Use of mobile tunnel ventilation devices to assist emergency services during fires in underground road systems
Constantly rising volumes of traffic mean that the risk of accidents on open roads and in tunnels is also steadily on the increase. The danger of vehicles catching fire in underground road systems is exacerbated by the fact that the smoke and toxic gases emitted soon reach dangerous levels. This often prevents emergency services from reaching the scene of the accident fast enough to rescue people and fight the fire, and also hampers them during cleanup operations. Mobile ventilation devices can be of considerable assistance to the emergency services by affecting the natural air currents in the desired way or boosting the capacity of the stationary ventilation systems in place. Having evaluated the operational conditions required, mobile tunnel fans were designed and their efficiency validated using CFD calculations. In many field tests, some under emergency conditions, the results of the theoretical considerations were examined and the handling checked. It was therefore proved that if these ventilation devices are taken into consideration in operation procedures, they can be a great help to the emergency services and enable them to reach the scene of the accident much faster.
