Text Appearing Before Image:
used in refineries for melting old lead. The work in one of the largest of this class of refineries (No. 7) is done in a large, dark, ill-ventilated, and extremely dusty room, the floor of which is covered with heaps of dross and scrap. There are no hoods over the charge door or work door, and windows in the room are relied upon to carry off the fumes. Charges are mixed here and fed in by hand, and at least once an hour the furnace man opens the work door and rakes the charge. He stands about 6 feet away but well within the fumes which escape in great clouds and eddy around the room so that they are distinctly perceptible at a distance of 30 feet. The lead flows out at a bright red heat into an unhooded kettle. There are two refineries in which an electrolytic process is used to obtain pure lead. The work in the battery room is dust free and not accompanied by risk, except such as might come from handling the lead sheets. The places where precautions are needed are at Bulletin No. 141—Labor.
Text Appearing After Image:
PLATE 11.—A SOFTENING FURNACE IN REFINERY, WITH MECHANICAL CHARGING. The pigs of bullion come down the closed chute to the charge door. In contrast to this excellent device is the carelessness which allows heaps of dusty dross to lie on the floor near the furnace. LEAD POISONING IN SMELTING AND REFINING LEAD. 43 the kettle where scrap lead is melted for the starting sheets, in casting the starting sheets, in melting up the old sheets and drossing the melting kettles, in working up the drosses in reverberatory furnaces,and above all in handling the so-called anode mud, the product of electrolysis. This wet slime or sludge is said to consist of lead, silver, and gold in metallic form, with arsenic, antimony, and copper in compounds as yet undetermined. It must be treated in reverberatory furnaces, and in preparation for this it is dried in dust-chambers. Transporting and charging this dry powder is very dangerous, and there are of course the usual dangers from the furnaces.
