The colors of the ISO 7010 safety signs are defined in ISO 3864-4. This means that in the informatively named Annex E, color names from different color systems are given as examples for the individual safety colors. The specifications are therefore not normative specifications in the proper sense, but are absolutely useful in practice.
ISO 7010 defines rescue, prohibition, mandatory, warning and fire safety signs and was published in 2012. The safety signs are based on the design criteria of the ISO 3864 series of standards. ISO 7010 was created in response to the internationalization of markets in order to convey uniform safety information in a few words or completely at the level of symbols. The aim of ISO 7010 is prevention of potential hazards to persons and the principle of a safety sign = a safety statement.
Safety signs must be recognized reliably and quickly. One way to achieve this goal is a systematic application of standardized safety signs, for example according to ISO 7010 with the compilation of safety signs, as these should be better recognized by the frequency of their application.
