Effective wayfinding saves lives during evacuation. How to design signage systems that people actually follow under stress..

BS 5499 and ISO 7010 Requirements Photoluminescent signs on escape routes Consistent arrow direction conventions Minimum sign sizes based on viewing distance Supplementary directional signs at decision points Beyond Code Compliance Low level wayfinding systems (below smoke layer) Floor level photoluminescent strips Tactile wayfinding for visually impaired occupants Digital dynamic signage that responds to fire location Evidence Based Design Research shows that occupants are 3x more likely to use exits with enhanced wayfinding compared to standard compliant signage alone.
