Asbestos Health Seminar: The Seminar on October 2, 1968 was attended by all members or the committee and the topics presented there-in w re subsequently discussed at the committee meeting. Bausch tc Lomb Automatic Dust Counter: Mr* J.P. Wronski gave a report on the tests that were conducted at the Raybestos-Manhattan plant in Manhelm,Pa. The attempt to find a correlation between the Impinger and the Bausch & Lomb Dust Counter lead to the conclusion that little correlation between the two instruments exists, particularly in regards to large particle size as well as in areas of high dust concentrations. This phenomenon is due to the low trapping velocity of the Bausch & Lomb Lust Counter, which is therefore not to be con sidered as a replacement for the Impinger. However,the Bausch & Lomb Dust Counter has proven its feasibility as an excellent monitoring device. Mr. C.L. Sheckler reported on the Membrane-Filter Method and will present a paper on that method at the next meeting. Dust Control in the Manufacturing Process: Equipment designed for tE~ reduction of dust in the various operations of textile manu facturing was extensively discussed: L.

Balloonlesa spinning and twisting. 6, Wet weaving One member company reported on a balloonless spinning frame based on the woolen system. Balloonless spinning seems to be desirable inasmuch as the absence of a balloon results in a much lower dust count. Woolen type spinning frames operate usually at a considerable higher spindle speed than those now being used in the asbestos tex tile Industry. As a result broken ends will stir up a great deal f dust. It is therefor lmperativ that the spindl will atop as soon as an end breaks. The manufacturer of the spinning frame has designed an automatic spindle stop motion and is at present experimenting with such a device, which is similar to the one already being used on balloonlM. twisting fraaaa. ?, (eontlnu,d) Page-2Minut s - Air Hygien & i-Ianufacturlog Committ e - continued: It la hoped that top management will agree to an open exchange of health safety ideas, including designs, plans, photographs and visitors in areas of mutual interest in regards to the reduction r->, r (if ever possible) total elimination of dust in the manufacturing - >Vj process. The members of the committee agreed to have technical infer- . J nation concerning health safety practices on hand at the next meeting " Members of the committee stressed the point that dry weaving of . asbestos cloth presents one of the greatest health safety problems in the production of asbestos textiles. To achieve the tentative : . TM ACGIH threshold limit values of 2MFPCF of air or the alternate, 12 fibres per ce-5 mlcrons+, engineering asbestos dust abatement ; in the dry weaving process is,it appears, an impossible taaic. Wet' * ; ; * w aving throughout the industry, however, will achieve tremendous c strides towards accomplishing' the standards recommended by the r:; `Jj United States Public Health Service and the American Conference of^ Governmental Industrial Hygienists,' 7" O OJ O It is also essential to produce and manufacture a product that will provide the fabricator and user maximum health safety. Again7' ' -5 this can only be accomplished by the process of wet woven doth, This material (wet woven cloth) is less dusty and therefore less hazardous. The Air Hygiene- &' Manufacturing Committee respectfully urges 1mm d- iate action by the Board of Governors to coordinate this matter with all ATI standing committees and follow up with specific r commendation for Industry-wide action.

With this In mind, ve obtained a roll of Japanese cloth and asked the Technical Committee to arrange phya* leal tests on It by each company. At this time we wish to expr as our appreciation to the Technical Committee under the leadership of John Hawkins for the report on the results of this testing. The test results of each company were sent to John Hawkins who compiled and submitted them to this committee. In general, the physicals were standard. However, they do reveal two areas whleh we feel could b exploited in the. market. Despite the faot that they have a high asbestos content-ASTM Grade "A"--it was reported that they failed t pass a standard flame test. Members felt that this was because they (the Japanese) used acrylic fibers as a carrier. The cloth also had a relatively poor warp tensile. This was particularly revealed and emphasized In the heat aging test whereby the residual tensiles aft r heat aging were decidedly inferior to standards maintained by all member companies. In addition, one company was able to determine that the Japanese seemed able to use shorter fibers In their cloth than we in this country. This contributes to their lower costs but, in addition, causes lower tensile strengths. Copies of the report were given to member companies in attendance and copies will be sent to those companies who were unable to attend. It was decided that no collective action would be taken as a result of these tests but each member can use the report as he sees fit. W feel that the cloth does not represent an economic purchase in relation to its projected life and that the data can be helpful in proving this premise. __ _ (continued) THIS DOCUMENT WAS NOT A RECORD OF PPG INDUSTRIES, INC.
