l~ATIOt1AL BlISS~J~~S STAi;Dp .I. ms FOR ASBESTOS
On ~:ay 3, 1974 the Federal Register published clarifying revisions to the EPA Nat LonaL Emissions Standards for asbestos. They exempted l~fabricating" which wou l.d cover the rebuilding or the re-manufacturing of br~e shoe assemblies. The definition of manufacturing was clarified to indicate those sources that process commercial asbestos into a product. It does not consider a manufacturer to be one who cuts, shapes, assembles or otherwise alters a manufactured product that contains asbestos. This would leave the rebuilding operation outside of the scope of the national emissions standards for asbestos.
In these clarifying revisions they also give the definition of a visible emission. In essence it was stated that the "no visible eTI'issions"requirement does not apply to uncombined water if that is the sole reason for failure. An additional section on these qualifying revisions was that dealing with disposal of asbestos waste products. The agency will determine whether it is necessary to regulate these sources. No specific statement was made concerning waste disposal practices but the agency did indicate that they were going to look into this problem.
- --~,-
Hr. i,!eaveradvised that the EPA is considering steps to improve on the emissions sLandards and in particular is considering a numerical standard rather than the "no visible emissions" standard. There is no specific report of prooreas in this area as regards the EPA Emissions Standards.
c STATUS 0F TdE OSHA REGULATIOllS
During the year a suit was brought by the AFL-CIO against the Department of
Labor concerning the Occupational Safety & Health Act. Their petition was
aimed at strengthing (not we akenLng) OSHA regulations. The U.S. Court of
Appeals rejected their petition for review. In essence the OS:lARegulations
stand as they uere originally presented.
r
There is consideration of changing the OSHA Regulations to be more work-
practice oriented rather than based on numerical standards. rtr. Weaver
advised that the Labor Department no longer plans to completely rewrite the
standard. Apparently they will try to work in sections on work practices such
as housekeeping, warehousing and other areas. There is very little likelihood
of any easing in the two fibers Icc standard that is to go into effect in 1976.
There may be additional recommendations concerning practices to be used when introducing the asbestos fibers into the manufacturing process. In addition they are talking of monitoring techniques. medical surveillance and waste disposal.
~In response to a ques tdon it was stated that a respirator may be used for interim use when one is working towards getting the work place down to the five fibers/cc limit. H~7ever, the respirator is not a permanent solution.
MONITORING METHODS FOR SN'WLING ASBESTOS
A question came up concerning the EPA's measurement of asbestos concentrations in place of the "no visible emissions" standard. Mr. Heaver indicated that the EPA would like to get some kind of a measurement that they could rely on.

'. It was stated that the membrane filter me tr.od1:Tiththe optical mf crocope still
\. leaves a lot to be desired.
Work is being done on electron microscopy. Problems exist on how to satisfactorily pick up the sample that is to be ~easured. Dr. Jacko indicated that he had been working with the Nuclepore filter for their study for the EPA concerning asbestos emissions from motor vehicle brake and clutches. (The rlillipore filter is used in the OSHp- Regulations.)
A paper was shown that had been presented by the Franklin Institute Research Laboratories for EPt.. This report was entitled, "Development of an Instrumental Honitoring ilethod for Neasurement of Asbestos Concentrations in or near Sources". 1':1isused scannin'.electron microscopy with microprobe capability. The sc~~ning electron microscope can see the fiber but cannot tell the structure. The microprobe can identify the cherr~cal structure. It might be said that the electron microscope can count wh LLe the microprobe can identify. Further work is necessary to automate this counting.
It ~as stated that the current membrane filter method can be 507. off even with relatively skilled observers. In addition the results vary depending upon wh Ich section of the sample is counted. Hention was made of the Hillipore 1t~1C system for monitoring asbestos. TIlis is essentially an image analyzing method. The same microscope image seen by the operator is utilized but a digital computer performs counting and measuring flli~ctions.
( ~lr.Heaver mentioned that there Has instrumentation at a cost of less than
$10 ,000 which wou ld help in the counting. In particular he mendoued ~hp Coelter attachment on the binocular microscope which projects an irnase on a TV screen. One c~ measure length or diameter of the fiber digitally. It is considerably simpler than the measurement of asbestos under a microscope and there is less fatibue involved.
It was mentioned that in the Biospherics project foro 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 Hork and that he concluded that their results were reasonable.
EXPAJl)ING OF CO~IInTTE[ nrvoim AS~~STOS
The pros and cons of expanding this Co~~ttee's activities beyond the asbestos field were discussed. Hhile it was stated that many of the asbestos programs get into other problems such as Hork practices and plant disposal problems, it was felt that expanding the COlnrnittee'sactivities into the areas of heat stress, noise and safety related problems ~ght be biting off too much. It was stated that there are sufficient problems in asbestos related fields to keep this Committe,: busy without adding responsibilities. It uas suggested that if need were to be shovrn for a coomittee to delve into work practices it would be best if e Hork Practices Committee were established. The Asbestos Study Committee in the meanwhile will be involved ~yith work practices where they affect control of asbestos in the work place or the environment.
Upon motion duly made, seconded and unanimously passed, it was
RESOLVED: 7hat the Asbestos Study Committee Hill not expand their activities beyond the field of asbestos. Any such expansion should t ake the form of a new

There we re three papers to be given at this mee t Lng whd ch should have been of interest to the friction materials business,. 'Joe concerned e~osure of turnpike toll booth operators' to 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 emissions.
Another paper ~as that concerning observations of two brake lining manufacturing industries by CowIe, Rajhans, and 11oore. This paper (for some unkno\nl reason) was scratched from the presentations.
ine only paper of direct interest to the friction materials industry was that entitled. "Asbestos Exposure During Brake Lining Haintenance and Repair" by Rohl, t~derson, 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 durin;s tLe blowing off of brakes are in excess of the five fibers per cc allowance. Tnere was not sufficient observation usinr time
( weighted averages to give conplete balance to this paper. The paper was presented in an objective ~ashion and the Question and aliswer session that f ol.Lowedwas also handled objectively. No earth-shaking conc LusLons ve re made from this paper. It was obvious. hmvever, that there is a need for better work practices at the re-line and installation level.
ASBiSTOS L-rOPJiATIO:J ASS()CIATlm~ (AIA/NA)
In January 1974 ~k.R. H. t1ereness of the Asbestos Information Association wrote concernins listing the Friction ~aterials Standards Institute as an "affiliated association". At that time I indicated to r--;.r. Hereness that the Ins titute wou Id 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 v1here 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. Affiliationy as such) might move us into the target area. Another objection had to do with the legal status of any so-called affiliatior.. !tr. 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 .~bestos Study Committee is taking no position as regards being considered an "affdLLat.edassocdatLon" wi th the Asbestos Information Association.

UAF STUDY - ASBESTOS HORKERS' PI:i~SIONPLANS
There uas a brief article in the April 1974 issue of ASBESTOS magazine concerning the UAH's intention to study the qccupational hazards to which asbestos workers are exposed with a possibility tm~ards reopening pension plans for these workers. There were no additional specifics concerning the subject in the article.
In discussion it 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 r.~nufacture. There are some UAW plants working on the Asse~bly of brake linings or clutch facings which could also be involved. This wou Ld be the second area where UA\-!members might be involved "here 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 is the only significant use of asbestos other than in friction materials. It Hould appear therefore that any try for a pension program of "25 years and out" will be aimed at the friction materials business.
r"," I PELLETIZING ASBESTOS WASTE PR~DUCTS
~tr. Dave Stone of Bendix shm~ed 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. ~ssentially 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 land-fill. The pelletizing removes or reduces the problems with dust when a 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 land-fill site . Bendix will use this pelletizing operation at both their T::-oy,Ne'"York, and at their Cleveland, Tennessee
plant. The pellets are essentially wet balls when they are dumped at the land-fill. l~. 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.
FO~~ SPRAY FOR CO~ITR0L OF DUST
rtr. Stone showed an article on the use of a foam spray for controlling dust
in coal mines. (A;.JALYSISOF FOAlmROL FOA~1 AND ITS CO!1PARATIVE 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 durine the drilling or the grinding operations. It was
stated that one of the problems with a spray, or with a paint for that m2tter,
on the finished product was that it did have an effect on initial brake or
clutch application.

EFFLUENT GUIDELIHES FOR FRICTION pA..ATERI."M.AL:SWFACTURERS
Mr. Ueaver shm~ed a document prepared by Sverdrup & Parcel who are consultants for the EPA. This document was entitled, "Development Document; for the Proposed Effluent Limitatio~s Guidelines and New Source Performance Standards for the Textile, Friction lIaterials 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. lie suggested that I write individuals in the EPA. He gave the addresses for contacting Dr. r-ichard GreEl?;and Hr. J. E. Piley. The Secretary was directed to ge t copies of this document; to all ?lembers of the Institute.
There was a concurrent study being sponsored by the EPA which was being done by Arthur D. Little. This concerned the economic effects of EPA Effluent
Regulations. The Secretary was directed to contact r1r. Basil Igwe to see
what the status is on this work.

USE OF BRUSRE~ TO S~\L'}~CaINING OPE~TIONS
}lr. T:agner of Carlisle shoved a simple brush that he used in his machining 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. rtr. Hagner
indicated that steps such as this have gone a long way in reducing asbestos concentrations in the work place.
UJSTITITTE SDlINAR ON SAFETY AlID HEALTH
At the June 1973 meeting it was suggested that the Institute consider sponsoring a seminar on safety and health. ~ost of the subjects ~lere related to the as~estos 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 aujourn.
Adjourned: at 1:30 P.M.
