BS EN 1838:2024Lighting applications. Emergency lighting for buildings
This European Standard specifies the luminous requirements for emergency escape lighting and standby lighting systems installed in premises or locations where such systems are required. It is principally applicable to locations where the public or workers have access.
Who is this standard for?
- Lighting engineers
- Electrical contractors
- Landlords, employers and any individual with responsibility for premises such as hospitals, care homes, hotels, schools, laboratories, theatres, cinemas, concert halls, sports halls, libraries, shops, museums and sports stadia
Why should you use this standard?
The overall objective of emergency escape lighting is to enable safe exit from a location in the event of failure of the normal supply. The standard outlines recommendations for appropriate visual conditions and direction finding on all escape routes with a view to reducing panic and to enable safe movement from the building plus assistance with proper shut down procedures.
Use of BS EN 1838 can help save life and unnecessary anxiety and confusion can be alleviated by strategically placed visible signs indicating the way out of a location.
