The practical impetus for these investigations, as well as their economic justification and support, came out of certain problems posed by the introduction and use of tetraethyl lead as an antiknock additive in automotive gasoline.

In this connection, we coded the records of workers potentially exposed to certain hazardous substances, such as tetraethyl lead, asbestos, benzene, noise, and so on.

' * 1tilth reference to the inclusion of certain information with respect to the-manufacturing of tetraethyl lead and Ethyl Fluid in the operating manual for safety engineers, h a v e a .suggestion to offer to which 1 would like to have your reaction* .

What I am driving at is that you might undertake to handle this job for a time and at the same time give such advice and help a3 might be required by this new tetraethyl lead manufacturing group If you would even consider seriously this problem, enough to take a trip to L03 Angeles and to discuss It with the appropriate peop I should be glad to urge them In tills direction.

.\ \ < \ ' / * We set up experimentalN^ilte^s here at the plant and found that we could successfully filter the sludge aadNredover the liquid part, diluted with kerosene, in which there was a high/4 >ereentagexpf\tetraethyl lead (between 20% and 30$), However, we have some regard 'to handling the job in this manner when it comes to fWi&\ work, in which th equipment is mounted on a mobile unit with the facilities nob, b'ei^g) quit as ideal as they would be on a stationary unit such as we eohMAnstallN^>fene plant.

As you perhaps remember, we sold Ethyl the process they practice, an ethylene-chlorine route with by-product HC1 utilised in tetraethyl lead operations.
