IMDG Dangerous Goods Awareness study plan
IMDG Dangerous Goods Awareness · Give each week a clear focus.
8 weeks · About 7 hours per week
IMDG Code framework, scope and application & Classification of dangerous goods
Map the structure of the IMDG Code volumes, supplements and the role of the Dangerous Goods List as the central lookup tool
Explain how the UN Model Regulations feed into the IMDG Code and where modal differences arise
Define the nine hazard classes and the meaning of division, packing group and subsidiary risk
Assign class, division and packing group to at least 15 substances using only their physical and chemical descriptions
Your checkpoint
A one-page hazard class and packing group decision aid plus a scored 15-substance classification worksheet with at least 12 correct
Classification of dangerous goods
Apply precedence of hazard rules to substances that meet criteria for more than one class
Distinguish the three packing groups by degree of danger and justify each assignment
Interpret transport condition statements for self-reactive substances and organic peroxides at a conceptual level
Identify marine pollutants and explain the basis for that determination
Recognize class 1 compatibility group logic without memorizing the full table
Your checkpoint
A written classification rationale for 10 mixed-risk scenarios, each citing the class criteria and packing group logic used
Dangerous Goods List and special provisions
Read a Dangerous Goods List entry column by column and state what each column controls
Locate the correct entry for a named substance and explain how to resolve entries marked as generic or not otherwise specified
Interpret special provisions and identify which ones change packing, stowage or quantity limits
Distinguish the roles of the segregation groups and the index of names
Trace how a special provision flows into a practical handling instruction
Your checkpoint
A completed lookup log for 12 substances showing UN number, proper shipping name, class, packing group, special provisions applied and the resulting practical impact
Packing, marking and labelling
Select the correct packing instruction for a given entry and explain how packing provisions modify it
Identify the marking elements required on packages and overpacks and where each is placed
Match hazard labels and placards to class and subsidiary risk, including marine pollutant marking
Explain the difference between non-specification and specification packaging in practice
Check a described package against packing, marking and labelling requirements and list every defect
Your checkpoint
A defect-finding exercise on 8 described packages, correctly identifying at least 90 percent of the intentional errors in packing, marking and labelling
Documentation and declaration
Draft a complete multimodal dangerous goods declaration from a shipment brief
Verify a declaration against the Dangerous Goods List and correct every field error
Explain the container packing certificate and who signs it and why
Describe documentation retention and the information that must accompany the transport unit
Identify the declaration errors most often linked to incidents and delays
Your checkpoint
Two declarations produced from shipment briefs, plus a corrected version of a deliberately flawed declaration with each correction annotated
Stowage, segregation and handling
Apply the segregation table and explain when segregation is not required
Distinguish the four segregation terms and translate each into a practical stowage instruction
State the rules for stowage on deck versus under deck and for cargo transport units
Explain securement, ventilation and the handling precautions for classes with specific stowage needs
Resolve a mixed-load scenario into a compliant stowage and segregation plan
Your checkpoint
A segregation and stowage plan for a 12-line mixed load, with a written justification for each segregation decision
Emergency response and incident reporting & Training, responsibilities and safety culture
Outline the immediate actions for a spill, fire and leaking package incident, in the correct order
Explain the role of the Emergency Response Procedures for Ships Carrying Dangerous Goods and the Medical First Aid Guide
Describe the reporting chain for a dangerous goods incident, including what must be recorded and to whom
State the training obligations for shore staff and shipboard personnel and the record-keeping that proves them
Explain how near-miss reporting and a questioning attitude reduce dangerous goods risk
Your checkpoint
A one-page incident response and reporting flowchart plus a training matrix covering five job roles with required competencies
Limited quantities, excepted quantities and exceptions & IMDG Code framework, scope and application & Dangerous Goods List and special provisions
Apply the quantity thresholds for limited quantities and excepted quantities and state the reduced requirements for each
Identify the marking for limited quantity and excepted quantity packages and the documentation reliefs
Explain the exceptions available for consumer commodities and for equipment containing dangerous goods
Revisit the Code framework and Dangerous Goods List with a timed mixed-question set covering all domains
Review every missed question and close each knowledge gap with a cited rule reference
Your checkpoint
A full timed mock exam with a written error log that maps every wrong answer to a domain and a specific Code reference
Milestones
Week 2: Classify 15 unseen substances with at least 80 percent accuracy on class, division and packing group
Week 4: Complete a full package compliance check within 20 minutes with no missed labelling error
Week 6: Produce a compliant declaration and a segregation plan for the same mixed load without reference notes
Week 8: Score at least 85 percent on the timed mock exam and show a closed error log with no repeated mistakes
