5.1 In cases where only a part of a 'tween-deck
or lower hold is used for the stowage of FIBCs, measures should be
taken to prevent the FIBCs from shifting. These measures should include
sufficient gratings or plywood sheets placed against the FIBCs and
the use of wire lashings from side to side to secure the FIBC cargo.
5.2 The wire lashings and plywood sheets used
for securing should be regularly checked, in particular before and
after rough weather, and retightened if necessary.
