Multi-ton iron crucibles moving on rails and chains that can seriously injure somepony in a collision, slice off a limb caught in their wheels, or completely flatten anypony underneath if they should fall. Noxious fumes from the burners and slag burn-off which can poison workers if they are not properly routed to the chimneys. Vats of molten metal so hot that even tiny spills or sprays can melt flesh right off the bone. And woe betide the poor soul who falls in and is vaporized before their coworkers in the blink of an eye."
