Notes for regulation 18
1 The assignment of particular dangerous goods to a Packing Group indicates the degree of danger, and the level of containment required for, the goods. The Packing Groups, and the degree of danger they indicate, are the following:
(a) Packing Group I (substances presenting high danger);
(b) Packing Group II (substances presenting medium danger);
(c) Packing Group III (substances presenting low danger).
2 The Packing Group of a substance can be determined from the Dangerous Goods List, although in some cases it is also necessary to refer to Chapter 3.3 of the ADG Code (the List identifies those cases).
