Konian - Tolado T. J. Moyer - Toledo H. J. Sabine - Granville P. Scheuerle - Berlin S. H. ThomEE - Toledo This meeting was held to bring together the various ideas concerning the best method to control dust containing asbestos at the Berlin plant Two men from H vare present who have been responsible for their dust control program The meeting was quite ccadid and the men were understandably critical of the inadequate ventilation throughout the plant They pointed out many areas which needed change and with great candidness suggested the change they would Install Install ' Engineering frca Toledo described their approach and what they had planned I indicated my concerns vere simply to lower the dust level of asbestos containing dust to be consistently below the Threshold Limit Value I pointed out this at the present ; time is 5 million particles par cubic font However the Threshold Limit Values have published 2 million particles per cubic foot as the intended change which would go into the accepted list in a year I think realistically we have to engineer to be below 2 million particles per cubic foot : 488 Memo to Record February 28 1969 n + e _ Mr. Scheuerle reviewed each aspect so that the engineers had a clear understanding as to the problem and requested that they look at these problems both from a standpoint of noise attenuation as recommended by Mr. Bradley and Dr. Sabine from our acoustical Laboratory as well as the air borne particulate This was a most effective meeting JLX Jon L.
