The Twilight Zone aired an episode "Time Enough At Last" starring Burgess Meredith as a bookworm bank teller who survives an H-bomb while reading inside a bank vault. See for example:

Looking at the vault, it looks genuine but the door seems to be "neutered". The lugs on the pressure bars are missing, the glass covering the boltwork is gone, and probably some of the mechanism has been removed. My best guess is they found a closed bank for filming and the door had been rendered unlockable for safety reasons.

This in turn reminded me of the SciFi novel "A Canticle for Leibowitz" where it was pointed out a fallout shelter trapped its occupants because the door was designed to open outwards but was blocked by rubble after a nearby blast.
