Hazchem 3Z 1202 vs Hazchem 3Z 3082 vs UN 3082 — Explained

Diesel signage can be confusing that’s why we created the “Which Diesel Sign Do I Need?” resource — there are multiple codes, colours, and layouts that all look similar but serve very different purposes. If you’re not sure whether you need a Hazchem 3Z 1202 sign, a Hazchem 3Z 3082 sign, or just a UN 3082 environmental placard, this guide will make it clear.

Getting this right isn’t just good practice — it’s a compliance requirement under HSNO, NZS 5433:2020, and NZS/AS 1319:1994.

  • Use Hazchem 3Z UN 3082 when environmental protection is also a priority, such as near stormwater drains, rivers, or sensitive sites.
