliff nt. It would be difficult to find a material othe r t ban as' >tos sleeving, capable of condensing the lead fume s f rom th Durn out of the melt wire. Even the iae<` p q h a sto 3 v;oiUl retains the lead fumes, If you are unable to use the bonded asbestos braided sleeving, then it might be most practical to eliminate the lead wire and Its toxic fumes. The sample of bonded asbestos braided sleeving is separately transmitted to you. ORIGINAL SIGNED GY MH-1513-JTK-meb J. T. Early Att. Maashant Letter Cop ), r. * 1 * \ JL t\ .
