The act became effective in April 1971 with the stated objective of assuring the workers' health and safety on the job. In December 1971 the Secretary of Labor issued a temporary emergency asbestos dust standard and the permanent standard was issued in June I9~2. The present OSHA asbestos standard of July 1976 has fur trust rgducid the allowable asbestos dust content in air and incriassd the scooe of labor and other expense involved in compliance with the law. The NatiO'i.-! Institute for Occupational Safety and Health (NIOSH) has been instrumental in having the asbestos standards strengthened through its recommendations to OSHA. In all cases, except for temporary emergency standards, public notice is given of proposed changes and re,rings are held before the N10SH recommendations become law. Asbestos, in_IRA Asbestos fiber and asbestos containing product* have ben available as coflimrcfal materials since the beginning of the manufacturing industry in this country. Meetinghouse up to the present has used piastic mol cad products, v,-ire insulation, tapes, cement-asbestos board, gaskets. O'-at a shoes, caperi, tubing, cloth and many other products containing asbestos reinforcement. The original selection of asbestos for use in electrical apparatus was made because it is fire resistant, a good dielectric, and creep resistant. For many years it was the only inorganic fiber rein forcement available in ccxwnerclal Quantities. Woven glass products were not introduced t i n after World War II and the large scale availability of glass mat and cloth molded compositions did not take place until the mid 1950's. Even with the introduction of 03114730 ro 76-31 Page 2 fiber glass, asbestos continued to be used because of unique reinforce ment properties. 4sbestos has the abilfty to break into very fine (finer than fiber glass) fibers when crushed or cut during manufacturing operations. this ability to keep splitting fibers rather than breaking them in short stubby pieces as >s the case with glass fiber Has now been widely shown to be the most critical factor in asbestos airborne pollution. Also the surface chemistry of asbestos makes it a hazardous substance when absorbed into the body. The hazard of breathing large quantities of asbestos dust Has been known sines ancienc Some and written references appear down through history. in the past forty years with the control of tuberculosis and a general increase in life span, asbestos dust has been mare widely > recognized as an industrial hazard. The- latent effects of asbestos exposure have become evident onlv in 'seen! years. LRA, Westinghduse has had a Safe Practice 0<sta Sheet A-20 covering asbestos limits and precautions since 1953 These precautions are similar to those found in present OSHA recommendations with the exception of airborne concentrations which have been reduced under recent federal 1 aws. Rcstri e t i o m ijnti I 1969 control of asbestos dust was rel-eted to various itats and industry standards some of which were established in the early I900`s. In ) % $ the Weish-Healy act which applied to public contracts was passed and a 12 fibers/cc standard placed in effect. The OSHA standard a few years later was set at 5 fibers/cc and was further reduced to 2 fibera/cc in July 1976. LRA was able to comply with the 5 f!brs/ec fn the past and it appears that the 2 fibers/cc limit will be met largely oy tne elimination of asbestos containing raw materials from LRA. L=% in P---T 03114731 -a 0 76-3) Page } T^erfi it a rea' possibility that all asbestos products -n)' dis appear from the market; even those products which IRA does not g d n d or machine. There is a proposal for a limit of 0,5 d h e r s / c c whicn if it oecOfTies !3 wou.fj for the rnost part eliminate the us-s of asbestos in any product. The Prgggn; Law and T>ads ecompendations Without going into details on each item the following list ij in cluded so the reader can understand the increased cost associated with using asbestos containing oroducts after July 1976. 1. A maximum allowable fiber concentration has been set as of July 1976 which is very difficult to meet (2 fibers/cc). 2. qu)om-en c should function below the limit of 2 n b e r s / c c and personal protective devices and clothing may be required. 3. Measurements and monitoring iaist meet recognized standards. i|. barning signs and labels are required. 5. Recorc keeping and medical examinations are required. In addition the Asbestos Information Association recommends the following for the workers1 persona! hygiqne. 1 . Do not smoke. 2. wash before eating. 3. Shower after work. U. Use protective devices and clothing properly. 5. Change t work d o m e s upon arrival at work and from them at the end of the shift using change rooms. 6. If work clothing is taken home carry ir* a bag impermeable to asbestos fibers and viash separately from other clothing. Neversruixe dusty clothing. Use a washing machine. 0 L 1 4 v7 a f t The ISA Progj-y; ;o ?'\=na Cut AsbestOS 10 76-.it Page A The Hampton Hicarta Qivision notified LRA in January 1976 that ;he manufacture of their assestos containing products would cease July i, 197.5 as a result of the new OSHA reguirements. Planning for the phase out of asbestos in LPA started in February, A program was approved {Appendix I) and monthly asbestos ccnmittee meetings have been held each month. This program has a scheduled total of 32-- 1/t* man months to the end of August 1976 involving all cocje Engineering, MSP and Development Engineering, Purchasing and Hanufacturing. In addition, Industrial Hygiene (60) and the Safety department (IRA) are included in the program, rt is planned that after August 1976, a somewhat smaller program will continue into the future because of long time tests of alternate materials and service reoufremenrs of machines sold In the past. Alternate Materials for CPA ' Sati s^actory msnreri a Ts are available for most items with the major exceptions being brake shoes and gaskets. These items reouire separate programs because: I. Suppliers have no alternates and no new suppliers have been developed through the Purchasing Department effort. 7. A 5ingle superseding item cannot be used in gasket applications without examination of each end use because of individual reaui rements. A list of active LRA asbestos containing items is found in Appendix ?r along with alternates and possible alternates. A few very low activity materials which are ordered by manufacturers' name (no westinghouse number1 can be expected to appear at times and they should be brought to the attention of the contsittee, Peconxneneiations I. A review of the asbestos program should be made at the end of v iv'i m '"* , I'nto" la"^i .inj revisions made where necessarv. <5*b Si ir"' --n to 76-31 Page $ 2. rt is recofnnended that smaller effort consisting of Purchasing, Materials development, Insulation Development and Hf?P Engineering continue the program into m'd 1977. 3. Hr. G. T. Srady, manager of Accident Prevention, E, Pittsburgh, should concinue his review of the program and have hi* representatives follow ISA manufacturing in regard to the small amount of asbestos items which will continue to appear in machines returned for service to East Pittsburgh or serviced in the field. U. The existing computer programs should be modified to print of drawings which show the use of asbestos containing materials and these drawings by coda group so they may be more easily followed. lists list 5. A separate development program for brake shoe and gasket materials should be undertaken. c.m? wv4-*| C. R.
