ISO 7010 is an International Organization for Standardization technical standard for graphical symbols on hazard and warning signs, including those indicating emergency exits and safety signs. It uses colours and principles set out in ISO 3864 for these symbols, and is intended to provide "safety information that relies as little as possible on the use of words to achieve understanding."[1] It is distinct from the Globally Harmonized System of Classification and Labelling of Chemicals specified by the United Nations to standardise hazardous material classification and labelling.
