Compliance

Complies with NZS/AS 1319:1994 and NZS 5433 (Transport of Dangerous Goods on Land). Required for all bulk diesel storage and transport.

The 3Z UN 1202 code identifies diesel as a flammable liquid (Class 3) that requires specific firefighting and protective-equipment responses. Our post Understanding HAZCHEM Signs in New Zealand & Australia explains what each part of the code means and how it ensures correct emergency handling.

Diesel is classed under Class 3 – Flammable Liquids, along with petrol, kerosene and aviation fuel. Learn the differences between each class, and why the right placard matters, in Understanding Dangerous Goods Classes 1–9.

If you’re running tankers or storing diesel onsite, you’ll likely also need an Emergency Information Panel (EIP) displaying UN 1202 details. Our article Emergency Information Panel Signs Explained shows what’s required under NZS 5433 for complete site compliance.

Magnetic mounting option for the Hazardous 3Z 1202 DIESEL Sign

Flexible, vehicle-grade magnetic placards with the Hazardous 3Z 1202 DIESEL Sign printed on premium vinyl, laminated, and mounted to automotive magnetic sheeting. They stick to ferrous steel panels and remove without residue—ideal for vehicles that only carry DG sometimes.

Who they’re for

• Contractors / couriers who transport Dangerous Goods occasionally

• Hire or multi-use vehicles (no permanent signage)

• Sites that swap classes depending on load (quick changeover)

• Magnet: vehicle-grade sheet, 0.8–1.0 mm thick (30–40 mil), high-energy.

• Face film: outdoor self-adhesive vinyl + UV laminate (gloss).

• Operating temp: suitable from winter cold to summer heat (typical automotive range).

Where they work (and don’t)

• Works on: painted steel panels that are flat, clean, and smooth.

• Doesn’t work on: aluminium, stainless, plastics, composites, heavy body filler; vinyl wraps, ceramic coatings, heavily textured paint.

• If customers have aluminium doors/ute trays, suggest self-adhesive or rigid ACM instead.

Fitment checklist

1. Clean & dry the panel (no wax/polish).

2. Warm, flat magnet—no curl.

3. Apply to flat steel only; press from centre out.

4. Do not bridge panel gaps, ribs or sharp curves.

5. Remove daily to clean/dry both surfaces; store flat.

6. In heavy rain/highway speeds, check edges haven’t lifted.

Care & maintenance

• Remove and wipe after wet weather; store flat (never rolled tight).

• Move position slightly each week to avoid differential fading.

• Avoid use on freshly resprayed paint (allow full cure).

Compliance note

• Magnet is a mounting method. The operator must ensure placards are the correct class, size, and securely affixed for the journey. Some carriers or site rules may require permanent/rigid placards—check your procedure.

• Why you need the correct Hazard sign

NZS/AS 1319:1994 advocates simplicity and clarity in safety signage. To be effective, they should be easy to read and interpret at a glance.

The Standard is about the use of legible text and appropriate, simple symbols.

By simplifying the message, it reduces the risk of misinterpretation, which increases the chances of the sign’s warning or instruction being followed.

Enhancing the signs visibility through placement and colour

Placement and visibility will play a crucial role in the efficiency of safety signs.

The standard states that signs must be positioned near the hazard they are warning about, which ensures that the safety message is relevant. Also it advocates the use of contrasting colours for the background and lettering. This attention to the colour scheme will increase visibility and readability from a reasonable distance, which ensures the message is accessible.
