April 29,1936 Mr* Vincent; Beckman Bir-at National Building Cincinnati, Ohio Dear Mr. Becloaam In accordance with our telephone conversation I m reporting to you in writing the general ro 0 ax of our Investigation of a group.of non who have ho on engaged in insulating homes with the Eagle-Picher ir.eulating material* On our trip East we examined twenty-seven men all told in XTewark and in r?hite Plains. 'She physleal examinations, the laboratory examinations, the x-ray examinations and the analyses of the blood and oxersta of these individuals .for lead and arsenic, gave substantially negative results* The men were in a good state of health and gave no clinical evidence of lead absorption, while the toots on their excreta give findings within the rang for ncxwial individuals outside of the load trades. Vo have observed the manner in which those men work. We have made tests of the dust concentration in the atmosphere in connection with various types of work which they carry out. Under certain conditions of high dust concentration in the air, the man wear masks. Under other conditions where the dust concentration is much lower, they do not wear masks. Even under these latter conditions, how ever, their exposure to dusts is very much greater than that which could be anticipated in the case of any householder. Moreover, a number of these men have had prolonged exposure (that is for years) ad should thus give findings typical of severe and prolonged exposure. All of the above data are being put together in the fom of a reports which will be ready within two weeks. However, it is not too early to say that the essentially negative character of the observations made on these men reduce to an absurdity the claim of injury made by one who had merely lived In a house after it had been Insulated. N9604 Very truly yours. Jams EAGLE-PICHER LEAD COMPANY Men Engaged in Insulating Homes with "Eagle Insulating Material".
