IMDG Dangerous Goods Awareness

No single global examining body runs an "IMDG awareness" exam. Awareness training and assessment are delivered by training providers, classification societies and companies under their own schemes. Check with your employer or chosen provider about their assessment format, and confirm any regulatory requirement with your national maritime administration.

This varies by provider. Awareness courses commonly run from a few hours to two days, with a short multiple-choice assessment at the end. Training providers publish their own durations and timings, so ask the provider directly rather than relying on second-hand figures.

There is no universal pass mark. Each training provider or company scheme sets its own threshold, often a percentage of a multiple-choice paper. Ask your provider for the pass criteria before you start so you know what is expected.

Retake rules are set by the provider, not by the IMDG Code. Many providers allow a resit, sometimes for a fee and sometimes after a waiting period. Confirm the resit policy in writing when you book.

Awareness papers are designed to be passable after proper training. They test recognition and correct application of Code concepts rather than deep calculation. The main challenge is the volume of terminology and the need to find information quickly in the Dangerous Goods List.

Start with the framework: what the Code is, how it is amended and who is responsible for what. Then learn the nine classes and their divisions, followed by the Dangerous Goods List columns and special provisions. Finish with packing, marking, labelling, documentation, segregation, emergencies and the limited and excepted quantity exceptions.

Common errors include confusing packing groups, misreading the Dangerous Goods List columns, forgetting that the transport document must use the proper shipping name, and assuming limited quantities are exempt from all marking. Segregation table misuse and unclear emergency contact details also cause frequent mistakes.

Study the edition currently in force for your trade. Amendment 42-24 became mandatory on 1 January 2026, so materials referencing older amendments may be out of date. Ask your provider which amendment their course follows and check the IMO website for the current status.

No. Awareness training gives you a working understanding of the rules so you can recognise dangerous goods issues and escalate correctly. It does not replace the function-specific and safety training required for people who actually pack, document, handle or stow dangerous goods.
