C 0 p n/ _ *-ww.^ ---*--: February 3, 1945 Mr, F.R. Miller, Chief Chemist Aluminum Company of America Niagara Falls, New York Dear Mr, Millers The results which you submitted regarding the comparative amounts of dust and gas found in the pot room are most interesting and in general agree with the results found in another reduction plant. The work you have done with the eleotrostatio precipitator is suffic ient to give the general information which we needed, I would greatly appreciate it if you would express the electrostatic instrument to the following addresst Sanitary Engineer (R) Harry E, Seifert Division of Industrial Hygiene Bureau of State Service, D, S. Publio Health Service Bethesda 14, Maryland There will be some additional samples needed in the pot room but those may be obtained by the standard impinger. In the near future, I will write again to discuss the remaining program whioh will embrace, in addition to the pot room study, operation which were previously considered, I would prefer delaying the dust oount until such time that I can be present to help in their determination, Especially since it will be neoessary to obtain a microscope * for this purpose. It is probableo that the miorosoope can be made available from my offioe. " At the earliest possible date, I will arrange to ' come up for a general diaoussion of the program, ; j- - ' .
