Not really because your comparison doesn't in anyway answer the OP's proposition in which they state, smouldering hand luggage in an overhead locker vs pallet of batteries in the hold. The careful reading of the article meant it provided enough information for me to conclude that the volume of batteries in the hold compared to a few in the over head locker is the difference to why one fire could over whelm the fire suppression system and the other could have been managed safely.
I know what the BALPA directive says from reading it, but that isn't what is being talked about, so well done, 3 stars, but could do better.
(P.S. your getting a rant cause someone at work has pissed me off with their stupidity, again!)
