A FROM MICHAEL J. VAUDREUIL PITTSBURGH OFFICE TO INDUSTRIAL HYGIENE CONTACTS DOMESTIC & FOREIGN 1980 August 14 RE: ASBESTOS REPLACEMENT PROGRAM As part of Alcoa's asbestos replacement program, a listing of applications and substitutes for asbestos was compiled and distributed in August of 1979. Since that time, some headway has been made in the development of substitutes for several uses of asbestos. The progress to date is reviewed in the attached memorandum. An updated version of the original master listing is in preparation. Distribution of the revised registry is planned for 1980 November 01. However, critical to this effort is additional input from all Alcoa locations. Information on current plant asbestos use, as well as any successes (or failures) with substitute materials is requested. In order to meet the November 01 target date for release of the updated list, replies should be received by 1980 October 01. This ongoing exchange of information is necessary for the continued success of the program. With the assignment of Haig Sakoian as Senior Industrial Hygienist, Tennessee Operations, I have assumed the responsibility for overall coordination of the asbestos replacement program. Therefore, please direct all future correspondence to my attention. f/> faj?L &//*/' '' MICHAEL J.

VAUDREUIL PITTSBURGH OFFICE TO MEMORANDUM 1980 August 14 RE: ASBESTOS REPLACEMENT UPDATE The following sections summarize the progress made over the past year in the search for asbestos substitute materials. The discussions are organized by asbestos product, and within each section by specific application. A supplemental list of substitute material suppliers is included. 1. Molten Metal Marinite There is presently only one necessary use for asbestos in ingot plant operations; that is, header applications. There are adequate replacements in Johns-Manville's Marinite I and Pyrotek's Pyrotherm B-2 board products and R-680 for all other melting and casting needs. Therefore, Molten Metal Marinite need not, and should not be used for dams, basins, troughs, etc. However, at present, the suitability of substitute materials for use as floats is questionable. Some header-related applications of asbestos have also been eliminated. After header design modifications, R-680 can be used for all FDC headers 635 mm (25 in.) and smaller. With this substitution, Lafayette, Vancouver and Massena should be asbestos free. Molten Metal Marinite must still be used for HDC and tool and jig headers. R&D programs at ATC will continue to address these areas. 2. Asbestos Rope Fiberseal A-l rope (Pyrotek, Inc.) can be used in place of asbestos rope for sealing the gap between the mold and bottom block in FDC casting operations. It prevents metal leakage and its good thermal stability allows it to be reused numerous times. It may also be used for sealing joints in pouring troughs. Z-5 treated fiberglass rope (Pyrotek, Inc.) can be used successfully as a crucible< lid gasket on vacuum-type potroom tapping crucibles. It replaces the presently used Johns-Manville 872 or 702 asbestos gasketing material. However, Z-5 will not replace gaskets made of twisted aluminum foil. Plants using foil gaskets will in all probability have to continue that practice. 3. Transite Transite, a structural, fire-retardant asbestos/portland cement board, is used extensively in construction. ATC has tested glass-reinforced cement (GRC) sheet as a replacement for transite. Qalcoa 4 MEMORANDUM Page 2 1980 August 14 Although GRC boards are not suitable for high temperatures (>320C) or molten metal contact, they can be used in fire resistant components, pipe work, furnace shells, etc. Physical properties are similar to transite except that GRC board has lover shear strength. However, proper engineering design can compensate for this deficiency. 4. Thermocouple Insulation Finding a suitable replacement for asbestos-coated thermocouple wire has been particularly troublesome. Many substitutes have been rejected because of low abrasion resistance and/or friability at high temperatures. A new ceramic fiber product from 3M, Nextel 312, purportedly exhibits excellent abrasion resistance and immunity to thermal ock. The attached brochure provides more complete product info:.ution. If physical properties of Nextel 312 are as claimed, it should prove to be a suitable substitute for asbestos coated wire. Comments and additions to the information presented are encouraged.

VAUDREUIL:mlf 80-08-05 APC 003465 Product Bulletin Thermocouple Insulation At last: a practical high-temperature insulating material that eliminates the two biggest causes of thermocouple failure. Dimensional stability and abrasion resis tance have always been big sources ol trouble for high-iemperature insulators The most commonly used fibers- those made from vitreous silica - typically shrink, abrade, fray, or crumble to the point where wires become exposed This obviously creates a potential for inaccurate tempera ture readings. The traditional alternative, ceramic beads, solves the problem of ex cessive shrinkage and abrasion, but only at a high cost for labor Now there s a better alternative Nextel" 312 Ceramic Fiber from 3M Nextel 312 withstands operating temperatures of 1000C F to 2600* F. continuously. It shrinks less and resists the combined effects of abrasion, flexing, and high temperatures better than asbestos, quartz, and vitreoqs silica fibers. It also offers good chemical resistance and immunity to thermal shock. Proven dimensional stability. A recent test compared the dimensional stability of Nextel 312 and vitreous silica by heating sleeves braided around separate lengths of wire for % hour at 2000* F. When the samples were removed from the fur nace. Nextel 312 still covered the wire completely, thanks to shrinkage of less than i per cent. The vitreous silica fiber had shrunken by roughly 12 per cent, leav ing an inch of wire exposed at one end Nextel 312 braided around a thermo couple wire and heated at 2000* F tor v* hour shrank 7%. Vitreous silica handled the same way shrank 72%. Exceptional resistance to abrasion. In another test, a Duplan silk-testing ma chine" was used to compare filaments of Nextel 312 and vitreous silica. Blades were rubbed back and forth on the two products after they had been heated for % hour at 1000- F.. 1500* F. and 2000* F. Results showed that Nextel 312 tasted 2Vj to 5 times as long as the vitreous silica fiber This means that at 1000* F. Nextel 312 performed 400 per cent better The figures for 1500* F and 2000* F were 300 per cent and 166 per cent respectively No residual acids or chlorides to cause etching of wires. Because Nextel 312 Ceramic Fibers con tain no residual acids or chlorides, there s no chemical present to corrode or etch the wires Even in a test involving exposure to 96 per cent relative humidity, no notice able electrolytic corrosion was detected. The test consisted of putting Nextel 312 fibers m contact with two unconnected bare #32 copper wires A 250-voii D C po tential was applied across the wires After 20 hours, corrosion was determined by calculating the ratio of anode wire tensile strength to cathode wire tensile strength Three test runs produced ratios above 0.99: since the maximum ratio possible was 1.00. there was essentially no elec trolytic corrosion Available from your local thermocouple supplier. Nextel 312 is being manufactured in pro duction quantities right now.

It comments on successful and unsuccessful substitutes for asbestos. Considerable progress has been made in the plants over the past two years in implementing safer substitute materials. This report should be helpful to you in knowing the results of the experiences at the other plants. It might also serve as a useful guide to be used in your next staff meeting to explore your success in making your plant as free from asbestos-containing materials as possible. We are asking that plant Engineering and Procurement Managers keep us advised of their results in seeking safer substitute materials. This will permit us to share the information throughout the plants. The very worthwhile efforts being made in the plants are much appreciated. E. E.

Spear, ATC-C APC 003468 Industrial Hygiene Technical Bulletin NO. 82-3 Date: 1982 February 16 RE: ASBESTOS REPLACEMENT The Asbestos Replacement Program was initiated a number of years ago as a result of the health hazards associated with handling asbestos and asbestos-containing materials. The program is a cooperative effort between Production, Engineering, Procurement, Research, Safety and Industrial Hygiene at the plant and corporate levels. It continues to be Alcoa's objective to replace all asbestos with safer substitutes whenever possible. The only exception is that we do not encourage the immediate removal of affixed asbestos insulation so long as it is in good condition. When it does become necessary to replace worn asbestos-containing materials, safer substitutes should be used. When asbestos is being removed, proper precautions must be taken to protect employees from inhaling asbestos fibers. Considerable progress has been made in the past two years toward making Alcoa plants asbestos free. The attached report summarizes plant experiences and identifies successful substitutes. It also identifies unsuccessful products that have been tested and failed. The report contains sections on General Applications, Potroom Use, Carbon Bake Use, Wire, Rod and Bar Use, and a List of^Asbestos Replacement Manufacturers. This report should benefit each plant based on the experience in other plants. To continue to coordinate these efforts, it is important that Engineering and Procurement at each plant copy the Corporate Industrial Hygiene Division on all efforts made towards asbestos replacement . . . whether positive or negative results occur. Please review this present status report and advise us of any new experiences at your location. If we can be of any further assistance, please let us know. SCOTT M.

SAKOIAN PITTSBURGH OFFICE TO 1979 July 30 RE: ASBESTOS SUBSTITUTION Attached is a summation of asbestos materials currently in use at Alcoa locations. Included in the listing are: - The material and its use - The number of plants using the material Whether or not there is a potential for employee exposure Potential replacements, if available -- and manufacturers (Page 10) Much effort has been extended to reduce and eliminate asbestos uses in most locations. However, as can be seen by this report, many uses still exist. Because the continued use of asbestos products may result in unnecessary health hazards and concerns to our employees, as well as additional costs to Alcoa to comply with specific provisions of the c^HA Standard, we believe it is in Alcoa's best interest to continue eliminating the use of asbestos products wherever possible. This does not mean that all existing asbestos should be removed immediately which, as in the case of sprayed-on insulation, could create unnecessary exposure potentials. Rather, a systematic effort should be made to discontinue uses, when feasible and practical, by substitution or elimination. By creating this listing and maintaining frequent updating via feedback from all locations, each plant can be provided with the information necessary to attain this goal. Mr. J. M. McCollum, Pittsburgh Office Mechanical Engineering, has been coordinating such an effort for asbestos replacements in potrooms. A list illustrating Alcoa's experience with potroom replacements is shown on Pages 7, 8, and 9. It is hoped that this type of registry will be extended to cover all asbestos uses for all locations. To achieve this, it is asked that each location copy this office on all efforts made towards asbestos replacement... whether positive or negative. This information will then be disseminated to all locations on a periodic basis so that each plant can profit from the experience of the others in the Company. Any questions, comments, or additions to the attached would be appreciated. HAIG G.
