EPA concerning asbestos emissions from motor vehicle brake and clutches Millipore filter is used in the OSHA Regulations The A paper was shown that had been presented by the Franklin Institute Research Laboratories for EPA This report was entitled Development of an Instrumental Monitoring Method for Measurement of Asbestos Concentrations in or near Sources This used scanning electron microscopy with microprobe capability The scanning electron microscope can see the fiber but cannot tell the structure The microprobe can identify the chemical structure It might be said that the electron microscope can count while the microprobe can identify Further work is necessary to automate this counting It was stated that the current membrane filter method can be 50 off even with relatively skilled observers In addition the results vary depending upon which section of the sample is counted Mention was made of the Millipore + C system for monitoring asbestos This is essentially an image analyzing method The same microscope image seen by the operator is utilized but a digital computer performs counting and measuring functions Mr. Weaver mentioned that there was instrumentation at a cost of less than 10,000 which would help in the counting In particular he mentioned the Coulter attachment on the binocular microscope which projects an image on a TV screen One can measure length or diameter of the fiber digitally It is considerably simpler than the measurement of asbestos under a microscope and there is less fatigue involved - It was mentioned that in the Biospherics project for EPA which checked on . pollution of water by motor vehicles optical microscopy was used Dr. Jacko indicated that he had been in touch with those at Biospherics who had done this work and that he concluded that their results were reasonable EXPANDING OF COMMITTEE BEYOND ASBESTOS The pros and cons of expanding this field were discussed While it was Committee's stated that activities beyond the asbestos many of the asbestos programs get into other problems such as work practices and plant disposal problems it was felt that expanding the Committee's activities into the areas of heat stress noise and safety related problems might be biting off too much It was stated that there are sufficient problems in asbestos related fields to keep this Committee busy without adding responsibilities It was suggested that if need were to be shown for a committee to delve into work practices it would be best if a Hork Practices Committee were established The Asbestos Study Committee in the meanwhile will be involved with work practices where they affect control of asbestos in the work place or the environment *oge Upon motion duly made seconded and unanimously passed it was ; RESOLVED That the Asbestos Study Committee will not expand their activities beyond the field of asbestos wep Minutes of the Asbestos Study Committee _ -4- June 14 1974 * AAMMEERIRCAIL CAMEARICLAL INDUSTRIAL HYGIENE MEETING MEETING MEETING MEETING There were three papers to be given at this meeting which should have been of interest to the friction materials business One concerned exposure of turnpike toll booth operators automotive dust by Diberardinis Burgess and Lynch This paper was more concerned with the exposure to carbon monoxide and other gases from the internal combustion engine This paper was not concerned with asbestos exissions Another paper industries by was scratched was that concerning observations Cowle Rajhans and Moore This from the presentations of two brake lining manufacturing paper for some unknown reason The only paper of direct interest to the friction materials industry was that entitled Asbestos Exposure During Brake Lining Maintenance and Repair by | Rohl Anderson Nicholson and Langer This paper concerned itself with exposure to asbestos during brake relines primarily in New York city shops Some of the housekeeping conditions in these shops were deplorable They are perhaps no worse than in other shops throughout the country It may be that the brake lining industry can help promote better working conditions for those exposed to asbestos in the field in the shops that rebuild brake ~ : shoes or install and service brakes on vehicles The use of air hoses for cleaning off brakes is common Good work practices could be advocated The dust concentrations during the blowing off of brakes are in excess of the five fibers per cc allowance There was not sufficient observation using tize weighted averages to give complete balance to this paper The paper was presented in an objective fashion and the question and answer session that followed was also handled objectively No shaking conclusions were made from this paper It was obvious however that there is a need for better work practices at the line and installation level ASBESTOS INFORMATION ASSOCIATION AIL In January 1974 Mr. R. H. Mereness of the Asbestos Information Association wrote concerning listing the Friction Materials Standards Institute as an affiliated association At that time I indicated to Mr. Mereness that the Institute would be happy to consider itself an affiliated association In subsequent correspondence with members of the Board of Directors it was indicated that this was premature One director indicated that we might be exposing ourselves in an area where we now have a low profile That is the friction material manufacturers are not primary offenders like those in the construction field and in textile operations Affiliation as such might move us into the target area Another objection had to do with the legal status of any called affiliation Mr. Stickles indicated that there might be some objection to our being considered an affiliated organization and we would need more information . . _ ; There were several Board members who indicated that we should do whatever we can to support the Asbestos Information Association In our discussion at the meeting the consensus was that we should reciprocate and support the Asbestos Information Association However considering the absentees at the meeting it was decided not to make any resolution on this subject It was suggested that this be discussed further at the Board meeting in June The Asbestos Study Committee is taking no position as regards being considered - a we ee ee res eee ene ee eee ee ewe Minutes of the . Asbestos Study Committee -5- June 14 1974 -UAN STUDY - ASBESTOS WORKERS PENSION PLANS There was a brief article in the April 1974 issue of ASBESTOS magazine concerning the UAM's intention to study the occupational hazards to which asbestos workers are exposed with a possibility towards reopening pension plans for these workers There were no additional specifics concerning the subject in the article In discussion appears that the study is being made at the Chrysler Corporation Asbestos workers in the UAW are primarily involved with brake lining and clutch facing manufacture There are some UAW plants working on the Assembly of brake linings or clutch facings which could also be involved This would be the second area where UAW members might be involved where there are asbestos concentrations in the work place This would include such brake assemblers as the Bendix group in South Bend Kelsey Hayes Chevrolet Gear and Axle and Wagner Electric The most significant asbestos use in the automotive field is in brake lining Clutch facings are probably close second However there is asbestos used in air conditioning ducts for some Ford motor company vehicles This apparently and is the only significant use of asbestos other than in friction materials It would appear therefore that any try for a pension program of 25 years and will be aimed at the friction materials business PELLETIZING ASBESTOS WASTE PRODUCTS Mr. Dave Stone of Dendix showed some photographs of a sophisticated pelletizing arrangement for taking asbestos dust products from their dust collectors The process had been described at an earlier meeting Essentially a small amount of cement is added and the dust is formed into pellets and dropped from there into a truck for disposal at a fill The pelletizing removes or reduces the problems with dust whena truck is being loaded and when the dust is being disposed of For Bendix this operation did reduce the need for a watering operation at the fill site - Bendix will use this pelletizing operation at both their Troy New York and at their Cleveland Tennessee plant The pellets are essentially wet balls when they are dumped at the land Mr. Stone indicated that if other parties were interested in seeing this pelletizing operation he would make arrangement through members of the Asbestos Study Committee It is suggested that if individuals would like to see the installation at Troy New York that they contact a member of the Asbestos Study Committee FOAM SPRAY FOR CONTROL OF DUST Mr. Stone showed an article on the use of a foam spray for controlling dust in coal mines ANALYSIS OF FOANEROL FOAM AND ITS COMPARATIVE EFFICIENCY AS A DUST COLLECTOR It was his intention to follow this up to see if there were applications for the use of foam spray in the processing of friction materials Suggestions were made that if a foam spray got into the product during the mixing or briqueting stages that it could have an affect on friction material It was suggested that perhaps the best application for a product of this type was during the drilling or the grinding operations It was stated that one of the problems with a spray or with a paint for that matter on the finished product was that it did have an effect on initial brake or ed a eS s oO es tee ie ee ote ee ee eee ey oe s* mae te ee ee Minutes of the Asbestos Study Committee -6- June 14 1974 EFFLUENT GUIDELINES FOR FRICTION MATERIALS MANUFACTURERS Mr. Weaver showed a document prepared by Sverdrup & Parcel who are consultants for the EPA This documewnats entitled Development Document for the Proposed Effluent Limitations Guidelines and New Source Performance Standards for the Textile Friction Materials and Sealing Devices Industries This had been published by Sverdrup and Parcel for the EPA Immediately after the meeting I called Dr. Buzzell of Sverdrup and Parcel He did not have additional copies available He suggested that I write individuals in the EPA He gave the addresses for contacting Dr. Michard Gregg and Mr. J. E. Piley The Secretary was directed to get copies of this document to all Members of the Institute There a was concurrent study being sponsored by the EPA which was being done by Arthur D. Little This concerned the economic effects of PA Effluent Regulations The Secretary was directed to contact Mr. Basil Igue to see what the status is on this work USE OF BRUSHES TO SEAL MACHINING OPERATIONS Fa a Mr. Wagner of Carlisle showed a simple brush that he used in his machini operations The brush would permit the tools or the part depending upon the operation to move by into the enclosure where it was being machined drilled cut other Chips would fall down Dust would be collected The brush would seal the area where the machining was being done and reduce the dust that ordinarily would leak past the seal Also it permitted the dust collector to exhaust the asbestos dust with a greater vacuum They use such a device in grinding drilling and chamfering operations Mr. Wagner indicated that steps such as this have gone a long way in reducing asbestos concentrations in the work place 6 INSTITUTE SEMINAR ON SAFETY AND HEALTH At the June 1973 meeting it was suggested that the Institute consider sponsoring a seminar on safety and health Most of the subjects were related to the asbestos problem After questionaires were sent out and reviewed it was decided by the Chairman of the Asbestos Study Committee and the Secretary of the Institute that there was not sufficient interest in such a seminar for the Institute to sponsor it It was indicated that the members of the Committee or those suggesting such a seminar would have to take a very active interest in promoting such a seminar At this time the Asbestos Study Committee does not recommend further action as regards a seminar . There being no further business brought to the attention of the Committee upon motion duly made seconded and unanimously passed it was RESOLVED To adjourn 1 Adjourned at 1:30 P.M. E. W.
