When is Emergency Lighting necessary?
As noted in HM Government publication Fire Safety Risk Assessment, emergency escape lighting system should normally cover the following:
- Each exit door
- Escape routes
- Intersection of corridors
- Outside each final exit and on external escape routes
- Emergency escape signs
- Stairways so that each flight receives adequate light
- Changes in floor level
- Windowless rooms and toilet accommodation exceeding 8 m²
- Equipment which would need to be shut down in an emergency
- Areas in premises greater than 60 m²
It is not necessary to provide individual lights for each item above, but there should be a sufficient overall level of light to allow them to be visible and usable.
