In view of my long experience with the practical problems cf the is ad industries, inc-Lading those of the tetraethyl lead industry, with which I have worked since its origin, as Medical Director of Ethyl Corporation, and as the Chief Consultant to Ethyl Export Corporation and its successor, the Associated Ethyl Company, Ltd, as well as my familiarity with the medical and scientific work of colleagues in many countries, I should know a fair amount about lead, including tetraethyl lead, its use and its potentialities for harm.

$ the remissive amount of tetraethyl lead in gasoline.

FOR USE AS A MOTOR FUEL ONLY CONTAINS LEAD (TETRAETHYL) Containers of treated gasoline sold to the general public shall be labeled: FOR USE AS A MOTOR FUEL ONLY CONTAINS LEAD (TETRAETHYL) Treated gasoline is intended and sold only as a motor fuel and for no other purpose.

CONTAINS LEAD (TETRAETHYL) AND IS TO BE USED - AS MOTOR FUEL ONLY, NOT FOR CLEANING OR ANY OTHER USE.

Kehoe, Kettering Laboratory, College of Medicine, Cincinnati 19, Ohio, He i3 an outstanding authority on the safe handling of lead tetraethyl and can give you a much more authoritative answer to your question than I can.

Kehoe believes, and others present agreed, that changing the wording on pump markings from LEAD (tetraethyl lead) to another form which would cover both TEL and TML was not a problem of immediate importance since the same cautions concerning use of the gasoline will apply and both compounds contain lead.

Consequently it was to be expected that gasoline blended 471th a minute quantity of Ethyl Fluid (essentially a mixture of tetraethyl lead, and ethylene dibromide) when widely distributed as a motor fuel, should be employed as fuel for lamps and stoves and also as a cleaning agent unless people could be induced to choose other gasolines for such purposes, Accordingly all pimps and containers from which such gasoline has been dispensed have been marked so.as to indicate that the product contains tetraethyl lead, and that it is intended for use as a motor fuel only.

From a hygienic point of view there are very definite advantages to the use of small quantities of gasoline in flushing drums, as this will result in the displacement of a smaller volume of air saturated with tetraethyl lead.

If there is any refluxing action, it would appear the higher concentrations of tetraethyl lead would appear immediately adjacent to the walls of the tank.

The following men have been involved in the tank clean ing, end are listed in the estimated approximate order cf exposure to tetraethyl leads " '' ` ' end It would appear that.

Actually the absorption of tetraethyl lead even in the manufacture of the product has never given rise to peripheral neuritis.
