Lead Poisoning in the Smelting and Refining of Lead

As the three worst features of lead smelting, the ore hearth, the blast furnace, and the bag house are the essential elements in this process, it follows that the making of sublimed white lead is an extremely hazardous occupation. In both plants bag shaking is done by hand,, and in both the packing of the light and fluffy powder is very dusty.
