Changing from Exit to Pictograph.
Changing from Exit to Pictograph.
In Australia, the design, installation and operation of emergency lighting and emergency lighting systems have been covered by three standards.
Recently, new emergency lighting standards have been published to reflect international standards.
AS2293.1:2005 - Emergency escape lighting and exit signs for buildings - system design, installation and operation.
AS2293.3:2005 - Emergency escape lighting and exit signs for buildings - Emergency escape luminaries and exit signs.
Part 2 - AS/NZS2293.2:1995 - Emergency Evacuation Lighting for Buildings - Inspection and maintenance has not been updated.
Please Note: The new standard applies to Australia only, whereas the previous standard also applied to New Zealand.
The most significant changes made to the standard are:
REPLACEMENT OF THE WORD “EXIT” WITH A PICTOGRAM
The word “EXIT” on exit signs is replaced by a pictograph of a running man in one of three configurations:
Straight from Here
Left from Here
Right from Here
RESTRICTIONS ON USE OF ARROWS
The new standard eliminates the ability to use peel off arrow diffusers as the left and right versions do not use a central running man. Also, the new standard does not allow for the use of “arrow both ways”
REVISION OF VIEWING DISTANCES
The minimum height of the pictorial element for all illuminated exit signage is 100mm, with no limit on the maximum height.
The maximum viewing distance must be marked in the green background of each diffuser. The following different recommended pictorial element heights correspond to a maximum viewing distance:
WHEN TO USE PICTOGRAPH
The Australian Building Codes Board recognised the new Emergency Lighting standards from May 2006. Projects which have been approved after May 2006 must apply Pictograph exits.
Sites with pre-existing EXIT lighting installed may use either EXIT or Pictograph.
With the approval of local authorities, other options may be considered on a project by project basis.
