Refineries blowing up are pretty sudden events, so there is not a lot of warning given.

The other side of this is if you live near fuel storage or rail routes that handle large shipments of dangerous goods you just have to be aware of the risks.

You know that the owners of extremely hazardous industrial sites are not going to advertise it much, so you should be checking it out.
Then you can decide if you want to move or hang around for the major event to happen.
The major event might not be as dramatic as a fireball erupting in the middle of the night.
It might be as mundane as being slowly poisoned by them scrimping on their pollution controls.
Being downwind of a plant making nerve gas might not be good no matter how great their safety record is, and a coal fired generating station releases more radioactive material as ash than a nuclear plant releases.
