Committees searching for “evacuation diagram requirements” usually land on material written against AS 3745, the Australian Standard. That is the right instinct and slightly the wrong search. In Queensland the obligation that actually binds a body corporate sits in the Building Fire Safety Regulation 2008, and the regulation does not use the word diagram. It says evacuation sign.
The distinction matters, because the regulation is what an inspector holds you to.
The 300 square metre threshold
Section 30(4) is the first thing to check, because it decides whether any of this applies to your scheme.
The evacuation sign obligation does not apply where the total floor area of the building is less than 300 square metres. Above that figure, it does.
For most schemes the answer is obvious. A single small block may fall under. A tower does not, and neither does a townhouse complex once the floor areas are added together. If your scheme sits anywhere near the line, have the area confirmed rather than assumed. The cost of guessing wrong is an obligation nobody has been meeting.
What the sign has to do
Section 29(1) defines an evacuation sign as one stating the procedures for safely evacuating the building in a fire or hazardous materials emergency. That is the whole test. It is a functional description rather than a design specification.
Section 30(3) then sets three placement conditions:
- displayed in a conspicuous position
- oriented so the direction shown corresponds with the actual direction of the route
- securely attached to a wall, or to the internal side of a door
The second condition fails most often. A diagram that is accurate but hung rotated ninety degrees from the corridor it describes is worse than no diagram at all, because someone will follow it under pressure.
Where AS 3745 fits
AS 3745 is the standard most evacuation diagrams are drawn to, and a diagram prepared to it will generally satisfy the regulation comfortably. It is not, however, the source of the Queensland obligation.
Two practical consequences follow. A supplier quoting “AS 3745 compliant” is describing the drawing, not confirming you have met section 30. And a scheme holding current diagrams but no written plan has solved the visible half of the problem and left the half an audit starts with.
The obligations attached to the sign
The sign is one item in a set, and committees routinely hold one without the others.
A written plan. Section 21(2) requires the fire and evacuation plan to be maintained in written form.
Annual review. Section 28(1) requires a review at intervals of not more than one year. That means the plan, not a glance at the diagram in the lift lobby.
Annual evacuation practice. Section 44(2) requires evacuation practice at intervals of not more than one year. Section 43(2) applies the same interval to budget accommodation buildings.
Records. Sections 45 and 46 require records of instruction given and of practices held, including dates and, for practices, the times the evacuation started and ended. Section 72(2) requires those records to be kept for at least two years.
That last one catches people out. The obligation is not only to do the thing. It is to be able to show you did it, two years later.
Who sits outside this
Section 20 excludes budget accommodation buildings that require a fire safety management plan under the Building Act or the Fire Services Act, and buildings used for residential services. Those buildings are not off the hook. They sit under a different and generally heavier regime.
What usually goes wrong in a scheme
Three patterns, in rough order of how often they turn up.
- Diagrams installed once and never revisited. A renovation moves a wall, a door is sealed, a new bin room appears. The diagram still shows the building as it was built.
- The plan and the diagram drift apart. A contractor replaces the signage, the written plan is not updated, and the two documents now describe different buildings.
- No records. The practice happened. Nobody wrote down the date or the start and finish times, so under section 72 there is nothing to show it happened.
Common questions
Is an evacuation diagram the same as an evacuation sign?
In ordinary use, yes. The Queensland regulation says evacuation sign, AS 3745 says evacuation diagram, and suppliers use both words. When a document quotes an obligation at you, check which instrument it is quoting.
Does a small townhouse complex need one?
It turns on total floor area, not building count. Under 300 square metres the section 30 obligation does not apply. Above it, it does.
How often do the diagrams have to be replaced?
The regulation sets an annual review interval for the plan at section 28(1). The practical trigger for redrawing a diagram is a change to the building, not a date on a calendar.
Who can prepare them?
The regulation does not reserve this work to a licensed class, the way pool safety certification is reserved. What matters is that the result satisfies sections 29 and 30 and matches a current written plan.
