(Conoco) Interoffice Communication To T. H. Martin From J. A. DeBernardi ate September 19, 1975 subject VCM Exposure - Refinery Dockmen Attached you will find information related to the subject exposures for the loading of the VCM ship "Fernwave" and "Sigurd Jorsalfor." We continue to see wide fluctuations in dosimeter results related to the connection and dis connect of the loading and vent hoses used in ship loading. A review of these results could indicate that when procedures for purging and clearing of hoses are followed to the letter, a low exposure is attainable. Again, I would urge that attention be given to assuring the published procedures are used by all dockmen related to ship loading operations. 0. A.
