Maybe those are staged but some apparently dangerous looking things can be done, and is sometimes neccessary, but it helps to fully understand exactly where current will flow from and to, and not be on that path. As an example of apparent risk, when the children were small, and before we had central heating installed, we used to take an electric fan heater into the bathroom on an extension lead - it might have been safer on a dedicated RCD socket, but the main thing was to turn it on and off from the dry end of the lead, and not touch it when in the bathroom.
The problem for the non technical risk taker is that some equipment seems to be designed almost as if to encourage unwittingly risky actions - pressure washers with a 13A plug for example, are almost bound to be unplugged with wet hands at some point.
