Not to resurrent the "dead horse," but I want to add something. I've been in several situations where fire alarms went off in hotels and rental condos. EACH time it happened, I didn't run around the room like a chicken with its head cut off (read: panic.) I calmly got dressed, grabbed my handbag and LEFT. It didn't matter to me what the PA announcement said. In some cases, it was a minute or two BEFORE any announcement was made. Sorry, but I'm not going to stand around waiting for "instructions." I've hiked my ass OUT of the room, down the stairs and into the lobby (or outside) until I was DAMNED sure everything was under control. In these situations, seconds count and wasting them waiting to hear "EVACUATE" and then be stuck evacuating with a crowd that may or may not be "panicking," is not something I care to do. I left my parents, brother and his family in a condo unit during one fire (NOT a false alarm). They were taking their sweet-ass time, brushing their teeth, combing their hair, gathering up stuff and WAITING to be told what to do. I told them to just leave everything and follow me, but when it was clear they didn't want to, I grabbed my kids and still in our pjs and barefoot, walked down 11 flights of stairs. The rest of the family eventually met up with us outside the building, but I was shocked at how nonchalant they all were. Especially shocking since most of my family is anal-rententive and follow authority to the letter. I guess human nature is weird. Again, if that makes me irrational or a chicken-you-know-what, so be it.
I'll go one further. After 9/11 I sat my kids down (who were about 8 and 10 at that point) and told them that if they were ever in a situation like that---it was perfectly fine for them to leave the premises. Remember, they were all in Catholic school and were "aware" of the authority that ran the school. I told them that I would worry about the consequences of them leaving the building under orders NOT to. I'd rather they were alive and in disciplinary trouble, then be a lemming and D-E-A-D.
