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.
