I would suggest human beings are unsafe. It's human beings that put all Fukushima's 20 backup diesel generators in the basement, but put no backup diesel generators a few stories above or on stilts raised above a flood. Two backup diesel generator installed a few stories up, and none of this happens. The Dutch have put their water pump generators up a few stories for a long time. New Orleans had power for their water pumps raised a few stories pre-Katrina.
