Mobile Ventilation as a Tactic Resource at Tunnel Fires
An emergency operation in case of a tunnel fire can easily become a complex operation. The objectives are to save people in danger, save the tunnel and its installations as well as vehicles trapped inside the tunnel and also, if it’s possible and necessary, reduce the effects on the environment. The strategy and the tactics in an emergency operation are very much depending on the specific tunnel, the fire behaviour and the resources from the fire brigade. One of the key factors is to ventilate the tunnel in order to take the smoke away from the people in danger or to support the fire fighting operation. The possibilities to effectively ventilate the tunnel depend on the knowledge of the fire brigade, the available pre-installed or mobile installations and equipment for ventilation and the tactical approach chosen. In tunnels with only natural ventilation or to improve existing ventilation in tunnels, mobile fans can be used. The possibilities to redirect the flow are dependent of the capacity of the fans, the tunnel geometry and the counteracting forces from outside wind or the thermal buoyancy from the fire. In this paper the tactical approach with ventilation is further analysed and the possibilities and limitations are studied and discussed.
