THE INTERNATIONAL LANGUAGE OF GRAPHICAL SYMBOLS2

IntroductionAs there are nearly 7,000 different languages spoken worldwide, literally speaking, it is impossible for an individual to understand and speak all languages. Starting with English, which is considered the world's most widely used language, still there are people who do not speak it. Talking is often seen as the only way of communication. However, there are times when a picture is worth more than thousand words.

The international language of graphical symbolsThe history of symbols dates back to prehistory. Ancient people used to use symbols as a form of communication. During the history, traces of ancient writings were found incised in stones, walls and other ancient scripts. Some of these prehistoric writings used to represent certain ideas and concepts include the form of repetitive symbols such as dots, lines and other geometric signs or figures such as animals, trees and other objects from nature. These writing systems take forms of pictograms, mythograms, ideograms, psychograms, petroglyphs, etc.

Eventually, all these motifs, words, signs and symbols led to development of languages and the richness of contemporary human life. Now, people use variety forms of communication. As globalization has increased the cross border flow of people all around the world, it has also emerged the need for citizens to be competent in other language – whereas, language itself carries most of the communicative burden.

There are times when written words are inadequate, and at that point the use of symbols and signs facilitates communication. The use of graphical symbols is urged by the need to provide a communication medium independent from language. The International Organization for Standardization, ISO, provides people worldwide with a coherent set of graphical symbols to help overcome language and other barriers.Standardized graphical symbols include groups of signs and symbols used for public information symbols, safety signs, graphical symbols for use on equipment and graphical symbols for diagrams and technical drawings.

While many graphical symbols are well known and easily understood, some still remain unclear and are hardly recognized by general public; partly because they are rarely being used and partly because different variants of symbols are used to convey the same message. Thus, it is essential to use the internationally accepted and standardized graphical symbols that anyone in the world is familiar with.

Safety signsBesides the important role they play in preventing accidents and injuries, safety signs are also legally required; particularly in the workplace. Safety signs have a vital special place in communicating health and safety information. Employers are responsible to ensure that all employees are aware of and understand the meaning of safety signs.

Safety signs provide information to people or instruct them through visual resemblance. They are a combination of shape, colors and a symbol or pictogram. Hence, the standardized colors and basic shapes are very important in helping to ensure that the different types of safety signs and the messages they convey are easily recognizable.

In cases when you visit a foreign country that you do not know the language, the presence of symbols makes

everything easier. For example, a board with different currency mark indicates the location of currency

exchange facilities; or plan view of knife and fork in line with each other is used to indicate the location of

restaurant facilities.
