Control of exposure to inorganic lead fumes and lead-bearing dusts:- The handling of inorganic lead compounds in various stages of the manufacturing operations involves opportunities for exposure to fumes of molten metal,and to dusts of lead compounds and lead-bearing wastes and slag0 (Certain of these materials, such as sludge from reaction vessels,may also contain lead tetraethyl.

This statement is undoubtedly correct, except for the possibility that in our recent developments at the White Lead Plant there is indicated the possibility that an unrefined lead anode might be used as a source of lead, and there by result in a cheaper eource of lead acetate.
