Reuseh's letter of Kerch 8, 1979 addressed to all PGSO Area and District Managers ' Subject: Bearing Bracket Sealing (Ttte Seal) The subject letter was called to *y attention by one of our District Wanagen concerned with the possibility of Introducing asbestos Materials into the wort site atmosphere. Since the presence of asbestos requires very elaborate field procedures and protective measures, it is generally considered desirable to totally abstain from asbestos products of any kind. ' If a technical prcblaa exists and the esbestos product referred to in the subject letter is the only means of correcting the condition. I reuomtfMl that the Corporate Industrial Hygiene laboratory be consul ted for their guidance as to what steps must be taken when handling the material. Not only must we consider the application of the sealant to the Joint, the field exposure when opening a unit possibly presents a greater exposure hazard. By providing Mr. Blckarstaff with the teerni- cal data for tha subject material we can obtain his recemendation as to the desirability Of using the subject material frw a work hazard stand point. - Should the condition of any generator within the Pacific Coast Area indicate a need for the use of the asbestos based Tltt Seal, l xmld appreciate your advising me prior to shipment of the material. If this material already has bean usad within this area, I would appreciate your advising me of the particular units Involved. osmom *a// 73dV
