It is well known that the efficiency of the ventilation is extremely important in subway systems. The ventilation system is one of the main aspects of subway infrastructure when emergency situations involving fire or massive release of smoke and toxic gases occur inside the tunnels. Otherwise, the performance of the ventilation is the key factor of the subway systems when unfortunate events such as fires, chemical or biological attacks take place as in such situations a large number of victims can occur. The use of efficient ventilation systems, the existence of sufficient evacuation pathways as well as the knowledge by the intervention teams of the phenomena occurring inside a subway tunnel in the event of a fire is a great help for protecting and saving people's lives.
