There is probably no class of building in which good fire planning and training can pay off more than in __ __.
Today, building codes only require that atria connect a minimum of __ floors without a minimum size requirement.
Building codes specify numerous requirements for atria:

Under lapse conditions, smoke will move __ and __ from the fire.
The wind exerts a pressure on the __ side of the building and suction on the __.
If the windows are out and the fire is on the __ side of the building, the suppression may be "a piece of cake."
Given the same fire, the windows out, and the fire on the __ side of the building, it may be impossible to move into the fire floor.
Stack effect is most significant in __ climates in the __ because of the great difference between the inside and outside temperatures.
Under winter conditions, stack effect causes a movement of air from the floors into the __ __, __, __ and so on in the __ portion of the building.
The greatest flow will be at the __ floor, with the flow gradually decreasing as the height of the floor above ground increases.
At a point about __ to __ the building's height, the flow is reduced to __; this is called the __ zone.
1/3 to 1/2
Above the neutral zone, the flow __ and travels out to the __ from the __.
In a sealed air conditioned building in the summertime, the stack effect is __ (and is often called a __ __ __).
Reverse stack effect
In such a case, the flow of air is __.
To complement the smoke barriers, corridors are a minimum of __ feet wide to accommodate the size and width of rolling hospital beds.
