A safety feature found in all enclosed public premises which is accepted and practiced by all countries is the compulsory installation of Exit Signs for all emergency escape doors and exits within the premises. This compulsory feature ensures that people trapped in a building during an emergency will not have a problem locating the escape route.
Designs of the exit sign have not evolved much over the years simply because there is no need and no room for change in the design. The words, “EXIT” has become a universally accepted word that even a person who do not understand English will know what the sign stands for. Of course some countries do include their own language in the signs for the convenience of their own people.
Although design and looks have never changed, technology has paved way for the sign to be made effective and longer lasting for the users.
