Sample questions
01What is the minimum maintained illuminance level required on escape routes according to BS 5266-1?
- A10 lux
- B1 lux
- C5 lux
- D0.2 lux
Why: BS 5266-1 / BS EN 1838:2024 require a minimum maintained illuminance of 1 lux across the full width of escape routes.
02Where should emergency lighting be positioned in relation to changes of direction?
- AAt the mid-point between two changes of direction
- BAt least 5 metres beyond each change of direction
- COnly at the final exit, not at intermediate corners
- DAt every change of direction to ensure visibility
Why: Emergency lighting must be positioned at every change of direction to ensure occupants can clearly see the escape route.
03What determines the maximum spacing between emergency luminaires in a corridor?
- AThe luminaire's photometric spacing data for that height
- BNo more than ten times the mounting height
- CNo more than half the mounting height
- DA fixed 10 metres regardless of mounting height
Why: Spacing comes from the manufacturer's spacing tables or photometric design for the mounting height and the illuminance needed (for example 1 lux across the full width of an escape route under BS EN 1838:2024), plus luminaires at each point of emphasis such as exits, changes of direction and stairs.
