Jt ny building is only as good. as its roof. And among the important parts of the roof are the sealants and caulks that help weatherproof it. Asbestos is widely used in these products because of the unique properties it offers and because It.adds to the strength and durability of the roof. But due to recent publicity concerning asbestos and the health issue, some manufacturers are seeking,replacements for asbestos. In spite of extensive re search and expense, no replacement has been found that offers the benefits of .. asbestos. As reported by one manufac turer to the Environmental Protection . Agency, these replacements can cost as much as 2000% more in.production than 'sealants containing asbestos. Substitute products result in poor oil absorption, poor sag resistance, a high settling rate and poor spreadabillty. . . And it's all unnecessary,. Asbestos in rooflng'sealants does not present a ' health hazard when properly handled. . ,. and applied. To ban its use could resuit in / the application of inferior roofing prod ucts and greatly inflated production' costs for manufacturers. There is no need to look for asbestos substitutes. Asbestos, like many other naturally oc curring substances, may pose a health hazard when handled Improperly. We now know that past high exposures in occupational and related environments, under conditions which existed years ago, have resulted in asbestos-related diseases among certain workers, par ticularly among those who smoked, These diseases continue to appear today because of the long lapse of time from initial exposure to the development of the disease.,. latency periods, in some instances, of more than thirty years. Today, we know that asbestos can be used without increased risk to health. This can be achieved by adherence to proper work practices and industrial hygiene and by compliance with regulatory standards. ' Today there need not be a problem. Since those days of early exposure, we have come far, both in terms of our knowledge of occupationally related, hazards in a wide variety of industries and in our ability to controf those expo sures. In.fact, asbestos workers are among the most highly protected in this country today. ' New understanding and well-established safety and work practices have made it possible to eliminate the conditions of thi rty an d forty years ago wh ic h contri buted to asbestps-reiated health prob lems. Johns-Manvilla does not manufac ture products which.cannot be used' safely, and the Company .requires that asbestos be encapsulated or "locked in" all products. So asbestos products do not pose a health problem if used properly. There's nothing like asbestos. Replacements? Maybe.

Containing Products and Health Medical and scientific research has revealed a potential health hazard connected with excessive ' exposure to asbestos in occupational environments. As a result, a considerable amount of research on .' asbestos has been directedtoward primary mining and manufacturing industries. Scientists have also looked at related occupations to determine if any risk existed. . ' '' ; . In the mid 1960's,, researchers found that some people engaged in the application of asbestos- containing insulations also exhibited an increased "" disease risk when exposures were excessive and continued over a long period of time. Efforts then were made to control the generation of asbestos dust in those industries. In some instances; where exposure control was difficult, personal protective equipment was supplied or substitute materials were developed; ;. . ...-Other occupational groups also have been identified i '" :being at increased risk.. These groups include ^shipyard workers who worked in- inadequately controlled work environments in the past, primarily in government-run naval shipyards. ' There also have been some isolated cases of disease in persons exposed para-bccupationally. These cases would include family members who were exposed years ago to excessive amounts of asbestos brought . home by family members who worked in , , ' ' ::the industry. ' ' ` ''' ' Although much research ^as`been completed, there is no evidence f&ny disease risk outside of occupational and para-occupational environments, and in those environments the disease has resulted from excessive, uncontrolled exposures occurring in the past, at which time the risk had not yet . . been determined. . Medical and epidemiological research has shown no evidence of any risk to. the general public resulting from the use of finished' products containing . asbestos, or from the release of minute amounts of asbestos fiber from such products into the ambient air. For even greater safety, Johns-ManviUe packings and gasket materials contain asbestos that has been encapsulated into the finished product with a strong bonding agent..-. Encapsulated products'will not, during normal handling and use, release asbestos fibers in excess of permissible limits.. In this way, packings and gaskets differ from the easily crumbled, friable , products used in the past. Because friable products do have the potential to create airborne fiber levels in excess of regulated limits during routine handling, the manufacture and sale of virtually all' of these products has been discontinued in the United States. In packings and gaskets, the asbestos fiber provides a reinforcing, function along with dimensional stabil ity and high temperature and pressure resistance: Because the fiber is encapsulated by the binder, normal handling, fabrication, and use need not result in the release of respirable fibers. For this reason, asbestos-containing packings and gaskets can continue to be used safely, providing a unique combination of cost and performance benefits. It is important to note also, that we now know . more1 about the potential health effects of asbestos and ways to use this material without risk than we know about many other potentially hazardous and toxic materials. Because a vast wealth of information on safe work practices is available to the person using asbestos-containing products, it is, in a veiy practical sense, potentially safer to use these products than many of the substitute materials about which little is known. \ i I i 2. NIBCO001345 Supporting Research Latest Studies In 1978, a report was issued on a study of "Asbestos Exposure From Gasket Operations", conducted by the Industrial Hygiene Branch, Occupational and Environmental Health Services,. Naval Regional Medical Center at Puget Sound'Navy Yard. The Navy found in this study that the gasket materials posed no exposure hazard, and reported: ` - "Analysis of data collected in all phases of the life cycle of asbestos gasket materials shows & number of interesting relationships. In general, average fiber concentrations obtained are well' below the current exposure standard of 2.0 fibers/cc, the proposed Department of Labor level of 0.5 fibers/cc, and 0.1 fibers/cc, which is the point at which reference (j) states medical monitoring will begin." The Navy further reported that even where house keeping was poor, the potential fiber release was . found'to be at or below the point where the Occupaf , "al Safety and Health Administration (OSHA) Yfciiftiires medical monitoring to begin. In mid-1980, industrial hygiene surveys were conducted at the facilities of a. large fabricator of gasket materials containing asbestos fiber. The surveys were carried out simultaneously by an. independent laboratory and; the Industrial Hygiene Section of Johns-Manville. The monitoring was performed according to government-recommended procedures and the analysis was conducted in; laboratories accredited by the American Industrial Hygiene Association. . ' In these surveys, eveiy manner of fabricating;' asbestos-containing gasket material's was scrutin ized.. The results of both thejindependent and1 J-M study'were similar:: all exposure concentrations measured were well1 below the OSHA. standard of 2.0 fibers/cc, in most cases from 10 to 20 times lower on the average. , (The results of these latest studies are included as Appendices A and B of this report.) Study Analysis In 1979, a comprehensive study was conducted by the Industrial Hygiene Section; Health, Safety and Environment Department, of the Johns-Manville Corporation, to determine the exposure levels related to use of mechanical packing materials containing asbestos. This series of tests reconfirmed the Navy findings and showed that asbestos fiber levels were consistently below the eight-hbur time-weightedaverage airborne concentration, at which OSHA requires medical monitoring tq begin. The studies included both personal tests on operations and sampling in work areas. In the Johns-Manville mechanical packing tests, both 'installation and removal readings-were taken, and normal and rough handling, situations were monitored. In no case did personal readings show levels of exposure above 0.1 fibers/cc. This reading is well below OSHA's recommended 8-hour time- weighted average airbone concentration of 2.0 fibers/cc. Area tests were similar, with only one workplace reading of 0.2 fibers/cc and the rest at or b^bw 0.1 fibers/cc. (A description of this study |||||t:luded as Appendix C of this report.) ` Based on the results of industrial hygiene studies, it is clear that the utilization of Johns-Manville mechanical packings and gasket materials need not pose any health risk, to fabricators or end-users. These mechanical packings and gasket materials can be used safely in the workplace with fiber, release being virtually non-existent. . . With levels of exposure below 0.1 fibers/cc, it can also be expected that in most workplaces, there would not be any requirement to institute medical surveillance of employees or to conduct repeated industrial hygiene monitoring under OSHA regulations for asbestos. 1 Most important, there would not be any need to replace the mechanical packings and gasket materials containing asbestos with substitute materials that would not be as cost-effective and might in some cases pose unknown risks to employees. 1 3 NIBCO001346 Suggested Procedures Conclusion Those people using asbestos-containing gasket materials and mechanical packings can assure the safety and health of their employees by following some simple procedures: .. . . Certain products,.such as oil seals, are so totally encapsulated that asbestos regulations would not apply from the outset, Those using other types of sealings and gaskets might find it advisable to contract For an industrial hygiene survey of their operations. If this survey shows levels to be. below 0.1 fibers/cc (levels found in the Navy, J-M and independent studies), then, according to OSHA Directive , #300-16, additional monitoring is not required .unless there is a significantchange in the operation. Medical surveillance also'would . not be required, . An industrial hygiene survey of any workplace is a good idea, since hygienists can check for other r~y*ntial hazards. A list of approved industrial {' l' -ene laboratories can be obtained from a local CisHA office or from the National Institute for Occupational Safety and Health (NIOSH) in Washington, DC. Those who have conducted industrial hygiene surveys of their operations should determine if the results are in line with OSHA requirements. If so, they should communicate this information to employees' to assure them that there'is no hazard resulting'from working with these asbestos products. Employers also may want to make,others aware of the results, including insurance carriers, to assure that rates are properly assessed. The challenge facing industry today is no longer the need to obtain safe asbestos-containing products. This challenge has already been met successfully through, manufacturing innovations and strict adherence to proper work practices. The challenge that must now be confronted is the lack of accurate information and the misconceptions that surround the use of finished products containing asbestos. As noted before,, the: results of numerous workplace studies indicate that the exposure levels that might result from the use of J-M mechanical pacldhgs and gasket materials are lower, usually 10 to 20:times lower; than the levels which the government considers to be safe for continuous exposure, 8 hours: a day, 5 days-a week.... . . Johns-Manville is totally convinced, therefore, of the viability of asbestos as a valuable and non-hazardous product component. It is,.howevef, essential to realize that the information contained in this report is of little value without good workplace conditions, good housekeeping, proper industrial hygiene, and an ongoing concern for worker safety and health. In fact, the safe use of asbestos-containing products is dependent upon appropriate work practices. When such practices are carried out, mechanical packings and gasket materials can continue to be safely handled and used in the workplace, offering the many advantages that make these products the most cost-effective materials presently available.

Manville Corporation ` Samples were taken to evaluate airborne asbestos fiber concentrations produced while installing several different styles of Johns-Manville mechanical packings for pumps. The field installation of each material was simulated in the Custom Engineered Products shop of Manville B Building, in Manville, New Jersey. Although no asbestos manufacturing operations were performed in this part of the build ing, some storage of asbestos materials did occur. Accordingly, two samples were taken on 4/17/79 to determine ambient levels. Readings/oFO.OO f/cc were found. Due to the low background readings, no corrections were applied to any of the subsequent test filters. , Six different types of pump packings were evaluated, "Tro side-by-side pumps were used, both ends of ^ Jiich could be packed. Therefore, 20 sections of packing were installed for each material tested. Specifically, the operation consisted of unrolling a section of packing, wrapping around a shaft, cutting to size, flattening with a hammer and pushing the section into the pump. End plates were tightened, the water system turned on, and both pumps run for a few minutes. Separate sampling was also performed during the removal of all test packings. Testing consisted of an area sample in the center of the two pumps and a simultaneous personal sample existed between careful (first reading) and rough handling (second reading). When no measurable differences were found, it was decided that all future packings would be handled as normally as possible. 13 NIBCO001356 v tininiaiy of Test Results For The Installation of Asbestos-Containing Packings Product Date Pump Packings CT 1 4-18-79 VG 1 4-19-79 .

All Johns-Manville packings and gasketing materials contain asbestos in an encapsulated form--the fibers are tightly bound in the product by elastomeric binders. When proper work practices are followed during fabrication, generation of airborne asbestos fiber is inconsequential and poses no threat to the health: of workers. Once fabricated, there is virtually no possibility of the asbestos fibers becoming airborne. In-fact, industrial hygiene surveys conducted by Johns-Manville as well as by an independent laboratory and by government agencies have consistently shown that workplace exposures from gasketing materials containing 5\, -v'l^iestos are 10 to 20 times below allowable iHA workplace concentrations. .. Therefore we firmly believe that the proper use of asbestos-based mechanical packings and gasketing materials represents no hazard to the health of users.
