H o e$ NATLSCO Naliond! toss CgnJrol Seryrcc Corporation GENERAL COTCTOSIONS The major product liability exposure associated with the use or misuse of the Model Numbers 880, 890 or 8000 brake shoe grinders and the Model No. 1250 brake assembly washer is-the potential of personnel operating these machines to inhale asbestos fibers present in the environment as a result of the brake grinding Dr brake washing operation. Ammeo has recently developed a new dust collection system for the brake grinders, which is designed to provide a more effective system of dust collection and to reduce the potential for operator exposure to asbestos fibers. However, the ultimate effectiveness of this dust collection system is, to a large degree, dependent upon the customer properly_installing, oper ating, and maintaining both the dust collection, system as well as the brake shoe grinder, The primary way in which an operator could be exposed to asbestos dust while using the brake assembly washer is by failing to purge the air from the system when the washer has not been used for an extended period of time. There is also some product liability exposure associated with the potential for the customer to misuse the product by using flammable solvents or gasoline in the unit to wash other automotive parts, rather than the detergent solution. These exposures can most effectively be addressed through instructional material provided on or with the product. It is extremely important that Ammeo provide adequate instruc tional material and sufficiently warn the customer of the proper installation, use and maintenance of their equipment, as well as the consequences of improper use, installation or maintenance. Much of this report is concerned with additional measuresAmmeo can take in both the warning information on the product itself and the maintenance and installation instructions which . are provided in pamphlet form with the product. Such infor mation serves two purposes -- it can reduce the number o-f incidents in the field by better informing personnel who use these products of the proper use and maintenance of the products, and can serve as evidence of Ammco's efforts to fulfill their "duty to warn" of the proper installation, use, and maintenance of the products, as well as the consequences of misuse of 'these products. This can greatly assist in ftmmco1s "defense should there be allegations of product defects related to a 'failure to warn. 2 H 0085 5 HATL CO NalloojI lass Control Service Corporation X. PRODUCT LINES Models 880. 890 and 8000 Brake State. Grinders - These machines basically function to automatically grind automotive brake shoes in order that the shoe Sits the curvature of the brake arum. Models 880, 890 and S0Q0 differ only in the type d> ' clamp which is utilized to hold the shoe in place during the grinding operation. The Model 890 is provided with a Model Number 8250 fixed anchor brake shoe clamp, the Model 880 is provided with a 'Model Number 8150 cam action brake shoe clamp, and the Model 8000 is provided with a Model Number S050 universal brake shoe clamp. These products are normally used by car dealers, independent garages, service stations, brake specialists, tire dealers, or other fa-oilities -who custom grind brake shoes- to match a specific set of brake drums. The machines all bear the Underwriters Laboratories listing mark. f The primary product liability exposure associated with the j brake shoe grinders is the fact that brake lining material I is normally fabricated from an asbestos compound, and during / the grinding operation there is a possibility of introducing j asbestos fibers into the air. The operator operating the L/J^uipment could conceivably breathe these fibers, Ammco has '" addressed this potential hazard through a dust collection system which, if properly installed and maintained, is designed to protect the operator from breathing asbestos fibers. .The system operates primarily by a blower which takes the material ground off the brake shoes and conveys this to a disposable plastic bag for removal. This system represents an improved version of a dust collection system. The new dust collection system was initially marketed for retrofitting on existing machines, but is now also standard equipment on all brake grinders. The old version of the dust collection system consisted of a fabric bag which had to be emptied by the machine operator when it was filled to a certain level and then reinstalled on the machine. The new system, which is now standard on all brake grinders, consists of a disposable plastic bag which fits into a metal canister. The disposable bag is fabricated from a heavy gauge, red plastic and is marked with the wording "CAUTION - Contains Asbestos Fibers - Avoid Creating Lust - Breathing Oust May Cause Serious Bodily Harm. " The metal canister has holes in the bottom, so that if the customer attempted to use the dust collection system without the plastic bag installed, the grinding dust would fall an the floor. 3 H 0087 NATLSCO Satin Loss Control Service Corporation t R B L E Qg- C O N T E N T S TITLE PAGE I N T R O D U C T I O N ............................ ........ . , . ................................... .......................................... 1 GENERAL C O N C L U S I O N S ........................... .. . . 2 I.

We wish to express our appreciation to M r . Robert Hampton for the courtesy and cooperation extended during our survey. All' recommendations developed in this report are based upon . information supplied by the client, sound engineering and management practices, and the professional judgment of NATLSCO`s consulting staff.

Product Lines - This section describes the four products which were studied and the potential product liability exposures of each. j H I - Corporate Functions - This section describes the exposures associated with the corporate operations 1I and recommends solutions in- greater detail. I V . Recommendations - This section summarizes all recommendations made in the body of -the report. 1 H 0085 5 NATL CO National Lois Conlrol Service Corporation Model 1250 Brake Assembly Washer - The Model 1250 assembly washer is intended to enable a mechanic to wash the entire brake shoe assembly without causing asbestos fibers to-enter the air. This system was developed as an alternative to the practice which has been in wide use by brake mechanics of blowing the asbestos dust from the brake shoes by means of compressed 'air prior to beginning work on the brake assemblies. This practice .tends to create a great deal of asbestos dust in the air. The Model 1250 brake assembly washer consists of a gun assembly and a wash pan assembly. Basically, the operation consists of spraying a detergent solution over the brake drum to wet down the brake parts and allow the dust and asbestos fibers to fall suspended in water into the wash pan assembly. Although the brake assembly washer is a product intended to reduce the potential hazards associated with cleaning the asbestos particles from the brake assembly, there is still some product liability exposure associated with the use of the system. Por example, when the washer has not been in use over an extended period of time, the detergent fluid will drain into the sump, and there will be some initial air coming out of the gun prior to the solution. This could result in asbestos dust being blown around the area: This situation is addressed in the brake assembly washer operating and assembly instructions included as Illustrations 1 and 1 of this report. In addition, there is some liability exposure associated with the potential misuse of the brake assembly -washer in that this product could be used with flammable solvents for parts washing and degreasing. This is an undesirable application, partic ularly since- there is no cover provided over the top of the wash pan assembly. ` Warning Labels Models 8BO, S9Q and 8000 Brake shoe Grinders - There are several warning" labels-provided on the brake shoe grinders. The label . included as Illustration 3 of this report is provided on the top of the abrasive belt guard. The label included as Illus tration 4 of this report is provided on the metal ring and guard assembly of the dust collection system. The label included as Illustration 5 of this report is riveted to the main base assembly of the brake shoe grinder. V 4 H OOSS NATLSCO National Loss Control Sefvic Corporslirt In addition, there are several precautionary and instructional tags -which are provided on each brake grinder. Illustrations S and 7 represent the caution tag -which, is provided to indicate operating voltage fox which the grinder is factory wired. Illustrations 8 and 9 represent-the motor manufacturer's recommendations for installation, running overload protection, lubrication, and sizing of branch circuit conductors. Model 1250 Brake Assembly Washer ~ At the present time, there are no precautionary or warning labels, provided on the brake -assembly-washer. We recommend that such a label be developed, and include several items: 1. The brake washer assembly utilizes a nonflammable detergent solution in water. Ammco sells packets of detergent to be added to one gallon quantities of water. Because of the utility and simplicity of the brake assembly washer, it may be attractive for service or maintenance personnel using the equipment for parts washing to substitute a petroleum base solvent for the detergent, Such solvents would act as a more effective degreasing agent and be used to clean other parts or for other applications in the service area. Although the present instructions for this unit include a cautionary statement indicating "DO NOT USE GASOLINE OR FLAMMABLE SOLVENTS," such a statement is not marked on -the product itself. It is recommended that a cautionary label be developed and applied to the unit. The content or wording of such a label should be similar to the wording which is 1 presently contained on the-back of the assembly- and operating instructions, included as Illustration 2 of this report. 2. It is not uncommon for the brake drums to be corroded to th e w h eel hub and stu d assem b ly, r e q u ir in g th a t th e drum be hit with the hammer in order to loosen it prior to removal. These striking blows to the drum can often create significant amounts of dust, i t is recommended that the warning label for the brake assembly washer include instructions for the ^user to wet down the entire brake drum assembly with the solution prior to removal of the brake drum itself. 5 H 0089 NATLSCO Manorial lo ss Control Service Corporalion 3. in addition, it is recommended that the warning label placed on the wash pan assembly caution the user regarding the necessity to start the pumping action by aiming the gun into the pan and depressing the trigger, prior to commencing washing of the brake assembly. For a warning label to be effective, it is important that the label remain legible throughout the life of the product on. which it is applied. The warning label on the abrasive belt guard (Illustration 3) is coated with a plastic film, while the label on the dust collector (Illustration 4} is fabri cated from uncoated paper. We .recommend that Airmco- carefully evaluate the.various types of labels, inks, and adhesives available, and select the type ox label^which exhibits the .. optimum durability over an extended period Of time. *". 6 H 0090 NATL5C0 National Lens Control Servici Corporation XI . EHGIJSERING In an effort, to evaluate the effectiveness -of the new dust collection system in controlling the emissions of asbestos fibers from the brake grinders, Ammco recently hired an independent consulting firm to measure the extent to which an operator is exposed to asbestos when operating the brake shoe grinding machine. Tests were performed on both a well maintained unit and a poorly maintained unit. The test report for these tests concluded that "asbestos concentrations as determined do seem to indicate that the present OSHA ceil ing limits would not be exceeded during brake dressing on a properly maintained brake shoe grinder.11 Ammco has recently instituted some changes to the new dust collection system on the brake shoe grinders. The plastic dust collection bag has been decreased in size. Originally, a standard size plastic bag was utilized, but this bag was too large, and the installation of the oversize bag could result in a bunching of the plastic bag around the outer rim of the metal collection drum. This could result in small gaps around the rubber gasket where the drum is fastened to the underside of the collection system's fabric bag, resulting in emissions of asbestos fibers during operation of the machine. Ammco has discontinued the use o f 'this larger bag and now supplies a smaller bag designed specifically for the dust collection system, eliminating the problem of the colblection bag bunching up. Ammco has also recently developed an arbor plug for use on its Models 380, 890 and 8000 brake shoe grinders, The purpose cf this plug is to prevent brake shoe dust build-up in the arbor and to improve the air flow through the abrasive belt guard to -the dust collection system. The installation in struction sheet for the arbor plug is included as Illustration 12 of this report. V 7 H 0091 ' NATLSCO Hatfundt Loss Con Jrof Service Corjwjraiion III, QUALITY CONTROL When each brake shoe grinder is completely assembled, each unit is calibrated by adjusting the settings for specific shoe sizes. In addition, each unit is tested, but this test consists basically of operating the unit to verify that the motor is electrically operable. A log is kept of the serial numbers for each unit versus the motor si2 e and type which is provided, as there are several different motors available for the brake shoe grinders. It is at this final inspection point that all appropriate warning labels are put on the units, and the units are tagged with the tags which normally are put on the unit. The service and-maintenance information is put along with the unit into the packing crate. Aside from the log of serial numbers which is kept, there is no record kept of the calibration or quality control in spection or tests which are p e r f o r m e d W e recommend that Ammco develop a quality control checklist to be used as a final check on the assembly of tha brake shoe grinders. This chec ator k list shou l dshoc uhle dc k list pri all the or to sh critical ippingthe items whi machine. c h the For oper example, the following items should be verified. 1. All warning labels firmly secured in plaoe. 2. Calibration of the unit. 3 Operation of the unit, 4. Inclusion of the service manual. It is recommended that a checklist form be developed for this purpose, and that the form include a space for the inspector to record the serial number of each machine checked, the manufacturing date, and the verification that all of the various inspections and tests have been performed. These completed forms should be kept as part of the permanent quality control records of the machine. w- 8 H 0092 'NiVRSCQ National Lois Control Service Corpora lion IV. ASSEMBLY M D OPSRATIM~G INSTRUCTIONS Brake Assembly Washer Model 1250 The brake assembly washer is presently being provided with the assembly and operating instructions included as Illustrations 1 and 2 of this report. As discussed earlier in this report, it is not uncommon fcr a brake mechanic to hammer on a~ corroded drum to attempt to loosen it prior to removal of the drum for servicing the brakes. These striking blows to the drum can create significant amounts of dust, and asbestos particles inside the brake assembly can be blown into the air. This fact was borne out by the analysis conducted by the independent test laboratory. He recommend that the brake assembly washer instructions be modified to include an initial step in the process Where the entire brake drum assembly is wetted down with solution prior to removal of the brake drum itself. This should be depicted in the instructions by means of a photograph, as well as written copy. In addition, a separate set of cautionary instructions should be included on this instruction sheet. These precautionary instructions should precede the operating instructions and should be printed in red or some other brightly contrasting color for emphasis. The following areas should be emphasized in the set of precautionary or safety instructions! 1. The fact that the entire brake drum should be wetted U down prior to removal of the drum. 2. The fact that the user should assure that the pumping action of the detergent solution has been started prior to aiming the gun, into the brake assembly. 3. The fact that the brake assembly washer should never be used with gasoline or other flammable solvents. Models 8B0, 890 and 8000 Brake Shoe Grinders At the present time, the Models S80, 890 and 8000 brake shoe grinders are provided with an "Operating Instructions and Parts Identification" manual. This manual is an 8% x. 11 brochure which is some 12 pages long and is intendea_to be kept in a loose leaf binder by the customer. H 0093 NATLSCO National Loss Control Service Corporation It is extremely important that this manual effectively communicate the proper operation and maintenance procedures far the brake shoe grinders, since, to a large degree,-the effectiveness of the dust collection system in controlling the asbestos dust exposure is dependent upon proper in stallation and maintenance of the system. In addition, it is important that ftmmco warn the user not only of the proper procedures and steps- to be taken in operating and maintaining the equipment, but also of the consequences of the user not following these instructions. We have reviewed the present. manual referenced above {flmmco Publication No. 8818-6-761 and have the following recommendations for additional infor mation and revisions to the manual: 1, It is recommended that the inside front cover of the manual have a set of safety instructions printed in red or some other brightly contrasting color and entitled "IMPORTANT." .These instructions should be a summary of the information presently dispersed throughout the manual related to the proper use and maintenance of the dust collection system, as well as other precautions which must be taken to assure . the environmental safety of'the individual operator. The areas addressed in these safety instructions should include, but not be limited to, the following; a) A statement indicating that breathing asbestos dust may cause serious bodily harm. b) > A statement indicating that the dust collection system must be properly cleaned and maintained for continued safe operation. a) A statement indicating that the grinder should never be operated without the disposal bag properly installed. d) A statement indicating that only Ammco replace ment bags should be used. e) A statement cautioning the user to only use Ammco abrasive belts. f) A statement cautioning the user not to remove more than .005" on any one cut. V 10 H 0094 NATlSCO National Loss Control Servies corporation 2. Page 3 of the manual should illustrate the new dust collection, system, which we understand is now standard on all models In addition, the appropriate instruc tions for this dust collection system'{see Illustra tions 10 and 11) should also be included on Page 3. 3, Page 4 of the manual contains instructions for replacing the abrasive belt, which actually does the grinding of the braJcB shoe material. Replacement of this belt requires removal of the cylindrical abrasive belt guard* In addition to protecting the user from accidental contact with the grinding surface of the machine, the guard housing serves as a means for collecting the asbestos dust from the grinding operation before it is sucked into the collection bag. Therefore, the. abrasive belt guard is somewhat critical to the safe operation of the machine, we recommend that the instructions for replacing the abrasive belt include a step advising the user to replace the abrasive guard after the belt has been installed. This should be shown both graphically and also indicated in the copy of the instructions. 4. Page 4 of. the manual also includes some lubrication instructions for the machine, as well as a paragraph statingi "In general, keep a clean work area. For your environmental safety, do not allow asbestos dust to accumulate anywhere but in the Amrnca dust bag or in closed containers." It is recommended that this para graph be highlighted by printing in a different color, printing in bold print, or some other graphic technique " in order to emphasize its importance. In addition, the . paragraph Should include a statement to the effect that any accumulation of dust could be ah indication that the dust collection system is either not functioning properly or the dust collection bag needs to be changed. 5, Page 4 of the Introduction Manual includes a set of statements under the general head ing "CAUTIONS ." These cautionary statements should also be highlighted by means of contrasting color, bold print, or other graphic techniques. In addition, it is recommended that the Statement "DO NOT REMOVE MORE THAN ,005 INCHES ON ANY ONE COT - MORE WILL ONLY SLOW THE MOTOR AND REDUCE DUST COLLECTION EFFICIENCY" be expanded to provide a more specific indication of the consequences of having reduced dust collection efficiency and the potential dangers associated with asbestos dust. v 11 H 0095 i NtfLSCO National los* Control Service Corporation 6.

The right-hand column on this page begins with the heading "GRINDING t h e SHOE: BEFORE STARTING THE MOTOR.,.," Xt is recommended that this.section of the instructions he expanded to include " some copy indicating that the operator should verify that the dust collection system, as well as the abrasive belt guard/ are properly installed on the machine prior to starting the motor. 7. Pages 6 through 11 of the manual are basically replace ment parts lists and illustrations. When the manual is revised, the parts list should include the new dust collection system parts, including the replacement bags. These bags are a heavy-gauge red plastic, designed and sized specially for the brake shoe washer, and include a cautionary statement. Because these bags are quite similar to commonly available plastic trash collection bags, it is foreseeable that the user of the machine would substitute such bags rather than order the proper bags through Ammco. It is recommended that the re placement parts portion of the manual include a statement to the effect that the bags have been specially designed for use with the asbestos dust collection system and other bags should not be sub- stituted, 8. At the present time, the motor manufacturer's installation, running overload protection, lubrication, and branch cir cuit conductor sizing instructions axe included on a tag - which is attached to the brake shoe grinders when they are "shipped to the customer, We believe that it is highly likely that this tag will be discarded once the machine is installed. Since the tag contains important information "related to the safe use and operation of the equipment, it is recommended that the motor manufacturer's information be duplicated and provided as part of Ammco's assembly and operating instructions manual. Turbor Plug Instruction Sheet (No, 11181) The arbor plug is intended to be installed in the arbor for the abrasive belt, and is intended to prevent brake shoe build up in the arbor in order to improve the air flow through the abrasive belt guard to the dust collection system.

SUMMARY OP RECOMMENDATTONS WARNING LABELS X, Xt is recommended that a precautionary or warning label be developed for the Model 1250 brake assembly washer. This label should address the potential exposures associated -with using a flammable solvent with the brake assembly washejr, not wetting down the brake assembly prior to removal of the drum and the potential fox air coming out of the gun assembly when the unit has not bean used over an extended period of time. 2. Ammco should review the physical characteristics of warning labels and determine the label material, ink, and adhesive which will afford the optimum durability over an extended period of time. q u a lity control 5. We recommend that Ammco develop a quality control check list to assist assembly personnel in the final inspection of the brake shoe grinders, as Well as to serve as a record of the fact that such inspections have been con ducted . ASSEMBLY AMD OPERATING INSTRUCTIONS Brake Assembly Washer 4. It is- recommended that the brake assembly washer in structions be modified to include an initial step in the process- where the entire brake drum assembly is wetted down prior to removal of the brake drum itself. 5. A set of precautionary instructions should be included and should be printed in red or other brightly contrast ing color for emphasis. These instructions should precede the operating instructions. 14 H 0098 NATLSCO NaJicmal Loss C onirol Service Corporation Brake Shoe Grinders >, 6 . It is recommended that the inside front cover of the instruction manual have a s a t of safety instructions printed in red or brightly contrasting color, and entitled `'IMPORTANT ,," 7. The manual should illustrate the new dust collection system which is now standard on all models, and should include appropriate instructions for this system. 8. The instructions for replacing the abrasive belt should include a step instructing the user to replace the abrasive guard after the belt has been installed. 9. It is recommended that an Page 4 of the manual, under the "Lubrication Instructions," the paragraph relating to asbestos dust include a -statement indicating that any accumulation of dust could be an indication that the dust collection system is either not functioning properly or the dust collection bag needs to be changed. 10. It is recommended that the statement "DO NO T REMOVE MORE THAN .005 INCHES ON ANY ONE CUT - MORE WILL ONLY SLOW THE MOTOR AND REDUCE DUST COLLECTION EFFICIENCY" be expanded to include specific indications of the consequences of having reduced dust collection efficiency and the potential dangers associated with asbestos dart. 11.

Okay, When you Joined AMMCOin 1975, Q. And I think you told me thesameAMMCO 16 were you aware at that time, yourself, that 17 18 facility kept going on with business; yon kept working, they retained the AMMCO name; is that 17 18 brake linings were made still, in part, out of asbestos? 19 20 right? A Yes. 19 A. Yes. 2 Q. Okay. And I thinkyou --well,we'H 21 22 Q. So there-s a lot of fine print on Exhibit 4, and I'm going to spare everybody 21 wait until we get to some of the other 22 documents, I guess. 23 24 from having to read it ail, but can you basically tell me--you called it an 23 Okay, It lookslike from the picture 24 that the brake grinder, the Model 2000, has a 15 (Pages 54 to 57) EPPLEY CO(5U08R)T47R8E-P97O9R5TING, LLC Craig Mounts June 26, 2007 58 60 1 label or tag on it that says "Safe-Arc Brake 2 Shoe Grinders." Was that a trade name? 1 Q, And Ithink you've testified 2 previously that AMMCO first put an asbestos 3 A. Yes. 4 Q, That -was a trade name of AMMCO? 3 warning on their brake grinders in '73 in 4 response to the recent enactment ofOSHA; is 5 A. Yes. 6 Q. And it has the AMMCOlogo on there it 5 that fair? 6 MR. DELUCA: I'just objectto the form 7 appears; is that right? 8 A, Theold one, correct 7 ofthe question.

North Chicago, Illinois Page Two sample was removed to expose the entire area' of the filter during sample collection. Air was drawn through the filter at 2.0 liters pe r minute, and the sampling media w a s positioned as close as possible to the breathing zone of the exposed employee, except for the general 'area samples which we re positioned at indicated locations, at approximate breathing zone height unless otherwise noted in the tables. .Subsequent to collection, the filters were, brought to the HATDSCQ Environmental Sciences laboratory where fibers were counted on the filters using phase contrast microscopy techniques at a magni fication of 450. The KATLSCQ Environmental' Sciences' laboratory is accredited by the American Industrial Hygiene Association -and licensed by the tr,S. Department of Health, Education, and W e l f a r e 's Center for Disease Control. The Time-Weighted Average Exposure was. calculated using the for mula t C t T i fr C 9 T ? + Ts CnTn Where C represents the contaminant concentration, T th sampling time at that concentration, and Ts represents the total sampling time. . The conditions under Which air sampling was conducted is defined as follows ; Work room: 60'1 H x 38'6" x 19 '4" (height) or 44,727 ft.3 All doors and bays closed ' Ventilation in the room consisted of recirculating warm air through 2 warm air returns mounted about 10 feet above the floor. 2- Grinders; Two Model 880 brake shoe grinders were used, both equipped with Model 8150 earn action brake shoe clamp, and the Model 8925 Dust Collection system. It is felt that air sampling results would ha ve be similar with the.other grinders (Model 890 and 8000) since they differ only in the type of brake shoe clamp employed. The sanding drums bn each grinder rotated at 3450 rpm. The-grinders were positioned a few feet apart on `the south side of the room .The "poorly maintained" brake shoe grinder was several years old, and had been used considerably. The inner plastic 'collection bag of the 8925 dust VV.iWi V U - J fNJAalTioLtiSdCl OUw- sCml>l ,Service CoiDOraliun mmco Tools, Inc. North Chicago, Illinois Page Three collection system was about h a l f full. The bag was oversized, and as .a .result was bunched in spots around the outer rim of the metal collection drum. As a result, small gaps were present around the-rubber gasket where the drum is fastened to the underside of the collection system fabric bag. It was observed that puffs of dust were blown out from around the gasket during start-up of the poorly maintained grinder. The "well maintained" grinder was about th .same age, but the dust collection system had been cleaned, and a fresh, unused plastic bag was apparently carefully fitted in the Dust collection ' System. No dust was observed to have been blown out through the gasket junction of the drum and fabric hag during operation. 3. Comparison Grinder tests: (See attached tables) General area air samples w e r e duplicated -on both . . grinders during same typical dressing of brake shoes; In addition, samples were duplicated during . the destroying of.brake linings. In all, about 16 total grindings we re made, on eight different shoes, at each of the two brake shoe grinders. In the opinion of the operator, this represented a good day's w o r k in a typical garage.-. 4. Other grinder tests: In addition to the above tests, follow up air samples were, taken on the "poorly maintained" grinder after the dust collection bag was replaced and the metal collection drum was washed. A test was attempted with the collection system disconnected, but this was terminated w h e n it became apparent that large amounts of dust and fibers would accumu late in the air when shoe grinding was done. 5. Grinder operator personal exposure; During operation of both grinders, personal samples to evaluate operator exposure to asbestos fibers were taken. The time weighted average exposure for the sampling' period was calculated for the operator based on the results of each-set of samples taken at the "poorly maintained* and "well maintained" grinders. x V ' NATLSCO 'f illio n j!

Brake shoe washer:' Air samples to determine area concentrations of, and personal exposure to, asbestos fibers was done during the use of the m o d e l 1250 Brake Assembly Washer -with the #1256 Brake Washer. Con centrate. . lhe car (a late 6 0 1s model Chevrolet) was located on the lift in the same workroom, about 20 feet diagonally northwest of the brake shoe grinders. This test was considered a good example of a set of wheels in poor shape, with heavy corrosion and a large deposit of ground material contained in each wheel. DISCUSSIOH The samples taken during destruction of brake shoe linings showed that during such abuse, Significant fiber concentrations were generated in the operator's breathing zone, as well as in the general area. Based on visual observations made during the aborted te.st during grinding, w i th the Dust Collection System detached, it is advised that these brake shoe grinders always be employed with the. use of such a System. Excessive airborne asbestos fiber levels could be generated in the absence of the Dust Collection System. Based o n visual observation made during brake washing, it is advised that the outside of the wheel be wetted if possible before -hitting it to disloge corrosion around the brake cover. Considerable airborne suspended particulate was generated when the wheel brake covers were struck, before the inside was washed. Respectfully submitted. -- - / (J Frank 0. Brown, Jr. Industrial.
