Evacuation Diagrams: Signs and Symbols That Should Be Included

In all states of Australia, it is a requirement of AS 3745 2010 (‘Planning for Emergencies in Facilities’ Section 3.5) to have Evacuation Diagrams in all facilities, including common areas when referring to multi-tenanted buildings. Emergency Plan advises building owners and managers should make themselves aware of this legislation, especially the area of evacuation diagrams (evacuation signs) and the evacuation diagram symbols nominated to be used.

Building owners and managers should be aware that alterations to their building under a building approval more than likely will necessitate the evacuation diagrams requiring to be updated.

AS 3745-2010 specifies minimum size and content for evacuation diagrams, in particular, the figure below shows symbols used in evacuation Diagrams and Evacuation Signs.  Any alterations to evacuation diagram symbols must be in accordance with the symbols shown below.
