Customer Testimonials
What is a Dangerous Goods Container
A dangerous goods container is a specially designed storage unit built to safely contain hazardous goods and substances that pose risks to health, safety, property, or the environment.
Unlike standard shipping containers, DG containers incorporate additional safety features such as spill containment systems, specialised ventilation, fire suppression capabilities, and enhanced security.
Choosing the Right Dangerous Goods Container
Sizing
Choose the container length that matches your operation’s scale. Our 20ft units are ideal for smaller sites with limited space yet provide substantial storage capacity. For industrial-scale requirements, our 40ft containers deliver maximum capacity while maintaining all essential safety features.
Grades
We offer dangerous goods containers of different grades, from single-trip A-grade to as-is C-grades. Our new and used containers are all compliant with HSNO regulations and fit for storage. However, our used containers lack a lockbox and may look more weathered.
Modification
We can tailor standard dangerous goods containers to your needs. Climate control systems protect temperature-sensitive materials from degradation, while integrated shelving and racking maximise space utilisation for organised inventory management.
Maintenance and Inspection Guidelines
Maintain compliance and safety with:
- Regular leak tests and pressure checks to ensure container integrity
- Routine inspection of ventilation systems and spill containment zones
- Scheduled verification that all emergency equipment remains functional and accessible

FAQs About Dangerous Good Containers
Our containers accommodate a wide range of hazardous materials, including flammable liquids, corrosives, toxic substances, and oxidising agents, with customisation options for specific dangerous goods classes.
The primary difference is capacity—40ft containers provide twice the storage space, offering greater economies of scale for businesses with larger storage requirements while maintaining identical safety features.
DG containers must comply with the Hazardous Substances and New Organisms Act (HSNO), WorkSafe NZ guidelines, and industry-specific regulations, all of which our containers meet or exceed.
We recommend quarterly visual inspections and annual comprehensive assessments, with specific schedules varying based on the hazard classification of stored materials.
