Feature
The revised prEN1838 states that Adaptive Emergency Escape Lighting Systems (AEELS) can now be used in all types of buildings. AEELS are advanced lighting systems designed to enhance the safety and effectiveness of emergency evacuations. Highly intuitive, these systems are designed to adapt to changing conditions and provide clear and efficient illumination
to guide building occupants to safety. Using
sensors and monitoring devices they can detect changes in the environment, harnessing intelligent control technology to automatically change factors such as escape route direction, the visibility of the emergency signage and lighting levels on escape routes.
BS EN 50172:2004 specifies the minimum provision of
illumination of escape routes and safety signs, as well as the testing requirements of emergency lighting systems for different premises.
For EN 50172, the main changes coming into force relate to inspection and testing of the luminaires and systems. In addition to current daily, monthly, and annual verification tests, a bi-annual test of emergency luminaires and externally illuminated escape route safety signs should be implemented to verify that they are undamaged and that their intended function is not impaired due to the presence of dirt, dust or visible material degradation.
In conclusion, as we approach the impending changes to British Standards governing emergency lighting, it is evident that the role of emergency lighting in safeguarding life and ensuring the smooth evacuation of buildings cannot be overstated. Staying informed and prepared for these changes is vital and a fundamental step toward ensuring the safety and well-being of building occupants in times of emergency. In this ever-evolving landscape, the importance of emergency lighting remains unwavering, providing a beacon of safety in the darkest of hours.
