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." 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 August 2019[update], the latest version is ISO 7010:2019. This revision incorporates all previous corrigenda, as well as incorporates water safety signs and beach safety flags previously specified in (the now-withdrawn) ISO 20712.
Shape and colour
ISO 7010 specifies five combinations of shape and colour to distinguish between the type of information presented.
|Sign type||Meaning||Colour (per ISO 7010)||Shape||Example|
|Prohibition sign||Prohibition||Red||Circle with diagonal line||No open flame|
|Mandatory sign||Must do||Blue||Circle||Use hearing protection|
|Warning sign||Warn of hazard||Yellow||Equilateral triangle with rounded corners||Explosive materials|
|Safe Condition sign||Safety equipment & exits||Green||Square or rectangular||Emergency Assembly Point|
|Fire Safety sign||Fire Protection||Red||Square||Fire Extinguisher|
ISO registers and lists recommended pictograms, which it calls "safety signs", on its website, ISO.org. The ISO standard provides a registered number for pictograms that have officially been made part of the ISO 7010 standard. Corresponding with the categories above, in ISO parlance, "E" numbers refer to Emergency (signs showing a safe condition), "F" numbers refer to Fire protection, "P" numbers refer to Prohibited actions, "M" numbers refer to Mandatory actions, and "W" numbers refer to Warnings of hazards.
