Danger Signs: Complete Guide for Australian Workplaces hero image

Use Danger signs only for life‑threatening hazards. AS 1319 mandates a red DANGER oval on black with clear, specific hazard text.

Danger signs communicate the highest level of hazard in day‑to‑day workplace signage. They are used to warn of life‑threatening risks and must be unambiguous, highly visible and located where they will be seen before a person enters the danger zone.

This guide explains practical considerations for choosing, specifying, ordering and maintaining danger signs in Australian workplaces, with first‑hand notes on materials and manufacturing methods used by Sign Portal.

Purpose and legal context

Danger signs exist to alert people to hazards that could cause death or serious injury if not avoided. They are typically installed at entry points to hazardous areas or directly adjacent to the source of the hazard so the warning is seen in time to act.

In Australia, safety signage is guided by workplace health and safety laws and related standards. Organisations should confirm the exact requirements in their jurisdiction and any project specifications before ordering, especially for high‑risk industries such as construction, mining, energy and rail.

Standards and regulatory references (Australia)

Signage example

Because these signs target the highest hazard level, it’s important to use them only where warranted and to ensure they are not diluted by surrounding clutter or less critical messages.

Maintenance and inspection

Include signage in routine workplace inspections. Check for fading, abrasion, vandalism, peeling edges and loose fixings. Clean with mild detergent and water; avoid harsh solvents that may attack inks or plastics.

Replace signs that are illegible, damaged, incorrectly located due to layout changes, or no longer reflect the current site risk. For adhesive labels, inspect edges and re‑apply or replace if lifting is observed.

Repair

Where practical and permitted by your site standards, targeted repairs can extend service life between replacements. Always ensure any repair maintains legibility and hazard visibility consistent with AS 1319 and the original risk assessment.

  • Rigid panels (ACP/acrylic): Minor scratches can be de‑glossed and over‑laminated; impact‑dented ACP is best replaced if the face is creased or the core is exposed. If reflective faces are patched, use film of the same class (e.g., RA2 to RA2) and avoid seams through critical text.
  • Self‑adhesive labels: For edge lift, warm gently with a heat gun (low setting), press down with a felt squeegee, then apply edge sealant (e.g., 3M 3950) sparingly. If abrasion has removed ink, replace the label; do not hand‑touch‑up message areas.
  • Fasteners and fixings: Replace missing rivets/screws with like‑for‑like (prefer 316 stainless coastal). Add nylon or neoprene washers to reduce vibration wear. If holes are elongated, relocate the fixing or fit a backing plate.
  • Cleaning and graffiti: Use pH‑neutral detergent. For marker pen on laminated signs, try isopropyl alcohol first; avoid strong solvents that can haze acrylics or attack inks.
  • Documentation: Photograph before/after, update your sign register/QR, and record any wording or location changes so re‑orders match the as‑installed condition.

On request, we can supply a simple site repair kit (IPA wipes, felt squeegee, small RA1/RA2 patch pieces, edge sealant vials, VHB tabs, assorted stainless fixings) to support reactive maintenance between planned replacements.

Freight and delivery across Australia

Sign Portal ships Australia‑wide, including regional and remote locations. Rigid signs are packed flat with corner protection; vinyl labels ship on rolls. If your site has access constraints or special induction requirements, advise these at order so delivery can be planned accordingly.

How we help

As an Australian, Veteran‑Owned manufacturer with clean print rooms and a full suite of equipment, we produce consistent, durable danger signage at scale. Our in‑house capabilities mean accurate colour, sharp graphics and efficient repeat ordering for multi‑site customers.

Our installers and partners work to site requirements and carry appropriate inductions and tickets (e.g., Construction White Card; EWP WP where elevated access is required). We can pre‑label panels with location IDs/QRs and deliver kitted by area to speed installation during shutdowns.

If you need compliant rigid panels fast, order via Danger Signs (Rigid Panels) or speak with our team for project packs aligned to AS 1319 with sector‑specific references (e.g., AS 2865 for confined space entries, AS 2067 for HV).

Frequently Asked Questions

What defines a danger sign compared with other safety signs?

Use a danger sign when a hazard could cause death or serious injury. It should be highly visible, concise and placed so it is seen before entering the danger zone.

Do I need reflective material on danger signs?

Reflective is recommended for low‑light or night‑time visibility, or where vehicle lights will illuminate the sign. For well‑lit indoor areas, non‑reflective is usually sufficient.

Which material should I choose for outdoor danger signs?

For long‑term outdoor use, rigid panels like aluminium composite perform well. For temporary works, corflute is economical. Labels suit equipment and doors; add lamination for durability.

Can you print custom wording and symbols?

Yes. We produce custom messages, pictograms, QR codes and site codes. Provide vector artwork or request our team to set the layout to your specification.

How should danger signs be positioned on a site?

Place them at eye level on approach and near the hazard, avoiding visual clutter. Ensure adequate lighting and install at all likely entry points to the danger area.

What artwork files do you accept for danger signs?

Vector files (PDF, EPS, AI, SVG) are preferred. Outline fonts or include font files, and supply brand colours if exact matching is required.

How often should I replace danger signs?

Replace immediately if they are faded, damaged, obstructed, relocated due to layout changes, or no longer reflect the current risk. Include signs in routine inspections.

Do you ship to regional and remote locations?

Yes. We ship Australia‑wide, including regional and remote areas. Let us know site access or induction requirements when ordering.
