National foreword This British Standard is the official English language version of EN 50172:2004 and implements it as dual numbered British Standard BS 5266-8:2004. This part of the BS 5266 series partially supersedes BS 5266-1:1999, Emergency lighting. Code of practice for the emergency lighting of premises other than cinemas and certain other specified premises used for entertainment, which is currently under revision to remove requirements conflicting with EN 50172:2004 as follows. BS EN 50172:2004 specifies requirements whereas BS 5266-1 is a code of practice giving recommendations. The requirements of BS EN 50172 alter the duration period and frequency required for self-contained luminaires (see 7.2). A number of the requirements which are given in BS 5266-1:1999 are expanded, particularly the size of open area that requires emergency lighting and the procedures to reduce the impact of the failure of any single luminaire. Appropriate product standards are also identified. Compliance with this standard will assist users in meeting the requirements of the Workplace Directive, the Construction Products Directive and the forthcoming Regulatory Reform Order. The UK participation in its preparation was entrusted by Technical Committee CPL/34, Lamps and related equipment, to Subcommittee CPL/34/9, Emergency lighting, which has the responsibility to: —
aid enquirers to understand the text;

Scope
This European Standard specifies the provision of illumination of escape routes and safety signs in the event of failure of the normal supply, and specifies the minimum provision of such emergency lighting based on the size, type and usage of the premises. This standard relates to the provision of electric emergency escape lighting in all work places and premises open to the public. This European Standard does not cover private domestic premises but its provisions are applicable to common access routes within multi-storey dwellings. This European Standard is also applicable to standby lighting used as emergency escape lighting. There are emerging way guidance techniques that, when applied to escape routes in addition to conventional emergency lighting luminaires, can enhance its effectiveness in an emergency.

Emergency escape lighting
4.1
General
The purpose of emergency escape lighting is to ensure the lighting is provided promptly, automatically and for a suitable time in a specified area when the normal power supply to the normal lighting fails. The installation shall ensure that emergency escape lighting fulfils the following functions: a)
to illuminate escape route signs;
b)
to provide illumination onto and along such routes as to allow safe movement towards and through the exits provided to a place of safety;
c)
to ensure that fire alarm call points and fire equipment provided along escape routes can be readily located and used;
d)
to permit operations concerned with safety measures.
Emergency escape lighting shall be activated not only on complete failure of the supply to the normal lighting but also on a localized failure such as a final circuit failure. Emergency escape lighting is not designed to enable normal operations to be continued on the premises in the event of failure of normal or standby lighting. Full details of levels and measurement of illuminance and adaptation are specified in EN 1838 and EN 13032. The wiring rules of HD 384 / HD 60364 shall be complied with.
4.2
Identification and luminance of emergency exit signs
Where direct sight of an exit is not possible and doubt may exist as to its location, a directional sign (or series of signs) shall be provided, placed such that a person moving towards it will be directed towards an emergency exit. An exit or directional sign shall be in view at all points along the escape route. All signs marking exits and escape routes shall be uniform in colour and format, and their luminance shall comply with EN 1838. NOTE Maintained exit signs should be considered for applications where occupants may be unfamiliar with the building.

4.3
EN 50172:2004
Escape route lighting
The objective of escape route lighting is to enable safe exit for occupants by providing appropriate visual conditions and direction finding on escape routes and to ensure that fire fighting and safety equipment can be readily located and used. 4.4
Open area (anti-panic) lighting
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 2 finding. It is used in areas of undefined escape routes in halls or premises larger than 60 m floor area or smaller areas if there is additional hazard such as use by a large number of people. NOTE Condition BD3 or BD4 of HD 384 also defines areas that require emergency lighting.
4.5
Emergency lighting for high risk task area lighting
The objective of high-risk task area lighting is to ensure the safety of people involved in a potentially dangerous process or situation and to enable proper shut down procedures for the safety of other occupants of the premises. 4.6
Standby lighting
If standby lighting is used to provide emergency escape lighting, the installation shall comply with the provisions of this standard and the appropriate product and wiring standards.
5
Emergency escape lighting system design
5.1
Plan of premises
In order to ensure that the emergency lighting system is engineered in accordance with EN 1838 plans showing the layout of the building and of all existing or proposed escape routes, fire alarm call points and fire fighting equipment and indicating the positions of all structural items which may offer obstruction to escape shall be provided before commencing system design. 5.2
Failure of normal supply to part of premises
Emergency escape lighting shall operate, in the event of failure of any part of the normal lighting supply. Non-maintained and combined non-maintained emergency luminaires have to operate in the event of failure of a normal lighting final circuit. In all cases, arrangements shall be made to ensure that local emergency escape lighting will operate in the event of failure of normal supply to the corresponding local area. 5.3
System integrity
The provision of highly reliable emergency escape lighting is essential. The illumination by the emergency escape lighting system of a compartment of the escape route shall be from two or more luminaires so that the failure of one luminaire does not plunge the route into total darkness or make the directional finding effect of the system ineffective. For the same reason, two or more luminaires shall be used in each open area (anti-panic). NOTE It is not normally possible to cater for an interruption of the normal lighting due solely to the failure of an individual lamp, consideration should therefore be given to methods of eliminating any probable hazard which might arise due to the failure of this lamp.
EN 50172:2004

Specific areas requiring emergency lighting
Where national regulations do not apply, the provisions of emergency escape lighting given in EN 1838 cover the routes and locations detailed in 4.2 to 4.5 of this standard. Other areas of hazard or areas that may need access in a normal lighting failure also require emergency lighting and are defined in 5.4.1 and 5.4.2 of this standard. 5.4.1 External areas in the immediate vicinity of exits To assist dispersal to a place of safety, the external areas in the immediate vicinity of final exits should be illuminated in accordance with the illumination level for escape routes given in EN 1838. 5.4.2 Lift car Lifts present a problem because the experience of being confined in the dark within a small space for an indefinite period is not only unpleasant, but may cause harm to those who are nervous or suffer from claustrophobia. Emergency lighting as specified for open area (anti-panic) lighting in EN 1838 shall therefore be fitted in lifts in which persons may travel. The emergency lighting can either be selfcontained or powered from a central supply in which case a fire protected supply will be required. NOTE For further guidance refer to EN 81-1.
5.5
Emergency escape lighting equipment
5.5.1 Luminaires Emergency escape lighting luminaires shall be designed and constructed in accordance with EN 60598-2-22. They shall be selected to be appropriate for their location. NOTE If used in areas with risk of explosion, the luminaires shall comply with the relevant standards and the 94/9/EC Directive.
5.5.2 Central power supply systems Battery powered central power supply systems shall be designed and constructed in accordance with EN 50171 and the battery safety requirements of EN 50272-2 shall be complied with. Reciprocating internal combustion engine driven alternating current generating sets: emergency power supply to safety devices shall be constructed in accordance with ISO 8528-12. 5.5.3 Automatic emergency lighting testing systems Automatic emergency lighting testing systems shall be designed, constructed and installed in accordance with the relevant requirements of national standards or national regulations. 5.6
Categories of operation
The mode of operation and duration shall comply with the results of the risk assessment in accordance with national regulations.

Servicing and testing
7.1
General
When automatic testing devices are used, the information shall be recorded monthly. For all other systems, the tests shall be carried out as described in 7.2 and the results recorded. Regular servicing is essential. The occupier/owner of the premises shall appoint a competent person to supervise servicing of the system. This person shall be given sufficient authority to ensure the carrying out of any work necessary to maintain the system in correct operation. 7.2
Routine inspections and tests
Where national regulations do not apply, the following shall be met. 7.2.1 General Because of the possibility of a failure of the normal lighting supply occurring shortly after a period of testing of the emergency lighting system or during the subsequent recharge period, all full duration tests shall wherever possible be undertaken preceding time of low risk to allow for battery recharge. Alternatively, suitable temporary arrangements shall be made until the batteries have been recharged. The following minimum inspections and tests shall be carried out at the intervals recommended in 7.2.2 to 7.2.4. The regulating authority may require specific tests.
EN 50172:2004
- 10 -
7.2.2 Daily Indicators of central power supply shall be visually inspected for correct operation. NOTE This is a visual inspection of indicators to identify that the system is in a ready condition and does not require a test of operation.
7.2.3 Monthly If automatic testing devices are used, the results of the short duration tests shall be recorded. Tests shall be carried out as follows: a)
Switch on in the emergency mode each luminaire and each internally illuminated exit sign from its battery by simulation of a failure of the supply to the normal lighting for a period sufficient to ensure that each lamp is illuminated. NOTE The period of simulated failure should be sufficient for the purpose of this clause whilst minimising damage to the system components e.g. lamps.
During this period, all luminaires and signs shall be checked to ensure that they are present, clean and functioning correctly. At the end of this test period, the supply to the normal lighting should be restored and any indicator lamp or device checked to ensure that it is showing that the normal supply has been restored. b)
In addition to a), for central battery systems, the correct operation of system monitors shall be checked.
c)
In addition to a), for generating sets, refer to the requirement of ISO 8528-12.
7.2.4 Annually If automatic testing devices are used, the results of the full rated duration test shall be recorded. For all other systems the monthly inspection shall be carried out and the following additional tests made: a)
each luminaire and internally illuminated sign shall be tested as per 7.2.3 but for its full rated duration in accordance with the manufacturer's information;
b)
the supply of the normal lighting shall be restored and any indicator lamp or device checked to ensure that it is showing that normal supply has been restored. The charging arrangements should be checked for proper functioning;
c)
the date of the test and its results shall be recorded in the system logbook;
d)
in addition, for generating sets, refer to the requirements of ISO 8528-12.
