Canada IMDG Marine DG study guide
Canada IMDG Marine DG · Work through your exam, one topic at a time.
The Canada IMDG Marine Dangerous Goods examination tests whether a candidate can apply the International Maritime Dangerous Goods (IMDG) Code to real shipments moving by sea into, out of, or through Canada. It is aimed at shore-side staff and crew who prepare, offer, accept, handle, or carry packaged dangerous goods: shipping and documentation clerks, freight forwarders, port and terminal operators, stevedores, surveyors, and ship's officers with cargo responsibilities. The Canada IMDG Marine DG study guide has 10 sections and about 2,640 words.
01IMDG Code Structure, Scope, and Legal Framework
The IMDG Code gives effect at sea to two international conventions. SOLAS Chapter VII makes the carriage of dangerous goods mandatory and points to the IMDG Code for packing, marking, labelling, documentation, stowage and segregation.
350 words, about 2 min02Classification: Hazard Classes, Divisions, Packing Groups, and Subsidiary Risks
The IMDG Code recognises nine classes. Class 1 explosives has six divisions (1.1-1.6) and compatibility groups.
328 words, about 2 min03Dangerous Goods List, Special Provisions, and Limited/Except Quantities
The Dangerous Goods List is the core reference. Each entry gives the UN number, proper shipping name, class or division, subsidiary risk, packing group, special provisions, limited and excepted quantity limits, packing instructions, portable tank and IBC instructions, stowage and segregation codes, and properties/observations.
257 words, about 1 min04Marking, Labelling, and Placarding
Packages carry the UN number, the proper shipping name (where required), the hazard label(s), and any special marks such as the marine pollutant mark or limited quantity mark. Labels are diamond-shaped, colour-coded by class, and show the class number; subsidiary risk labels are also applied.
269 words, about 1 min05Documentation: Transport Document, Packing Certificate, and EDI
The multimodal dangerous goods transport document must state the UN number, proper shipping name, class/division, subsidiary risk, packing group, number and kind of packages, total quantity, consignor and consignee, and any special provisions. It must include the shipper's declaration that the goods are properly classified, packed, marked and labelled.
259 words, about 1 min06Packaging, IBCs, Large Packagings, Tanks, and Portable Tanks
The packing instruction in the Dangerous Goods List tells you which packaging, IBC, large packaging or tank is permitted for the entry and packing group. Packaging must be of a design type tested and marked (UN mark) and must be used within its tested capacity and mass limits.
274 words, about 1 min07Stowage, Segregation, and Securing on Board
Stowage codes in the Dangerous Goods List tell you where goods may be carried: on deck, under deck, away from living quarters, away from heat sources, and so on. Segregation codes govern separation from other dangerous goods and from incompatible materials, using the segregation table and the "away from," "separated from," "separated by a complete compartment or hold from," and "separated longitudinally by an intervening complete compartment or hold from" distances.
226 words, about 1 min08Emergency Response, Fire Precautions, Spill Control, EmS and MFAG
The Supplement to the IMDG Code contains the EmS Guide (emergency response procedures for fire and spillage) and the MFAG (Medical First Aid Guide). Each dangerous goods entry in the List carries an EmS schedule reference (e.g., F-A, S-A) and an MFAG table number.
253 words, about 1 min09Transport Security Provisions and Security Awareness
The IMDG Code includes transport security provisions aimed at preventing dangerous goods from being used to cause harm. These cover security awareness training, security plans for certain high-consequence goods, and the principle that access to dangerous goods should be controlled.
206 words, about 1 min10Safe Handling, Loading, Unloading, and Personnel Training
Safe handling covers the whole chain: checking documents, inspecting packages and units, loading in the correct sequence, securing, and unloading without damage. Personnel must be trained in the hazards of the goods they handle, the meaning of labels and placards, safe handling procedures, and emergency response.
