Re:Two words: tinned leads (Score 1)

Lead solder paste does rub off on your skin, and even lead-containing jewelry that was intended to be jewlery can be hazardous, especially to children who may handle it excesively or place it in their mouth. Coated electronic cabling that is meant to be handled by consumers (such as Christmas Lights) usually comes with a California Prop 65 warning that you should wash your hands after handling it! I would treat computer equipment, especially printed circuit boards and coated cables the same.
