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.

Dear Hugh: I am afraid that I cannot advise you to us tetraethyl lead In the case about which you wrote in your letter of April 1* I should certainly not advise the injection of tetraethyl load.

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.

Moreover, the vola tility of the lead compound is so lov, as compared with that of the gasoline, that only insignificant and practically un measurable amounts of tetraethyl lead appear in the vapor over- lying leaded gasoline.

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.

tions We should appreciate your comments and sugges- Very truly yours SW:GCL Enclosure r A REPORT OH USE sod HANDLING of TETRAETHYL LEAD by DOW CHEMICAL COMPANI, MIDLAND, MICHIGAN General -- The purpose of the following Is to describe briefly the present use and handling of tetraethyl lead by Dow Chemical Company at Midland, Michigan, end to suggest certain recommendations for sore safely handling the material* Pure tetraethyl lead is being used as one of three c&talyats in a polymerisation process designed to produce a particular plastic.

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

Regarding theexposure to tetraethyl lead, no concentrated Fluid is handled in -the engine-room, only diluted Fluid being used in testing.

Such cases have been seen only as the result of very serious exposure to concentrated tetraethyl lead.
