An exit sign is a device in a public facility (such as a building, airplane or boat) that displays where the
emergency exit is. Most exit signs around the world are in pictogram form, with or without text supplement. There has been a shift towards the adoption of such exit signs in the recent decade. A small minority of nations adhered to the exit signs that show the word "EXIT" (or similar in another language). Its purpose is guiding people to the closest
exit in case of fire or other emergency. The English word "exit" comes directly from the Latin word meaning "to go out." Most fire codes require exit signs to be permanently lit.
