7 rNO. 91-891-B LAWRENCE SMITH and VERA flAE SMITH; CHESTER KERSHHAN and RUBIE KERSHHAN; JERRY WILLIAMS; and THOMAS STALLCUP, Plaintiffs, vs. ARMSTRONG WORLD INDUSTRIES, INC., et al., Defendants. ) ) ) ) ) ) ) ) ) ) ) ) ) ) IN THE DISTRICT COURT OF DALLAS COUNTY, TEXAS 44TH JUDICIAL DISTRICT W.R. GRACE AND CO. - CONN'S SUPPLEMENTAL ANSWERS AND OBJECTIONS TO PLAINTIFFS' FIRST SET OF INTERROGATORIES GENERAL OBJECTIONS The following answers are based upon facts known or believed by W. R. Grace & Co. - Conn., formerly known as W. R. Grace & Co., ("Grace-Conn") at the time of answering these interrogatories. Much of the information is sought from many years ago and is, therefore, difficult or impossible to reconstruct or retrieve. Grace-Conn, therefore, reserves the right to amend these answers as and if new or better information becomes available to it or if errors are discovered. In Exhibit D to their answers to defendants' master set of discovery requests, plaintiffs Lawrence Smith and Vera Mae Smith allege exposure of Lawrence Smith ("plaintiff Smith") to "Zonolite Acoustical Plasters" and "Zonolite Monokote" at "Numerous schools, hospitals and skyscrapers in Dallas" from 1946-1952 and 1955-1989 and to "Mono-kcte" at the "State Capitol Bldg in Austin" in 1962. Plaintiffs further allege exposure of plaintiff Smith to "Zonolite Vermiculite" at a "Powerhouse on Haskell" in Dallas from 1952-1955 and at the "Brookhollow Country Club" in Dallas in 1963. Plaintiff Smith identified "Monokote Zonolite Fireproofing" in the "OCF Picture Book." With regard to the allegation of exposure of plaintiff Smith to "Zonolite Vermiculite", Grace-Conn states that vermiculite is the name of a mineral, not a product. Therefore the allegation of exposure of plaintiff Smith to "Zonolite Vermiculite" is vague and ambiguous. With regard to the various allegations cf exposure of plaintiff Smith to "Monokote", Grace-Conn states that beginning in 1958, it or the Zonolite Company, the assets of which Grace-Conn did not acquire until 1963, manufactured four products with the word ' "Mono-Kcte"- in their names: Zonolite Mcno-Kote (MK-1), Zonolite Mono-Kote (MK-3), Zonolite Mono-Kote (MK-4), and Zonolite MonoKote (MK-5). Zonolite Mono-Kote (MK-4) and Zonolite Mono-Kote (MK-5) have never contained commercial asbestos but do contain vermiculite. Products which contain vermicuite may contain trace amounts of asbestiform tremolite as a contaminant. Grace-Conn therefore-limits its answers with regard to plaintiff Smith to Zonolite Acoustical Plaster, Zonolite Mono-Kote (MK-1), Zonolite Mono-Kote (MK-3), Zonolite Mono-Kote (MK-4), and Zonolite MonoKote (MK-5) and to the activities of its Construction Products Division ("CPD") associated with the manufacture and sale of same in the United States during the relevant time period. In Exhibit D to their answers to defendants' master set of discovery requests, plaintiffs Chester Kershman and Rubie Kershman allege exposure of Chester Kershman ("plaintiff Kershman") to "Zonolite Acoustical Plasters" and "Zonolite Monokote" at various commercial buildings, hospitals, and schools in Dallas from 1951-1957, 1959-1967, 1972, 1976-1983, and 19851989 and to "Zonolite Monokote Fireproofing" at "Several Commercial Bldgs including the airport" in Dallas in 1965, 19691970, and 1972. Further, plaintiff Kershman identified "Zonolite Plaster" and "Zonolite Monokote" in the "OCF Picture Book." With regard to the various allegations of exposure of plaintiff Kershman to "Monokote", Grace-Conn states that beginning in 1958, it or the Zonolite Company, the assets of which Grace-Conn did not acquire until 1963, manufactured four products with the word "Mono-Kote" in their names: Zonolite Mono-Kote (MK-1), Zonolite Mono-Kote (MK-3), Zonolite Mono-Kote (MK-4), and Zonolite MonoKote (MK-5).. With regard to the allegation of exposure of plaintiff Kershman to "Zonolite Plaster", Grace-Conn states that, upon information and belief, the product to which plaintiff Kershman intended to refer was Zonolite Plaster Aggregate. Zonolite Mono-Kote (MK-4), Zonolite Mono-Kote (MK-5) and Zonolite Plaster Aggregate have never contained commercial asbestos but do contain vermiculite. Products which contain vermicuite may contain trace amounts of asbestiform tremolite as a contaminant. Grace-Conn therefore limits its answers with regard to plaintiff Kershman to Zonolite Acoustical Plaster, Zonolite Mono-Kote (MK1), Zonolite Mono-Kote (MK-3), Zonolite Mono-Kote (MK-4), Zonolite Mono-Kote (MK-5), and Zonolite Plaster Aggregate and to the activities of its Construction Products Division ("CPD") associated with the manufacture and sale of same in the United States during the relevant time period. In Exhibit D to their answers to defendants' master set of discovery requests, plaintiff Thomas Stallcup ("plaintiff Stallcup") alleges -exposure to "W.R. Grace High Temperature Insulating Cements" at "Wichita Falls" in Red River, NM from 1946-1948 and at."Wichita General Hospital" in Dallas from 19511952. Plaintiff Stallcup further alleges exposure to "W.R. Grace Zonolite Acoustical Plaster" at "Several Schools and Commercial Buildings including Memorial Auditorium" at Grand Prairie, TX in 1949 and 1955-1959 and at Fort Worth Nat'l Bank in Fort Worth in 1952. Plaintiff Stallcup further alleges exposure to "Zonolite Vermiculite" at "Thomas Jefferson High School" in Tyler, TX in 1955 and to "Zonolite Plasters" at "Southland Center" in LaJolla, CA from 1958-1962. With regard to plaintiff Stallcup's 3 allegation of exposure to "Zonolite Vermiculite", Grace-Conn states that vermiculite is the name of a mineral and not a product. Therefore, plaintiff Stallcup's allegation of exposure to "Zonolite Vermiculite" is vague and ambiguous. With regard to plaintiff-Stallcup's allegation of exposure to "Zonolite Plasters", Grace-Conn states that during the relevant time period the Zonolite Company manufactured the following plaster products: Econo-White 65 and Econo-White 70, Zono-Coustic 2 and ZonoCoustic Z, Zonolite Acoustical Plaster, Zonolite Finish Coat (Decorator's White), Zonolite Finish Coat (Decorator's White)(Extra Hard), Zonolite Spra-Tex (Regular), Zonolite SpraTex (Extra Hard), Z-Tex, and Plaster Aggregate. Plaster Aggregate has never contained commercial asbestos but does contain vermiculite. Products which contain vermicuite may contain trace amounts of asbestiform tremolite as a contaminant. Grace-Conn therefore limits its answers with regard to plaintiff Stallcup to High Temperature Insulating Cement, Econo-White 65 and Econo-White 70, Zono-Coustic 2 and Zono-Coustic Z, Zonolite Acoustical Plaster, Zonolite Finish Coat (Decorator's White), Zonolite Finish Coat (Decorator's WhiteMExtra Hard), Zonolite Spra-Tex (Regular), Zonolite Spra-Tex (Extra Hard), Z-Tex, and Plaster Aggregate and to the activities of its Construction Products Division ("CPD" ) associated with the manufacture and sale of same in the United States during the relevant time period. Plaintiff Jerry Williams ("plaintiff Williams") does not allege exposure to any product manufactured by Grace-Conn at any location at any time. It is unreasonable and unduly burdensome to require Grace-Conn to make assumptions concerning relevant products when plaintiff Williams has provided no evidence that he was ever exposed to a Grace-Conn product. Therefore, with regard to plaintiff Williams, Grace-Conn objects to answering certain of these interrogatories on the grounds that they are irrelevant, immaterial, overly broad, unduly burdensome, and not reasonably calculated to_ lead to the discovery of admissible evidence because plaintiff Williams has not provided any evidence that he was ever exposed to any product manufactured by Grace-Conn at any location at any time. Grace-Conn expressly denies that the information contained herein is relevant and reserves the right to object to the admissibility of all or part of any answer on this basis. To the extent that these interrogatories call for information beyond the limitations stated above, an objection is made thereto as being irrelevant, immaterial, overly broad, unduly burdensome, and/or not reasonably calculated to lead to the discovery of admissible evidence and the answers thereto are privileged and/or protected. Grace-Conn further objects to these interrogatories insofar as they seek production of any information constituting a trade secret, confidential financial data or other confidential research, development or commercial information. Grace-Conn further objects to these interrogatories insofar as they seek information which is subject to the attorney-client privilege, which evidences or constitutes attorney work product, or which is- otherwise not discoverable under the provisions of the Texas Rules of Civil Procedure. 4 INTERROGATORIES INTERROGATORY 1 Please identify by trade or brand name and serial number each asbestos-containing product manufactured, sold and/or distributed by Defendant.

With regard to plaintiff Williams, Grace-Conn states see the General Objections interposed above. INTERROGATORY 2 Prior to releasing the products listed in Interrogatory No. to the public for sale, were any tests conducted on same by Defendant or Defendant's agents and/or consultants to determine any potential health impacts involved in the use of or exposure to any of the products listed in answer to Interrogatory No. 1? 1 If so, please state: (a) The name, address, and job classification of each individual who conducted such tests; (b) The dates -of each such test, if any; and (c) The results of such tests. ANSWER 2 Subject to the General Objection interposed above, and with regard to plaintiffs Smith, Kershman, and Stallcup, Grace-Conn states not to its knowledge. With regard to plaintiff Williams, Grace-Conn states see tHe General Objections interposed above. 6 INTERROGATORY 3 Were any design, marketing, labeling and/or packaging changes made as a result of such tests? If so, please state: (a) The nature and date of the change made; (b) The name, address, and job classification of each person in charge of making a change. ANSWER 3 Not applicable. INTERROGATORY 4 After releasing the products listed in answer to Interrogatory No. 1 to the public, were any tests conducted thereon by or for Defendant to determine potential health impacts involved in the use of or exposure to any of the products identified in answer to Interrogatory No. 1? If so, please state: (a) The name, address, and job classification of each person conducting said tests; and (b) The results and date of said tests. ANSWER 4 Subject to the General Objections interposed above, and with regard to plaintiffs Smith, Kershman, and Stallcup, Grace-Conn states not to its knowledge. With regard to plaintiff Williams, Grace-Conn states see the General Objections interposed above. INTERROGATORY 5 Has Defendant, at any time, published and/or distributed any brochures, pamphlets, packagings or other written materials of any kind or character that contain any warnings, cautions, caveats, instructions or directions concerning the possibility of injury or health impacts resulting from the use of or exposure to any of the products listed in Interrogatory No. 1? If so, for each such product, if any, please state: (a) The wording of each such warning; (b) The method used to distribute the warning to persons 'who are likely to use and/cr be exposed to the products; 7 (c) The date each such warning was issued; and (d) Any tests, research data, studies and publications _relied upon in whole or in part in the decision to release such warning, if any. ANSWER 5 Grace-Conn objects to this interrogatory on the grounds that it is overly broad, unduly burdensome, irrelevant, immaterial and not reasonably calculated to lead to the discovery of admissible evidence as it is not limited as to caution, time periods, locations, etc. Grace-Conn further objects to this interrogatory on the grounds that it is vague and ambiguous in that terms such as "warning" are undefined and subject to various interpretations. Grace-Conn further objects to this interrogatory on the grounds that it improperly implies that Grace-Conn's products presented a hazard to users. Subject to these objections and to the General Objections interposed above, and with regard to plaintiffs Smith, Kershman, and Stallcup, Grace-Conn states that no warnings were placed on the packaging of its products that contained commercial asbestos nor were any warnings placed directly on any of its products. Grace-Conn further states that it had sales brochures for most of its products . Further answering with regard to plaintiffs Smith and Kershman, Grace-Conn states that the 1970 Grace-Conn brochure published in Sweet's Catalog of 1971 contained the following paragraphs: "POLLUTION AND HEALTH: Because of the constantly changing conditions involving fireproofing and its relation to pollution and health, we recommend that you contact your Zonolite sales office for the latest data on these subjects. Recent tests at Underwriters Laboratories, Inc. have provided some fire-ratings on an asbestos-free formula Mono-Kote. Other tests and ratings will fellow." "Existing formulations of Mono-Kote contain minimal amounts of asbestos which are locked in during the mixing process. Mono-Kote is wet mixed, pumped and sprayed, and hardens to a cementitious mass. Jobsite tests show air fiber counts well below occupational Threshold Limit Values proposed by government bodies." In addition, with regard to plaintiffs Smith, Kershman, and Stallcup, Grace-Conn states with regard to its vermiculite products that beginning in 1976, in the form of Material Safety Data Sheets it notified customers of the need to wear NIOSH/I1ESAapproved respirators when threshold limit values were exceeded. Also starting in 1976 or 1977, Grace-Conn affixed a caution regarding nuisance dust tc the packaging of its vermiculite products. This caution read: 8 CAUTION AVOID CREATING DUST BREATHING DUST MAY BE HARMFUL TO YOUR HEALTH _USE WITH ADEQUATE VENTILATION OR WITH RESPIRATORY PROTECTION Relevant, non-privileged and non-trade secret documents containing information responsive to this interrogatory will be made available to the plaintiffs in Boston, Massachusetts at a mutually agreeable time. With regard to plaintiff Williams, Grace-Conn states see the General Objections interposed above. INTERROGATORY 6 Did Defendant receive notice prior to 1972 that any person was claiming injury, including but not limited to workers' compensation claims, as a result of using and/or being exposed to any asbestos-containing products that were manufactured, distributed and/or sold by Defendant, Defendant's predecessor or any of Defendant's subsidiary companies? If so, please state: (a) The name and address of each claimant; (b) The date of notice of each claim; (c) A description of the claim; (d) The type of injuries allegedly sustained; (e) The style, court number and/or claim number of each such claim; and (f) The disposition of such claim. ANSWER 6 Grace-Conn objects to this interrogatory on the grounds that none of the plaintiffs were employees of Grace-Conn and, therefore, this interrogatory is irrelevant, immaterial and seeks information not reasonably calculated to lead to the discovery of admissible evidence". In addition, Grace-Conn objects on the grounds that the information sought regarding other personal injury claims are a matter of public record equally available to plaintiffs as to Grace-Conn. Subject to these objections and to the General Objections interposed above and with regard to plaintiffs Smith, Kershman, and Stallcup, Grace-Conn states that in 1955 an employee, possibly named Weismantie, of the California Zonolite Company, in its Sacramento, California plant, filed a claim with the State Compensation Insurance Fund in California for disability allegedly because of asbsstosis. No further 9 information is known about this possible claim.

INTERROGATORY 7 Please state whether or not the Defendant has ever conducted any tests in the field (i.e., where Defendant's asbestoscontaining products were actually being used) to determine the concentration of asbestos dust and fibers generated from the use, preparation, application and/or removal of any of the asbestos products listed in answer to Interrogatory No. 1. If so, please identify: (a) The date, place and nature of each and every test; (b) The particular product to which each test applied; and (c) The results of each test with particular reference to the concentrations of asbestos dust and fibers per cubic centimeter of air found to which the person was exposed. 12 ANSWER 7 Subject to the General Objections interposed above and with regard to plaintiffs Smith and Kershman, Grace-Conn states the following concerning tests relating to the spraying of Mono-Kote fireproofing (MK-3): 1. Tabershaw-Cooper Associates conducted air sampling in July, 1970, at three buildings in San Francisco. Fiber concentrations in all spray areas, except for one reading, were found to be below the then existing Threshold Limit Value for occupational exposures. 2. In 1970, the Werby Laboratory reported on air samples taken by Grace-Conn employees during Mono-Kote spraying operations in Chicago, Illinois, Los Angeles, California, Omaha, Nebraska and Bethpage, New York.

With regard to plaintiff Stall cup, and subject to the General Objectins interposed above, Grace-Conn states not to its knowledge. With regard to plaintiff Williams, Grace-Conn states see the General Objections interposed above. 14 INTERROGATORY 8 'Has Defendant ever sold any asbestos-containing materials for use in any place outside the continental United States of America (and Hawaii) without affixing to the product a caution or warning label which discussed the health impacts caused by asbestos? If so, answer the following questions: (a) Identify these products by trade name and describe the percentage of asbestos content of same; (b) Identify the years said products were sold; and (cj Identify the buyers of said products and the nations or states in which said products were intended to be delivered for use. ANSWER 8 Grace-Conn objects to this interrogatory on the grounds that it is overly broad, unduly burdensome, irrelevant, immaterial, and net reasonably calculated to lead to the discovery of admissible evidence. INTERROGATORY 9 Did Defendant before 1973 ever conduct studies or tests of the concentration of dust generated in any of its asbestos products manufacturing plants? If so, (a; Identify the dates of every such dust count studies taken; (b) Identify every plant at which such dust count studies were taken; and (c) Please produce all documents which show any dust count studies or tests taken at any of Defendant's asbestos manufacturing plant(s). ANSWER 9 Grace-Conn obj-ects to this interrogatory on the grounds that none of the plaintiffs were employees of Grace-Conn and, therefore, this-interrogatory is irrelevant, immaterial and seeks information not reasonably calculated to lead to the discovery of admissible evidence. Subject to this objection and to the General Objections interposed above and with regard to plaintiffs Smith, Kershman, and Stallcup, Grace-Conn states that beginning in approximately 1965, air sampling as a part of general health and safety reviews were performed by Grace-Conn personnel at its Libby, Montana mine and mill. Grace-Conn further states that since approximately 1969 periodic dust studies as part of general health and safety reviews have been performed by Grace-Conn personnel at its manufacturing facilities on a routine basis. Relevant, non-privileged and non-trade secret documents containing information responsive to this interrogatory will be made available to the plaintiffs in Boston, Massachusetts at a mutually convenient time. With regard to plaintiff Williams, Grace-Conn states see the General Objections interposed above.

Lovick, Libby DATE: February 17, 1970 SUBJECT: Kenbrane Filter Saasllne When 1 was in Libby, 1 had a chance to go over the nembrane filter nethod of sampling with Lou Krupp, but did no: have the time to discuss this with J. D. Riggleman. In this letter, I will try to review it briefly for both of you, and any details cnitted can be obtained from the instruction book that is enclosed. This is a tenporary reasure, as you know, and as soon as soceone is hired to carry on this and other functions at Libby, both Rex Saith and Walt Baker will be freed of this task. I have giver, both Rex and Walt a copy of the instructions, but neither got copies of the first part of the sanual that deals with the harards associated with asbestos. Both cen were given a short J training session on the principles involved in the use of the sampling equip ment, and 1 feel will be capable of carrying cut this collateral duty that has been assigned to them. 1 have asked that they both show the sampled monitor and data sheet to you hefcre it is sent to the laboratory here in Boston. In the membrane filter method of sampling, ve are only concerning ourselves with the collection and reading of treoolite and asbestos fibers that are known to be in Libby ore. Through impingere tests that W. Nordin has con ducted we know that the particulate level in the dry mill can be controlled vitbin allowable threshold limit values for total dust. What we don't know is the level of fibers and if we are below the threshold limit value established by the U. S. Public Eealth (12 microns per cc_longer than 5 microns in length). Johns Manville and~Crsce "have ~estaoTishfed a value of S' fibers per cc. Sampling is a relatively simple procedure and will in no way interfere with_tne movement of an operator in" performing his normal duties. A vacuum pump is attached to a man's belt and connected, by means of a rubber tube, to a monitor fastened to the operator's' skixt collar. The monitor is positioned in the breathing rone of a person and the rate of flow through the vacuum pump at the normal respira tory rate of two leaders per minute. The person being sampled should conduct his normal duties and in no way should deviate froa them to be either in a clean or dusty environment. As an example, on February 3 we sampled the top floor dry mill operator for ninty minutes, and during this period of time he made one com plete round of the upper floors and dryer area, and the remainder of the time was spent in the operators roon on the first level. It is not necessary for either Walt or Rex to follow the cen around all the time, but every thirty minutes they should check the vacuum pump to see that it is operating properly and observe conditions in the area being sampled so that the sampling data sheet can be filled out with all pertinent information.

Sterrett SIrroco Fan and Montana State Board of Health;Inspections Dear Floyd: We have never had an opinion expressed regarding the SIrroco fan froia Mr. Ben \fitdhs. State Beard Engineer. Mr. Wake has only been concerned with the inside atmosphere ot the ni 11. This, of course, makes him Interested in any source of dust which contributes to the pollution of the mill atmosphere but to our knowledge his observations and comments have been on Internal sources. I suppose that it is possible that any possible pollution from the fan could have escaped his observation. That is, for conditions to have been favorable in every respect at each time of his Infrequent visits. Cur allowable limit as per the State Board is 20 million particles per cubic foot. We-have set our cvn at 10 m ppcf anc the insurance people are trying to dictate 5 m ppcf. Now, there are-times when all the conditions are such that seme pollution does occur from the fan discharge. These times are in frequent and a small percentage of the total, time. Also, there is real doubt as to whether any pollution from the far. curing ttese times actually increases the cust count beyond the allowable limits. However, we must admit that It can and does occur at these Infrequent intervals. We have not been able to detect any crastic Increase in dust count during these times. The allowable limit Is In effect at all times. Therefore, 1 believe that Jt wculd be natural to expect that Mr. Wake In his capacity would be In favor of any project which would tend to remove any potential source of pollution but would no: demand that It be done as long as the dust counts were sat Isfactory. In other words, I believe that he would leave the method on how to get the required results to us but expects us to get them. He probably wculd give js an opinion if asked but seriously doubt that he c-uld give us anything except to be in favor of moving the fan. Moving the fan most certainly will not be detrimental to the dust situation. Just hew much benefit will be derived is the unknown question. At times It will help a lot, especially in the outside area, while at other times It probably will not help enough to make any difference. It will not bring the dust count down to 5 m ppcf. Any ary mill extension to the east, etc. will require moving the fan. I don't believe that Mr. Parks is going to relent on the subject and will continue to insist. Could our failure tc comply with his recomnendatIons ever be used to escape responsibility or liability on their part in the future?
