July 2 3, I9I4JL* Dr. Francisco Dr rfa, Be Ion, 10 C4, Lima, Teru. Dear Dr. Granai I have just received word from hr. itiaso-Glll 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. 1 assume from hr. nlsso-Gill's letter that you are willing to undertake this work. Accordingly, X am sending you urn or separate covex* some information on various phases this problem and a 3nail t to forward to you some booklets In Spanish, 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 orebioms which have arisen. briefly, your main responsibility will be to select men on the basis of their physical fitness and fcneir x*eliability in carrying out instructions for their own protection. ivL.n v.ho aro caroloss are d of Initely undesirable, ^nd. those who aro unduly apprehensive are equally 'undesirable, what we want is a sensible, comparatively young, healthy man, who will recognise that if he conducts himself properly, he will be entirely s afe in the work he is calls d upon to do. after tho selection of these workmen. It will be necessary to exa mine them at approximately quarterly intervals so as to fol low the state of their health, and also to make sure that they aro doing their work carefully and safely. At the time the men are examined it is advisable to inspect the plant, so as to appreciate tho 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 tho desirability of examIntog 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 which we have f<E" 0013449 2 maintained the supervision of mixing plants of this type several thousands of men in various parts of the United States and Canada, have been under our supervision* There have been no cases of lead poisoning among these men, and there la no reason to suppose that there will be, if the work is done as it is supposed to be done. The equipment used 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 absox'ption, one can be certain that they are not following the .instruct!-ns. Under the.se conditions, it is necessary to bring the matter to the attention of t he management and to correct any condition which is responsi ble for the unsatisfactory performance of the work. . i U j'v will see from tne articles supplied by Mr. His30-Gill, there, i no aanger ;f lead poisoning for.om the handling and use of1 he mixed tasoline. Therefore, the primary danger is cormec c on ie hin x. 1 -,r ? >\ ti * X t/ij. iling and mixing of the concentrated flu JL d The re is only one Oti ier anger which needs to r-e considered ser iously j I. hii, >. ie 1 cad eoxx.posure welch may arise in c on- nec 1 th** ? **r U J.Oil * * c : 0 an in2 of gasoline storage tanks.

I call your attention to these precautions in the back of the book of regulations, which hr. 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 to 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 meulcal consultants and to keep thorn acquainted with any new developments in the field. Tlease accept my thanks for your willingness to undertake this responsibility. E 0013450 Cordially yours. Habert A. Kehoe, i:i. 1)
