I was a medic in the army, deployed to Iraq, have been trained in mass casualties, evacuations, etc.
I have actually HAD to do those in real life. No matter how planned a situation is, you can't plan for everything. But you CAN offer a plan B. I am not saying NOT to go to the muster station. I am saying that they need to have a back up for every muster station. Not even saying it needs to be at the lifeboats, but if everyone is running from a burning theater that is my muster station, and they didn't tell me where to go in the evet that my muster station is not accessible, then should I just stand there? No! But where exactly should I go? Against the crowds to the burning theater? Against the crowds to the upper deck staterooms? Out to the lifeboats that may be in a completely different direction than where my lifeboat is located? Again, causing chaos against the crowds.
That's what my point is getting at. Telling me to just go to my muster station isn't good enough (clearly I would go because that's the protocol), but my point is they need to give a secondary location in the event that a specific muster station is not accessible.
Being that I have had to plan for evacuations, mass casualties, etc. I can tell you right now, a blanket response of just go to your muster station is not the best response.
Talk to your CM and ask them where you should go if the muster station is not accessible. I asked mine, and guess what, they had to ask their supervisor after his initial response of "just come here". When I explained that what if "here" is on fire where should we go, he paused and went to ask his supervisor.
So don't tell me they are all trained in this and know what they are doing. If it was an emergency and I had to ask where we should go, this CM would have been clueless thus causing more panic.
