Melanchthon:

They [the generators] must be located in safe places and well protected, and that includes the diesel fuel storage tanks and supply lines, the air intake system, the electric and/or compressed air starting devices, the batteries, the engine cooling system as well as the electric and electronic devices that are supposed to automatically start them and connect them to the pumps whenever there is a power shortage and to pilot them. So if they were flooded, there was no chance they could run for long.
