Iiehoe, (Dept, of Physiology), College of Lledicine, University of Cincinnati, Cincinnati, Ohio, U.S.A. \ Dear Dr. hence, Meaning of Storage Tanks, Colonel Thenault has just reported to me an incident which he recently observed at the Standard' refinery at Port Jerome. He noticed that a storage tank was being cleaned and the men were `working on the vsalls above the floating roof which -was at its lowest position. Colonel Thenault reports that the men were wearing the complete regulation clothing but were not using air line gas masks. He says "instead they had a hood, with eye glasses and a kind of filter opposite the mouth. It is a contraption used in lead oxide industries". ' I would appreciate, your views on this matter and just wondered whether it would be permissible to adopt this-method, say, with an approved canister mask, the canister of which embodied a "particulate" filter as well as an activated charcoal bed. ' In this case at Port Jrme Colonel Thenault reports quite definitely that when the men were working below the roof they were equipped with the air masks, but it xvas rather_difficult to transfer the apparatus to the open space when they were working on top of the roof. Yours very truly, kT 0015329 H
