A few years ago we were getting about one of these a month for 8 or 9 months. All flight attendant actions. Eventually enhanced training reinforcement got the better of the situation.
Was really a pain for me to get a relacement as sometimes they weren't available at the base and I would have to bring one in and explain status in the morning to the Mtce Super and Chief Pilot. Dangerous goods and all that. Brought one in from HKG once. Had a couple expedited through the raft shop - even that takes a considerable amount of time mostly due to inflation testing and packing.
I really hate slides blown for no good reason.
