When it comes to transporting or storing dangerous goods in Aotearoa, Class 8 Corrosive Substances are one of the trickier classes to manage. They’re the ones that can cause serious damage to skin, metal and even infrastructure, not to mention the compliance headaches if you get it wrong.
Whether you’re moving industrial chemicals, cleaning products or battery acid, knowing how to handle Class 8 substances properly is key. Let’s break it down in plain English.
What Are Class 8 Corrosives?
Class 8 covers substances that chemically destroy living tissue or corrode metals. Common examples include:
- Hydrochloric acid
- Sulphuric acid (found in car batteries)
- Sodium hydroxide (used in cleaning products)
- Ammonia solutions
They might be in drums, IBCs or small containers, but the risks don’t shrink with the size.
What Does NZ Law Say?
In New Zealand, the main references for handling and transporting corrosives are:
- NZS 5433: Transport of Dangerous Goods on Land
- Land Transport Rule: Dangerous Goods 2005
These regulations lay out the must dos around packaging, marking, segregation and vehicle documentation.
Key Compliance Tips for Class 8 DG in NZ
Use the Right Packaging
You can’t just chuck corrosives into any old drum or bottle. Use UN approved packaging (e.g. 4G, 4GV, or plastic jerry cans) that’s compatible with the chemical, especially if you’re sending stuff by road or sea.
Proper Labelling
Every package must have a Class 8 hazard label, plus any subsidiary risk labels (e.g. if it’s also toxic or flammable). Labels must be durable, visible and match what's on the Safety Data Sheet (SDS).
Documentation Matters
When transporting corrosives, you need to complete a Dangerous Goods Declaration (DGD). This isn’t optional and incorrect paperwork is a fast track to non-compliance.
Segregate Properly
Class 8 DG can’t be stored or transported alongside certain other DG classes like Class Class 5.1 (oxidisers). Refer to the NZS 5433 segregation table to avoid any reactive combinations.
