;j We have had experience with all phases of this problem with respect' to safety, and have responsibility in dealing with the safe handling/ of tetraethyl lead fluid, and it may be that we can offer some he1pful advice.

Kehoe, the drawn:- 1) There is no reason to fear the existen health from the distribution and use of leaded ga 2) Experimental evidence has indicated th absorption fuom skin contact and inhalation of va tetraethyl lead were practically negligible; 3) The lead exposure associated with the gasoline containing tetraethyl lead at service st 4) The lead exposure arising from prolong and repair of automobiles using leaded gasoline f to cause slight increase in the mean rate of arin either in a greater lead output per unit time or No increase in the fecal lead excretion has been 5) There is no reason to believe that the service and repair work involves danger from lead 6) Because of the number and variety of o exposure to lead in the garage mechanic's occupat lead exposure deriving from leaded gasoline and i conjectural.

The saturated yapor of tetraethyl lead in air atordinary temperatures contains approximately 5 age. of lead per liter' of air - a concentration Which la lethal for experimental animals after a few hours of exposure.

The lead present in this weight of sludge, as tetraethyl lead, is 1.5 grams based on the 0.006?

In the matter of the use of British Anti-Lewisite in the treatment of tetraethyl lead poisoning the situation has been somewhat beclouded by an incident that occurred several years ago.

The specific occasion for this letter arises from the correspondence vhieh I have received recently in connection vith tvo cases of tetraethyl lead poisoning treated by Dr.

For example, derma titis is practically unknown in the plants where tetraethyl lead is manufactured.

Dear Mr# Webb; In the matter of the letter of the Surgeon General asking for information in regard to the effect of tetraethyl lead in gasoline when splashed in the eyes, I can only say what I have previously said to you. .

iPublic Health Aspects of Increasing Tetraethyl Lead Content in Motor Fuel1' was not available to us, our copy of the report of the U.S.

However, it is fairly certain that the contamination originates from tetraethyl lead that has been added to gasoline and that the lead is eventually being breathed and eaten by stock and people.

It would ppear that when leaded gasoline that contain* 3 co of lead Sc used stsasurable ajaou&ts of lead are found is the flue $*#*,- but that the greater proportion of this o&m& over in the first 30 ntlnutea while the stove Is coming to temperature, ad w have further found that the lead which, passes the filter In the early minute* of running is in the form of tetraethyl lead, `fills of course does not escape into the flue g&* as it is completely decomposed in passage through the flame, but it does suggest the possibility that improvements in the .stove could be mads that would enable more complete decomposition of the tetraethyl lead while the stove is being started.
