Introduction
Table 1 shows an overview of the different forms of emergency lighting. For more details see EN 1838.

Safety signs including adaptive safety signs
While EN 1838 includes luminous requirements for emergency escape lighting systems (and stand-by lighting
systems), this document provides electrical installation requirements specific for emergency escape lighting
systems together with verification, operation and maintenance documentation and test requirements for such
systems. Emergency lighting is a key element of building safety and of utmost importance to prevent harm
and save lives in emergency situations. Such situations are rare, but their rarity is also the reason why issues
may remain undetected and the functionality of the emergency lighting system may thus be impaired just in
the very moment that emergency lighting is actually required. Such issues may be related to building layout
updates or changes in use pattern, or simply the ageing of emergency lighting equipment over time, for
instance. Therefore, maintenance of emergency lighting systems is just as essential as its initial proper
installation.
Hence, this document does contain detailed requirements not only for the initial verification of emergency
escape lighting systems, but also for its continuous monitoring and maintenance which is the only way to
ensure that emergency escape lighting will adequately be provided whenever required.
Note that legal requirements throughout Europe are not limited to the initial installation of emergency lighting,
but also comprise requirements related to continuous monitoring and maintenance.
1 Scope
This document specifies electrical installation requirements specific for emergency escape lighting systems
together with verification, operation and maintenance documentation and test requirements for such systems.
NOTE 1 Emergency escape lighting includes escape route lighting, open area (anti-panic) lighting and high-risk task
area lighting. Escape route safety signs are part of emergency escape lighting.
NOTE 2 Emergency escape lighting systems include adaptive and non-adaptive systems, as well as high and low-
mounted systems.
This document does not cover stand-by lighting requirements.
NOTE 3 Systems used for stand-by lighting can also be used for emergency escape lighting, given the corresponding
requirements are fulfilled, see EN 1838.
