The number of evacuation diagrams required depends on the size, layout, and occupancy of the building. Under AS 3745-2010, evacuation diagrams must be displayed in prominent and strategic locations such as near exits, stairwells, lifts, corridors, and areas where occupants gather.
Each level of a building typically requires multiple diagrams to ensure they are clearly visible from any point of travel. A certified Fire Safety Advisor can determine the correct number and placement to ensure full compliance.
