— Requirements for emergency escape route lighting have been amended to cover the width of the
escape route;
— Greater detail has been included for the requirements for emergency lighting of points of emphasis
and specific areas of hazard;
— Considerations for emergency lighting systems during and after a premises lockdown or prolonged
periods where power is disconnected have been added as Annex C.
This document is read in conjunction with EN 50172.
Any feedback and questions on this document should be directed to the users’ national standards body.

Introduction
Emergency lighting for buildings is provided for use when the supply to the normal lighting fails and is
therefore powered from a source independent of that supplying the normal lighting. It may provide
lighting for both safety and operational tasks.
For the purposes of this document emergency lighting is regarded as a generic term of which there are a
number of specific forms, as shown in Table 1.
Table 1 — Specific forms of emergency lighting
Emergency lighting  see Clauses 4, 5, 6 and 7

Emergency escape lighting, see Clause 4 and 5

Escape route Open area (anti- High-risk task area Local area Standby
lighting panic) lighting lighting lighting lighting

see 5.1 see 5.2 see 5.3 see 7.1 see 7.2

Safety signs including adaptive safety signs
see Clause 6
Emergency lighting can be provided by maintained luminaires and maintained safety signs when the
normal lighting is available. Maintained luminaires and maintained exit and safety signs shall operate
when the normal lighting is required but fails. (Refer to EN 50172 for further details on normal lighting
failures.)
Adaptive emergency escape lighting (AEEL) is a technique that can be used as a supplement to
emergency escape lighting and, when applied to escape routes in addition to emergency escape lighting,
can enhance their effectiveness in an emergency. These techniques are included in CEN/TS 17951.
