INTERPRETATION OF THE OSHA REGULATIONS
The Asbestos Information Association AIA net with representatives from OSEA late in June The purpose was to interpret various individual requirements in the OSHA regulations Letters from the ALA to their member companies dated July 5 1972 and July 12 1972 were distributed to the Committee Members In the first letter they covered areas such as labeling clothes lockers

locked containing asbestos products but this letter also discussed | |
the problems of subsequent working of locked asbestos containing products
The members discussed some of the items in the OSHA regulations One member -,
indicated that during an inspection there were 3 OSHA people at their plant
for 7 to 8 days Interestingly the 3 OSEA people came on site the first day wearing respirators Whether this was for effect or is a standard procedure
for OSwH as A not known One of the items pointed out by an OSHA inspector
on thescenwe as the dry sweeping of loose asbestos compounds vs. the
wet sweeping or vacuum cleaning that OSHA calls for Another member advised
that they had taken out all air hoses around briquette presses and other
machinery where loose asbestos is handled before it becomes locked in
Surprisingly to some members asbestos sampling indicated that the inspection
One member required and drilling locations were problem areas
respirators be worn at all drilling locations
that the
In an inspection at one member's plant the OSHA people set up 5 stations and
while 4 of them sampled below the 5 fiber per cc TWA one station read 18 fibers
per cc THA
This member was cited in averaging the readings
When the Federal Goverment was considering the necessity for asbestos regulations two of the companies represented by Members on the Committee were asked to cooperate in a survey by NIOSE This study by NIOSH was to check over medical records and other such items to attempt to put the problem in prospective NIOSH had indicated to the cooperating manufacturers that the information they were providing would be kept confidential However as it turns out the OSHA people have copies of the NIOSH studies which would indicate that the confidentiality has been violated
A member questioned what happens when the asbestos concentration in a work area
exceeds 10 fibers per cc the ceiling concentration in the OSBA regulations
The answer is that the employer must notify the worker so exposed in writing
that he was exposed to such a concentration and the worker must wear a
respirator in that area The next question concerned what the proper means for
notification of the worker would be If an interpretation is officially asked
of OSHA they will indicate that a registered letter to the employee is the
proper beans of notification In other areas OSHA has indicated that meeting
the spirit of the law is what counts and it is felt that bulletin board
notification would suffice

LABELING PRACTICES
There are 3 areas for concern on labeling One is the handling of the loose
asbestos fiber from the point where it is received to the point where it is mixed and briquetted The next is the handling of the products with supposedly locked asbestos during subsequent operations such as drilling grinding inspection and boxing The last concerns the handling of the brake lining or
clutch facing by the customer where he may also do some drilling or grinding
before the lined assembly is finished product
It was reported during this topic that there was a higher concentration of
asbestos in the air in the Inspection Department than most members had realized
One member indicated that when pallets of brake linings were shipped there apparently is additional dust created during transportation The question of surface dust on the working surface of a brake lining or a clutch facing was
discussed Where members have taken action to reduce the dusty type surface
they have found that they have actually altered the frictional characteristics
of the material during the early miles on a vehicle In other words the
brakes are not very responsive during the early mileage after reline
In the AIL recommendations it is cuggested that where r^nufactureris shipping
his brake linings or clutch facings asbestos products he should
notify the user of his product to the effect Power bench saws without collectora
should not be used in curting this product If this is impractical operators. should be provided with a Bureau Mines approved respirator It was
suggested that a notification put in boxes of brake linings or clutch facings
being stripped to customers A sample of the caution labels suggested is
attached to these minutes Mr. Feierabend indicated that this recommendation
would not be accepted warmly by many manufacturers Mr. Wagner objected to the
recommendation that warning notices be put in the brake linings as he felt it
/
was another red flag that would bring more harm to the industry than the
|
alleged good that would come from enclosing such notices Several members have |
had customers call in to their Sales Departments asking if the handling of
asbestos in brake linings and clutch 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 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 asbestos would be a hazard Since small manufacturers are exempted
from the OSHA regulations they will probably not be rumming tests Larger
customers will of course be covered under the OSHA regulations and it is
expected that tests will be run in these manufacturers work areas Whether
the Institute would recommend such labeling in finished products shipped to the
customers was not decided It was felt that this subject should receive furthes
consideration from the Members of the Committee before a recommendation is made
One member commented that there were instructions by some manufacturers advising
that blowing out the wear debris from used brakes was not recommended
This subject of recommending that brake lining and clutch facing manufacturers
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 Members of the Committee with those responsible at their companies This item will cost definitely be on an agenda for the next meeting of the Asbestos Study
Committee

SAMPLING FOR ASBESTOS FIBER COUNTING
Mr. Stone questioned the possible movement of asbestos inside the filter sample
when sent to the lab for examination Mr. Weaver indicated that this
possibility was quite remote visit to the member's plant
Apparently the question arose after an OSHA In response to a question one member indicated
it takes about two months from the OSHA sampling until the OSHA report is
received Further it was indicated that the company hears if it is to be
cited and not if the conditions are satisfactory The OSHA regulations call
for an eight hour time weighted average TWA for the measurement of air-
borde
concentration of asbestos fibers One member indicated that he runs
his sample test for a continuous four hours to compute the concentration

Returning to the question on sampling for fiber counting OSHA recommends a full straight eight hour sample It was indicated they used 8 filters during this continuous sample A member suggested using 90 minute sampling for most
^rt^sof a completjoeb cycle if it tack longer than 90 frutes Re
recommended four hours of sampling for specials A member questioned as to what minimum time was necessary in sampling to determine the peak concentrations that cannot exceed 10 fibers per cc No specific answer was given but Mr. Weaver indicated some sampling procedures which he felt were optimum for counting fibers entrapped by the filter The number of tests for various conditions is suggested in this tabulation One condition is where you are measuring friction materials with asbestos in the compund and the other is for areas where you are handling all asbestos

The question arose concerning the sample where one is trying
for counting What about the other werials in brake lining
hazardous Might these not be counted on the filter as well as
to pick up asbestos
conside that are not
asbestos One
answer that is indicated for the skilled laboratory man making the examination
is that he should be able to distinguish between asbestos fibers and other
materials Further one can go to 800X 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 resins and other organic materials
primarily friction dust

EPA AUTOMOTIVE EMISSIONS
Dr. Spurgeon indicated that the Bendix Research Laboratories are working under contract for EPA on particulate emissions from brake linings and clutch facings and will not be finished until March 1973. Dr. Spurgeon felt it would not be proper to discuss results and progress to date on this study under
contract to the government
THE STATUS OF EPA REGULATIONS
-
Mr. Weaver indicated that one of the reasons for scheduling this meeting in August was to go over the new EPA regulations However this agency has not finalized their regulations as yet and it is not expected to be published until sometime in September Mr. Weaver indicated that the problem was not with the asbestos sections but rather with some of the other materials and he expected that their regulations will not be very much different from the earlier temporary regulations on asbestos Once again those earlier regulations were more concerned with control practices collectors and disposal techniques than
with numerical emission values No further action can be taken in this area
until the EPA regulations are published
CONSIDERATION OF SUBSTITUTES FOR ASBESTOS
At the Annual Meeting June this Committee was directed to consider a
recommendation that the Institute sponsor a research study to determine the
possibilities of substitutes for asbestos The purpose of this suggestion
was that if an outside study were to show that certain materials might very
well be acceptable substitutes for asbestos the information would be made
available to the members If the outside study indicated that there were no
satisfactory substitutes for asbestos in friction materials this information
\
could be used as a defense should we have a recurrence of action similar to
\
Illinois banning of asbestos based brake linings The Committee discussed this |
and as most of them are working on asbestos substitutes and some in particular
have marketed materials without asbestos primarily metallics 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 made seconded and unanimously passed it was
RESOLVED
That the Asbestos Study Committee 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 OSHA requirements will become EPA requireBeats In other words we 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 bags or other closed impermeable containers Whether a closed steel truck body is
considered Impermeable isa question If the OSHA people mean what they say

when they suggest that an employer who is attempting to meet the spirit of the law will not have difficulty it will be assumed that removal of the waste
material in enclosed steel truck bodies would be an acceptable means of
disposal Most members indicated that they had great difficulty with polyethelene bags - they are too soft and they tear when they are stacked The next area which is a major problem is the actual disposal of the dust Usually it is
unloaded as land fill One member uses a screw conveyor to fill a truck
_
with a fixed container The material is then dumped into land fill The
material is wet down after dumping and after a hole is filled it is covered up~
Mr. Stone mentioned a procedure he had seen where they turn the dust into
pellets and dispose of the pellets One member a indicated solution for the
disposal of the paper bags that are used to package the asbestos They unload
the asbestobasg inside a hood where they cut the bag
plastic bag which the asbestos bags are picked up in
The bood has an empty
.
The topic of proper disposal of the friction material waste products was discussed The most desirable method of disposing of friction material waste products is to put it back into the friction material Where a manufacturer has a formula product line this is reasonable However most of the larger manufacturers would find it very difficult to segregate the various mixes picked
up in their collection devices and recycltet back into the friction material
without running into product problems This is obviously the most desirabla thing to do with the waste material but for turning out a quality product it becomes very difficult The most common means of disposal are to wet the product down and dispose of it as land fill In some areas the material in
'
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 the question of the possibilities of the Institute sponsoring paid research on waste disposal It was indicated that within the Constitution and Laws of the Institute we could very well sponsor such research but it would be up to the Committee to make recommendations in this area Generally there are areas other than asbestos that are involved in this waste disposal problem Among the items to be considered are grinding dust asbestos fibers and bags phenolics which ar^ pcked up in wet scrubbers lead and its compounds and the solvents that are driven off during processing The Committee will consider this possibility at a subsequent meeting
A member suggested a possible questionnaire to be sent out to the Membership concerning the problems of waste disposal to see whether the rest of the Membership could contribute some information in this area and to determine the extent of interest in the study of waste disposal by the Institute The Members of the Committed should consider items to be included in such a questionnaire
for discussion at the next meeting of the Committee
MATERIALS OTHER THAN ASBESTOS
Because the problem of waste disposal is not a problem of asbestos only questions
were raised about the possibilities of extending the scopoef the Committee's
work beyond that of 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 hazardous materials being regulated by Federal agencies As many manufacturers use lead and lead compounds

METHODS FOR EXAMINATION OF FIBERS
Dr. Spurgeon questioned whether there were any other reliable tech for the
menturement of arbestos fibers other than the membrane filter method Tha
question question was also aimed at whether the regulatory agencies were consiering consiering
other analytical methods Mr. Weaver indicated that in conversation with AIA
he had recently learned that the Department of Labor is considering a study on
the possibilities of the gravimetric
methmeotdhod indicated that the nembrane filter method
for sampling asbestos firs Ec
build be in use for some s to
cons and possibl
up to the July 1976 date when the stiffer two Mber per ce
requirement goes into effect The Department of Labor is considering a 15 men
committee to study this possibility for sampling the asbestos The make of such a committee yould be as follows 4 from industry 4 experts 1 from MON
1 academic 2 from labor 1 medical 1 from the American Industrial Bealch
Association and 1 consumer advocate
It is suggested that members of the
voluntee Asbestos Study Committee consider whether their companies might wish to
for service on such a Federal committee
