That should not be normal. There should be evac chairs at the top of the stairs that slide down the stairs, therefore they can leave at the same time
No, as that will limit volume of others down the stairs. So for example you may get 20 people out in 90 sec or 12 plus 1 in an exact chair. Again, it’s a numbers game, you have to scenario plan for max numbers out quickly, nothing personal and has zero to do with personal worth as someone else claimed.
You do know that in hospitals not everyone will be evac’d right? I did those drills for umpteen years. There’s always a group that is going to put others at risk and they are left in situ and instruction given to firefighters as to how many and location (s). No one is allowed to stay with them. They are worth no less than anyone else, it’s just logistics. Obviously you try your best and their are a sub-set who, in certain situations may even be evac’d via helicopter from roof but that’s not possible in all scenarios and not every patient in a bed could be moved like this plus it’s also limited to scenario/time/number of choppers.
In drills at school, my child at the time, who may/may not have needed assistance depending h on how they were travelling at the time, but still would have been slower, went last. Funnily, if she had a male teacher they always generally scooped her up and carried her (very very slight) at the end of everyone else. In one situation in an actual emergency (turned out to be false alarm but they didn’t know, just knew not a drill), one female teacher did also but she was a large and strong person and no doubt the adrenaline kicked in. However, a typical size female likely would not have and I’m guessing if push came to shove, do to speak, and there were flames licking their arse, the average teacher would have no doubt left them in their wake. You sort of have to be okay with that on the realism scale.
