The smoke aspects in the escape routes for a three-level apartment are studied using the fire zone model CFAST 2.0. The smoke temperature and smoke layer interface heights in the corridors and staircases are analyzed. Performance of smoke control systems including ceiling vents (vent size of 1-4 m2) and smoke extraction systems (one to six air changes per hour) installed in the staircase are evaluated. Some experimental results reported in the literature are used to compare with the results predicted by this model. Finally, the effect of installing a residential sprinkler were discussed. Simulations on the fire suppression effect of residential sprinkler were performed using the fire protection engineering tool FASTLite with unsteady t2-fires. A comparison on the heat release rate of the smoke layer temperature for the cases with and without a sprinkler was made.
