Cralley of the Department of Health, Education and Wel fare reported that the in-rlant rhase of their study of the asbesios textile industry'would be completed by fall of 1967. He also reported on a meeting attended by a number of independent re searchers interested in the study of the health effects of asbestos on workers in the industry. The purpose of the meeting was to reach some agreement on the areas to be explored in order to be able to correlate the findings of the various individuals. It was decided that it was necessary to determine the answers to questions falling into two categories. Cl) those "involving public policy and control efforts, and (2) those needed to broaden th long term base of information on the Physical and chemical factors f fi brous materials as related to their interaction with minerals ~and man so that efforts to maintain safe working and living environments can be constantly re-evaluated and improved." They agreed that ansv'ers are needed to the following questions in safeguarding the worker^ health, yet permitting the benefit as bestos in today *s industrial technology: 7"rr~oo 1. What is the nature and pattern of disease in workers exposed to the different forms of asbestos fibers and how do they relate to the magnitude and duration of exposure? 2. How are the diseases and other manifestations observed in workers exposed to asbestiform fibers characterized clinical ly and pathologically, and do they differ when exposure in volves one form of asbestos or another? 35*^0 THIS DOCUMENT WAS NOT A RECORD CF PPG INDUSTRIES, INC.

GENERAL niSCTSSIOMS Rubber Aprons for Cards There was a discussion on experiences in the use of leather aprons and rubber aprons*. All companies represented have used leather aprons and found it nec essary to scratch them periodically to remove the glaze in order to retain their efficiency. One company is using leather aprons at the take-off and rubber aprons at the delivery with satisfactory success* They have found it difficult to pick up the roving with rubber aprons. However, they find that the rubber arrons on the delivery side require very infrequent cleaning and do a good job of condensing the roving. Oiless Bearingsfor Cards The possibilities of using oiless bearings on the cards to reduc or eliminate downtime was discussed. Two companies have done same re search on the matter and will exchange information. Operating Standards There was a lengthy discussion on operating standards and their ap plication, job training and employee relations problems, standards and Allocations are comparable. It was agreed that, wxth the present labor market, some flexibility has to be allowed. pBB 002T029_ 3521 I Minutes of rteeting - February 9, 1967 -2- Pamphlet - ^Method of Determining Asbestos Dust Concentration** Since the meeting in October 1966, orders for 20 copies of the pamphlet have been received: The original stock (July 1964) was - 1,030 copies Total shipments to date 268 Balance on Hand 762 copies Indications are that by July 1, 1967, approximately 300 conies will have been distributed.
