LABORATORY OF APPLIED PHYSIOLOGY UNIVERSITY OF CINCINNATI COLLEGE OF MEDICINE g e n e r a l h o s pit a l July 25, 191) Mr. John Schaefer Ethyl Gasoline Corporation Chrysler Building New York, New York . Dear John: Dr. Kehoe has asked me to reply to your request for information concerning the repair of an Ethyl tank car. It would seem to us that when the oar is properly prepared by steaming, removal of sludge and chemical treatment, that the work could be carried out safely with proper protection of the workmen. This protection should include air-line respirators, clothes, gloves, and boots, of a type similar to those required in tank cleaning. The man should remove all clothes and bathe at the end of the shift or sooner if his clothing is contaminated with material from the walls or bottom. It would not seem practical to insist upon the use of impervious clothing for this operation, although a rubber apron could be worn to advantage. This repair work is a type of operation which will probably have to be carried out from time to time in the future, perhaps at rare intervals, and if you will let us know when and where the work is to be done, if at all possible one of us would like to make it a point to visit the plant at the time the work is going on. Cordially, WM: vr Willard Machie, M. D.
