What Safety Signs Does a Construction Site Need? (Australian Guide)
Setting up a new building site, renovation or fit-out? The right signs tell workers, visitors and the public about hazards, what protective equipment is required, and where to go in an emergency. This guide covers the safety signs most Australian construction sites use, where to put them, and how to choose materials that last for the life of the project.

The essential signs for most construction sites
Every site is different, and the signs you need should come from your own risk assessment. That said, most sites start with the same core set:
- Site entry danger sign – a Danger – Construction Site, Authorised Personnel Only sign at each gate and along fencing facing public areas warns people that the site is hazardous and not open to the public.
- Mandatory PPE signs – blue mandatory signs at the entry for safety helmets, safety footwear and high visibility clothing make the site's PPE rules clear before anyone walks in.
- First aid sign – a First Aid Station sign shows where the first aid kit or station is.
- Fire equipment sign – a Fire Extinguisher sign above or beside each extinguisher helps people find it quickly.
- Emergency assembly sign – an Emergency Assembly Area sign marks where everyone gathers after an evacuation.
- Site contact sign – a sign with the builder or principal contractor's name and contact details (see below).
As work progresses you may also need task-specific signs – for example warning signs for vehicles and forklifts, or danger signs for excavations, overhead work and electrical hazards.
Principal contractor and site contact signs
Under the model Work Health and Safety Regulations (regulation 308), the principal contractor for a construction project must ensure signs are installed that show the principal contractor's name and telephone contact numbers – including an after-hours number – and the location of the site office, if there is one. The signs must be clearly visible from outside the workplace, or the work area where the construction project is being carried out.
The model regulations have been adopted with variations by most states and territories. Victoria has its own OHS laws, and the thresholds and details differ between jurisdictions – check the requirements for your project with your regulator, such as Safe Work Australia, WorkSafe Victoria or SafeWork NSW.
Where to put each sign
- Every entry point: the danger sign and the PPE signs, at eye level and facing people as they arrive.
- Fence lines next to footpaths, roads and neighbours: additional danger signs so they're visible from every side of the site.
- First aid and fire equipment: directly above or next to the equipment, so the sign stays useful if the equipment is moved.
- Assembly area: at the agreed evacuation point, somewhere safe and away from vehicle movements, visible as people approach.
Check signs regularly. Fencing mesh, stacked materials and parked vehicles often end up hiding signs, and signs should change as the site changes.
Choosing the right material
- Corflute – lightweight, weatherproof and economical. The usual choice for temporary fencing and short-to-medium projects.
- PVC Foam Board – smooth and rigid. Good for site offices, sheds, amenities and sheltered spots.
- Colorbond – rigid pre-painted steel for long-running projects, or signs you want to reuse on the next job.
For size, choose larger signs where they need to be read from further away – for example on a site boundary facing a road.
The easy option: a complete site kit
Our Construction Site Safety Sign Kit includes all seven signs listed above (the site entry danger sign, three PPE signs, first aid, fire extinguisher and emergency assembly area), in Corflute, PVC Foam Board or Colorbond, standard or large. It costs less than buying the signs separately, and it comes with a free printable site safety document pack: a sign placement checklist, site inspection checklist, visitor sign-in register, induction checklist, toolbox talk record, emergency contacts poster and hazard and incident report form.
Frequently asked questions
Does every construction site need the same signs?
No. The signs you need depend on the hazards on your site, which should be identified through your risk assessment. The signs in this guide are a common starting point for most building sites.
Is a principal contractor sign required on every job?
The regulation 308 duty applies to principal contractors for "construction projects" as defined in the WHS regulations, which depend on the value of the work, and the rules vary between states and territories. Check with your regulator for your project.
Which material is best for a construction site?
Corflute is the most common choice for temporary site fencing because it's light and economical. Choose Colorbond for long projects or signs you want to reuse.
Do safety signs make my site compliant?
Signs are one part of managing safety on site. They don't replace risk assessments, safe work method statements, induction, supervision or other controls required under WHS or OHS laws.
