Fire Exit Signs - Fire exit signs or emergency exit signs indicate the direction of the exit in the event of a fire or emergency that requires a building to be evacuated. Fire exit signs must be placed to show the route you want people to take in the event of a fire, which is effectively the shortest route to safety. They play an important role in signaling fire safety, along with fire alarm call point signs, fire extinguisher signs, fire door signs and signs for assembly points.
