One effect of the last paragraph of this published memo randum of October 24th. is that the Division Commander here has had large sign in red letters made to put up wherever gasoline containing tetraethyl lead reading; "DA1IGER-LEAD* N29491 2 over - if I am correct in my deductions, and if I am not correct, then I should like to know what steps are neceassry to take to safe guard our personnel who daily come in contact with gasoline containing tetraethyl lead.

The teeth were in fair condition, and there was no lead line.

The analytical figures that you give indicate that washing and aeration will effectively reduce the amount of lead vapor in t-he air, hut ore always has to consider the possible liberation or exposure to tetraethyl lead or its products 'when work, is actually begun.

They oorae to us from manu facturers of stoves who State that they have been requested by some one in the Quartermaster Corps to develop this, that or the other device for burning leaded gasoline* A recant inquiry from the Jiltrol Company stated that Camp Holabird was about to begin experiments on the use of activated olay for removing lead from gasoline.

March 7, 1940 Mr*Prank Greene La Crosse Auto Supply Company 123-125 South Sixth Street La Crosse Wisconsin ''' Dear Mr* Greens ; Your letter of February 14th addressed to the Ethyl Gasoline Corporation concerning your employee who specializes in valve grinding and motor work, has been referred to me and has been lying on my desk unanswered for some days because of my enforced absence from the laboratory# The problem which you raise in connection with this man is one which is worthy of consideration# It has seemed to us for some time that under certain peculiar conditions of continuous work of this kind, a man might be exposed to significant quantities of lead# We feel quite certain that such a condition would be most unusual# We have had occasion to examine a number of men in this type of work without finding any evidence of significant lead exposure, or measursable lead absorption on their part* Moreover we have never found a case of significant lead exposure among workmen of this type# However, despite the fact that this has never occurred, so far as our experience goes, I am unwilling to take the position that it could not occur# Accordingly I should be very much interested in seeing and examining your employee, if It could be arranged# This could be done by making a trip to La Crosse but both my associates and I are occupied with a number of other matters at present, and this could not be done at once# It could be done promptly, however, if your employee could come to Cincinnati# We are very much interested in problems of this sort, and we are quite willing to defray the expense which would be associated with your employee^ trip to Cincinnati# in doing this, however, I would not want to develop the idea in his mind that we have any anxiety concerning him, or that we have reason to believe that he was ill on account of lead exposure# Rather my point of view is that over a period of years we have been spending a great deal of money investigating the potential public health problems concerned with this industry, and there is no reason why we should not spend additional money - \ and effort, especially When the circumstance seems to have 1 :;*v, M7126 - 2- some useful information* Therefore, if both you and your employee were to look at this as something of an experimental study, we should be quite willing to examine him, to defray the expense of his trip to v Cincinnati, and to give him and you a definite opinion as. to the nature of his illness and also the degree to which ho has absorbed lead as a consequence of his work.

Clinically, this does not appear to ba, a case of lead poisoning.

As a matter of fact, 1 am entirely certain from our enormous body of data that it is quite impossible for individuals to absorb significant quantities of lead as the result of their contact with gasoline containing the commercial concentrations of tetraethyl lead.

In no instance wa3 the concentration or organic lead of such order of magnitude as to suggest a hazard from that source.

There is danger of exposure to tetraethyl lead in the manufacture of this material and of Ethyl Fluid which contains tetraethyl lead in high concen tration.
