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]

The standard was published in October 2003, splitting off from ISO 3864:1984, which set out design standards and colors of safety signage and merging ISO 6309:1987, Fire protection - Safety signs to create a unique and distinct standard for safety symbols.[2][3]

As of September 2022, the latest version is ISO 7010:2019, with 6 published amendments.[4] This revision canceled and replaced ISO 20712-1:2008, incorporating the water safety signs and beach safety flags specified in it.[5]

Shape and colour[edit]

ISO 7010 specifies five combinations of shape and colour to distinguish between the type of information presented.[6]

Shape and colour of sign types
Sign type[1] Meaning Colour (per ISO 7010)[7] Shape[7] Example
Prohibition sign Must not do Red Circle with diagonal line ISO 7010 P003.svg No open flame
Mandatory sign Must do Blue Circle ISO 7010 M003.svg Use hearing protection
Warning sign Warn of hazard Yellow Equilateral triangle with rounded corners ISO 7010 W002.svg Explosive materials
Safe Condition sign Identifying of safety equipment & exits Green Square or rectangular ISO 7010 E007.svg Emergency Assembly Point
Fire Safety sign Identifying of firefighting equipment Red Square ISO 7010 F001.svg Fire Extinguisher


ISO registers and lists recommended pictograms, which it calls "safety signs", on its website, 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.[8]

According to the related ISO 3864-1 standard, if a symbol does not exist for a situation, the recommended solution is to use the relevant 'general' symbol (M001, P001, W001), along with a supplemental text message.[9]

Safe condition[edit]

Crescent variant[edit]

ISO 7010 states on all symbols with an first aid cross, that it "may be replaced with another element appropriate to cultural requirements". In countries with a Muslim-majority population, an appropiate symbol is the crescent.

Fire protection[edit]




Withdrawn symbols[edit]

The following symbols were previously part of ISO 7010, but have since been withdrawn from the standard.
