DG stowage :
Particular caution is to be exercised when stowing dangerous cargo on board the vessel.
Any dangerous cargo presented for loading must be accompanied by a proper manifest and declaration as required by international regulations . Further this DG cargo must be acceptable for carriage as per IMDG code guidance. Reference here is made to the list of UN numbers restricted/prohibited for carriage on board particular vessels.
After confirming acceptability of the DG cargo, the plan must be checked for proper stowage and segregation. Although terminal and central planners should provide proper stow of DG cargo, the final responsibility always lies with the Master.
Reference shall be made to vessels Document of Compliance with special requirements for ships carrying dangerous goods for confirming that proposed DG classes are acceptable for stowage in planned locations on board.
Specific stowage requirements for DG cargo
(e.g. Clear of living quarters OR if under deck, in a mechanically ventilated space etc) may be verified from individual entries of dangerous goods list in the IMDG code.
DG segregation shall be verified for compliance with requirements of the IMDG code.
Caution must be exercised when using vessels stowage planning software for this purpose as it may or may not have comprehensive means of checking for bad stowage & segregation against the latest international requirements. It is advisable to manually check for compliance.
Segregation requirements of the IMDG code and any other local/national regulations must be strictly adhered to.
One must be aware that even DG cargoes belonging to the same class may have segregation requirements amongst them.
A good example is that of alkalis requiring to be separated form acids where as both acids and alkalis may belong to IMO Class 8. Such segregation requirement will not be found in the segregation tables of the IMDG code and only individual entries of the dangerous goods list in the code indicate the requirement.
