For our own purposes in the tetraethyl lead industry we do not regard the conditions as satisfactory if the lead concen tration is in excess of 0.75 of lead per 10 cubic meters of air.

Automobile gasolines are not permitted to have more than 3 c.c. of tetraethyl lead per gallon, and at this concentration or even a little higher, the opportunity for lead absorption is negligible, under the ordinary conditions of commercial handling.

Public Health Service to the use of 4.6 c.c. tetraethyl lead in aviation gasoline.

. :: Our Manufacturing Department fools rather strongly that Tetraethyl Lead shipped for purposes such as these should be colored with an oil soluble dye in sufficient quantity <v> give the liquid a characteristic sna.de.

I think it is somewhat misleading, and since this is the onlyhazard from tetraethyl lead that goes beyond the manufacturing and .mixing plants, it would be better,in m y opinion, if such cases were referred to under some such heading as "cleaning gasoline storage tanks".

'Jith reference to our experience, I should point out to you that the lead exposure associated with the cleaning of gasoline storage tanks, if such occurs, is a matter of absorption of tetraethyl lead or its organic decomposition products.

Kather, the evidence of lead absorp ti

I believe the tetraethyl lead area has a maximum approved specification of 0.002 milligrams of lead per cubic foot of air about the area.
