The ISO symbol for "Exit".

ISO 7010 is an International Organization for Standardization technical standard for graphical hazard symbols on hazard and safety signs, including those indicating emergency exits. 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.

As of September 2022, the latest version is ISO 7010:2019, with 6 published amendments.[2] This revision cancels and replaces ISO 20712-1:2008, incorporating the water safety signs and beach safety flags specified in it.[3]
