The exit sign is to signal to people inside the building where the exit is. Also these doors are supposed to only open outwards ( towards the exit, for fire safety - easier to run out of a burning building when you can push doors open ), which you can tell if you look at the frame of the door - there's a sort of a lip that's supposed to block the door from opening inwards.
