What Does a WHS Prohibition Notice for Non‑Compliant Hi‑Vis Look Like?
The morning shift on a Melbourne construction site was about to start when a supervisor spotted a worker’s high‑visibility vest that had faded to a dull orange. Within seconds the site’s WHS officer hand‑held a prohibition notice and ordered the crew to stop work until every vest met the required standard. The delay cost the project hours, and the crew faced a potential fine from SafeWork NSW. That paperwork isn’t just a formality – it’s a clear signal that a non‑compliant hi‑vis garment is a safety breach, not a fashion choice. Below, we break down exactly what a WHS prohibition notice for hi‑vis looks like, why it matters, and how to keep your site clear of it.
The Anatomy of a WHS Prohibition Notice
A prohibition notice is a short, formal document issued under the Work Health and Safety Act. When it targets hi‑vis clothing, you’ll see these key elements:
| Element | What it says | Real‑world meaning |
|---|---|---|
| Header | “Work Health and Safety Prohibition Notice” – issued by SafeWork NSW / WorkSafe Victoria / WHS Queensland | The authority is backing the stop‑work order. |
| Reference | “Reference: WHS‑2026‑00123 – Non‑compliant high‑visibility safety vest” | Specific to the vest issue, not a general site breach. |
| Risk description | “The vest worn by employee # 23 does not meet AS/NZS 4602.1:2006 Class D/N requirements – reflective tape width is 35 mm and colour is faded.” | Pinpoints exactly why the vest fails – tape too narrow, colour faded. |
| Required action | “All workers must wear compliant hi‑vis garments that meet AS/NZS 4602.1, AS/NZS 1906.4, and AS 1742.3 standards. Replace non‑compliant items within 24 hours.” | Clear instruction: replace or upgrade the vest immediately. |
| Compliance deadline | “Work may resume no earlier than 09:00 A.M. on 03 May 2026, provided corrective action is demonstrated.” | Gives a concrete time‑frame; nothing can happen until it’s met. |
| Signature | WHS Officer’s name, badge number, and contact details | You can follow‑up if you need clarification. |
The notice will usually be printed on official WHS letterhead, stamped, and delivered to the site manager or the person in charge of personal protective equipment (PPE). It’s not a “nice‑to‑have” reminder – it’s a legal stop‑work direction.
Why the Details Matter: Compliance Breakdown
| Requirement | Standard | What it means on site |
|---|---|---|
| Class D (Day) | AS/NZS 4602.1 | Fluorescent yellow‑green or orange‑red with at least 50 mm of reflective tape encircling the torso – for daytime work. |
| Class N (Night) | AS/NZS 4602.1 | Same colours plus additional reflective tape on sleeves, shoulders, and rear – for low‑light conditions. |
| Class D/N (Day/Night) | AS/NZS 4602.1 | Meets both day and night criteria – the most common class for construction sites. |
| Class R (Roadwork) | AS/NZS 4602.1 | Fluorescent orange‑red with reflective tape on front and back, plus rear‑facing reflective panels for traffic control. |
| Reflective tape | AS/NZS 1906.4 | Minimum 50 mm width, 100 % retro‑reflective, fully encircling torso. |
| Colour standards | AS 1742.3 | Only fluorescent yellow‑green or orange‑red are approved for hi‑vis PPE. |
If any of these boxes are unchecked, a WHS officer can issue a prohibition notice on the spot.
Practical Tool: Hi‑Vis Compliance Checklist
Print this checklist, hang it in the PPE store, and run it before any shift starts.
- Identify the class required – D, N, D/N, or R.
- Check colour – fluorescent yellow‑green or orange‑red only.
- Measure reflective tape – at least 50 mm, fully encircling torso.
- Inspect tape condition – no peeling, fading, or damage.
- Verify night‑time requirements – sleeves and shoulders reflective for Class N/D‑N.
- Confirm branding placement – logos must not cover more than 5 % of the reflective surface.
- Record the vest’s tag number – cross‑check against the site’s PPE inventory list.
If any item fails, replace the vest before the worker steps onto the site.
Where Sites Go Wrong
- Wrong vest class – Using a Class D vest on a night‑shift roadwork crew flags an immediate breach.
- Faded hi‑vis – Sun‑bleached or washed‑out garments lose the required fluorescence, and reflective tape can lose its retro‑reflectivity.
- Cheap non‑compliant imports – Some overseas suppliers market “high‑visibility” gear that doesn’t meet AS/NZS 4602.1 or AS/NZS 1906.4.
- Incorrect branding placement – Oversized logos that cover reflective tape compromise visibility and trigger a notice.
These errors are often spotted during routine WHS audits, leading to the dreaded prohibition notice.
Industry Examples
Construction – Melbourne CBD High‑Rise Build
A foreman ordered his crew to wear “bright orange” vests bought from a discount retailer. The reflective tape was only 30 mm wide, and the colour had faded after two weeks of rain. SafeWork NSW issued a prohibition notice, halting all work for 48 hours while the crew sourced compliant vests from a local supplier.
Traffic Control – Brisbane Road Upgrade
During a night shift, traffic controllers wore Class D vests without the required night‑time reflective sleeves. WorkSafe Victoria stopped the work and demanded Class R (roadwork) vests with full rear‑facing reflectors before traffic could be re‑opened.
Warehousing – Perth Distribution Centre
A new batch of “custom‑printed” hi‑vis shirts arrived with the company logo printed over the reflective strip on the back. The WHS officer cited the site for a breach of AS 1742.3 because the branding reduced the reflective area. The site had to reorder the shirts with the logo placed on the chest only.
Frequently Asked Questions
Q: How long does a prohibition notice stay in force?
A: Until the identified non‑compliance is corrected and the WHS officer signs off that the site meets the relevant standards. The notice will state a specific deadline.
Q: Can we appeal a prohibition notice?
A: Yes, you can apply for a review to the WHS regulator within the timeframe noted on the notice, but work must remain stopped until the review outcome is received.
Q: Do custom‑printed vests count as compliant?
A: Only if the printing does not obscure any required reflective surface and the vest still meets colour, class, and tape width standards. See our custom safety vests page for details.
Q: Are there any exemptions for temporary work?
A: No. All workers on a site, even on a one‑day contract, must wear compliant hi‑vis PPE.
Keeping Your Site Notice‑Free
A prohibition notice is a warning that your site’s safety—and its bottom line—are at risk. By routinely auditing vests against the checklist, sourcing only from reputable Australian manufacturers like those backed by Sands Industries, and training supervisors to spot faded or mis‑classed garments, you eliminate the most common triggers.
Key take‑aways:
- Know the exact class your workers need and stick to it.
- Inspect colour and reflective tape every shift.
- Avoid cheap imports and oversized branding.
- Keep a stocked inventory of compliant vests for quick replacements.
