ok
To that I would say.
It is not up to the pilot to inspect all packages, naturally.
It is the job of the shipper and those who handle the shipment on the ground before it ever gets to the aircraft.
Load the lithium in the unpressurized section of cargo and isolate it , only thing i can think of.
Li batteries are not dangerous with proper packing. This is a shipper issue.
I suppose any dangerous thing is possible other than with batteries.
Accidents happen for all sorts of reasons.
If I knew there was a lithium shipment ?? yes, I would go look at the boxes. give them a good shake, see if anything moves around inside, especially if these are originating from outside china or USA,
Anybody in their right mind engaged in commerce sending these batteries is not going to just dump them all together in a box.
