1.1          CTUs are designed for intermodal transport. They are capable to be transferred from one mode of transport to another by rolling or lifting. A swap body can be carried on a road vehicle or on a railway wagon. A freight container can be carried on a road vehicle, on a railway wagon, on an inland barge or on a seagoing vessel. A road vehicle can be carried on a railway wagon, on an inland barge or on a seagoing vessel (ro-ro ship). A railway wagon can be carried on a seagoing vessel (railway ferry).

1.2          When CTUs are handled, it should be ensured that all handling devices such as lifting appliances and internal movement equipment are in good condition and suitable for the intended purpose.

1.3          On completion of handling, CTUs should be secured to the means of transport as appropriate for the specific transport mode.

1.4          A CTU which is leaking cargo or obviously unsafe for further transport should not be loaded onto a means of transport.
