There was no history of previous exposure to lead and only illnesses were typhoid in childhood and influenza in 1919.

If, however, the iron has been colored with a substance such as lead oxide paint, the fumes will then contain lead and lead poisoning from this source is rather frequent. .

Myrick, assistant superintendent of the refinery, agreed that the tank need not he cleaned* Dr* Myrick*s attitude was that as long as the operation was perfectly satisfactory it would be unwise to meddle with the system* Considering the very large amount of fluid used at that refinery, we feel sure that a certain amount of sludge is continually being pumped from the tank to the gasoline storage tanks* Since we are now considering plans for future operation of the tank cleaning unit, we are endeavoring to formulate a policy on cases, of this nature* In this connection we are greatly interested in your opinion, especially as to the safety angles involved* In discussing this question we think it advisable to note that before the crew begins the actual cleaning of the tank they have it washed with gasoline to remove as much as possible of the residual-fluid* This procedure undoubtedly intro-- duces sludge directly to the gasoline system* Xt is one of the steps in the general procedure approved by Dr* Maehle, Dr* Sehradin, .M Walters, TomHonan and others at the time of the first job in Baton Rouge* Some of us feel that lead ethyl sludge should he confined as closely as possible and should be removed from the fluid storage tank before there is any chance of its being pumped to the gasoline tanks* Others hold the opinion that, sines the company insists upon very strict regulations in the cleaning of tanks which have held lead-treated gasoline, the small quantity of lead sludge introduced along with the fluid would not increase the hazard* They feel that fluid storage tanks should not he cleaned until the amount of sludge present is large enough to interfere with the operation of the fluid system* KE 0000797 Page 2 July 8, 1936 It is evident that if we adopt the attitude that tanks should be cleaned before there is a possibility of any of the sludge being pumped into the gasoline system we shall have to make our activities in this field much more ex tensive than they have been in the past year* On the other hand if we assume that there is no danger in allowing the sludge to settle out in the gasoline tank we should curtail our activities so as to clean only those tanks where the ac cumulation is very large or tanks which are, being withdrawn from service* In this regard it is the opinion of the men of the crew that a great deal more sludge than was removed from any tank could accumulate before the operation of the system would be impaired* We are quite eager to get an expression from you as to the osapfeertaytiofnasc*tors involved so that we can adopt a uniformpolicy for our future 0:W K f 0000798

Legislative proposals recommended "POISON" or "UNSAFE" labels on paints containing lead.

Haggard*s testimony could be perhaps summed up by stating he believed in spite of your tests and your study of human beings that the mere fact that you did not find lead did not necessarily mean lead was not present as a result of exposure to ethyl gasoline.

The Ethyl Gasoline Corporation Chrysler Building New York, New York j Gentlemen: One of our employees has contracted a form of poison which his physician calls "Lead Poisoning."

-on arises at to where the lead would go* "he chief Chemist of one of the oil eorv-anios here in town, advised ns that sometime ago he ran some tests regarding ths fractional distillation of leaded gasoline and obtained the following results, A liter sample of 3 cc concentration was made up and this was out in 10 fractions of 100 cc oach, The first fraction came over with a concentration of ,03 cc/gal the second about ,16 cc/gal and bo on up to the last fraction which contained about 9 cc/gal, from this it Indicates that with slow evaporation as we might get in the above mentioned car,practically all of the lead would remain in the rust and scale in the bottom.

On the first floor of the alloy building four out of the eight ob servations show an amount of lead dust which is above the per missible level.

The occasional high result indicates that some of these men have absorbed fair amounts of lead, and that there is still some considerable ex posure.

I must say* however, that I feel1the importance of getting this information into scientific literature* It is of the utmost consequence that real data he available for scientific men as to the extent of absorption of tetra ethyl lead and as to the extent, In consequence, of the hazard arising from the handling of compounds containing tetraethyl lead.

In fact 1 should be surprised if certain of the men did not show evidences of lead absorption at present despite their brief exposure.
