I'm confused as to how a location can be safe enough to leave the ac rotors running but not safe enough to close down
The explanation sometimes given by pilots who operate in remote locations in some parts of the world is that the risk of not shutting down has to be balanced against the risk of not being able to re-start.

I can imagine that in a few circumstances, shutting down may not be a good idea, but I have yet to encounter these circumstances.
As you are not a professional pilot, it's unlikely that you will.
