General Provisions: Scope, Responsibilities, and the Structure of the DGR
What this domain covers
General Provisions is the "constitution" of the Dangerous Goods Regulations. It defines who is bound by the rules, how the rules are structured, the shipper's and operator's responsibilities, training obligations, and the exceptions and State variations that modify the baseline requirements. Questions here test your grasp of the framework rather than the detail of a specific entry.
Concepts to master
- Shipper vs. operator duties. The shipper classifies, packs, marks, labels, and documents; the operator accepts, handles, loads, and provides information. Responsibilities do not transfer away from the shipper because an operator accepted the shipment.
- The DGR as a layered document. Sections 1-9 plus appendices; the "shall/must" language indicates mandatory requirements. Note how State and operator variations sit on top of the base rules.
- Variations. State variations (published by the country) and operator variations (published by the airline) can be more restrictive than the DGR but never less. A common trap is assuming an operator variation can relax a State requirement.
- Training. Personnel must be trained commensurate with responsibility, and recurrent training is required at defined intervals. Questions often test who needs training (including ground handlers and acceptance staff) rather than just flight crew.
- Dangerous goods in excepted/limited quantities and the concept of "dangerous goods forbidden unless..." Understand that some articles are forbidden in all circumstances, while others are permitted only under specified conditions.
Traps and a rule of thumb
Traps include confusing "should" with "shall," mixing up who is responsible for a step, and forgetting that variations are cumulative and restrictive. Rule of thumb: when in doubt, apply the most restrictive applicable requirement - State variation, then operator variation, then the base DGR - and remember the shipper owns the correctness of the declaration.
Worked example: An operator's variation permits a package that the destination State forbids. Because State variations prevail and cannot be overridden by an operator, the shipment is not acceptable.
