This sign – and the fire door it’s attached to – are definitely left over from the Olden Days. There was a time when fire doors were closed manually to protect the building when it was unoccupied. Nowadays, fire doors have to close and latch the door at all times. Automatic-closing devices allow doors to be held open for convenience, but automatically closed during a fire to compartmentalize the building. The motivation for this change may have been some tragic fires in occupied buildings that resulted in high numbers of casualties. Today’s fire doors have saved countless lives.
