Sets out requirements for the design, installation and operation of electric emergency evacuation lighting systems for buildings, so as to provide visual conditions which will alleviate panic and permit safe evacuation of the building's occupants, should this be necessary, in the event of failure of the electrical supply to the normal lighting. Does not specify types of buildings nor particular locations which should be provided with emergency evacuation lighting.

This Standard specifies requirements for the equipment used and practices adopted in the provision of electric emergency evacuation lighting for buildings. Requirements for emergency luminaires and exit signs are specified by reference to AS/NZS 2293.3. The objective of the Standard is to provide visual conditions which will alleviate panic and permit safe evacuation of the building occupants, should this be necessary, in the event of failure of the electrical supply to the normal lighting.The Standard does not specify the types of buildings or the particular areas of buildings which should be provided with emergency evacuation lighting. This will normally be a matter for determination in accordance with the relevant building regulations. (See the Building Code of Australia or the New Zealand Building Code, as applicable.)There are some differences in the requirements specified for application in Australia and those for application in New Zealand. Such differences are identified at the appropriate place by a qualification such as 'In Australia' or 'In New Zealand', as applicable.NOTES:1 As it is never known when the emergency evacuation lighting may be called upon, it is essential that the system be regularly maintained. AS/NZS 2293.2 sets out inspection and maintenance procedures which are intended to ensure that the installation will continue to comply with this Standard.2 In Australia, requirements for the provision of emergency lighting in lift cars are given in AS 1735. In New Zealand, the comparable requirements are given in Approved Document D2 of the New Zealand Building Code.3 AS 3009 specifies requirements for the emergency standby lighting necessary in hospitals for continued patient care and requires that emergency evacuation lighting be provided in accordance with the requirements of this Standard and relevant building regulations.ApplicationThis Standard will be referenced in the Building Code of Australia by way of BCA Amendment 3 to be published by 1 July 1998, thereby superseding the previous referenced edition, AS 2293.1 -1987.This Standard may be called up by the Building Industry Authority in the Fire Safety sections of the Approved Documents which are expected to be re-published in 1999, thereby replacing AS/NZS 2293.1:1995 which is currently referenced by the New Zealand Building Code Handbook, Approved Document F6 as an Acceptable Solution to the New Zealand Building Code.
