Guidelines for forming communication signs in the area of safety

Global age that we live in belongs to signs as organized Information and Communication systems. In spite of the standards of communication, traffic and related signs, there is no unique nomenclature of signs. The term “sign” and its meaning are differently interpreted in the literature. By analyzing the terms “sign”, “picture” and “symbol” in the communication process, this essay demonstrates the problems that result in different interpretations of the same term by different authors. That problem can lead to unforeseeable consequences in the area of safety and protection. So as to achieve uniformity of signs for all participants in the communication process, this essay suggests guidelines for designers who form signs. Making a concept of a sign on the grounds of simple structure (code) represents a starting point. Guidelines that refer to perception, information, comprehension and behaviour of people are elaborated with regard to the sign or signs shown, as a whole system, throughout the four phases of message reception.
