Apply AS 1319 categories and colours/symbols to mark hazards, actions, exits and fire; size and place for visibility, then maintain and train.
If you are setting up safety signage for the first time, this guide will get you from “not sure where to start” to a practical plan. You will learn the basic categories of signs used across Australian workplaces, how colour and symbol conventions guide meaning, which materials suit different environments, how big signs should be, and where to place them. We also cover ordering, manufacturing and upkeep so your signs remain effective.
What safety signage means
Safety signage is a visual communication system that helps people identify hazards, know what actions are required, understand what is prohibited, and find emergency equipment and exits. Effective signs are visible, legible, consistent and placed where the message is needed most.
In Australia, workplaces commonly use a set of colour and symbol conventions to communicate meaning at a glance. These conventions support clear, consistent messages across sites and industries, from construction and warehouses to hospitals and schools.
Core categories used in workplaces

Most beginner programs start with five core categories. Knowing which category applies to a risk makes selection faster and keeps messages consistent across your site.
- Hazard/Warning: Alerts to a risk or dangerous condition so people can take care.
- Prohibition: States something you must not do (e.g., no access, no smoking).
- Mandatory: States an action you must do (e.g., wear eye protection).
- Emergency Information: Points to exits, first aid and emergency equipment.
- Fire: Identifies fire-fighting equipment and related locations.
Colour and shape conventions
Across Australian workplaces, common conventions help people recognise sign intent before reading text:
- Warning: Yellow background with black symbol or panel to signal caution.
- Prohibition: Red circle with a diagonal slash over a black symbol.
- Mandatory: Blue circle with a white symbol indicating a required action.
- Emergency information: Green background with white text/symbols.
- Fire: Red background with white text/symbols for fire equipment.
These conventions are widely used. Always confirm any project specification or regulator guidance that applies to your site before finalising artwork or purchasing.
Safety sign colours and symbols explained

In Australia, AS 1319 (Safety signs for the occupational environment) is the most-cited reference for workplace safety signs. It defines categories such as Danger, Warning, Mandatory, Prohibition, Emergency information and Fire. Many projects now also reference ISO 7010 symbol forms to support multilingual workforces. Where a principal contractor or client nominates ISO 7010 pictograms, we supply matching symbol artwork while maintaining Australian colour conventions.
- Danger signs: Used for life-threatening hazards. Typically feature a high-contrast DANGER header and clear message (e.g., High voltage, Confined space).
- Warning/Hazard signs: Indicate potential hazards that require caution (e.g., Forklifts operating, Wet floor). Yellow/black colourway aids quick recognition.
- Prohibition signs: Communicate an action that is not allowed (e.g., No entry, No smoking).
- Mandatory signs: Specify required actions (e.g., Hearing protection must be worn, Eye protection required).
- Emergency information signs: Identify first aid, emergency showers, eyewash, assembly points and egress routes.
- Fire signs: Identify equipment such as extinguishers, hose reels, fire blankets and valves. For location and selection of fire equipment, refer to AS 2444 in addition to site rules.
Emergency exit lighting and exit signs are governed by AS/NZS 2293. If your scope includes exits, ensure pictograms, illumination and placement comply with that series rather than general safety sign rules.
At Sign Portal, all symbols are maintained as vector masters with consistent stroke weights and clear-space rules. We size pictograms proportionally to the sign face so that symbol recognition is not compromised by long messages. Where a client provides legacy symbols, we will advise if the artwork is low contrast or out of date and supply updated alternatives for approval.
Materials and durability choices
Choosing the right substrate ensures your message stays readable for the life of the job. Consider environment (indoor/outdoor), permanence (temporary/permanent), impact risk, cleaning chemicals and UV exposure.
- Aluminium composite panel (ACP/ACM): Rigid, stable, excellent outdoors; suitable for long-term safety panels, site boards and fence signs.
- Acrylic (PMMA): Premium look for indoor safety and wayfinding; good clarity and stiffness; often paired with standoff mounts.
- Foam PVC (Foamex): Lightweight, cost-effective for indoor areas like amenities, offices and factories with low impact risk.
- Corflute (fluted polypropylene): Temporary, lightweight and economical for construction sites and short-term works.
- Polycarbonate: Very tough and impact-resistant; suited to harsh industrial zones and vandal-prone areas.
- Self-adhesive vinyl labels/decals: For equipment, doors, switchboards and curved surfaces; available with protective laminates.
In coastal or high-UV environments, prioritise substrates and inks that resist salt, heat and sunlight. Protective laminates or anti-graffiti films can add cleanability and abrasion resistance where needed.
Printing and manufacturing methods

How a sign is made affects durability, colour accuracy and lead times. At Sign Portal, safety signage is manufactured in-house using professional equipment and controlled production rooms.
- UV flatbed printing: Our two Mimaki JFX EX printers can direct-print full-colour graphics onto rigid substrates such as ACP, acrylic and foam PVC, producing durable, high-contrast safety messages.
- Wide-format print and cut: The Roland VG-640 prints vivid self-adhesive vinyl labels and decals, including contour-cut shapes for equipment and panels.
- Laser cutting and engraving: The Trotec Speedy 500 and a large-format 230 W CO2 laser handle acrylics and plastics for crisp symbols, tags and panels.
- CNC routing: Our MultiCam SM2412 profiles ACP and other rigid sheets to exact sizes and rounded corners where specified.
- Laminating: Clear overlaminates add abrasion resistance, UV protection and anti-graffiti properties to printed graphics.
This integrated workflow allows accurate colour matching, consistent symbol reproduction and fast repeat runs for multi-site programs.
Quality and compliance at Sign Portal
Production runs through documented checkpoints: artwork preflight and proofing, substrate verification, print profiling, finishing, and final QA. Our print rooms are colour-managed and we archive profiles with job numbers for repeatability across sites and reorders. For projects that reference AS 1319, AS/NZS 2293 or contractor-specific symbol libraries, our team cross-checks against the nominated specification during proofing and flags any conflicts early.
As a Veteran-Owned business with Local Buy credentials, we are familiar with government and enterprise procurement frameworks, including asset labelling, version control and audit trails. For long programs, we maintain customer-specific catalogues and lock approved artwork to reduce version drift.
Sizing and readability

Size signage so the key message and symbol are easily recognised from the typical viewing distance. Larger areas, open yards and vehicle routes call for bigger signs than small rooms or corridors.
- Use clear, simple wording with a prominent symbol.
- Maximise contrast between text/symbols and the background.
- Avoid clutter: one clear message per sign is usually most effective.
Before committing to a large order, test a print at intended size on-site to confirm legibility under real lighting.
Safety sign size and viewing distance calculator
Use this rule-of-thumb, derived from our in-house readability tests on typical Australian worksites. It provides a conservative minimum for body text and symbol visibility in normal lighting.
- Minimum x-height for text (mm) ≈ 3 × viewing distance (m) (e.g., 10 m → 30 mm letters)
- Minimum symbol diameter (mm) ≈ 5 × viewing distance (m) (e.g., 10 m → 50 mm pictogram)
Quick reference examples (pedestrian speeds, normal lighting):
- 2 m → 6 mm text, 10 mm symbol core → sign face ~150–200 mm wide
- 5 m → 15 mm text, 25 mm symbol core → sign face ~300–450 mm wide
- 10 m → 30 mm text, 50 mm symbol core → sign face ~450–600 mm wide
- 20 m → 60 mm text, 100 mm symbol core → sign face ~600–900 mm wide
- 40 m → 120 mm text, 200 mm symbol core → sign face ~900–1200 mm wide
Adjustments:
- Add 25–50% for low light, glare, or complex backgrounds.
- For vehicle routes or high approach speeds, size up one category.
- Prioritise the signal word and symbol; secondary detail can be smaller.

Placement fundamentals
Place signs where decisions are made: at entrances to hazardous areas, on or near equipment, along access routes and at exits. Keep them at a consistent height and angle to face approaching traffic or pedestrians.
- Mount to stable, clean surfaces using appropriate fixings or adhesives.
- Avoid obstructions by doors, stacks, or vegetation.
- Group related messages logically (e.g., PPE requirements together).
Temporary versus permanent
Match permanence to the risk duration. Temporary solutions suit short works; permanent solutions suit ongoing controls and essential equipment locations.
| Feature | Temporary | Permanent |
|---|---|---|
| Typical materials | Corflute, removable vinyl, site boards | ACP, acrylic, polycarbonate, fixed vinyl panels |
| Use case | Construction stages, short shutdowns, events | Fixed hazards, plant rooms, emergency and fire |
| Fixing method | Cable ties, temporary adhesives, stands | Screws, rivets, VHB tapes, permanent adhesives |
| Durability | Weeks to months, weather permitting | Years with suitable substrate and print system |
| Cost focus | Economy and speed | Longevity and lifecycle value |
Reflective and photoluminescent options
For low-light or night-time visibility, specify reflective films. Where a road authority or project standard applies, nominate the required performance class (e.g., engineering-grade or high-intensity microprismatic to AS/NZS 1906.1). For egress systems, photoluminescent and emergency exit signage must meet AS/NZS 2293 requirements set out for your building type and lighting conditions.
Artwork and file preparation
Clear artwork speeds production and reduces errors. Supply vector artwork for symbols and text where possible.
- Provide logos and icons as vector files (AI, EPS, PDF) and outline fonts.
- Keep backgrounds clean; prioritise contrast for legibility.
- Allow safe margins around symbols and text; avoid placing content too close to edges.
- If you need help, request standard symbol sets for faster approval.
Ordering checklist
When requesting a quote or placing an order, include the following so our team can manufacture accurately and quickly:
- Sign category and message intent (e.g., mandatory eye protection).
- Quantity, sizes and orientation.
- Material (e.g., ACP 3 mm, foam PVC), finish (matte/gloss), and any laminate (anti-graffiti, UV).
- Fixing method (holes, rounded corners, tapes, stand-offs) and placement notes.
- Indoor/outdoor use, exposure (UV, coastal, heat), and required lifespan.
- Any reflective requirement for night visibility.
- Delivery address, access notes and required date; we ship Australia-wide including regional and remote areas.
How Sign Portal manufactures and delivers
Safety signs are produced in our approximately 480 m² facility with clean, specialised print rooms for consistent colour and quality. We use direct UV flatbed printing on rigid substrates, wide-format print-and-cut for labels, CNC routing for shaped panels and laser systems for plastics work.
Quality control checks verify artwork, colour, dimensions and finishing before packing. Orders are consolidated and shipped Australia-wide, with protective packaging suited to the materials and route. As a Veteran-Owned business with Local Buy credentials, we support government and enterprise procurement requirements.
For repeat programs, our Trade Portal and customer-specific catalogues streamline reordering and ensure version control across multi-site networks.
Maintenance and inspection
Safety signage must remain readable and secure. Build a light-touch inspection routine into your site checks.
- Clean with mild detergent and soft cloths; avoid harsh solvents unless the material and laminate are rated for them.
- Inspect for fading, abrasion, peeling edges and missing fixings.
- Replace damaged or illegible signs promptly; do not defer if meaning is compromised.
Repair and refurbishment
Not every issue requires a full replacement. For common damage modes, the following repair approaches can restore function quickly while you plan permanent changes:
- Graffiti and surface marks: If laminated with an anti-graffiti film, remove with approved cleaners per the laminate’s data sheet. For unlaminated prints, use mild isopropyl alcohol first; avoid strong solvents that can attack UV inks or plastics.
- Lifted corners or edges (vinyl panels/decals): Clean and dry the substrate, warm gently to reactivate adhesive, trim any distorted section and apply a pre-cut overlay patch. Use a surface primer (e.g., VHB primer) before re-bonding in high-wear areas.
- Cracked or bent panels (ACP/polycarbonate): If the message is compromised, replace the panel. Minor edge dings on ACP can be deburred and resealed to prevent moisture ingress until replacement arrives.
- Faded symbols/messages: Apply a purpose-printed overlay to restore contrast. This is effective for critical messages where the base panel and fixings are sound.
- Loose fixings: Replace with corrosion-resistant hardware matched to the environment (e.g., 316 stainless near coastal areas). Where adhesives are used, remove old foam tape completely and re-fit with fresh VHB tape after cleaning with isopropyl alcohol.
Sign Portal can supply field repair kits for common formats: pre-cut overlays, cleaning wipes compatible with our laminates, edge sealers for ACP, fixing packs, and surface primers. Speak with our team to match a kit to your materials and site conditions.
Common mistakes to avoid
A few preventable errors reduce effectiveness and drive up long-term cost:
- Using too many messages in one place, creating visual noise.
- Choosing indoor materials for outdoor, high-UV or coastal exposure.
- Undersizing text and symbols for the viewing distance.
- Inconsistent terminology between signs and procedures.
Australian environment considerations
Australia’s conditions can be harsh on signage. Plan materials and finishes with environment in mind:
- High UV: Prefer UV-stable inks and protective laminates; select rigid substrates that resist warping.
- Coastal salt: Use corrosion-resistant fixings and stable substrates; seal edges where appropriate.
- Heat and dust: Tougher substrates and laminates help with cleaning and abrasion.
- Mining and heavy plant: Impact-resistant options like polycarbonate or thicker ACP improve longevity.
- Warehouse PPE boards printed on ACP with rounded corners and pre-drilled holes for masonry fixing.
- Construction hazard panels on corflute cable-tied to temporary fencing during short works.
- Machine safety labels produced as laminated vinyl decals for curved guards and housings.
When to replace
Replace a sign if it is faded, cracked, obstructed, missing, or no longer reflects the current hazard or procedure. After equipment changes or task redesigns, review affected signage during handover.
Getting started
Walk your site with a simple checklist: identify hazards and controls, map where decisions happen, match each location to a sign category, select materials to suit exposure, confirm sizes and fixings, then request a consolidated quote.
