March 7, 1940 Br B* Hurtado Colombien Petroleum Company Cucuta* Box 100 Colombia* South America Bear Doctor Hurtado: . I was very sorry to have missed you on the occasion of your recent visit to Cincinnati* for I should have been pleased to talk with you about various phases of our work* I am sure you obtained all of the practically useful Information from Dr* Sanders however* so that I trust your trip to Cincinnati served your purpose* / I believe you received most of the reprints of our work ishtch were available* On the other hand there was a series of articles which had been translated into Spanish* which* X believe* will be useful to you in that language* Accordingly I have sent you,under separate cover* copies of these translations* If you should find that you require additional copies of these translations* please do not hesitate to let me know for I had these articles translated primarily for the use of medical men who are concerned with this problem* 1 should appreciate it if you would drop me a note from time to time* letting me know of your progress and specially of any difficulties which may occur# Our experience in other countries in connection with the occurrence of difficulties may well be of seme value to you if such trouble should arise* In any case I try to keep in touch with what occurs in various parts of the world in this connection* It is possible that your attention was not called with emphasis to the rather serious hazards which may be associated with the cleaning out of storage tanks which have been used over a considerable period of time for the blending and storage of leaded gasoline* We have had a series of accidents In this country which have been the result of failure to carry out the regulations which we have prescribed in connection with this work* It seems that from time to time a group of workmen will Insist upon entering these tanks for the purpose of cleaning without being supplied with the necessary protective clothing# and especially with an airline hose mask* Under certain unusual oircumstmcos \ 2* * - it may happen that concentrated Ethyl Fluid introduced into the gasoline in too rapid a stream may sink to the bottom of such tanks and lie there over a period of months or years in the sludge# This happens of course, only if there is a water bottom in the tank# Subsequently when men enter such a tank to clean it, they may have serious contact with concentrated Ethyl Fluid, and they may also he exposed to relatively concentrated vapors of tetraethyl lead# All of these things can b avoided by proper attention to the regulations which we have devised and which are given in detail in the booklet of regulations which you have# I call your attention to this point as being the one thing which is most* likely to result in serious difficulties, in order that you may warn your people against this danger and urge upon them the necessity of proper precautionary measures* Cordially yours, RAKiiS r ^ FT1 7 " k5H^710* KE" 00J34a0
