Evacuation diagram builder
Most sites have an emergency sign with names and numbers on it. Far fewer have the other thing —
a diagram showing where you are, where the exits are and where everyone goes. This builds one.
Drop the markers on your plan, and the legend writes itself.
Your site plan never leaves this device. The image is read by your browser and drawn on screen —
it is not sent to us or stored anywhere. Close the tab and it is gone, so print or save the PDF before you do.
What an evacuation diagram is expected to show
The Australian reference for emergency planning in facilities is AS 3745, and most
principal contractors will expect a site diagram to follow the same shape. This is the list of
elements it is normally expected to carry. It is a checklist, not a legal opinion.
- A pictorial representation of the area — a plan, not a description.
- “YOU ARE HERE” — and the diagram oriented the way the reader is facing when they look at it. A diagram rotated the wrong way is worse than none.
- Designated exits, marked clearly. Green is the convention.
- The assembly area, on the diagram and written out in words.
- Firefighting equipment where it is provided — extinguishers, hose reels, blankets.
- Communications equipment where provided — alarm points, warden phone.
- A legend that covers every symbol actually used, and nothing that is not.
- The date it was prepared or last validated.
- Orientation — a north point, or clear alignment with the building.
Getting it right on a construction site
- It changes as the job changes. A diagram drawn at slab stage is wrong by lock-up. Re-date it every time the exits or the compound move.
- Put it where people actually stand — the shed, the gate, the lift lobby, the crib room. One in the site office helps nobody at 3pm on level 8.
- The assembly point must work in the dark and in the rain, and be clear of the building and of emergency vehicle access.
- Walk it before you print it. If the drawn route runs through a locked gate or a live work zone, you have documented a hazard rather than a plan.
- Print it big enough to read. A4 for a small area, A3 for anything complex.
- A diagram is not a drill. Running the evacuation and recording who attended is the part that gets tested after an incident.
What this tool is. It produces a clear, printable diagram from what you enter. It cannot see your site,
so it cannot tell you whether the exits, routes or assembly point are adequate. That assessment has to be made
by the competent person responsible for emergency planning on the job, and the diagram checked against the
actual site before it goes on the wall.
The rest of the emergency paperwork
The diagram is one part. The emergency plan, the warden roles, the drill
record and the incident report are the rest — and they are the ones an inspector asks for.
This is a practical site-management tool. It is not legal, engineering or regulatory advice and does not guarantee compliance or a satisfactory inspection outcome. Requirements may vary by jurisdiction, project, contract and circumstances.
