In addition to the class and division, some dangerous goods are also assigned packing
groups. These groups reflect the level of hazard that dangerous goods represent.
- The assignment of packing groups is done according to chemical and physical testing
requirements outlined for each class of dangerous goods in Part 2 of the TDG Regulations.
- There are 3 packing groups indicating the severity of the
hazard involved
- Packing Group I - Great Danger
- Packing group II - Medium Danger
- Packing Group III - Minor Danger
- Packing groups appear in column. 4 of schedule 1 and
as the name suggests, they specify the packing
requirements for that chemical.
