E. Worsham - Longview COPY TO: Mr. H. C. Willms - Patterson DATE: April 10, 1973 PLAINTIFFS EXHIBIT RMC-408 Several of you have called me since our OSHA inspection due to an employee complaint on saving asbestos and Marinite. As you probably.know, we were issued a citation and fined for being over the limits on asbestos fiber in air while sawing. As a result we decided to engineer out the use of asbestos and Marinite. Our approach to this was to find substitutes where we could. In general our asbestos replacement program to date can be summed up as follows: flO Crucible syphon gaskets of 1/4" asbestos millboard are to be replaced with gaskets cut from mineral / wool felt such as Eagle-Picher's Superglas. */ AmettAn <QftrO 2. The same material is being used as a pad on the,pot shell supports in place of the'1/2" asbestos mill board. These supports are the brick which our pots sit on in the hole. 3. An aluminum plate vrith a groove to hold 1" square fiberglass braided packing is being used as a crucible pouring spout cover while tapping. 4. Mineral wool insulating cement is being used in ^ place of insulating cements of asbestos or asbestos shorts. Other than pipe and steam jacket insulation, wc use this for dough balls in the Cast House and to seal around rollcctor bars. i I RMC0800260000620 Page 2 5. Glasrock products are being used in the Cast House <\ to replace Marinite in troughs and casting boxes. * No suitable substitute for Marinite mold inserts has been found as yet. 6. Several substitutes for anode leg insulating pads have been'requisitioned for trial. A supply of Marinite leg pads is being maintained until a re placement is finned up. AEW:tg- RMC0800260000621
