INTERPRETATION OF TBS OSKA REGULATIONS The Asbestos Information Association (AIA) met with representatives from OSHA late in June. The purpose was to interpret various individual requirements la the OSHA regulations. Letters from the AIA to their member companies, dated July 5, 1972 and July 12, 1972, ver# distributed to the Conlttee Members.

Oee menbar indicated that during an inspection, there vere 3 OSSA people at their plant for 7 to B days. Interestingly, the 3 OSSA people ease on site the first day vesting respirators. "Whether this vea for effect or is.e standard procedure for OSBA v*s not known.

Surprisingly to sene members, asbestos sampling indicated that the inspection ad drilling locations vere problem area.

This wesber vu cited (in averaging the readings). When the federal Government was considering the necessity for abates regula tions , two of the companies represented by Babers a the Ccoadtta vere asked to cooperate in a survey by MXOSB. This study by HIOSB vis to check over medical records and other such items to attempt to put the probins in prospective. KXGS1 had indicated to the cooperating namtfectarer* that the InfemtioQ they vere providing vould be kept confidential. However, oa it turns out, ebe OSHA people hove eople* of the NZOS studies which would indicate chat the confidentiality has bees violated. A member questioned what happens when the asbestos concentration in a work area exceeds 10 fibers per cc (the ceiling eanoantrstion in the OSHA regulations). The answer is that the employer oust notify the worker so exposed, in writing, that ha was exposed to such a concentration and the worker must wear a jraspirator Ja that area. She next question ceocamad what the proper means for notification of the worker would be. If am interpretation is officially asked of OSHA, they will indicate that a registered letter to the employee is the proper means of notification. Is other areas, OSHA baa indicated that teflng the spirit of the Xm ie what counts end it is felt that bulletin board notification vould suffice. disposable The cart qoratios concerned respirators* It was indicated that there vere 3 / respiretoripprovagy the Bureau of Hines, mod these are-manufactured by the A. 0. Smith Company, Welsh, and Minnesota Mining and Manufacturing (HMK). Respirator* furnished employees must have a proper fit and the employees must be instructed both es to the fit end the servicing of the respirator. Responsibility for tasting and approval of respirators for protection against asbestos dust re cently was transferred from Bureau of Mines to KIOSK. Gatil K3CSH approvals are issued, it is recommended only respiresora (reusable or disposable type) having bureau of Mines approval specifically for use on asbestos dust be used in asbestos contaminated atmospheres. Klautes of Meeting Study CoiggUW 3- August 17, 1972 LABBiMG mcnns There in 3 areas for ccneam on labeling.

One member indicated that when pallets of brake were shipped there apparently is additional dust created during transportation, the question of surface duet on the working surface of a brake HnS.g or a clutch feeing was 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 material during the early:miles on a vehicle# ether words, the brakes are not very responsive during the early mileage after refine# Is the A2A recoaammdatloos. It Is suggested chat where a manufacturer Is shipping his brake linings or dutch facings (locked-lo-asbestos -products) he should notify the user of his product tb the effect, "Power bench saws.without collectors should not be used is cutting this product. If this is impractical, operators should be provided with a Bureau:bf Hines approved respirator." It was suggested that a notification be:put in boxes of brake linings or clutch facings being shipped to customer*. A sample of the caution labels suggested Is attached to these minutes. >& Feietsbead indicated that tide VecomaMsdation would not be accepted warmly by many manufacturers# Hr. Vagner objected to the recommendation that warning notices be put is the brake linings as be felt it was another "red flag" that would bring more harm to the Industry than the alleged good that would cons from enclosing such notices. Several mashers have bad customers call in to their Sales Departments asking If the handling of locked-ia-asbestos la brake linings and dutch facings Is a hazardous condition. Another asked if this notifcation was a requirement of the OSHA regulations. It was indicated that this was not specifically required by the OSBA regulations. Tbe concern is, do those customers doing additional grinding and drilling of tbe brake linings or clutch facings create working conditions where the con- -ccocr'-aCioB of -ftob^fleos would be baserd. ^-TOrfM'.ni.wh^ -exempted from the OSHA regulations, they will probably not be running tests, larger customers will, of course, be covered under the OSBA regulations and it is expected that tests will be run In these manufacturers* work areas. Whether tbe Institute would recommend auch labeling is finished products shipped to the customers was not decided# Xt was felt that this subject should receive further consideration from the Heabsrs of the Committee before a reconendatlon is made# One member commented that there were instructions by seme manufacturers advising that bloving out the wear debris from used brakes was not recommended. This subject of recommeodieg that brake lining and cjnttih facing manufacturer# include a warning sheet In their shipments appears to be somewhat controversial and it is suggested that this matter receive some serious discussion by the lumbers of the Committee with those responsible at their companies. This item will most definitely be on an agenda for the next meeting of tbe Asbestos Study Committee. Minutes c Meeting Asbestos Study Committee * -4- August 1?. 2572 SAMPLING TO ASBESTOS FIBER (MTIBC Mr. Stone questioned the possible Boveaent of asbestos inside the filter sa^tle when sent to the lib for eacadBAtloa.

One aeaber indicated that he rune his sample test for a continuous four hours to compute the concentration. With e continuous four hour mapLing, there re soaetimea reactions froa the shop people. Returning to the question on sapling for fiber coasting,* OSHA recomends full straight eight hour sample. It wfts indicated they used 8 filters during this continuous sample. A aeaber suggested using 90 stance aaspling for Boat areas, or a conplete job cycle if it took longer than 90 rdautes. Be reconsended four hours of sapling for specials. A aeaber questioned as to what minimum tine vas necessary in sampling to determine the peak concentrations that cannot exceed 18 fibers per ec. Mo specific answer vas given, but Mr. Weaver indicated some sampling procedures which he felt were options for counting fibers entrapped by the filter. The number of tests for various conditions is suggested is this tabulation. One condition is where you are measuring friction nateriala with asbestos in the ceaptmd, and the ether la for areas where you ere handling &11 asbestos.

What about the otndc wferials in brake lining that ere oof******TM hazardous? Might these not be counted on the filter as well as asbestos? One ' anever that Is indicated for the skilled laboratory nan making the examination is that he should be able to distinguish between asbestos fibers and other naterials. Further, one can go to 800% on the microscope and get a closer look at the materials picked up on the filter. Dr. Spurgeon indicated that one can use low temperature ashing to remove resine and ether organic materials (primarily friction dust). Minute# of Meeting AbStudy Cosnittee August 17, 1972 gA AEIPHOTIVI EHISSIOSS Dr. Spurgeon Indicated that the Bendi* Research laboratories are working under contract for gA on particulate emissions free brake linings end dutch facings and will not be finished uafil Mar*-1973. -Ite. Sjsorj^oa felt It would not be proper to discuss *results .to-datepti, this study under contract to the government. THE STATUS OP gA PECULATIONS Hr. Weaver Indicated that one of the reasons for scheduling this meeting in August was to go over the new gA regulations. However, this agency has not finalised their regulations as yet end it is not expected to be published until sonatina in September. Hr. Weaver indicated that the problem was not with the asbestos sections, but rather with ease of the other asteriels and he rrpected that their regulations will not be very ouch different from the earlier, temporary regulations cm asbestos. Once again, those earlier regulations were more concerned with control practices (collectors end .disposal techniques) 'than with numerical ealesios values. No further.action am be taken in this area until the gA regulations are published. CCR3STD13ATX0JJ OP SUBSTITUTES TOR ASBESTOS AC the Annuel Heating, in June, this Committee was directed to consider a recommendation that the Institute sponsor e research study to deteraine the possibilities of substitutes for asbestos. The purpose of this suggestion was that if as outside study were to show that certain materials night very veil be acceptable substitutes for asbestos, the information would be made available to the meabere. If the outside study indicated that there were no satisfactory substitutes for asbestos in friction materials, this information could be used as a defease should we have a recurrence of action similar to Illinois* banning of asbestos based brake linings. The Connlttee discussed this and as most of then ere working on asbeetos substitutes and some, in particular, have narksted materials without asbestos (primarily metallise), they felt this suggestion would not be warmly received by many members. One member indicated that it would be very difficult for them to sanction the Institute making any such study considering the work they have done in the past. Upon .motion duly aiari*, -sAcaotded., .mad -unanimously passed, it -was RESOLVED: That the Asbestos Study Coo&lttee does not recommend an Institute study in the area of substitutes for asbestos. WASTE DISPOSAL Someplace between the point where the asbestos product is finished and the waste materials are disposed of, the OS&A requirements will become gA require ments. In other words, ve are moving from the condition of standards in the work place to standards in the atmosphere or environment. The area of waste disposal is a major problem. All asbestos bearing wastes, according to the OSHA regulations, must be collected and disposed of in sealed impermeable begs or other closed impermeable containers. Whether a closed steel truck body is considered "impermeable*1 is a question. If the OSSA people mean vhat they say Minutes of Meeting Stujjjr CoBdBiKUi August 17, 1972 when they suggest that as employer who is attempting to mot tbe spirit of the lsu will sot tare difficulty, it will he essiased that removal of the waste material la --*** steel truck bodies would be as acceptable weans of disposal.

Ur. Stone mentioned a procedure he had seen where* they'turn the dust into pallets end dispose of the pellets. One mesfear indicated s solution for the disposal of the paper begs that are used to package the asbestos. They unload the asbestos beg inside a hood where they cut the beg. -The hood has an empty plastic bag which the asbestos bags are picked up in. The topic of-proper disposal of the friction material:***ee products was discussed, the most desirable method of disposing of -friction material vaate products is to put It back into the friction material. Where a manufacturer has a one-formal* product line, this Is reasonable.However, moat of the .larger manufacturers would find it very difficult to segregate the various slixes picked up in their collection devices and recycle it back into Che friction material without running into product problems. This is obviously the most desirable thing to do with the waste material, hut for turning out e quality product It becomes very difficult. As most common means of disposal are to vet the product down and dispose of it es land fill. In some areas the material is bagged and seat to the dump. The problem of economical mesne to dispose of the waste from friction materials has been e problem in the industry for many years. It is likely to become e such more perplexing problem considering the regulations by OSSA and E?A. Dr. Spurgeon brought up the question of the possibilities of the Institute sponsoring paid research on waste disposal. It was indiestad that within the Constitution end By-Laws of the Institute we could very well sponsor such research but It would be up to the Cenm&ittee to make recommendation# in this area. Generally, there ere areas other than asbestos chat are involved in this waste disposal problem. Among the items to be considered ares grinding dust, asbestos fibers and bags, phenolics which are poked up in wet scrubbers, lead end Its compounds, and the solvents that are driven off during processing. The Committee will consider this possibility at a subsequent meeting. A-mwafewr suggested -a^posslhla questfonsalre "to he vest out *o tfoe"ttetavfcip concerning the problems of waste disposal to see whether the rest of the Membership could contribute eoae Information in this area end to determine the extent of Interest in the study of waste disposal by the Institute. Ihe Members of the Committee should consider items to be included in such e questionnaire for discussion st the next meeting of the Committee. MATERIALS OTHER TEAK ASBESTOS Because the problem of waste disposal is not e problem of asbestos only, questions were raised about the possibilities of extending the scope of the Cosmictee's work beyond that c asbestos alone. The Secretary indicated that It would be within the scope of the Committee to extend their activity to materials other than asbestos. Lead and lead compounds are among the hacarious materials being regulated by federal agencies. As many manufacturers use lead and lead compounds >Unute* of Meeting Asbestos Study Cawaletec ?- August 17, 1972 la their friction HttiiU, this might be a material to bo studied by the Cemedttee.
