Use one message, plain specific verbs, state who/where, add a pictogram, and test readability on site before approval.
Clear wording on a safety sign helps people recognise a hazard or required action in seconds. This guide shows a simple, repeatable way to write short, specific and scannable text for custom safety signs used on Australian worksites, facilities and public spaces.
Quick checklist
When writing a safety sign, keep to one message, use plain language, state the required action and make it scannable. Draft your text, test it at the intended viewing distance and get a local safety lead to approve before ordering.
- One message per sign (hazard, prohibition, mandatory action or information).
- Use familiar headings if your site has a convention (e.g. Danger, Warning, Caution, Notice).
- Say what to do, who must do it and when/where it applies.
- Prefer short, concrete verbs: Keep, Wear, Isolate, Do not enter.
- Support with a pictogram where helpful; avoid duplicates or contradictions.
- Proofread, run a quick readability test on-site, and record the approved wording for reorders.
Download the printable Safety Sign Wording Checklist (A4 PDF) – includes a sign-off box for approvals, a field for location/asset ID, and a line-height guide you can hold up on site.
- Message type tick-box (Hazard / Prohibition / Mandatory / Information) per AS 1319 conventions.
- Wording fields: What (action), Who (audience), Where/When (scope), Why (optional short reason).
- Layout prompts: heading, line breaks, pictogram choice, arrow orientation, contrast check.
- Readability aide: letter-height ruler (mm) and a distance field for your walk-back test.
- Approvals: preparer, safety lead, date, revision, site/location code, asset ID/QR.

Decide the core message
Start by deciding the single most important outcome: prevent a specific harm, keep people out, or ensure a protective action. Trying to say everything on one sign makes people read nothing.
- Hazard: what could cause harm? (e.g. High voltage, Forklifts operating)
- Action: what must people do or avoid? (e.g. Wear eye protection, Do not enter)
- Audience: who must act? (e.g. Contractors, Visitors, Staff only)
- Scope: where and when? (e.g. During loading, Beyond this point, In test area)
Choose the heading and tone
Many Australian workplaces use consistent colour and heading conventions across their sites (for example, a bold hazard heading for serious risk, or a neutral information heading for general notices). Match your wording tone to the level of risk and your site's established conventions so staff and visitors recognise the type of message on sight.
Avoid softening critical instructions. Say "Do not operate without guard" rather than "Please avoid operating without guard". For informative notices, keep a neutral tone and skip unnecessary formality.
Keep language simple and specific
Write like a spoken instruction. Prefer short words, present tense and direct verbs. Name the thing, the action and the condition in 10–12 words or fewer where possible.
- Specific: "Wear hearing protection past this point"
- Not vague: "Hearing PPE recommended here"
- Specific: "Authorised staff only beyond this door"
- Not vague: "Restricted area please"
Examples: unclear vs clear
Use the examples below to tighten wording. Each improvement removes ambiguity, adds a direct verb and specifies who/where/when.
| Feature | Option A | Option B |
|---|---|---|
| Access control | Restricted area | Authorised personnel only beyond this point |
| Prohibition | No entry | Do not enter – live testing in progress |
| Mandatory PPE | Use PPE | Wear safety glasses and hearing protection |
| Hazard alert | High noise area | High noise – hearing protection required past this line |
| Process safety | Isolate before work | Isolate and lock out power before maintenance |
| Traffic management | Beware forklifts | Forklifts operating – keep to pedestrian walkway |
| Hygiene | Wash hands | Wash and dry hands before returning to work |
| Chemical area | Eye wash here | Emergency eyewash – flush eyes for 15 minutes |

Make it scannable
People should understand the sign in a quick glance. Use a short heading, a single instruction line and an optional secondary line only if it adds essential clarity.
- Break long instructions into two short lines rather than one dense line.
- Keep punctuation minimal; a dash can separate the condition (e.g. "Do not enter – roof work above").
- Use consistent casing across your site. Avoid ALL CAPS for long sentences as it reduces legibility.
Include only essential details
Every extra word slows recognition. If it is not critical to the action, leave it out. Use a pictogram to reinforce the instruction instead of adding more text.
- What: the action or prohibition (Do not enter, Wear gloves).
- Who: the audience if restricted (Visitors report to reception, Contractors only).
- Where/when: the boundary or condition (Beyond this door, During loading).
- How: only if it prevents a common error (Isolate and lock out power before maintenance).
Plan for distance and readability
Wording must be legible where people first need to act, not just up close. If you are unsure about letter size, do a quick on-site test: print your wording at the planned text height, stick it up and walk the approach path. If you cannot read it comfortably before the decision point, enlarge the text or move the sign.
Place the sign in an unobstructed line of sight, avoiding visual clutter. Repeat the message at secondary entry points if people can approach from multiple directions.

Case study: site entry board — before and after
A Tier-2 builder asked Sign Portal to tighten the wording on a crowded site entry board that was being ignored at peak times. The board mixed access rules, PPE, traffic and visitor instructions in one block of text.
| Section | Before (ineffective) | After (Sign Portal revision) |
|---|---|---|
| Visitors | All visitors must report to office | Visitors: Report to Site Office → |
| Access | Restricted area / Staff only | Authorised personnel only beyond this point |
| PPE | PPE required | Wear hi-vis vest and safety boots past this point |
| Traffic | Drive slowly / No parking | Speed limit 10 km/h • No parking at gate |
| Deliveries | Use correct gate | Deliveries: Use Gate 2 off Smith St |
| Works in progress | Keep clear | Do not enter – crane lift in progress |
- Clear sections with bold headings reduced queueing at the intercom during morning peak (reported by gatehouse).
- Supervisors observed faster PPE compliance at the boundary and fewer wrong-gate deliveries in the first month.
- The approved wording set is now saved to the client's account for consistent replacements across new projects.
- Content audit on-site with the site manager to separate access, PPE, traffic and visitor flows into distinct panels.
- Wording workshop: replaced abstract nouns with direct verbs; added short reasons only where behaviour depended on context (e.g. “– crane lift”).
- Prototype test: printed two 600 mm mock-ups at final letter height, placed at the gate for a morning peak walk-through with the gatehouse.
- Final artwork locked to the client’s template and saved against their account for repeat use on future sites.
Use pictograms and arrows wisely
Pictograms help people understand faster, including those with limited English. Choose a symbol that clearly supports the instruction and keep it consistent across your site. Use arrows to indicate direction only when the message changes with direction (e.g. "Assembly point →").
Avoid stacking multiple symbols that compete with each other. If you need several related instructions in one place (e.g. PPE set), group them into a neat grid rather than scattering icons around text.
Templates you can adapt quickly
Use these starter patterns and replace the bracketed parts with your details. Keep them short and check for site consistency.
- Access control: "Authorised [role] only beyond this point"
- Live work: "Do not enter – [task] in progress"
- Mandatory PPE: "Wear [PPE item] in this area"
- Prohibition: "Do not [prohibited action]"
- Process safety: "Isolate and lock out [system] before maintenance"
- Traffic: "Forklifts operating – keep to pedestrian walkway"
- Hygiene: "Wash and dry hands before returning to work"
- Emergency: "Emergency exit – keep clear"
- Construction gate: "Visitors report to site office" at eye height on the pedestrian entry.
- Food prep area: "Wear hair net beyond this point" at the gowning station.
- Switch room: "Authorised electricians only – live panels" on the door and inside near boards.
- Warehouse aisle: "Forklifts operating – use pedestrian walkway" at each aisle end.
Common pitfalls to avoid
- Two commands in one line (e.g. "Wear PPE and do not enter without permit"). Split into two signs or two lines with clear separation.
- Vague verbs ("Be careful"). Replace with a specific action ("Keep off platform").
- Hidden conditions ("No entry" without why). A short reason improves compliance ("– confined space").
- Inconsistent wording across sites ("PPE required" vs "Wear PPE"). Pick one style and stick with it.
- Text too small for the approach speed or distance. Do a walk-back test before ordering multiples.
Approvals and version control
Agree on the wording with your safety representative or site manager before production. Record the approved text in a shared document with location, date and sign size so the same wording is used on future replacements.
When you order, include the exact text (with line breaks), any required pictograms and a quick sketch of layout. This prevents rework and speeds production.
For traceability, ask us to print a discreet asset ID/QR on the back or border (location code + revision, e.g. "GATE-A/REV-C"). This helps with audits, reorders and scheduled replacements.
From wording to finished sign
Once your text is approved, production is straightforward. At Sign Portal, safety sign panels are typically direct-printed using UV flatbed technology on durable sheet materials, then cut to size and finished for installation.
- Printing: Direct UV printing on our Mimaki JFX EX flatbed printers produces crisp text and symbols with strong colour. We print on aluminium composite (ACM), Colorbond steel, polypropylene and other common safety substrates. White ink is available where needed.
- Cutting: Panels can be precision-cut on the MultiCam SM2412 CNC router or Trotec Speedy 500 laser depending on material.
- Labels and decals: Self-adhesive safety labels can be wide-format printed and contour-cut on the Roland VG-640.
- Finishing: Options include pre-drilled holes, rounded corners, anti-graffiti laminate and edge de-burring for safe handling.
- Reflective: Where visibility at night is required, specify reflective media (e.g. engineer-grade or higher). We size wording to maintain contrast and legibility.
- Quality checks: We verify text content against your approved proof, spot-check colour/contrast, and conduct adhesion tests on new material batches before release.
Clear, concise wording pairs well with high-contrast print and the right material for your environment. If you are unsure, describe where the sign will be installed when you order so we can help match material and finish to conditions. Where applicable, we follow the layout principles of AS 1319 (Safety signs for the occupational environment); confirm any site-specific requirements with your WHS advisor.

Manufacturing quality and compliance at Sign Portal
- Colour management: Device profiles are maintained with in-house spectro checks; we run control strips and visual contrast checks to keep symbol and text legible on high-visibility backgrounds.
- Fine text settings: Small copy is printed at higher-pass modes with optimised UV curing to avoid dot gain in the bowls of letters like e, a and o.
- Material pairing: ACM and Colorbond are specified for outdoor longevity; polypropylene for wet-process areas; reflective films selected to suit the ambient lighting and approach speed (consider AS/NZS 1906.1 classes when required by your traffic plan).
- Durability tests: New substrate/ink stacks receive an adhesion cross-hatch and tape test on receipt; we also conduct wipe tests with pH-neutral cleaner to validate anti-graffiti compatibility.
- Traceability: Each job can carry a discreet backstamp with job number, material batch and revision so inspections and reorders are frictionless.
Ordering tips that save time
Provide wording exactly as it should appear, including intended line breaks and any arrows or symbols. Note the sign location so we can centre or align text appropriately (e.g. align with a left boundary line or a door edge).
- Include: final wording, symbol list, layout notes, quantity, size, material preference and fixing method.
- Attach: a photo of the install location for context if available.
- Reorder easily: keep your approved wording on file; Trade customers can use repeat-order tools to minimise data entry and maintain consistency across sites.
- Optional: request an asset ID/QR code on the reverse or border to streamline future inspections and replacements.
Sign lifecycle: deliver, install, inspect, maintain, repair, replace
Great wording is only effective if the sign reaches site intact, is installed correctly, and remains legible over time. Build these steps into your safety sign program.
Deliver
- Packaging: Panels are corner-protected and face-wrapped; labels show job number, location and panel count per bundle.
- Transport notes: Tell us if a forklift, tail lift or hand unload is required. Remote/regional deliveries may be palletised.
- On receipt: Inspect for transit damage before signing; photograph any issues and note on the consignment docket.
Install
- Fixings: Use stainless steel (preferably 316) screws/bolts for outdoors. For masonry, use wall plugs or anchors sized to wind load.
- Adhesive mounting: Where drilling is not suitable, use high-bond acrylic foam tape on clean, dry, degreased surfaces. Roll with firm pressure; allow dwell time as per tape data sheet.
- Positioning: Mount at typical eye height (1.5–1.7 m to baseline) and square to approach. Avoid glare and obstructions.
- Structural: On fences or mesh, use saddles/cable ties rated for UV; add backing board if the substrate flexes.
Inspect
- Set a schedule: High-traffic/outdoor locations – quarterly; low-risk indoors – every 6–12 months.
- Checkpoints: Visibility (blocked view), legibility (fading, peeling), relevance (process change), fixing integrity and vandalism/graffiti.
- Record: Note asset ID, condition and actions taken. Scan the QR (if fitted) to log your inspection.
Maintain
- Cleaning: Use pH-neutral detergent and water with a soft cloth. Avoid abrasive pads and strong solvents on printed faces.
- Anti-graffiti: If specified, remove graffiti with compatible cleaner; test a corner first.
- Environment: Trim back vegetation and remove temporary obstructions that reduce sightlines.
Repair
- Minor damage: Replace individual fixings, re-level, or apply a new adhesive set if a corner lifts.
- Content updates: For small changes (e.g. updated speed limit), consider a precisely sized overlay label as a temporary measure until a full replacement is produced.
Replace
- End of life: UV exposure, abrasion or chemical washdowns eventually reduce contrast. Typical outdoor service life varies by exposure; plan proactive replacement in high-UV or corrosive areas.
- Trigger events: Incident findings, process changes, plant moves or updated legislation/standards.
- Fast reorder: Quote the asset ID/old job number; we keep your approved artwork and wording for like-for-like replacements.
- Food plant: Monthly wipe-down of PPE boards; annual audit of wording against HACCP updates.
- Warehouse yard: Quarterly inspection of traffic signs; replace faded "5 km/h" plates on the sunniest fence line first.
- Workshop: Add "Do not enter – live testing" swing tags when benches are energised; retire tags with illegible print.

Frequently Asked Questions
How many words should a safety sign have?
Aim for one short heading and a single instruction line. If you cannot say it in 10–12 words, split it into two lines or two signs.
Should I include the reason, like 'because it's dangerous'?
Add a short reason only when it improves compliance or clarity, e.g. "Do not enter – live testing in progress". Avoid long explanations.
Do I need a pictogram as well as text?
Pictograms help scanning and assist non-native readers. Use one clear symbol that supports the instruction rather than several competing icons.
How can I check if the text size is readable?
Print the wording at the planned letter height, place it on-site and do a walk-back test from the approach path. If you struggle to read it, increase size or improve placement.
Can I put multiple rules on one sign?
Only if they are tightly related and scannable as separate lines or icons. Otherwise, use separate signs or a board with clear sections.
What file should I send for my custom wording?
A simple text email with exact line breaks is fine. If you have artwork, supply a vector PDF or EPS and list any required symbols.
Will my wording be edited by Sign Portal?
We can flag obvious clarity issues on request, but final wording is your responsibility. Provide an approved version to avoid delays.
