Transporting of dangerous goods is a complex task that demands a high level of precision, compliance, and awareness. In this blog, we explore the most common mistakes businesses make when transporting hazardous goods and how to avoid them. For more information on the latest regulatory changes affecting hazardous goods transport, be sure to read our previous blog.
1. Improper packaging
Incorrect or inadequate packaging remains one of the top causes of incidents during the transport of dangerous goods. Packaging must meet strict UN standards and be suitable for the specific material being carried. Failing to secure containers properly can lead to leaks, spills, and even explosions, putting people and the environment at risk.
Tip: Always use certified packaging materials, and double-check compatibility with the goods being shipped.
2. Inadequate labelling and marking
Proper labels and markings are not just a regulatory requirement, they’re critical for safety. Every container must display the correct hazard class, UN number (In the UK, a UN number is a four-digit identifier assigned to dangerous goods by the United Nations, used to identify and classify them for transport), and shipping name, with labels positioned correctly and of sufficient size for visibility.
Common issues include:
- Missing or incorrect labels
- Labels applied in the wrong position
- Failure to include “Marine Pollutant” labels for sea freight
Tip: Cross-check labels against your shipping documents before dispatch.
3. Insufficient or incorrect documentation
Documentation errors are a frequent cause of transport delays and compliance failures when it comes to the transport of dangerous goods.
Common mistakes include:
- Missing the proper shipping name, packing group or tunnel code
- Inaccurate UN numbers
- Failure to provide container packing certificates
- Omitting emergency contact details
Falsely declaring the value of goods, intentionally or not, can also result in legal action.
Tip: Always review your Dangerous Goods Notes and supporting documents thoroughly, and include flashpoint data where required for flammable substances.
4. Non-compliance with transport regulations
Regulatory frameworks such as the ADR, IMDG Code, and IATA are continually updated. Businesses that don’t stay current with these regulations risk more than just fines, they risk liability in the event of an incident.
For example, under ADR 2025, documentation must now be located in the driver’s cab, and even drivers carrying limited quantities must hold formal training certificates.
Tip: Stay informed about regulatory updates and audit your processes regularly. Our blog on 2025 regulation changes covers everything you need to know.
5. Inadequate employee training
The people handling and transporting dangerous goods are your first line of defence against accidents. Yet many businesses still fail to provide adequate training, especially for those involved in loading, packaging or documentation.
Under updated regulations, all staff involved in the transport chain must receive training that matches the scope of their duties, including those transporting limited quantities.
Tip: Ensure all relevant employees have up-to-date, certified training in line with ADR and other applicable codes.
6. Poor identification and segregation of goods
Mistakes in identifying dangerous materials or failing to segregate incompatible substances can have catastrophic consequences. Incompatible items stored or transported together can react violently.
Tip: Refer to compatibility charts and always double-check the classification of materials prior to packing or loading.
