TS ISO 16069

TS ISO 16069 is the standard that sets out the design and application principles for graphical safety signs used in safety way guidance systems. In practical terms, it addresses how visual components are combined to make escape routes easier to recognise and follow. The document provides general principles applicable to both electrically powered and phosphorescent components, and it also points to the main factors involved in selecting the use environment, materials, layout, installation and maintenance.

What a safety way guidance system means in practice

From a general technical perspective, a SWGS is a visual guidance arrangement intended to make an escape route more legible independently of normal lighting. Symbols, linear guidance elements, boundary markings and related visual cues work together so occupants can identify the direction of travel, the continuity of the route and key changes in direction more quickly. Electrically powered elements and phosphorescent elements serve the same overall purpose, but they differ in visibility duration, dependence on energy supply and sensitivity to environmental conditions.

What this standard covers and what it leaves outside its scope

• Design and application principles for safety way guidance systems.
• General principles for electrically powered and phosphorescent components.
• Supportive information for environment selection, material choice, layout, installation and maintenance.
• It does not cover risk assessment; different risk conditions may require different layouts and SWGS types.
• It does not include special considerations for tactile or audible components, or requirements for high-mounted emergency escape route lighting.
• It is not to be used for ships subject to International Maritime Organization regulations.

In use, this standard serves as a common technical reference for coherent route guidance rather than as a catalogue of individual signs. That distinction matters in complex buildings and public spaces, where the effectiveness of the system depends on consistency, placement and overall legibility as much as on the performance of each visual element. TS ISO 16069 provides a shared framework for other ISO and IEC committees developing SWGS for their own specific applications.
