A total flood fire suppression system is provided for transportation tunnels and other human-occupied environments, which employs a selective gas delivery method for supplying a breathable fire-extinguishing agent to a location closest to a fire site. The agent is produced from ambient air at site ...
Tunnel and Metro Fire Protection Webinars focus on design, solutions & technical innovations for improved fire performance of rail assets.
The Channel Tunnel also employs a novel firefighting strategy, whereby trains are driven to designated water-mist suppression zones in the event of a fire. In a worst-case scenario, this could entail a train with a fire being driven up to 15 km through the tunnel before reaching one of ...
For trains with steel body structures the HRR was less than 19MW and the fire duration longer and the ceiling temperatures tended to be lower than 800 °C (tests 4, 5, 12 and 13). For the passenger car, the highest temperature was between 210 and 480 °C and the HRR was up to 6...
Rescue stations have been newly designed in some super-long mountain railway tunnels of China such as over 30 km long, as a new type of strategic counteract design for fire accident in tunnels. Water mist fire suppression systems are needed to be installed in such rescue stations to control ...
The truck stopped 5 km from the French side of the tunnel, creating plumes of thick, hot smoke which were carried towards the Italian end of the tunnel, igniting two other lorries, including one carrying glue. The French government was already researching the installing fire suppression systems ...
Fire is definitely one of the most serious accidents that may occur in highway tunnels.The Cranee′s formula,which is used for high temperature cases,is analyzed and modified through combining actual fire conditions.Using the finite element method,the temperature field of a typical tunnel segment...

2.2. Fire scenarios In this paper, a full-size tunnel with length 250 m, width 10 m and height 5 m was built. And a rectangular section was adopted in this study. To imitate the ambient condition in actual tunnels, both openings were set as “open”, as shown in Fig. 1. In order...
