Dr. Francisco Grana, Beln, 105^, Lima, Peru ^3* --i CC' CD O hi N15341 Dr. Francisco Dr ifa, Helen, 1094, Lima, Peru. Dear Dr. Or aria: I have just received word from. hr. Hiaso-Gill of the associated Ethyl Company, Limited, that ire has discussed with you the carrying out of certain medical work in supervision of employees of the Government Refinery, at borritos. I assume from Ur. nisso-Gill's letter that you are willing to undertake this work. Accordingly, X am sending you u m or separate cover some information on various phases of this problem and i 3nail ask Ur. Risso- Gill to forward to you some booklets In epanish, which I have prepared for distribution to interested persons in Spanish-speaking countries. The articles are translations of publications that appear in American medical and scien tific journals. They will give you the general experimen tal background of this field and will acquaint you with the orcbloms which have arisen. briefly, your main responsibility will be to select men on the basis of their physical fitness and taeir reliability in carrying out instructions for their own protection. Pin v.ho are caroloss are d of initely undesirable, <nxl those who are unduly apprehensive are equally undesirable. what we want is a sensible, comparatively young, healthy man, who will recognize that if he conducts himself properly, he will be entirely s afe in the work he is called upon to do. after the selection of these -workmen, It will be necessary to exa mine them at approximately quarterly intervals sc as to fol low the state of their health, and also to make sure that they are doing thoir work carefully and safely. At the time the men are examined it is advisable to inspect the plant, so as to appreciate the care which is being given to details. On this account, it will be desirable for you to visit Callao, at regular* intervals, and X would suggest the desirability of examining the men at the plant If the facilities there will permit. A medical memorandum which I am sending you will outline the general purposes and tbe nature of the medical care of these men. During the period of some fifteen years in whi ch we have KET $ 0 13 a there la no reason to suppose that there will be, if the work is hone &3 it is supposed to be done. The equipment U3ed for mixing is simple in operation and entirely adequate from the point of viow of safety. If this equipment is kept in good condition and if it is operated in accordance with instructions, there is no occasion for hazardous lead expo sure. it is the primary purpose of our medical supervision to determine by the examination of the men whether they are doing the work as it should be done. If they show any evi dence of loud absorption, one can be certain that they are not following the Instruct!-ns. Under these conditions, it is necessary to bring the matter to the attention of t he management and to correct any condition which is responsi- bio for tho unsat1sfac tor. of the work. A S you w L11 see fr cno -articles supplied b,, Mr. Kisso-GIll, the re. is no a a n g e r of lea<d poisonin._ rom the handling and use of t h,e mixed qasol Ine . Therefore, the primary danger is in corinec 1 1 on w 1 1h the ha: ling and mixing of the concentrated Flu id. The re is only one other a anger which needs to r.-e considered sor Iously the lo;a-a'* eoxnp osure waich may arise in con nec u j - U a 1* th c :c an Ing of gasoline storage tants, Gmail quan tities of organic lead compounds may accumulate in the bottom of gasoline storage tank 3 OVOX* long period of tine. Men who enter those tanks to clean thorn may be exposed to those volatilo lead compounds, unless they use precautionary mea sures which we have advised. I call your attention to these procauti-ns in the back of the book of regulations, which Mr. Hisso-Gill will send to you. He will discuss these matters with the management of the plant, but it Is necessary that you should be familiar with these points, and that you should stress their importance to the management of the plant. I should appreciate It if you would acknowledge receipt of this letter and the booklets which I am sending you. Also, I should like t o hear from you from time to time, especially if there are any difficulties of any kind. Any questions which may come up in your mind should also be referred to me, since I try to keep in touch with our mealcal consultants and to keep thorn acquainted with any new developments in the field. Please accept my thanks for your willingness to undertake this responsibility. E 0013450 Cordially yours,
