and what if they are running towards an area where there is danger or a fire? it wasn't just two doors opposite eachother, they had to go through double doors to access the corridor then out the other side exposing themselves to the fronts of other rooms!
i thought the idea was to use the nearest exit to get out and safe asap.
Consider the following:
Route 1 - students leave by the closest exit and walk half-way around the building, arriving at the assembly point in 2m40s.
Route 2 - students pass that door and use another one which puts them on the other side of the building, arriving at the assembly point in 1m20s.
The objective is not to clear the building, but to verify that you have done so - this does not happen until every person has arrived safely at the assembly point, so the aim is to leave the building in whatever way achieves that in the least amount of time; using my example above, this would be route 1.
Also consider that if the fire is causing 3rd floor windows to blow out, raining glass down on the pathway underneath, walking along a 1st floor corridor might be safer than being outside.
This is the advice we were given when reviewing our evacuation routes recently.
I have to agree with vikpaw, I've also been told to exit by the nearest door and get out of the building as quickly as possible.
It covers that possibility that the extra few steps could lead to a nice warm fire making friends with your body, it does however affect your lovely statistics, not that would you care if the fire got you.
There is always the risk that any route will mean you meet the fire - in those instances, you change your plans. BUT, if you know that the fire is in building 1, then surely the best route from building 2 is the one which gets you to the assembly point in the shortest amount of time?
So we were told by our fire safety consultant anyway.
At my old place I was on the H&S panel for a bit.
One fire drill we blocked a staircase, and told everyone that attempted to leave that way the fire was in that staircase. It caused all sorts of problems, and proved that people needed a reminder of their alternative exit points!
We thought about firing off the smoke machine from drama, but were worried it might cause a panic!
i still think, get out as quick as possible by the nearest exit. every fire procedures document i've ever read says leave by the nearest exit. keep clear of the building etc.
accounting for everyone is not easily possible, that is part of the reason for this thread, we can never know who may be in or come into the building without being registered or accounted for. since we are likely to have incorrect data and the fire dept. wont rely on our registers anyway, the best thing to do is get people out of the building and away from possible danger. the fire dept. will sweep the local area.
