GO -'00,'- Date MARCH 4, 1976 Ref: Memo Jensen to Gasper 2/27/76 (15G-07) Attached is a copy of the current company guide regarding use of asbestos products. The primary basis of our present position is a 1972 NIOSH report of a government survey of exposure in asbestos fabrication. A total of 44 workers were monitored while doing various operations in the fabrication of asbestos products. Vie can predict exposure results from thi3 survey, however, the OCHA standard requires that vo confirm by routine air monitoring ns specified In item 3 o1' our guide. A recent legal interpretat ion 'has also confirmed medical testing requirement employees exposed under it em 3 of our guide. The medical surveillance is required regardless of the asbestos level found in air monitoring under guid' item 3. for Compliance with item 1 and 2 will continue to eliminate any necessity for air or medical monitoring.

ASBESTOS PRODUCTS | This letter to cover one customer and one subject only. File Ho. or Ref. Date ens 6t>-5 15G.07 2-27-76 In response to your letter of Februalry 11, 1976 outlining the OSHA requirements on the use and application of asbestos which is becoming a critical situation for B&W I wish to advise as follows: 1. The Material Ordering standard 4A2-2A1-4A44 under "GASKETS" presently states that gaskets are to be ordered purchased to size for economical reasons. However, this standard does permit cutting of gaskets from gasket sheet stock in special cases. In my opinion, the standard should be revised to insist on purchased gaskets and the sheet material should be removed from folioed stock. 2. It is my understanding that purchased sheet gaskets used in our shops as received rflSdffhe (J)HA requirements ancf hd" 't'hamye in our ordering procedure is required if we use the purchased gaskets without change. By copy, 0. J.^Fisher is requested to advise if this is not correct. 3. Ther~ rrn nr (FP|7) gM. S/0 W/S specifying gaskets to be cut in B&W shops. 4. TLT fans and RAH do require gaskets to be cut in the shop. By copy, will M. S. Merritt & R. B. Rizor review their orders for gaskets to be cut from sheet gasket material. 5. FPG Components Engineering have been in contact with Purchasing to determine possible substitute materials but to date, have been unable to establish replacement materials. 6. Asbestos packing is currently being specified in lineal feet (LF) by Engineering & Graphics and the exact lengths required have not been established. If packing can no longer be cut ir. the shops, it willjbe,,a .considerable task to establish cut lengths required. The 4A2-2A1-4A44 under "PACKING" will need to be revised to indicate revised instructions to Engineering & Graphics. 7.

S I&M Standards Central Management Purchasing The availability of asbestos products, plus OSHA requirements on the use and application of asbestos is becoming a critical situation for B&W. Attached is a letter dated February 4,1976, from J.A. Smith (Barberton Material Malager) and letter of October 24,1975 from M.L. Ruthranff (Mgr., Corporate Safety & Health). These letters begin to point out some of the problems we are facing, not only in the Barberton Works, but for all our Works' inventory. It is recommended that Engineering and Purchasing coordinate your expertise and recommend acceptable material to replace harmful asbestos type products within PGG. If replacement material is not acceptable or available, then pre-cut asbestos type materials would have to be established. If we can supply any data to aia in this review, please contact us.

Sellers G. R. Wagner W. F. Wieland The following conclusions are drawn from our recent inquiry on the above-subject. (1) You should specify resin treated or 'Vet-brushed" asbestos fabric when purchasing materials containing asbestos. (2) Cutting or buffing asbestos material should not be practiced in our shops. If such procedures are found necessary, alternate purchase of specific form and sizes should be considered. It is best to have the vendor do all the fabricating and working of asbestos material. (3) We should run routine air monitoring where any procedure or operation does not comply with Items Nc. 1 and No. 2. (The asbestos standard will soon drop to 2 fibers/cc and there is a --oposal to reduce it further to fiber/cc.) (4) Materials containing asbestos should be used only where other materials are not available. (5) NIOSH evaluation of asbestos vendors' plants does indicate that we should be in full compliance in using asbestos materials per the above guidelines. We do not recommend that asbestos monitoring be instituted other than indicated under Item No. 3. MLR/mg bcc: H. E. Auricchio M.

E. SINGLErON - CORPORATE SAFETY AND HEALTH Sub j. i SUMMARY AND CONCLUSIONS OF ASBESTOS SAMPLING File No. or Ref. GO 6060- Gate SEPTEMBER 8, 1976 GENERAL The attached table summarizes asbestos sampling to date. A survey was conducted to determine the various forms and uses of asbestos materials within the Company. Representative air samples were then collected during typical operations by using MSA Gravimetric Dust Sampling equipment and open-face AA filter cassettes supplied by Clayton Environmental Consultants. The Clayton laboratory then analyzed the samples using the standard NIOSH method. ANALYTICAL METHOD The Clayton laboratory uses Phase Contrast Illumination Microscopy as specified by NIOSH. A given sample is transformed into a transparent gel and a pi6 shaped wedge is cut from it. Using 400 power magnification a minimum of 20 microscope fields and a maximum of 100 fields are scrutinized, depending upon the detection of at least 100 fibers. However, 100 fields is not exceeded even if fewer than 100 fibers are viewed. Results are reported as asbestiform fibers because the method does not allow for ,trict identification that the fibers being counted are actually asbestos. That can only be determined from separate analysis of bulk samples. To qualify as asbestiform, fibers must be greater than 5 micrometers in length and have an aspect ratio of 3 to 1 or greater. Where no asbestiform fibers are seen in 100 microscope fields, that is reported as ( I?O0 fibers per total filter. The resulting concentration is shown with < symbol and a value dictated by volume. Where one asbestiform fiber is seen in 100 fields, that is reported as 2900 fibers per total filter. The resulting concentration value is likewise dictated by th9 volume sampled. DISCUSSION OF RESULTS The table footnotes show the two current Threshold Limit Values and the proposed value. The ceiling value, according to NIOSH, is the ^peak allowable concentra tion as determined by a minimum sampling time of fifteen minutes. 0SHA3 current standard includes no mention of this minimum sampling time. The Time-Weighted Average exposure limits are for an 8-hour work day. These can either be determined by sampling for 8 hours, or sampling for a representative time period and cal culating based upon the length of time the exposure to asbestos is present. The last column of the table contains footnote codes which relate the test results to these exposure limits. SUMMARY AND CONCLUSIONS OF ASBESTOS SAMPLING PAGE 2 If the proposed TLV (- fiber per cc of air, 8-hour TWA) is adopted, then many of the samples collected represent conditions of possible "overexposure". All of the test results shown in the table are for representative sampling times. The footnotes also refer to certain key samples for which the 8-hour time weighted average exposures were calculated and compared with the TLV * s. ASBESTOS PRODUCTS The asbestos products used in the sampling were the following: 1. Treated and untreated cloth 2. Pre-cut gaskets and gasket materials 3. Rope and ribbon packing materials 4. Millboard 5. Coated weld rods 6. Gloves Interviews with 2 asbestos product manufacturers revealed the following: 1. Untreated cloth products should bear a health hazard label. 2. Treated fabrics have greater abrasion resistance, as much as 79$ greater than untreated. 3. Treated fabrics exhibit as much as 75$ reduction of airborne fibers in tests comparing them to untreated. 4. ASTM grade classifications for asbestos textiles are a3 follows: Grade Asbestos Content bv Weight Temp. Limit Commercial Underwriters A AA AAA AAAA 75$ to 80$ 80$ to 85$ 85$ to 90$ 90$ to 95$ 95$ to 99$ 99$ to 100$ 400F. 450F. 550PF. eocf?. 750PF. 900F. Where asbestos content is less than 100$, binder materials such as cotton, neoprene, brass wire, etc., are woven with the asbestos to give it strength. Fiber-capturing applications such as wet-brushing, resin-bonding, etc., are designed to be effective at least to he above temperature limits for general performance of the cloth. When these limits are exceeded, the binders and the "health" treatments are burned out. The resulting material has little mechanical strength and readily frees fiberB into the air. Some typical B&W service tempera tures are as follows: 1. Opposite surface of steel under preheat = 500F. 2. Chimney effect of heated air (from drums, nozzles, etc.) = 700F. 3 Direct flame impingement from a natural gas preheat torch = 2000F. SUMMARY AM) CONCLUSIONS OF ASBESTOS SAMPLING PAGE 3 No "health" treatments are rendered to millboard products and so performing any kind of mechanical work (sawing, cutting, breaking, etc.) on millboard trill release fibers. RECOMMENDATIONS 1. Substitute materials should be sought and used wherever possible. 2. Where asbestos fabrics are used, they should be purchased as wet-brushed or resin-treated and whichever ASTM grade suits the applications. 3. Treated fabrics should either be purchased in needed sizes, or be cut to size with scissors or a sharp knife (not ripped or otherwise "violently" separated). 4. Places where cloth is cut should be cleaned daily to control any possible build-up of asbestos debris. 5. Cloth should be discarded when it has been in service long enough for the cotton binder and wet-brushing treatment to be burned away. The cloth thus has little or no strength and "dusts" easily. The time required for the cloth to become unsuitable depends upon the type of service, particularly the temperature. 6. Asbestos millboard should be purchased in needed sizes and not be cut or sheared to size after purchase. 7. Periodic asbestos-in-air sampling should continue and include area sampling as well as day-long, personal sampling.

It provides a cross-check from old style numbers to the new ones. Other styles, not listed below, will be continued, but the ones listed below are standard. Thermo-Pac 500-Styles 195, 4195, 4196 Thermo-Pac 750-Styles 4182, 4187 Thermo-Chem Glass Fiber--Style 770 Thermo-Pac 1000-Styles 4200, 4202 Thermo-Pac 2300-Style 4300 Thermo-Pac 2700-Style 4303 . INVENTORY RECOMMENDATIONS For simplified, economical inventory, J-M recommends stocking Thermo-Pac 1000 for all operations up to 1000F. This reduces the number of styles carried in inventory. It insures that the one rope carried will handle all services to 1000F. For operating temperatures above this, Thermo-Pac 2300 should be stocked; temperatures above 2300F are unusual and can be met accordingly. Check your requirements--sizes and temperatures. You will find you can reduce your inventory by standardizing on the J-M Thermo-Pac and Thermo-Chem styles and sizes for your equipment. tiiLiibitfiil CHEMICAL INDUSTRIES J-M Thermo-Pac 1000 is successfully used as calking rope for bell and spigot joints in chemical lines. Because it contains no organic components, it is used as yarning rope for water lines. In addition to its heat-resistance, the chemically inert characteristics have made it a "standard" in other chemical-handling operations such as packing for carboy-stoppers, and in Cryogenic services, and other applications where this property is required. Johns-Manville Thermo-Chemglass fiber rope Style 770 is recom mended for the most severe acid service (one example is for underground chemical sewers). ALUMINUM PLANTS Anywhere the control of heat and sealing is needed--heat-treating ovens, grooves for door sealing, pouring ladles, vacuum seals on crucibles, and in many other dry heat-sealing applications, J-M Thermo-Pac is the recommended sealing material. DOMESTIC APPLIANCES Throughout the Appliance Industry--on heaters, furnaces, incinerators and hot water heaters-in grooves between boiler sections, as door or lid seals, in furnace casings, on oil burner nozzles, and in gasketing of hot air furnace pipes--J-M Thermo-Pac is a standard. SPECIAL APPLICATIONS Manufacturers and users are constantly finding new applications for J-M Thermo-Pac. Examples: door seals on high-temperature dust collectors, seal between a 1000 watt electric bulb and the outer casing of outdoor floodlights, cushioning for acid carboys in crates, seals between cars in brick kilns, cushioning for Pyrex glass in a metal frame to compensate for unequal heat expansion, wipers to remove excess zinc in galvanizing sheet metal and wire, insulating "bubble-trays" in fractionating towers of petroleum refineries-and countless other uses! Thermo-Chem glass fiber rone. Style 770. is an excellent substitute for Thermo-Pac 500 and 750 where asliestoa is_not desired. 'ilft S3 3U E130I3M Ui'VSCOS K1 II STEEL MILLS AND FOUNDRIES Uses for J-M Thermo-Pac are almost endless. Sealing molds, sealing vacuum-pouring equipment (where leakage can ruin an entire billet), sealing sand molds off from pouring ladles, calking joints in large cores which must be segmented--almost anywhere you look, you will see high temperature rope in use. ATOMIC ENERGY J-M Thermo-Pac 1000 is standard in the Industry because it withstands an integrated neutron flux of 101!) NTV units. MARINE SERVICE J -M Thermo-Pac i3 an essential in the Engine Room for general boiler service such as calking, filling and expansion joints, wrapping hard-'o-reach steam lines. In emergencies, it is ideal for quick repair of damaged steam lines. On diesel-powered vessels, J-M Thermo-Pac is widely used for wrapping exhaust pipes, often "smoothed-off" with a coating of J-M Asbestos Cement. GENERAL INDUSTRY Anywhere heat sealing is required, whether heat treating furnaces, boilers or processing operations, J-M Thermo-Pac is recommended and widely used. POWER PLANTS Between boiler walls and brick-work to allow for expansion and contraction, wrapping steam and exhaust lines where space limitations preclude formed insulation, covering small ducts, calking hard-to-reach spaces, insulating hot pipes passing through fire-walls and bulkheads --there are literally hundreds of applications for various J-M Thermo-Pac Ropes. It is the standard for use in grooves for door sealing, between boiler sections, expansion joints and in handling hot gases. ILo-Ea G33 cat tdM la m oaia ca-sm C r-.... - ------------------------ ---------- -------- / JOHNS-MANVILLE THERMO-PAC AND THERMO-CHEM ROPES ARE BASIC TO INDUSTRIAL PLANT AND MARINE MAINTENANCE They are the ideal general-purpose ^ekings, whether for emergency packing and gasketing where other materials are not available, or where the shape or condition of the equipment will not allow the use of less pliable, less adaptable materials. These ropes are extremely versatile in that size can be reduced or increased--simply by separating the strands or building up thickness by twisting several together. They are available in a number of materials to suit your particular requirements --ranging from minus 400P to plus 2700F. In addition, for severe acid service, Thermo-Chem glass fiber, Style 770 which resists corrosive action by acids, is available for services to 750F. t l k On the foUoioing pages, y<m will find a description of many uses for J-M Asbestos,Glass Fiber and Refractory Ropes. i II,. |1 m j^mfL ijypp r Z3 THE MOST VERSATILE PACKING YOU CAH BUY e jgs4 it will enable you to specify Here is a new simplified way for you ^ the right product more quiek- to select and specify Johns-Manville H| ly and easily.

NEWARK, N.J.-An out-o(-court settle ment announced by a federal judge here could become a pattern for thousands of similar cases involving claims against as bestos companies and their insurers. Clarkson S. Fisher, a federal judge in New Jersey, said Friday a settlement was reached in the six-year-old case, which had coosefldated nine suits containing $80 sepa rate claims of S2 million each. Judge Fisher didst disclose any amount in his official fourpage settlement document However, the jbioclated Press said court records show (hat a $9.4 million fund has been set up to compensate 680 workers who had filed cults charging they were poisoned by asbes tos while working at a Raybestos-Manhattan be. plant in Passaic, NJ. A court clerk didn't dispute the figure. Defendants in the case, all makers of as crecy. Johna-MaaviUe and Metropolitan Lite declined to comment. The other defendaato couldn't be reached. Cautious About Claims Meanwhile, Raybestos's accountants : being cautious about future claims against their client. They are concerned about which theory will prevail In aasesalng damages: ''exposure" or "manifestation." Advocates of "exposure" believe that liability and i penses should be abend by insurers ot a pro rata basis over the period of the pleat- tiffs exposure to asbestos. Advocates of "manifestation" assert gag the insurance carriers on the date of plaintiffs' manifestation of an asbestoti^ lated disease should be respodslbie. Two court declstona-lwihidlnt one lgyit federal appeals court-hive used the expe- sure theory. -' If the exposure concept it' applied brdw bestos products, were Johns-Manville Corp., case of Raybestos, the company may be Blr Asbestos Corp. of America and three Cana bie for claims it hadn't provided for.
