Do you know where you water shut off is?
It is critical not only you know where it is, but that it is accessible and in good working order.
I inspect homes all the time where the water shut off is blocked with storage, behind a access panel that is screwed shut (requiring tools and time to get to). Imagine a burst pipe or other leak – water running on the floor and through the ceiling and you looking for a screwdriver – AAAAHhhh … Do yourself a favor. Find it, confirm it works and STAYS accessible..
P.S. this includes your electrical panel too !!
