Kehoe: A question has developed in the minds of a number of our employees relative to the possibility of danger of lead poisoning when working in tanks which had been used for the storage of gasoline containing tetraethyl lead after these tanks had been cleaned and then tested by the Du Pont Corporation and declared lead-free by them.

Kehoe, tetramethyl lead has essentially the same toxicity as tetraethyl lead.
