At Computerworld on May 21, 2019 there was a Shark Tank story titled What’s the emergency? It described a control room that had several emergency shutdown buttons (like the one shown above) both inside and also on the wall of the hallway outside.
A moving crew carrying some bulky equipment came down the hall and one fellow accidentally backed into a protruding button – which cut power to the whole building.
That unintended action could easily be prevented. As shown above, the button could be flush with the surface, or even recessed. Or, it could be protected by a clear cover shield that has to be popped-up before the button can be pushed. There also are safety covers for toggle switches.
