Q What steps did you then take to gio forward with the elimination of asbestos? A We agreed to set up a series. We agreed to set up a research project to eliminate the use of these materials. Q What was the name of the project? Do you recall the name of the project? A 'i Q Elimination of asbestos. . Is there a file somewhere at NARCO that contains the written material pertaining to that project? A It is possible. Q Would that be located in the research department somewhere? . A If it exists. Q How often did your group meet? A Well, we didn't really .meet on that issue. We met at that time, I was.meeting.with staff on an every-two-or- three-month basis to review their work. . Q -All right. , A At that time we would have covered what was going on. Q Would there be records pertaining to what actually occurred in this research project to eliminate asbestos? A Yes. 88 Q Where would those records be? . A At the technical center. . Q You believe they are still there? A Yes. ................. - Q Have you reviewed them in preparation for your stimony? A Yes. MR. BARON:Counsel, do you have those records? MR. HEINTZMAN: I don't have them with me at this time, no. MR. BARON: I believe we requested those records in our request for production. MR. HEINTZMAN: I'm not sure you did^ You requested records which dealt with the potential- health hazards of asbestos. These records don't specifically go into the potential `health hazards, regarding the project to eliminate the asbestos from the products. I do not have those with me at this time. " ' " MR. BARON: We will request that you produce them posthaste, within the next week or so. Would that be possible? MR. HEINTZMAN:' Provided one thing, the 89 records also refer to other products and may contain some privileged communication. If we can work out an arrangement regarding -the confidentiality of these. As you know, many of their competitors are also defendants in this liigation. To produce records which might have technical information about other products, that can create a problem for us. We would have to protect.that privilege. MR. BARON: The only problem is they will have a hearing on this case on August 2nd. We feel that it is critical that we have those documents before August 2nd to review, to utilize those at the hearing.. So if you are going to insist on that, we need to do it very promptly. I hope that we would not have to have court intervention. _ MR. HEINTZMAN: fl don't think court : intervention is necessary. We will be in contact with Ron Heck and those fellows. Just to protect the confidentiality of that. MR. BARON: Fine. And we can bring it up at the Thursday meeting so we can be sure that we are going to get those documents. vtiytmp .nrnnv r. sccnpv?i'ri?c BY MR. BARON: 90 Q Were there problems involved with the removal of. asbestos from these products from an engineering point of., view? - ......... A place. Yes. That's why we used the material in the firs Q Okay. A They hadgood features. They gavegoodfeatures. Q NARCO hasbeen in business Has it not? A Yes. as NARCO since 1929? Q 1929? It has been producingspecialty productssince A I can't answer that. Q Well, certainly it was producing specialty products prior to 1963. Was it not?- . A I think so, yes. Q Now,- based on the list that had been given to me, the very first time that asbestos was ever used in any product manufactured by NARCO'was in' 1963? A That is what the records show. Q ` Was NARCO unable to manufacture commercially usable specialty products prior to 1963. A I don't know. I can't answer that. I wasn't here. - MAXINE JACOBY & ASSOCIATES brief review of MAJOR SPECIALTY PROJECTS OCTOBER 28. 1980 * 11.

Under this assignment irrc has also been carried out which involves the testing of a modified AIECCUN which was made at Farber for several special accounts. This mix hac been changed unilaterally by the Farber personnel and we had never really examined it in detail. Testing is completed with the exception of a chemical analysis. A data sheet will be issued to revise the properties of AEROCUN since the replacement of asbescos has resulted in slightly denser mix and a product with much less magnesia than before due to the removal c: the asbescos (a magnesium silicate). .IEF REVIEW OF MAJOR SPECIALTY PROJECTS Ma rcn 11, 197 5 EXHIBIT NO RA: ELIMINATION OF ASBESTOS FROM GUN MIXES OBJEC1 IVE: The use of asbestos as a gunning aid wn i c.i reduces the rebound in gunniny mixes is now looked on wi th disfavor because of er.vi r on- p mental rules and regulations limiting the quantity of asbestos in the air. Efforts are to be made to find a substitute for asbestos for our gun mixes; in particular our basic gun mixes will be worked on first. If successful here, we will then extend our technology toother products employing asbestos. The initial feeling was that a simple substitution of a less harmful fiber-type material could be used in place of asbesto anc retain the current gunning characteristics of tne various basic gun mixes. Fibers ordered and tested incluced milled fiberglass, soft wood flo^r, aloha cellulose, sisal fibers, cotton flock, fiber flax (cnopped), rayon and nylon flock. Each of tnese materials was added to NARMAG OH gun mix and each mix-in turn;was gunned cold without premoistening into panels for rebound and strength data. Hot gunning of the same mixes was also carried out where it was felt that the cold gunning showed some premise. Based on the results of our laboratory work, we would like to find a location where we could try a trial of NARMAG OH gun mix to verify the gunning characteristics found experimentally; this mix would include wood flour as a substitute for asbestos. Cold gunning of CM-18 indicates that wood flour will also be a good candidate for a substitute for asbestos in this product; therefore, we wouId" like to" secure a trial for this material, too. CRB-3^7 and P^-^bS have also been gunned cold with several binders, but at this time no acceptable alternative has been found. Work will continue on these products. Future work in this area will involve additional hot gunning trials using NARMAG OH gun mix as the base in order to evaluate several substitutes that in cold gunning did not look too good, but might do quite well in hot gunning. The idea of using fine shredded paper has some merit and will be explored. Finally, numerous large organic chemical companies will be canvassed inquiring aDout potential aoplication of some of t.neir pro duces as a substitute for asbestos with respect to o*-r needs Several products, suen asEMA, CMC and Methyl cellulose, fall in this category. After tnese avenues of approacn nave deer, tried witn respect to a direct suOstitutTon and nave not been successful, t.nen we will nave to go Pack to eacn mix anc see what is required to change tne mix in order to eliminate tne asbestos and yet obtain good gunning cnaracteristics. Hope fully, we can find a simple substitute although at tnis point it does not look too promising. BRIEF REVIEW OF MAJOR SPECIALTY PROJECTS SEPTEMBER 3. 1975 3.

RA-S35: ELIMINATION OF ASBESTOS FROM GUN MIXES -OBJECTIVE: The use of asbestos -as a gunning aid which reduces the rebound in gunning mixes is now looked on with disfavor because of environ mental rules ana regulations limiting the quantity of asbestos in the air. Efforts are to be made to find a substitute for asbestos for our gun mixes; in particular, our basic gun mixes will be worked on first. If successful here, we will then extend our technology to other products employing ashes tos. Fifteen mixes of PD-345 employing both physical and chemical addi tives were gunned since the last report period. One additive, ar. attapulgrte clay, gave rebound data very similar to that fc r asbestos. Based udct. these data, work orddrs were issued to h'orr.eisderf to manufacture PD-3^5 and CM-13`:Jich this addicive. JO-1005 ar.d '.70-1007, respectively. Or.e ar.d one-half tines as m.ucr. attarulgite was required in comparison to asbestos, but this amount is so small anyway (1.5 to 2.07.) that we don't anticip ar.v problems. The work orders were also .gunned and found -to excellent rebound, 17 ar.d ST1. respectively. The usual physic properties are also heir..; evaluated from, thes^e gunned panels. i- : r tu I VJ 8- - Ir. the meantime. a survey of the ocher ashestos-containing mixes has revealed only three additional produces sold during 1975 and 1976 that contain ashes cos --MARCOLITZ, NARCOGUN CO and AEROGUN. NARCCLITE is by far and away the nose accive produce of Che three and plans are being made to experiment with atcapulgite replacements in this product first, followed by the others. As physical results are completed on each produce, we will gradually switch to the new additive and carefully monitor ser vice reports on gunning and life. i BRJEF REVIEW Or MAJOR SPECIALTY PROJECTS ,?a::i;ary n, 1977 2.

Efforts are to be made to find a substitute for asbestos for our gun mixes; in particular, our basic gun mixes will be worked on first. If successful here, we will then extend our technology to other products employing asbestos. Work orders of PD-345 and CM-18 with an attapulgite clay sub stituted for asbestos have been completely evaluated; based on the good data obtained, new mix sheets for PD-345, PD-345A and CM-18 will be written and issued which show the use of this substitute. Future service results should be carefully monitored. NARWAG OH GUN MIX with the similar re placement has been made; the product cold guns all right. However, the Research Center gun became inoperative so further evaluation, including hoc gunning, will be delayed. Alumina-silica specialties mixes are also undergoing evaluation for feasibility of using the same substitute where necessary. NARCOLITE was studied in the laboratory and preliminary data suggests that attapulgite will work as an asbestos replacement, although a version with no asbestos or replacement also looked promising. Gunning properties of NARCOLITE with asbestos and attapulgite vs. NARCOLITE GUN will be compared next. Again, the gun repairs are holding up this work. These mixes are essentially our major sellhg products using asbestos so chances are very good that asbestos will be out of all specialties before long. A new mix chat affects this program was encountered by the uni lateral reinstatement by the Sales Department of SD-336. The attapulgite substitution was arbitrarily mad in this product formulation; Me. Union management was verbally informed of this decision on December 23. with paperwork to follow. BRIEF REVIEW OF MAJOR SPECIALTY PROJECTS MAY 17. 1977 IXF 13 Car') ' -14- 5.

Efforcs are to be made to find a substitute for asbestos for our gun nixes; in particular, our basic gun mixes will be worked on first. If suc cessful here, we will then extend our technology to other products employing asbestos. Laboratory work carried out under this project during the lasc several months 'can be itemized below: A. Conversion of NARMAG OH GLTN. Hot gunning will be required in order to complete testing on this product and this cannot be completed until city water is returned to the Research Center. B. Conversion of NARCOLITE. The use of Attagel 50 as a replacement for asbestos in this castable appears to be okay. A new mix sheet will be issued to the CurwensvlTle'plant reflecting this change. In the meantime, we will continue to look at possible less expensive ways of manufacturing NARCOLITE with, for example, the use of more plastic clays. We have found from our work that NARCOLITE and NARCOLITE GUN exhibit significantly different properties both as cast and gunned indicating a definite need for both products. C. Substitution of Attagel 50 in SD-336. Cold gunning of several varieti of this mix with Attagel 50 were examined; none of the materials ex hibited data sheec properties after drying at 230F or firing at 2000F for modulus of rupture, cold crushing or density. This matter needs to be discussed before we proceed with too many trials. ' The field reports will really tell us whether we have a problem. In summary, then, for Farber there are no mixes requiring asbestos. At Curwensville, we believe that with the conversion of NARCOLITE to Attagel 50 that there are no more specialties using ashestos* Womelsdorf needs only to have the NARMAG OH CUN completed and we will have all specialties mztde without the use of asbestos. BRIEF REVIEW OF MAJOR SPECIALTY PROJECTS DECEMBER 19. 1977 elimination of asbestos from cun mixes OBJECTIVE: The use of asbestos as a gunning aid which reduces Che rebound in gunning nixes is* now looked on with disfavor because of environmental rules and regula tions limiting the quantity of asbescos in the air.

The use of more plastic clays was one approach mentioned. Gleason clay, MLD clay and mixtures of the two proved to be detrimental to properties such as strength, plasticity or water retention. Several types of bentonites were investigated next, Hector and western. Again, strengths were affected and, also, imparted "thixotropic" tendencies to the body of the castable. Another look at western bentonite is felt in order. In addition a loss expensive grade of actanulgite will be checked out. One product we should incornorate in this program is AEROGUN If the tonnage is sufficient. Does Sales have thoughts on this?

A new mix that affects this program was encountered by the uni lateral reinstatement by the Sales Department of SD-336. The attapulgite substitution was arbitrarily made in this product formulation; Mt. Union management was verbally informed of this decision on December 23, with paperwork to follow. brief review of MAJOR SPECIALTY PROJECTS JULY 25. 1978 6.

Efforcs are to bo made to find a substitute for asbestos for our gun mixes; in particular, our basic gun mixes will be worked on firsc. If suc cessful here, we will then extend our technology to other products employing asbescos. Laboratory work carried out under this project during the last several months 'can be itemized below: A. Conversion of NARMAG OH GUN. Hot gunning will be required in order to complete testing on this product and this cannot be completed until city water is returned to the Research Center. B. Conversion of NARCOLITE. The use of Attagel 50 as a replacement for asbestos in this castable appears to be okay. A new mix sheet will be issued to the Curuensville .plant reflecting this change. In the meantime, we will continue to look at possible less expensive ways of manufacturing NARCOLITE with, for example, the use of more plastic clays. We have found from our work that NARCOLITE and NARCOLITE GUN exhibit significantly different properties both as cast and gunned indicating a definite need for both products. C. Substitution of Attagel 50 in SD-336. Cold gunning of several varieti of this mix with Attagel 50 were examined; none of the materials ex hibited data sheet properties after drying at 230F or firing at 2000F for modulus of rupture, cold crushing or density. This matter needs to be discussed before we proceed with too many trials. ` The field reports will really tell us whether we have a problem. In summary, then, for Farber there are no mixes requiring asbescos. At Curwensvillc, we believe that with the conversion of NAF.COLITE to Attagel 50 that there are no more specialties using asbestos. Vomelsdorf needs only to have the NARMAG Oil CUN completed and we will have all specialties m^de wlrhouc the use of asbescos. BRIEF REVIEW OF MAJOR SPECIALTY PROJECTS DECEMBER 19. 1977 I*P 13 CatO I 5- RA-8 35: ELIMINATION OF ASBESTOS FROM CUN MIXES OBJECTIVE: The U3e of asbescos as a gunning aid which reduces the rebound in gunning nixes is now looked on with disfavor because of environmental rules and regula tions Uniting the quantity of asbestos in the air.

I 8- In Che last report it was mentioned chat, although we had converted NARCOLITE to Actngel 50, we would continue to look for less expensive wavs of manufacturing NARCOLITE. The use of more plastic clays was one approach mentioned, Gleason clay, M&n clay and mixtures of the two proved to be detrimental to properties such as strength, plasticity or water retention. Several types of bentonites were investigated next, Hector and western. Again, strengths were affected and, also, Imparted "thixotropic" tendencies to the body of che castable. Another look at western bentonite is felt in order. In addition a less expensive grade of attapulgite will be checked out. One product we should incorporate in this program is AEROGUN if the tonnage is sufficient. Does Sales have thoughts on this? Your input is badlv needed. > j l BRIEF REVIEW OF MAJOR SPECIALTY PROJECTS JUNE 8. 1976 No RA: ELIMINATION OF ASBESTOS FROM GUN MIXES OBJECTIVE: The use of asbestos as a gunning aid which reduces the rebound in gunning mixes is now looked on with disfavor because of environ mental rules and regulations limiting the quantity of asbestos in the air.

Efforts are to be made to find a substitute for asbestos for our gun mixes; in particular, our basic gun mixes will be worked on first. If successful here, we will then extend our technology co other products employing asbes tos. Fifteen mixes of PD-345 employing both physical and chemical addi tives were gunned since the last report period. One additive, an attapulgice clay, gave rebound data very similar to that fer asbestos. Based upon these data, work orders were issued to Votr.eis derf to manufacture PD-3<i5 and CM-19 with this additive. WO-10G5 ar.d WO-1007, respectively. One ar.d one-half times as much attapuigite was required in comparison to asbestos, but this amount is" so small anyway (1.5 to 2.07.) that we don't anticipate ar.y prcbler.s. The work orders were also gunned and found .to have excellent rebound, 17 and. 37,, respectively. The usual physicuproperties are also heir.,; evaluated from, these gunned panels. i t r 8- - Ir. trhc2 meantime, a survey or the ocher asbestos-containing mixes has revealed only three additional produces sold during 1975 and 19 76 chat contain asbestos--NARCOLITZ, NARCOGUN CO and AEROGUN. NARCCLITE is by far and away the nose active product of the three and plans are being made to experiment with attapulgite replacements in this product first, followed by the others. As physical results arc completed on each product, ve will gradually switch to the new additive and carefully monitor ser vice reports on gunning and life. .i BRIEF REVIEW OF MAJOR SPECIALTY PROJECTS DECEMBER 16. 1975 tx v /3 C t 4* l 3.

NARCOGUN PD-345 has been chosen as the mix to use because it has shown less tendency to be pro duced with anything but asbestos. Additions to be tested include cellulose gums, hydroxyethyl cellulose products, xanthun gums, micas and several types of fibers. So far, eleven batches have been produced and will be gunned shortly. Rebound, cold strength and bulk density will be principal properties of interest. If successful here, the additive will, of course, be tried in our other gun - mixes- -where asbestos is used. BRIEF REVIEW OF MAJOR SPECIALTY PROJECTS SEPTEMBER 3. 1975 No RA: ELIMINATION OF ASBESTOS FROM GUN MIXES OBJECTIVE: The use of asbestos as a gunning aid which reduces the rebound in gunning mixes is now looked on with disfavor because of environ mental rules and regulations limiting the -5- quanticy of asbescos in the air.

NORA; ELIMINATION OF ASBESTOS FROM GUN MIXES OBJECTIVE: The use of asbescos as a gunning aid wn i cn reduces Che reDOund in gunning mixes is now looked or. wi tn disfavor because of er.vi ron- p mental rules and regulations limiting the quantity of asbestos in the air. Efforts are to be made to find a substitute for asbestos for our gun mixes; in particular our basic gun mixes will be'workea on first. If successful here, we will then extend our technology toother products employing asbestos. The initial feeling was that a simple substitution of a less harmful fiber-type material could be used in place of asbesto anc retain tne current gunning characteristics of tne various basic gun mixes. Fibers ordered and tested incluced milled fiberglass, soft wood flo~r, aloha cellulose, sisal fibers, cotton flock, fiber flax (cnopped), rayon and nylon flock. Each of tnese materials was added to NARMAG OH gun mix and each miXjin turn^was gunned cold without premoistening into panels for rebound and strength data. Hot gunning of the same mixes was also carried out where it was felt that the cold gunning showed some premise. 6ased on the results of our laboratory work, we would like to find a location where we could try a trial of NARMAG OH gun mix to verify the gunning characteristics found experimentally; this mix would include wood flojr as a substitute for asbestos. Cold gunning of CM-18 indicates that wood flour will also be a _gocd candidate for a substitute for asbestos in this product; therefore, we would like to secure a trial for this material, too. CRB-347 and PD-345 have also been gunned cold with several binders, but at this time no acceptable alternative has been found. Work will continue on these products. Future work in this area will involve additional hot gunning trials using NARMAG OH gun mix as the base in-order to evaluate several substitutes that in cold gunning did not look too good, but might do quite well in hot gunning. The idea of using fine shredded paper has some merit and will be explorea. Finally, numerous large organic cr.err.ical companies will be canvassed inquiring about potential aoplication of some of t.neir pro ducts as a substitute for asbestos with respect to our needs Several products, such asEMA, CMC ana Methyl cellulose, fall in this category. After tnese avenues of approacn nave Deer, tried wi tn respect to a direct substitution and nave not been successful, tnen we will na-.e to go Pack to eacn mix anc see what is required to chance tne mix in order to eliminate tne asbestos and yet obtain gooc gunning cnaracteristics. Hope fully, we can find a simple substitute although at tnis point it does not look too promising.
