fUUNTVFS - EXHIBIT CAR-16 TlLIPMOMt lion 46-OA40 FRICTION MATERIALS STANDARDS INSTITUTE, BERGEN MALL OFFICE CENTER E. 210 ROUTE 4 PARAMUS. N. J. 07652 INC. May 9, 1978 Mr. E. M. Fenner Johns-Manville Sales Corporation Ken-Caryl Ranch Denver, Colorado 80217 Dear Ed: I'a writing this based on a phone conversation I had yesterday with Mr. Harry Wagner, Chairman of our Asbestos Study Committee. Harry called about the status of our work practices booklet that we were preparing for the friction material industry. He indicated that X should send you some photographs and drawings to indicate the type illustrations ve would want in the work practices booklet. I'm suggesting illustrations based on photographs and diagrams that have, appeared in other publications including the Abt Associates draft for the Department of Labor. However, there are many problems with the Abt Associates work and X will call those to your attention in the illustra tions that I enclose. Essentially we are calling for five illustrations which I have listed as Exhibits I, IX, III, IV and V. Whether they will be in this sequence, or whether they will all be used, has not really been decided. EXHIBIT I--"Use Dust Collection Equipment When Machining*1 The Abt Associates illustration shows a mechanic holding a piece of material for grinding against a sender. The illustration of the grinder or sander is ridiculous, as people do not grind brake linings in this fashion. Rather, lined brake shoes are.fastened in a fixture, as shown by the illustrations of the two grinders below the Abt illustration. One uses a horizontally mounted motor to drive a large wheel, and the lined shoe is fed into the wheel, and the fixture is rotated to arc the lining. Beneath that illustration is one showing a vertical shaft motor with the grinding wheel driven by belts and the lined shoe is similarly fed into the grinding wheel, with controls at the front of the machine. Both of these grinders are used in brake shops. There are other types of grinders, but I think that the bottom two should be right for this illustration. Of course, exhaust pick-ups should be shown in the area where the lined brake shoe meets the grinding wheel. Hr. E. M. Fenner JohnsDanville Sales Corporation 2- - " May 9, 1978 EXHIBIT II--"Do Not Use an Air Hose for Cleaning" The use of an air hose for cleaning brakes has been a common practice and is probably still in vide use today. This is one area vhere most warnings on the asbestos hazard have hammered "Do not use an air hose for cleaning the brakes." In the upper three illustrations a mechanic is bloving dust from the brake assembly. In one case, the mechanic is using a respirator, but ve do not recommend that a mechanic be permitted to blow dust from a brake even while wearing a respirator, because he is contaminating the rest of the work area. At the bottom of that page an illustration is shown with the mechanic starting to assemble two brake shoes to the brake assembly. This is to help an artist visualize the brake which is somewhat concealed because of the poor photographs above. EXHIBIT III--"Use Vacuum or Wet Cleaning Methods for Cleaning Brakes" There are two illustrations shown. One shows a mechanic using an industrial type vacuum cleaner to clean around the brake assembly. The other shows a mechanic using a vacuum to clean brake drums. X believe that kneeling on the floor to illustrate the cleaning of a brake drum is somewhat unrealistic as the mechanic is probably not going to take this position. It might be more appropriate to show a brake drum or two on a work bench, or to show a mechanic using the vacuum on the brake assembly. You could refer back to Exhibit II for a better view of the brake assembly. EXHIBIT IV--**00 Not Sweep in Work Area--Use Vacuum Methods" The illustrations shown are self explanatory in that an industrial type vacuum cleaner is shown. The idea is to not dry sweep or brush the general work area and to favor a good high filtration industrial vacuum cleaner to properly clean the work area. EXHIBIT V--**Wear an Approved Respirator If Unable to Avoid Dust" We are asking that the type mask used in 1978 be shown rather than the type shown in some of the Abt illustrations. A worker could be shown standing wearing the mask or handling a set of brake shoes or other type illustration. The point is that we want to avoid Illustrating a mask as shown by Abt. *** ** I hope that this material can be of help to an artist in preparing illustra tions for our work practices booklet. However, it might be worthwhile to consult someone who is knowledgeable on brakes to go over the artwork.
