' FROM E . E . RUMBERGER PITTSBURGH OFFICE TO 1982 February 16 RE: ASBESTOS REPLACEMENT The attached Asbestos Replacement Report is being distributed to plant Department Managers and Superintendents for Engineering, Procurement, Safety, Environmental Control and Industrial Hygiene. It comments on successful and unsuccessful substitutes for asbestos. Considerable progress ha.s 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 ALCOAOO00008535 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 Ba'ke 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.

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/' //' JL 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.

VAUDREUIL:mlf 80-08-05 ALCOAO 000008556 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 of trouble for high-temperature insulators. The most commonly used fibers- those made from vitreous silica - typically shrink, abrade, fray, or crumble lo 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 1000 F to 2600 F continuously. It shrinks less and resists the combined effects of abrasion, flexing, and high temperatures better than asbestos, quartz, and vitreous 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 '/j 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 1 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. for 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 Mi hour at 1000 F. 1500 F. and 2000 F. Results showed that Nextel 312 lasted 2yi 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 in contact with two unconnected bare #32 copper wires A 250-volt 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.

For lining Pots we require 1", 2", and 3" H-temp asbestos blocks which we had being importing from USA, but due to problems to obtain from goverment the necessary import permits, we were forced to research our local market and fortunately we found a substitute made out of a mineral fiber instead of asbesto. This material has been in use for several years and we find it suitable for our requirements. Other materials covered under these subject are the following: 1. - Molten metal marinite 2. - 1/32" x 36" wide asbestos paper used on our DC Casting Filters. 3. - JM-C-790 Packing Rope Braided asbestos, wire inserted, used for Cc.- Mr. M.J.

William re: "Asbestos Usage at Pontiac Street" Ref. 2) N. A. William letter 29Apr76 to Robert P. Carter This letter will serve to confirm our telephone conversation of earlier this week. Following the listing used in reference 1, I will comment on the specific items listed by Mr. Dewart. Item (a) Exhibit A and Exhibit A-l With respect to the various items of asbestos packing cloth and rope shown in these stock cards, I do not believe that we can provide you with a hard and fast rule to be applied. If in the use, including removal and replacement of any of these materials, it is likely that a worker can have even an infrequent exposure to a visible amount of airborne fiber or repeated exposures to low levels of airborne fiber, such a worker would be subject to the medical surveillance, monitoring and training requirements of the asbestos standard. These requirements are sufficiently burdensome that it would be desirable to find non asbestos replacements for any such applications. Item (b) Transite pipe and sheet. It is probable that in the installation of this type of material, it will be sawed, drilled, and cut, resulting in generation of airborne fiber. In addition, when this material is subsequently removed in the course of maintenance or demolition, it is almost impossible to prevent the generation of airborne fiber. Therefore, these applications constitute logical ones for the use of non-asbestos containing alternates. If Mr. Dewart would supply to Mr. M. J. Caprio information regarding the service requirements for these products, it will enable him to recommend or seek to develop sources of non-asbestos containing alternates. ALCOAOOOOOQ9583 N. A. William 03Jun76 Page 2 Item (c) Kaylo and Kaylo 20 pipe insulation and block insulation. If, in response to Mr. Dewart's April 12, 1976 letter to the vendor, you learn that this product does still contain asbestos fiber, our recommended approach would be the same as for Item (b). Item (d) Johns-Manville Superex Block Insulation Johns-Manville has had available now for several years their Superex AF grade material which is as asbestosfree alternate to the original Superex product. We would recommend immediate conversion to this product because of the strong likelihood of airborne fiber exposures both in installation and removal of this type of material. Item (e) Johns-Manville Marinite 36 Insulating Board This item falls in the same category as Item (b) above. If Mr. Dewart will furnish to Mr. Caprio the service requirements for the applications involved, he will assist you in locating satisfactory non-asbestos alternates. Item (f) Eagle-Pitcher Super 66 Insulating Cement Since the vendor's letter of April 19, 1976 that this product is asbestos-free, its use not present any special problems as long as nuisance dust control is exercised. indicates should good I'm sorry for the delay in replying to your letter, but hope that this information will be helpful.

William ALCOAO 000009585 FORM 62 From D. Dewart internal correspondence To N. Date April 13, 1976 RE: ASBESTOS USAGE AT PONTIAC STREET Reference is made to the concern about asbestos products an^Lspecifically to the Carter/caprio memo of 3-30-76 to you. Poundwise/or quantity-wise, as a general statement, we use only a relatively small amount of asbestos bearing items and an employee works with such items only infrequently. But since asbestos has unique insulation and high temperature characteristics, asbestos bearing compositions are employed in a number of specific uses throughout the plant. We have attempted a general listing of the products used, with comments where appropriate. It is difficult to attach definite parameters for substitutes -- it is much easier to state "... or equivalent." Seriously, it is hoped that the onus can be placed on the makers of substitute materials to advise whether their product can substitute (or closely substitute) for the asbestog-bearing product. Many of our temperatures are in the 700 F. to 1500F. range and possibly don't really require all that asbestos can protect against. I am confident substitution can be readily made in some cases and as regarding our annealer sleeves listed below, we already have made substitutions. I think we need help and advice on the use of asbestos gasketing, asbestos rope, etc. where the exposure seems so slight and acceptable substitutes may be hard to come by. Our Known List Followsj (a) Exhibit A and Exhibit A-l - listings from our storeroom of various asbestos products used relatively infrequently as a rule. Many of these items are supplied by our local vendor, Wayne Pipe and Supply, and many are manufactured by RaybestosManhattan. (b) Transite pipe and sheet.

Roberts, and felt that we should inform you of the action that has been taken to eliminate where possible the use of asbestos on this site. In metal melting and pouring operations: 1. Replacing the seal between static and portable pouring launders with Kaowool, a proprietary brand of ceramic fibre. 2. Using Ciment Fondue and crushed refractory brick instead of rammed asbestos fibre or Marinite board as launder lining. 3. Substituting hand-formed furnace tap-hole plugs made from dampened asbestos fibre with pre-formed Fibrefax Cones, made from Aluminium Silicate. 4-. We are still using pre-machined (at the supplier's) Marinite components for pouring floats (distributors) which we assemble prior to use, but are endeavouring to improve handling, transportation and storage to reduce minor damage and the subsequent dust and small particles arising from poor housekeeping. Elsewhere in the plant we are examining protective clothing, e.g. gloves, for handling hot rolled plate and seeking alternatives. As a result of information recently released in this country there has been a spate of reports in the media and we enclose photocopies of articles reproduced in two of our more responsible national daily newspapers.

In a 45-ps'e report released yesterday, Sir Alan concludes that "the quality of the attention given to Acre Mill was not as high as it could and should Lungs starred have been," He strongly suggests the inspectors should have prose cuted the owners for failing to implement adequate dust con trol measures. Community leaders in West Yorkshire claim that 40 former employees have died and more will die from the lung disease asbestosis contracted at the Acre Mill p! int. closed down by its owners in 1970. Lawyers representing the workers sav that Cape Indus tries. which ran the factorv, have paid out same 2 million in damazes in the Dast six years. All but two of the cases have been set'led out of court, with the highest single com pensation figure standing at 35,000. Fresh concern In Hebden Bridge yesterday there was fre'h con.-rrn over the dumping of asbestos waste in the neighbourhood. A junior and infant school 100 yard.; from or.e of the bizgest tins has halted nature w-jlks :r. the area, and t.em bers of u local Ashe*?.-? Ac-mn Committee are pressing the* V.'est Yorks County Council to cover the asbestos* waste. The Ombudsman's r*rv>rt is certain to be used by M ?s to demand a public inquiry into the contin l'!":* tracccios at Hebden Bridge ar.d to investi gate the benefits and hazards of asbestos. "I shall use this as a batter ing ram to get a verv urgent pubJc inquiry into all asn-'cts of asbestos." said Mr Max Madden. Labour M P for Sowerbv. who brought the issue to the Ombudsman a year ago. `` The cent nun: tv sreuid be ajblfr t*> *; e.'i ir the* risks ar" ar-p?tab' in The light 81 the bertiti of asocstos." Asbestosis results from the scarring of the lungs by tiny dust particles. There is no known "safe" limit for the estimated 100.000 people workin? closely with asbestos, and the disease can take as long as 15 to 25 years to mature. The Ombudsman's reoort tackles or.iv the role of Gov eramane factorv inspectors. "I think that the district staff at Halifax--the rrspons.bie in spectors--could and should have shown greater determ ration at various times over several vears to put further pressure on the management at Acre Mill." Sir Alan said in the conclusion to bis report. "I am not convinced that they were sufficiently derisive either in convcvir.g to the management the sense of urgency that was appropriate or in pursuing the question of a prosecution when, over a period of vears, improve ments were not ioi thcomir.g." `Model' plant The report discloses that Acre Mill was for a time regarded by local factory inspectors as a "model" plant to which trainee inspectors were taken to demon strate the working of regulations for the asbestos industry. Regu lations framed in 1931 were tightened in 1969. Sir Alan's year-long Investi gations into Acre Mill show that inspectors' reports on the plant were peppered with criticisms for almost 20 years. The threat of prosecution was mooted at least three times, and one fetmer factory inspector told the Ombudsman that he would " probably " have reconsidered taking Cape to court had he not been transferred from the area in 1966. The report quotes the minutes of a conference held by the chief factorv inspector last year "that with hindsight it might have been better to have allowed the district inspector to prosecute.'' ` Over friendly ' But the Ombud-mn exoner ates the fa.-tnrv i--'::v..'rr.ite. now part of the -.

Mr Madden yesterriav dis missed Government plans to mount a review of the asbestos reculations as ae. in sufficient response to the Om budsman's report. " 'Ve do net want a hclc-in-rl'.-v corner review conducted secret. In irv view, the w'-'.,; r thing should be aracred out -r-o the open, and an innuirv s!;.'. i!i be conducted m public," he sn.d. " I feel that if the asbestos industry is confident of 'be quality and the be rents or rs product and have ;.;;<ert the acmn thev should h ive done under the i:KJ reguiaUnqs. then thev shouid have nothing to fesr from such a public inquiry,'' Mr Madden added. ` Pretty wild ' Mr Jchr> Pickering, the Manrh?-:er ia'.wer v.r.o has re-r;se.nted most of tne Acre i.! . workers in damages suits. that the Cr.'r.udsir.an's renor. which did cot deal with C :n-> s Involvement, was " ?rc-:tv m.i.c..''

B MOORE VANCOUVER OPERATIONS 27APR76 RE: ALTERNATES FOR ASBESTOS This is in reference to your letter of 12APR76 requesting possible candidates for replacing asbestos tape for rack liners and separators. EL Tour unsuccessful attempts with fiberglass Materials leaves us with few alternatives - all of which are expensive. One material which may be of interest is Refrasil, a refractory silica in textile form. This material is available in many forms including tape and for special applications can be coated with Teflon and/or other selected materials. Refrasil is obtained through Materials Division of HITCO a subsidiary of Armco Steel Corp. The vest coast address is: Hitoo Materials Div., 1600 Vest 135th Street, Gardenia, California 92047. The contact at that location is Don Voldy at (213 ) 532-0670. Another possible candidate is ceramic fiber such as Carborundum* s Fiberfrax, Johns-Manville*b Cerafelt or Babcock and Wilcox's Kaovool. Information on these materials can be obtained through your local representatives. The big obstacle in asbestos replacements is accepting the fact that this switch may increase the initial cost tenfold or more. However, the asbestos-free materials which are compatible vith a specific application usually outperform asbestos with respect to service, durability, temperature, and resistance to chemical attack. If there are any questions on this matter, please feel free to contact me. M. J. CAPRIO KJCxgih cc: G. P. Nelson - Vancouver Wks. D. L. Werner - Vancouver Wks. D. M.

RE* ALTERNATES FOR ASBESTOS Refi Latter, R. P. Cartar to W. 3. Bovard, aa above. Wareh 30. 1976 Aa requested in the referenced letter, the following information ia given concerning the Vancouver Extrusion Rill's need for asbestos replacement eaterial. Vancouver, for years, has used an aebeatos paper tape for rack liners and separators on apscial surface finish extrusions in the T52 temper. While our use of asbestos paper tape has been small, it is another source of asbeetos fibers, which wa oust eliminate from the operation. The asbestos paper tape, which we have been using, is 1/16 inch thick by 3-1/2 inches wide and is used in approximately 30 inch and 90 inch lengths. Our requirement for an alternate material must have the following properties. 1. Withstand 550 F 2. Be non-staining to aluminum - 1.a., no outgaeing of binders. 3. Be non-abrasive to aluminum -- i.e., not produce burnish marks. 4. Not have irritant producing propertias euch as some lossly woven fiberglass aatarials have. 5. Coet and life of material -- number of times it can be reused directly related to cost of material. We have looked at many fibarglass astorials and coatings for aluminum spacers. To date, we have not found a satisfactory replacement. B. U. P100RE BUI: ms cc: Mr. C. P. Nelson, Vancouver Operations Or. W, 3. Bovard, Vancouver Operations r.r. 0. L.

To reduce the asbestos hazard, it is recommended that Marinite XL be substituted for Marinite 36 in all possible non-metal contact applications. As mentioned in the data letter, the Ceramic Section will evaluate Marinite XL for molten aluminum contact in the near future. *' ^d G. D/ SCHNITTGRUND GDS:lg cc: Associate/Assistant Directors Division/Department Managers A. S. Russell \ ALCOAO 000009605 FROM G. D. SCHNITTGRUND CERAMIC SECTION ALCOA TECHNICAL CENTER - B TO MEMORANDUM February 27, 1976 RE: DATA LETTER ______ JOHNS-MANVILLE'S NEW PRODUCT, MARINITE XL SUMMARY The captioned rigid insulating board was evaluated.as an asbestosfree replacement for Marinite 36. The Marinite XL sample exhibited lower bending strengths, greater loss on ignition; and higher values of linear change as a function of firing temperature than Marinite 36. However, up to 1000F XL can be used in a wide variety of industrial applications. INTRODUCTION Johns-Manville's Marinite XL can be handled, cut, and fabricated without environmental concerns for the asbestos dust hazard. XL is a calcium silicate bonded material currently selling for $78.94 per 48 x 96 x 1 inch thick board. It is also available in 1/.' and 3/4 inch thicknesses. This price is comparable to $74.50 per 1 inch board for Marinite 36. RESULTS AND DISCUSSION Table I lists ATC test results for Marinite 36 and XL. Despite XL's increased density (45 pcf) compared to that of Marinite 36 (36 pcf), XL's stregth as measured on a 1 x 1 x 10 inch sample in three-point bonding over a 9 inch span, is lower due to the absence of asbestos fibers. With increasing firing temperatures, the weight loss was dua to an initial loss of free water and organics burn-off and then the dehydroxylation of the calcium silicate hydrate binder. The loss of chemically combined water resulted in a strength decrease and linear shrinkage increase. The cold strength of Marinite XL began to increase after firing at 1400F and 1500F due to the development of a glassy phase. CONCLUSIONS AND RECOMMENDATIONS Marinite XL board is a reasonably priced asbestos-free product having adequate physical properties to perform as a substitute for Marinite 36 in most non-molten metal contact applications. r7 i-JALCQA ALCOAO 000009606 Memorandum February 27, 1976 Page 2 Data Letter - Johns-Manville1s New Product, Marinite XL In the near future XL will be evaluated for potential use in contact with molten aluminum.

No. EN-232033-BR Environmental Elements S.O. 370775 Ref: Installation of Asbestos Gasket Dear Mr. Meier: Thank you for your letter dated 28 January 1976 wherein you transmit Mr. Schell's letter to OSHA and their response. There is still one area of concern regarding the use of asbestos rope for gasketing material in this application. It is our understanding that the rope will be shipped in coil form. At the jobsite, the asbestos rope must be uncoiled, cut, and handled until such time as it is dipped into the red lead paint. Once the material has been dipped in the paint, all asbestos fibers should be securely bound and the material should then be safe to handle for installa tion . It is the preparation for painting which concerns us. How is it possible to uncoil, cut, and handle this asbestos rope without exposure to airborne concentrations of asbestos fibers? ' In preparing your comments in this regard, please feel free to call us and discuss any questions which arise. Very truly yours. '/ A-A /t/ R. C. COOK Staff Environmental RCC/rmb cc: _R_ R. T. G. H.

In short, these materials failed to provide adequate performance. The main reason as I understand it is that trough linings (melter-holder) must be made between transfers. Unless spare troughs are constructed, lined, properly dried and preheated (as is tiie practice at Massena, Warrick, Lafayette, etc.) performance will not be acceptable.
