Walk into almost any public building in Europe and you'll see the same green and red pictograms — regardless of country or language. That's no accident: they follow the ISO 7010 standard, which defines unified graphical safety symbols that are recognizable without translation.
How each sign is built
- Shape and color — defined by ISO 3864-1 (for example, a green square for evacuation, red for fire equipment).
- The graphical symbol itself — designed according to the principles of ISO 3864-3, so it's clear and unambiguous visually, without text.
The most common signs in practice
- Running man toward a door — marks an evacuation exit or direction of travel.
- Fire extinguisher — marks the exact location of a portable fire extinguisher.
- Fire hydrant / hose reel — marks an internal fire hydrant.
- Manual call point — the location of a button to manually trigger the alarm.
- Assembly point — the location where evacuated occupants gather outside the building.
Why standardization matters in practice
In an actual emergency, there's no time to read and interpret. Standardized symbols work precisely because they're recognized instantly, regardless of whether a visitor reads Cyrillic, Latin script, or doesn't speak the local language at all. That's why signage isn't an aesthetic choice — it's part of a building's overall safety system and needs to comply with the current revision of EN ISO 7010.
Sign placement isn't a standalone task — it's tied to the evacuation plan and the layout of the fire equipment itself.
