/ Wil min g t o n 98, De l a w a r e ORGANIC CHEMICALS DEPARTMENT PETROLEUM CHEMICALS DIVISION yr' .of July 3, 1961 Hr. D. L. Allen Asst, General Traffic Manager J. S,, Dept, of the Interior The Alaska Railroad P. 0, Box 7-2111 Anchorage, Alaska Dear Hr. Alien: Your letter of Hay 23 has been referred to tae for handling. Generally, we recommend against coverting containers that have bean used for transportation of leaded gasoline into service for edible products destined for either animal or human consumption. While we generally recommend against it, they can, by ex tremely thoroughly sandblasting, plus at times chemically flushing with acids, be uadci safe for such-use". We cannot'say that sandblasting and/or chemmcal cleaning-will necessarily render them safe for such service, as we are in no position to know how thoroughly such work is done'. Therefore, in the final analysis the only way to be sure that the decontamination has bean adequate is to complete the cleaning, fill the container with the product to be handled, sampling and analysing it to determine whether there is any significant lead contamination. If you want additional information on this subject, we would. refer you to the Kettering Laboratory of Applied Physiology, University of Cincinnati, Cincinnati, Ohio, attention of Dr. Robert A. Kehoe. Dr. Kehoe is the outstanding authority iti the country on 'matters of this kind. Very truly yours. 3.- <3. ORAIME BGCnalm bcc: Dr. Robert A. Kehoe B. G. Crane Manager of Operations 0020184
