March 3, 19*1 Mr. 0. B. Lewis nthyl Gasoline Corporation Chrysler Building New York, New York Dear 03or: I am returning to you somewhat belatedly, the draft of Mr. Rourke's proposed story for storage tank cleaning. The story itself outlines the facts in a fairly satis factory way, and we can see no conflict with the information that we have. However, the paper could be greatly improved by the inclusion of certain information that is in your hands, and I would suggest that you pass the following along to him: (1) The paper would be greatly improved by some reference to the frequency of certain kinds of accidents and diffi culties. The material that you summarized from the weekly letters, pointing out the frequency of failure of air-line respirator equipment and various other accidents within tanks, could be abstracted and classified and would be very useful in pointing cut the most common sources of difficulty. (2) Much work is now under way in attempts to clean at least the small tanks from the outside, and some mention should be made of the possibilities of use of both scraping and brush equipment, suoh as the Chicago Division has developed, or their more*recent efforts toward vacuum cleaning of tanks. These efforts need not be detailed, but it would be extremely useful to awaken interest in the possibilities of their use. (3) Some mention should be made of the disposal of sludge and the necessity for bathing at the end of the working day after the cleaning of leaded tanks. Cordially, WM:vr KE 0022542 Yiliard Machle, M.D.
