I was immediately reminded of the stern warnings to keep out of flooded basements until you've made sure the electricity to the house is cut off. I found[1] at least one person who died this year because of this lesser-known risk of flash-flooding (the more intuitive concern is drowning because you can't open the door due to water pressure). It's possible that it was more voltage at play, though, there are 400V lines in most German homes (electrical heating and stoves, mostly).
