Sounds like a key consideration on where to load this container. Being a tanker-type I have no first-hand experience with container ops, is this considered when planning a load?[/quote]
There is IMDG code applied when loading all IMDG cargo.
So, first - separation of cargo is considered, and also segregation of cargo.
Flamable cargo (boxes) are separated from lets say - heat sources, etc…
But, this also means that you can have emtpy boxes loaded on top of IMDG cargo (no rule forbidding this), and you can have some other boxes below with some general cargo inside.
In that case - probably no rule is broken, but access to box which is on fire is limited.
Second: if you have this box on 3rd tier (very high above deck) the safety of crew performing such high altitude task is in question.
So in this case in real situation I would:
provide boundary cooling
check IMDG code for instructions (procedures specific for fire on certain type of IMDG cargo)
Check ISM guides for instructions on procedures (high altitude work / fire fighting / safety equipment to use, etc…)
contact DPA - with all info on hand, by emcy line and than by email.
Manouvre the ship to reduce wind effect. (bow thruster on if necessary, shaft generator off, two generators running, reduced speed etc…
Consider port of refuge if necessity develops
Take actions as per points 1 to 5, taking DPA advice in consideration. At all times would keep in touch with DPA.
@ mr 100ton:
For intended drill (since the question is about the execution of drill):
Check all IMDG code requriements and procedure according to UN number and class of cargo,
check all ISM guides to procedures
and check equipment on board.
Breif all the crew on all above. An explain each person duties
Execute the drill.
Make a report.
In case IMDG instructions are necessary, I will provide them on request, just give me exactly what type of lithium cargo it is (declaration on DG manifest), class, and UN number.
UN number is most important to establish procedure required.
Also, let me know if you have any cargo gear on board (for eventual jetisson of cargo_), but here I already see possible troubles… we can discuss it if you like!
