99.9% of the time water entering the E&E will have no effect, it is quite common on freighters
Sorry have to completely disagree with that statement. There was an incident either BA or QF can't remember, that nearly became a smoking hole because of water getting in the E & E bay, toilet or galley flooded and the drip tray was cracked. I'm sure if you did a search you'd find it on here somewhere.
We have strict guidelines when loading freighters in rain, L1 closed as much as possible, all freight double bagged, top layer removed at the main deck door to prevent any water getting in, buckets and/or mops to removed water from the top of freight if need be.
better to be late than never!
