Introduction
Emergency lighting 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.

Emergency lighting can also be provided by maintained luminaires and maintained escape route safety
signs when the normal lighting is available. Maintained luminaires and maintained exit and escape route
safety signs shall operate when the normal lighting is required and when the normal lighting fails. (Refer
to EN 50172 for further details on normal lighting failures.)
Forms of emergency lighting and their applications.
Emergency escape lighting is provided to enable safe exit from a location in the event of failure of the
normal supply. The objective of each form within this category is as follows.
The objective of escape route lighting is to assist the safe exit from a location for occupants by providing
appropriate visual conditions and direction finding on escape routes and in special locations, and to
ensure that fire-fighting and safety equipment can be readily located and used.
The objective of emergency lighting escape routes is to be readily located and used. A multi-purpose
luminaire that provides direction finding and escape route lighting may be used.
The objective of open area (anti-panic) lighting is to reduce the likelihood of panic and to enable safe
movement of occupants towards escape routes by providing appropriate visual conditions and direction
finding. The flow of light for escape routes or open areas should be downward to the working plane but
illumination should also be provided to any obstruction.
Safety Lighting provides illumination for the safety of people involved in a potentially hazardous process
or situation.
The objective of local area safety lighting is to protect occupants who are allowed to remain in a premise
in the event of a supply failure. It is based on a safety risk assessment dependent upon the activities likely
to be performed. Additional areas of coverage and levels of illumination higher than the provision for
emergency escape lighting may be required.
The objective of high-risk task area lighting is to contribute to the safety of people involved in a
potentially dangerous process or situation and to assist proper shut down procedures to be carried out
for the safety of other people in the location.

Standby Lighting is based on operational requirements. This standard gives the definition of the term
and describes the principles and requirements to be complied with in context with the emergency escape
lighting.
There are techniques such as adaptive emergency escape lighting (AEELS) 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 not included in
this standard.
Much anxiety and confusion can be alleviated by strategically placed escape route safety signs indicating
the way out of a location. It is very important that exits are clearly signposted and are visible, whenever
the location is occupied.

4 Emergency escape lighting
4.1 General
To ensure that emergency escape lighting operates when it is required to meet legal requirements, it shall
be installed, tested and maintained in accordance EN 50172.
The requirements given in this document shall be maintained for the full rated duration to the end of the
design life of the equipment.
The emergency escape lighting scheme design should be based on worst conditions (e.g. minimum light
output, maximum glare limits and including an appropriate maintenance factor) of the luminaires during
operating life and should be based only on direct light from luminaires. Lighting calculations shall be
based on the rated emergency intensities data related to the Practical Emergency light source flux
according to EN 60598-2-22.
The contributions by room surface inter-reflections should not be considered. However, in lighting
systems such as indirect luminaires or up lights (used as an emergency luminaire in maintained mode)
where the luminaire works in conjunction with a reflecting surface, when using indirect lighting for
emergency escape lighting, the following three points shall be taken into account.
• The first reflection may be included in the calculation of the emergency escape lighting.
• The reflective surface shall be considered in the maintenance of the emergency escape lighting as if
it was part of the emergency light.
• The distance between the light source and the reflecting surface shall not be obstructed by any object.
Luminaires shall be mounted at least 2 m above the floor level unless a mounting height of luminaires for
lighting of 2 m is not suitable for special reasons (e.g. in outdoor areas, assembly points, places of safety,
stairways, historic buildings etc.), in which case luminaires for lighting may be mounted lower than 2 m
above the floor, provided that the protective objective is met.
The designed illuminance levels for emergency luminaires and the required luminance values of safety
signs shall be multiplied by a maintenance factor specific to the installation. Explanations of the
maintenance factor can be found in CIE 97 and EN 13032-2.
To provide visibility for evacuation purposes lighting is required in the volume of the space of the escape
routes. Signs that are provided at all exits intended to be used in an emergency and along escape routes
shall be externally or internally illuminated to indicate unambiguously the route of escape to a place of
safety. Sign requirements are detailed in Clause 5.
Where direct sight of an emergency exit is not possible, an externally or internally illuminated directional
sign (or series of signs) shall be provided to assist progression towards the emergency exit.
An emergency luminaire conforming to EN 60598-2-22 shall be sited to provide appropriate illuminance
near each emergency exit and at positions where it is necessary to emphasize potential danger or safety
equipment. The positions to be emphasized shall include those given in Clause 4.2.
If the premises operator needs to be able to redirect occupants away from specific emergency escape
routes an adaptive emergency escape lighting system (AEELS) should be used.
