Packaging, IBCs, Large Packagings, Tanks, and Portable Tanks
Selecting the right packaging
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. IBCs and large packagings have their own testing and marking regimes. Portable tanks and road tank vehicles must meet the construction and testing requirements referenced in the Code. The general provisions require that packaging be strong enough for the voyage, compatible with the contents, and closed so that no leakage occurs under normal conditions of transport.
Traps candidates fall into
- Using a packaging that is not the one specified in the packing instruction for that PG.
- Ignoring the UN mark or using a packaging beyond its tested mass or capacity.
- Confusing IBC requirements with those for large packagings.
- Assuming a portable tank can be used wherever a drum is allowed; tank instructions are entry-specific.
Worked example
A PG II liquid lists packing instruction P001 and portable tank instruction T4. A drum marked for the correct PG and within its tested capacity is acceptable; a portable tank must meet T4. A packaging marked for PG III cannot be substituted for PG II.
