Abstract:

In high buildings fires, most of the casualties are situated at the top floors - asphyxiated because of the smoke and hot gases - although the fire occurred at a lower floor. The smoke and hot gases travel from one floor to another mainly using the stair shaft. If this stair shaft would be pressurized, then the people at the top floors will be able to use the stairs for evacuation, as smoke and hot gases will find other way to dissipate. The research below uses a fire modeling on a high building, to assess and approximate the influence of positive pressure ventilation.

Keywords:

ventilation in fires, FDS, firefighting, positive pressure ventilation.
