Sequential Positive Pressure Ventilation For High-Rise Fires

Positive Pressure Ventilation (PPV) is a firefighting tactic that can mitigate the spread of fire and the combustion products to improve the safety of firefighters and civilians in wind-driven high-rise fires more than without PPV. In complex high-rise structures with multiple stairwells, the efficacy of PPV operation is greatly influenced by the fire location, fan deployment tactics, ventilation and fire-attack points which can drastically change the fire behavior. This paper describes a simulation-based study to analyze the influence of these parameters on the performance of PPV operation in complex high-rise structural fires. The results obtained provide qualitative trends for the effectiveness of PPV with respect to concerned parameters and establish the guidelines for sequentially ventilating the heat and smoke to reduce the thermal hazards to firefighters.
