- (1) No hazardous material may remain on the outside of the Flexible Bulk Container; and

- (2) Each Flexible Bulk Container must be securely fastened to or contained within the transport unit.

- (3) If restraints such as banding or straps are used, these straps must not be over-tightened to an extent that causes damage or deformation to the Flexible Bulk Container.

If the Flexible Bulk Containers do not completely fill the barge, adequate measures must be taken to avoid shifting of cargo. The maximum permissible height of the stack of Flexible Bulk Containers must not exceed 3 containers high.
