Dangerous Goods Containers: Rules and Regulations in Australia

Any Australian business that deals in hazardous substances knows exactly how seriously authorities take regulatory compliance – and the severe penalties of non-compliance.

On-site storage is a key consideration, which is where dangerous goods containers come in. These aren’t just steel boxes; they’re precision-engineered assets designed to isolate hazards if an accident occurs.

In this article we’ll deliver a rundown of dangerous goods (DG) containers, and what you need to know in terms of Australian compliance, to help you protect your business, your assets, and most importantly your people.

Core Australian safety compliance

Key compliance considerations:

• Australian dangerous goods (ADG) code for transport
• Australian standards (e.g. AS1940, AS3780, AS4332)
• State-based occupational health and safety (OH&S) laws

A few different standards apply to DG storage. In terms of transport, containers must comply with the national Australian Dangerous Goods (ADG) Code. On-site storage, meanwhile, is typically covered by a combination of state-based occupational health and safety (OH&S) laws and relevant Australian standards.

A dangerous goods container may need to be customised when it transitions from transport to on-site storage, depending on what it will hold. Class 3 flammable liquids (e.g. paints, solvents and fuels) are covered by AS1940, for example. This standard states that the container’s internal bunded sump (more on that below) must hold at least 110% of the largest capacity container stored within it, or 25% of the total aggregate volume, whichever is greater.

By and large, using a certified dangerous goods container can greatly simplify workplace health and safety audits, as these units come complete with many of the design elements that state and national standards demand.

The architecture of containment: bunded floors

The bunded flooring mentioned above is a key design element of a dangerous goods container. It is an integrated, liquid-tight sump built beneath a galvanised steel grate floor, designed to catch and contain any leakage of the liquids held within.

The bund must be able to hold a specific percentage of the total stored volume of dangerous liquids, to ensure that a punctured drum or leaking IBC doesn’t endanger workers or contaminate the surrounding environment.
DG containers are also fitted with stainless steel valves that allow you to safely drain spills.

Ventilation and explosion mitigation

Gas leaks and the build-up of fumes can be far more difficult to navigate than liquid leaks. An accumulation of volatile organic compounds (VOCs) from paints and chemicals presents two main dangers: inhalation and ignition.

This issue is usually mitigated with natural cross-flow ventilation, in the form of heavy-duty louvered vents positioned low on one end wall and high on the other, which promotes the continuous movement of air.

Active (powered) ventilation is an option for particularly high-risk containers, such as those used for decanting, but any extractor fans and other electrical fittings must be intrinsically safe, to ensure they don’t produce a spark that could ignite fume-filled air.

Key takeaways:

• Dangerous goods can present inhalation and ignition risks
• Passive ventilation (louvered vents) can prevent the build-up of fumes
• High-VOC areas may require intrinsically safe active ventilation

Protect your operations with a DG container

While dangerous goods compliance is a legal necessity, this isn’t about dodging fines – it’s about keeping your business and your workers safe.

Dangerous goods containers come complete with many of the features that DG laws demand. If customisations are required due to the materials you’ll be holding inside or local rules and regulations, we’re here to help.
