Headlamp and boots are the priority. There's no telling what will have broken that you really don't want to step on.
An easily accessible headlamp and boots or other sturdy footwear are definitely a good idea. Wood frame houses can flex a lot. Windows not so much.
I also keep a
gas shut off wrench zip tied to the main valve by the gas meter on the outside of our house.
