Hood (2 ) - January 31, 1957 manufacture of tetraethyl lead.

Van Hartesveldt of Thompson Products Company I told him of the results obtained in your Laboratory, both on the matter of the evaporation and selective absorption of tetraethyl lead by suspended material.

At the same time this is done, arrangements can be made to have lead analyses made in connection with your work.

Of course, .his hands were covered with lead oxide, and to my amazement, the first- thing lie did when lie came down off the catwalk was to take an orange out of his lunch box which lie started to peel ami cat--probably .one of the most effective ways to get' lead poisoning

Th ere is also the hazard o f later exposure to either interm ediate or end products o f the reactions of decontaminants on tetraethyl lead ( T .E .L .)

This is equally true of the two articles on "An Appraisal of the Load Hazards Associated with the Distribution and Use of Gasoline Containing Tetraethyl Lead.

First, we need to know whether there are any conditions under which unchanged tetraethyl lead can escape in the exhaust gas.
