2016. It was prepared by Subcommittee CPL/34/9, Lampsand relatedequipment–
EL/1/1,Emergency lighting, under the authority of Technical Committee CPL/34,
LampsEL/1, Light and related quipmentlighting applications. A list of organizations
represented on these committees can be obtained on request to their secretary.

Supersessionw

This part of BS 5266 supersedes BS 5266-1:2005 and BS 5266-10:20082011, which
areis withdrawn.

Relationship with other publications

ie

This part of BS 5266 is intended for use in conjunction with BS EN 1838:1999(BS 5266-7:1999) 1) and BS EN 50172:2004 (BS 5266-8:2004).

prev

BS EN 50172:2004, 4.1 specifies compliance with the wiring rules given in HD
384/HD 60364. The UK applicable parts of HD 384/HD 60364 are implemented in
the IET Wiring Regulations (BS 7671).

The otherBS 5266 is published in the following parts of this standard are:
Part 1: Code of practice for the emergency lighting of premises;

Part 2: Code of practice for electrical low mounted way guidance systems foremergency use;

Part 4: Code of practice for design, installation, maintenance and use of optical fibresystems;

Part 5: Specification for components parts of optical fibre systems;

Part 6: Code of practice for non-electrical low mounted way guidance systems
for emergency use – Photoluminescent systems;

Part 7: Lighting applications – emergency lighting (also numbered BS EN 1838);

Part 8: Emergency escape lighting systems (also numbered BS EN 50172).

The following topics are covered in BS EN 50172 and BS EN 1838:

general requirements for emergency escape lighting;escape route lighting;open area (anti-panic) lighting;high risk task area lighting;standby lighting.

Detailed guidance on fire risk assessments is given in PAS 79, in a series of guides
published by the Department for Communities and Local Government [1–11], and inguidance published by the Justice Department of the Scottish Government [12–21].
Guidance on risk assessments for health and safety is given in HSE publication INDG
163 [22].
A summary of the hierarchy of standards covering the different aspects ofemergency lighting systems is given in Annex A.

BRITISH STANDARDInformation about this document
This is a full revision of the standard. It has been updated to assist those engineers
wishing to protect occupants from the hazards identified by risk assessments, andalso to evaluate existing premises to decide if they need to be upgraded to meetcurrent requirements. The standard has also been expanded to give guidance toprotect occupants from a sudden lossprincipal change introduced is an expansion of
the normalscope to cover emergency safety lighting supply.and standby lighting, as
well as emergency escape lighting.
The aim of this standard is to promote wider understanding of the different types of
emergency lighting system which may be employed, and to give guidance on theircorrect application to the varied requirements of different categories of premises.

wThe recommendations given in this standard have been drawn up to encourage
uniformity of application, based on providing adequate safety to people in the eventof interruption of the normal lighting, and having due regard to the hazard level anddegree of familiarity of occupants with particular premises.

previeThe standard recognizes that, in addition to ensuring safe unobstructed means ofescape from the premises at all times, an important function of emergency lighting is
to make possible the immediate location and operation of fire alarm call points andfire-fighting equipment, and another is to minimize the chance of panic arising inenclosed spaces, such as lifts. Although the standard makes recommendations for theprovision of emergency lighting in a wide variety of premises, the fact that particular
types of premises are mentioned in Clause 9 does not necessarily mean that all suchpremises will beare required by law to have emergency lighting installed. For certain
types of premises, the provisions of this standard might be supplemented or replacedby alternative requirements at the discretion of the enforcing authority.
