Older electromechanical machines, slots, bingo type pinballs, and the like, be aware that cadmium was often used in the silver contacts to help prevent arcing. While most of you are probably aware of this, some newcomers may be unaware of the health effects. Cadmium and its compounds are highly toxic and exposure to this metal is known to cause cancer and targets the body's cardiovascular, renal, gastrointestinal, neurological, reproductive, and respiratory systems.
