An illuminated exit sign tells people where to go. Its usefulness depends on being visible and unambiguous from the direction people approach. A bright sign with the wrong arrow or an obstructed sightline can undermine the route information.
Follow the escape route from the user's position
Check each decision point, including corners, changes in level and the final exit. Determine whether a wall-mounted or projecting sign is needed and whether the face must be visible from one or two directions.
Choose the symbol, arrow and text requirements for the destination jurisdiction and approved escape plan. Do not reuse a familiar sign design from another market without checking its suitability.
Size for recognition, not wall space
The required viewing distance and mounting position determine the sign format. Equipment, partitions and open doors can hide a sign that appears clear on a plan. Normal and emergency lighting conditions both matter.
Eaton's guidance on building use and emergency lighting explains that the evacuation arrangement must reflect occupants and the building. Sign selection should therefore follow the route assessment rather than a universal sign count.
Coordinate the emergency supply
Confirm the required operating mode, supply arrangement and duration. For a self-contained unit, include battery access and test facilities; for a central system, define the interface and monitoring responsibility.
A sign illuminates its message. It should not be assumed to provide all required floor-level escape lighting unless the fitting has a documented combined function and the lighting design demonstrates the result.
Include the signs in the maintenance schedule so failed illumination, damaged legends and changed sightlines are detected. A revised partition or storage layout can invalidate a previously clear view.
