Ppon notion duly nade, seconded and unaalaously passed. It vas RESOLVED: To accept the alnutaa of the February 10, 1972 nesting as distributed. INTERPRETATION OF THE OSHA REGULATIONS The Asbestos lnfomatlon Association (AIA) net with representations fron 0SBA late la Jose. The purpoae vas to latsrprat various individual requlrensnts in the 0SBA regulations. Letters free the AIA to their nsnber conpanles, dated July 5, 1972 and July 12, 1972, were distributed to the Onmlttee Menbers. In the first letter, they covered areas such as lawn^g, clothes lockers. FMSI-0127 P-FMSI- OC05 HItwi*** of Meeelag Aabeecos Study Conlttef ~2~ August 17, 1972 respirators, wmitoring and physical ersidnstiona, citations, OSHA inspsetions and oployss notification. la the second latter. the.AIA dlatlnjKuiahas be tween noD-locked-in asbestos containing prodKU^^WlcBiGoUffsftSrftzBli9!iiuqg. and clutch facings), there are certain labeling requirements tied la to the " non-locked-la containing asbestos -products, but this letter alao diecuesad . . the problsns of subsequent working of .locked-ln abbestos containing products, - ti Tba mashers dlaeuaaed mss of the Itans la the OSSA regulations. One aesber . indicated that daring an laapactloo, there were 3 OSHA people at their plant . * for 7 to 8 days. Interestingly, the 3 OSHA people cane an elte the first day wearing respirators, 'Uhsther this was for affect or ls,e standard pmcndnm for OSHA waa net known. One of the Itsne pointed out by.<an OSHA inepeetnr on the scene was the dry sweeping of looae asbestos-type conpounds we. the vet sweeping or weenun cleaning that OSHA calls for. Another neabar advised that they had takaa out all air hoeea around brlquatto presses and other machinery where loose asbestos is handled before it becones locked la. Surprisingly to sows neabers, asbestos sampling indicated that the inspection and drilling locations were problem areas. Onn nsaber required that the respirators be worn at all drilling locations. ** In an inspection at one M^er'a plant, the OSHA people set up 3 stations and vhlla 4 of than sapid below the 5 flher.-per cc THA, .one station reed It fibers per cc TWA. This nsaber was cited (In averaging the readings). When the Federal Covernnent was considering the necessity for asbestos regain* tlons, two of the esapeniee represented by hashers on ths Conaittea were asked to cooperate la e survey by HIOSB. This study by HIOSH was to check over asdics! records sad other such itens to attaapt to put the problaa in prospective. NI05H bed Indicated to the cooperating aanufactursre that the infornetloa they were providing would be kept confidential. However, as it turns out, ths OSHA peopls have copies of the NIOSH studies which would indicate that the confidentiality haa been violated. A eenber questioned what happens when the asbestos concentration la e work area exceeds 10 fibers per cc (the ceiling concentration in the OSHA regulations). Ths answer is that the snployer eust notify the worker so exposad, la writing, that he was sxpoasd to such a eoncsatratloa and the worker nuat wear a respirator in that area. The next question concerned whet the proper naans for notification of the worker would be. If an interpretation la officially asked of OSHA, they will ladlcata that a registered letter to the anployee is ths proper eeans of notification. Is othar erase, OSHA haa indicated that westing the spirit of the lar is whet counts and it is felt that bulletin board notification would suffice. disposable The next question concerned respirators. It was indicated that there were 3 / respiratorfPProv*dy the Bureau of Minna, end these aravaaaufactured by the A. O. Smith Co^umy, Walsh, and Minnesota Mining and Manufacturing (MMM). Respirators furnished employees oust have a proper fit and the enployees oust be instructed both as to tbs fit and the servicing of the respirator. Responsibility for testing sad approval of respirators for protection against asbestos dust re* ceatly was transferred fron Bureau of Mines to HIOSH. Until HIOSH approvals art issued, it is reeoansnded only respirators (reusable or disposable type) having Bureau of Mines approval specifically for use on asbestos dust be used in asbestoe contaminated atnospheres. ' Minutes of tteeelng Asbestos Study Coooletee -3- August 17, 1972 t AnFT.TMf; PRACTICES There arc 3 araaa for concern on labeling. On* -is the handling of the loose asbestos fiber Iron tbs point where it is received to the point where It is nixed end briquetted. .The next is the handling -ofthe"products with supposedly locked-ia asbestos during subsequent operations ,v such as - drilling, grinding, inspecdon and boxing. *rThs lest concerns the handling-, of the brake lining or clutch feeing by the customer where he may else dosome drilling or grinding before the lined eseeobly is arfiniehed product. . * le wee reported during this- topic that there was e higher concentration of asbestos la the air in die Inspection Department than aoet marfiexs bed realised. One aaaber indicated that when pallets of brake Uninge were shipped there apparently le additional duet created during transportation, The question of surface dust on the working surface of e brake or e clutch feeing wee discussed. Where members have taken action to reduce rthe dusty type surface, they have found that they have Actually altered the frictional characteristics of the notarial during the early;alias on e vehicle.<Jn other words, the brakes are not very responsive faring the early nileega after reline. In the AIA ter--ndatlons, it Is suggested that where e uanufactuxer is shipping his brake linings or dutch facings (lockad-in-asbastoe -products) he should notify the user of hie product to the effect, "Power bendi saws-without collectors should not bs used In cutting this product. If this is hqiraetleal, operators should be provided with e Bureanlof approved respirator.1* It wan suggested that e notification be .put in boxes of brake linings or clutch facings being shipped to custoeere. A saqpls of the caution labels suggested is attached to these adnutca. Mr. Fslsrabend Indicated that this reccssesni!stlon would not be accepted waxaly by any manufacturers. Hr. Wagner objected to the reeo--eendatlon that waning notices be put in the brake linings as he felt it was another "red flag" that would bring non harm to the Industry than the alleged good that would coaa from each notleec. Several neebers have had customers call in to their Seles Departments asking If tha handling of locked-ln-asbestos in brake i*igw and dutch facings is e hazardous condition. Another asked if this notlfcetlon was e requirement of the OSHA regulations. It was indicated that dlls was not pacifically required by the OSHA regulations. The concern is, do those customers doing additional grinding and drilling of the brake linings or clutch facings create working conditions where the con centration of aabestoe would be e hazard. Since smell manufacturers ere exempted from the OSHA regulations, they will probably not be running teats. Larger customers will, of course, be covered under the OSHA regulations and it is expected that teste will be run in these manufacturers* work areas. Whether the Institute would reco--send such in finished products shipped to the customers was not decided. It was felt that this si&ject should receive further consideration from the Maabers of tha Committee before e recow--endatlon is made. One meriiar rn--sauiad that there were Instructions by some manufacturers advising that blaring out the wear debris from used brakes was not recommended. This subject of recommending that brake lining and dutch feeing manufacturers include a warning sheet in their shipments appears to be sow--whet controversial and It is suggested that thla matter receive some serious discussion by the Members of the Covittaa with those responsible at their companies. This item will moat definitely be on an agenda for the next meeting of the Asbestos Study Committee. . IT Montes of Meeting iibutoa Study Committee August 17, 1972 SAMPLING FOR ASBESTOS TIBER CODHTIWC Mr. Scon* questioned the possible movement of ssbsstos Inside the filter sample when sent to the lab for exaodaatloa. Ur* Weaver .indicated that this possibility oos quite remote. Apparently the questionsoroee after an OSSA isle to the meri>erva plant. 4.2a response to e quest!an,-.one mmri>er indicated It takes about two months fromthe OSSA sampling raaeiltthe OSBA report is received. Further, It was indicated that the company hears'if it is to be cited end not if the conditions are satisfactory.'Xlhe OSBA regulations e*ii for an eight hour tisn weighted average (TUA) for the measurement of air. ` boras concentration of asbestos fibers. One nasber indicated thet be rune his ssnple test for e continuous four hours to cospnte the concentration. With e continuous four hour snapling, 'there are sometimes reactions froe the shop people. * Returning to the question on seapllng for fiber counting.' OSBA rsrn--uds e full straight eight hour aeaple. It was Indicated they -used 8 filters during this continuous saaple. A saber suggested using 90 sinute seapllng for aoet areas, or a complete job cycle if It took longer than 90 minutes. Be reroimended four hours of stapling for specials. A aanber questioned sa to whet miniflans tlae vu necessary in sampling to determine the peak concentrations that cannot exceed 10 fibers per cc. No specific answer was given, but Hr. Weaver Indicated soae sampling procedures which he felt were optima for counting fibers entrapped by the filter. The number of testa fot various conditions la suggested in this tabulation. One condition is where you are measuring friction materials with asbestos la the eompuad, and the other is for areas where you ere handling all asbestos.' Optimized time for fiber collection - depending on TKA fiber per cc concentration expected la area. (Optimum for counting fibers on the filter) Friction Materials TWA Fibers ear cc Optimum Number of Testa All Asbestos TKA Fibers per cc 0-5 5-10 10-15 15-20 - 1-8 hr. teat 2-4 hr. teats 3 tests, 3,3,2 hrs. 4-2 hr. tests 8-1 hr. tests 0- 3 3- 6 6- 9 9-13 13-20 The question areas concerning the sample, where one Is trying to pick up asbestos . for counting. Whet about the otnec*ifflKkri*ls in brake lining that are nof011*)***" hazardous? Might these not be counted on the filter as well as asbestos? One answer thet is indicated for the skilled laboratory man making the examination Is that hs should be able to distinguish between asbestos fibers end other materials. Further, one can go to 8001 on the microacope and get e closer look at the materials picked up on the filter. Dr. Spurgeon indicated that one can use low temperature ashing to remove rnsiae and other organic materials (primarily friction dust). --r mautma ot Meeting Aibutoi Stndy Coaoittee 5- August 17, 1972 PA AUTOMOTIVE PUSSIOHS Or. Spurgeon indicated that the Bendlr Research Laboratories ara working under contract for PA on particulate anlaalons froa braka lining* and dutch facing* and will not ba finishad until March J.973. -Dr. Spurgaoo fait it would not ba proper to dlacuaa * results -and -progress .to -data - on thin study under contract to tha government. . ... THE STATPS OT PA RECPIATIOHS He. Weaver indicated that one of tha raaaona for scheduling thla aaatlng In August was to go ovar tha nav PA regulations. Howavar, this agency has not final lead their regulations as yet and It is not expected to ba published until sonatina In Septanbar. Ur. Weaver indicated that the problea was not with the aabaatoa sections, but rather with scan of tha other materials and he expeetad that their regulations will not be wary nuch different from tha earlier taaporary regulations on aabaatoa. Once again, those earlier-regulations wars more concerned with control practices (collectors and .disposal techniques) 'than with numerical aaiaaion values. No further .action can be taken in this area until tha PA regulations ara published. CONSIDERATION OT SUBSTITUTES F0 ASBESTOS At tbs annual Keating, la June, this Coasdttaa was dlrectad to consider a reeoMsndatloa that tha Institute sponsor a research study to detaxadas tha possibilities of substitutes for aabaatoa. Tha porpoes of this mgaaiim was that if an outalda study wars to show that certain materials might vary wall ba acceptable substitutes foxv asbestos, tha information would ba made available to the aaabers. If tha outside study indicated that therm warm no satisfactory substitutes for aabaatoa la friction natarlala, this iafomatloo could ba used as a defease should wa have a recurrence of action similar to Illinois* banning of asbestos baaed braka linings. The Conaittaa discussed this and aa nost of than are`working on asbestos substitutes and one. In particular, have uarkatad aatariala without aabaatoa (primarily metal I Ice), they fait this suggestion would not ba wanly received by many mashers. One uauber Indicated that It would ba very difficult for than to sanction tha Institute asking any such study considering tha work they haws dona in tha past. Upon motion duly mad*, seconded, and unanimously passed, it was RESOLVED: That tha ftabearns Study Cemaitte* does not recoomead aa Institute study in tha area .of substitutes for asbestos. WASTE disposal Someplace between tha point wbera tha asbestos product is finished and tbs waste aatariala ara disposed of, tha OSHA requirements will become PA requirenests. In other words, wa ara moving from tbs condition of standards In the work place to standards in tha atmosphere or environment. Tha area of waste disposal is a major problea. All aabaatoa bearing wastes, according to the OSHA regulations, must b* collected and disposed of in sealed impermeable bags or other dosed impermeable containers. Whether a dosed steal truck body is considerad "laparacabla" is a question. If tha OSHA people aaau what they say ' Minutes of Hooting Asbestos Study Committee >6- August 17, 1972 when they ouggost thot on employer who Is attempting to asst the spirit of tbs lev will not have difficulty. It will bo sssusod that removal of the waste material in endoasd steel truck bodies would be .sn acceptable mmanm cf disposal. Most members lndlcstod that they had great-difficulty with polyethelene bags - they are too soft and they tear whan theycare (Stacked.-.The nest area, which Is a sejor problem,-ls-the-actual dlsposaltoftthe dust.^Usually,rit is unloaded os land fill, -a One masher uses a screw-type (conveyor-to fill a truck with a fixed container.The eaterlal Is then duepediinto land .fill. . The material la wet dewn after dumplng and, after a holstis lllled, it is covered up. * Hr. Stone mentioned s procedure ha had seen where' they 'turn the dust into ' pellets and dispose of the pallets. One msaber lndlcstod a solution for the disposal of the paper bags that are used to package the asbestoe. They unload the asbestos bag insIda a hood where they cut the bag..-The hood has an empty plastic bag which the asbestoe bags are picked up in. The topic of -proper disposal of the friction material .-waste products was discussed. Tbs most desirable method of disposing of 'friction aatarlal waste products is to put it bock into the friction material. * Where a manufacturer has a one-foraala product line, this is reasonable, a However. most of the .larger manufacturers would find it vary difficult to segregate the various wises picked up in their collection devices and recycle it back into die friction material without running into produet problems. This is obviously the most desirable thing to do with the waste material, but for turning out a quality product it becomes very difficult. The most cosmos msaxis of disposal are to wet the . product down and dispose of if as land fill. Xn some areas the material is bagged and sent to the dump. The problem of economical means to dispose of the waste from friction materials has been a problem in the industry for many years. It is likely to become a much more perplexing problem considering the regulations by OSHA and EPA. Dr. Spurgeon brought up die question of the possibilities of the Institute sponsoring paid research on waste disposal. It was indicated that within the Constitution and By-Laws of the Institute we could very well sponsor such research but it would be up to the Committee to make recoomendatlocs in this area. Generally, there are areas other than asbestoe that are Involved in this waste disposal problem. Among the items to be considered are: grinding dust, asbestos fibers and bags, phenolics which are peked up in wet scrubbers, lead and its compounds, and the solvents that are driven off during processing. The Committee will consider this possibility st e subsequent meeting. A member suggested e possible questionnaire to be sent out to the Membership concerning the problems of waste disposal to eee whether the rest of the Membership could contribute some Information In this arms and to determine the extant of Interest in the study of waste disposal by tha Institute. The Members of the Committee should consider items to be Included In such e questionnaire for discussion st the next meeting of the Coenlttee. MATERIALS OTHER THAU ASBESTOS Because the problem of waste disposal Is not s problem of asbestos only, questions were raised about the possibilities of extending the scope of the Ccmittee'e work beyond that cf ssbastos alona. Ths Secretary indicated chat It would be within the scope of the Coemittee to extend their activity to materials other than ssbastos. Load and lssd compounds are among ths hsssrdous materials being regulated by Federal agendas. As many manufacturers use load sad lead compounds Klcutes a Masting Asb--to# Study Ccs-tt-- 7 August 17, 1972 la thsir friction astsrlals, this night b a--tarlal to bs studlsd by tbs Ce--itt-- On tbs othsr hod. bsca--a of ths ssrlousasss of ths aobsstoo ragulstions, by taking on othsr --tsrlals, tbs sfforts of this Co--let-- night bo Ourrsatly, tbsrs srs xsgulatlo-- on solvents, silica, sad othsr astsrlals considered hassrdo--or noxious by ths regulatory sgtadss.
