What is this standard about?
BS 5266-1 is the first in a series of Codes of practice on emergency lighting. It gives detailed guidance on the application and practice of emergency escape lighting, with a view to ensuring safety in the event that normal lighting is interrupted. The recommendations have been drawn up to encourage uniformity of application.
Who is this standard for?
The standard has been written for two audiences:
- Lighting engineers and electrical contractors who need to protect building occupants from the hazards identified by risk assessments
- Landlords, employers and any individual with responsibility for premises such as: hospitals, care homes, hotels, guest houses, colleges, boarding schools, day schools, laboratories, clinics, theatres, cinemas, concert halls, sports halls, public houses, restaurants, libraries, shops, museums, sports stadia, covered car parks, factories, workshops and warehouses
Why should you use this standard?
This part of BS 5266 promotes a wider understanding of the different types of emergency lighting systems that can be used and give guidance on how different systems can be correctly applied to different categories of premises with varied requirements.
It gives recommendations on the factors that need to be considered in the design, installation and wiring of electrical emergency escape lighting systems, to provide the lighting performance needed for safe movement of people if the normal lighting supply fails.
This standard also applies to common access routes within blocks of flats or maisonettes and gives recommendations for lighting in areas with fixed seating.
