Safety signs are specifically meant to warn people to avoid a particular situation or desist from certain activity. They are meant to provide information, or give certain instructions to be followed while working. The signs use illumination, colors, text or even sounds to create awareness of danger. Their success is also quite dependent on their being placed at the correct locations.
Colors and Safety Signs
Safety signs can act to warn of temporary or permanent hazards. Safety signs can point to danger, act as warnings, request caution or give other special information. Color is largely used to increase the effectiveness of signs and their universal usage has led to certain colors being associated with specific messages. Danger signs use black, red and white colors. The danger is largely brought forward by the red color, while the black and white is used to create contrasts, so that the sign is more easily read or perceived. When only warnings are meant to be displayed, use is made of a combination of black and orange. They are meant to convey less risk than danger signs, but do indicate situations which require care. Safety and health signs use yellow and black where caution is requested of persons in the area, where such signs are displayed.
The Use of Texts and Symbols
Safety signs can also make use of texts and symbols to convey the need for caution or responsible action. Texts must be in large letters that can be read from a safe distance, which allows the persons reading them to take affirmative action. This is especially important in the case of fast moving traffic. Symbols have also gained universal usage and are very much in use along with the text. It is said that the use of symbols is more effective in safety signs as they can be read quickly in a fast paced environment and their universal usage can meet the equality and diversity requirements that play such a large role in business within our multi-cultural society.
Safety signs can never be substitutes for safe procedures, and can only help to make the person in that particular area, more careful. They remind people of possible danger and the need for taking action to avoid being affected.
