Floating earthing system
Floating grounds can be dangerous if they are caused by failure to properly ground equipment that was designed to require grounding, because the chassis can be at a very different potential from that of any nearby organisms, who then get an electric shock upon touching it. Live chassis TVs, where the set's ground is derived by rectifying live mains, were common until the 1990s. Exposed live grounds are dangerous. They are live, and can electrocute end users if touched.
