Tunnel Fire

1. The Clos Tunnel Fire in France in 1971

In March 1971, a French freight train collided with an oil tanker train near the north entrance of the Clos Tunnel. The oil tanker train exploded and caught fire, killing the freight train driver and assistant driver . Firefighters rushed to the scene and, with the close cooperation of the assistant driver of the oil tanker train, decisively separated the burning part of the oil tanker train from the burning part and pulled it out of the tunnel, preventing the accident from spreading. The burning oil tanker burned for a whole day and night, causing part of the tunnel to collapse. It was reopened to traffic after 96 days of repair .

2. The 1972 Hokuriku Tunnel Fire in Japan

At 1:30 a.m. on November 6, 1972, the Japan Express No. 50 passenger train was running at a speed of 60 kilometers per hour on the Hokuriku Main Line. When it reached the Hokuriku Tunnel (13.8 kilometers long) between Tsuruga and Imajo Station, the 11th dining car caught fire. The accident caused heavy casualties, with 782 passengers and crew members on the train, including 30 deaths and 714 injuries . According to the investigation and judgment of the Fukui District Court, the accident was caused by a leakage caused by poor wiring of the electric heating under the seats in the dining car smoking room.

3. The 1979 Yaizu Tunnel Fire in Japan On the evening of July 11, 1979, a fire broke out in the 2,050-meter-long tunnel between Shizuoka and Yaizu, Japan, 400 meters from the exit of Yaizu due to a collision between two trucks and the following vehicles, killing 7 people, injuring 1 person, and burning 174 vehicles. The fire occurred 400 meters from the exit, that is, more than 1,520 meters from the entrance. There were a large number of following vehicles within this distance. The smoke was thick and spread quickly during the fire, making it difficult for the following vehicles to retreat and evacuate in time. The fire burned until 10:30 on July 20, burning for nearly 10 days , before it was confirmed to be completely extinguished.

4. 1983 San Francisco Oakland Highway Tunnel Fire

In 1983, in the Oakland Highway Tunnel in San Francisco, the United States, a car collided with a bus in front of it and caught fire. A high-speed tanker truck behind it hit the two cars, and gasoline leaked, causing the fire to spread. The accident caused 7 cars to burn, 7 people to die, and 9 people to be injured .

5. The Shilishan Tunnel Fire on the Longhai Railway in 1987

At 7:34 on August 23, 1987, the No. 1818 freight train from Lanzhou Station was passing through the Shilishan No. 2 Tunnel at 1724 km 461 m between Lanzhou East and Sangyuan on the Longhai Line. The rails broke, causing six or seven tank cars behind the locomotive to turn over, and 16 tank cars caught fire in the tunnel. The fire burned for a day and a night, causing the Tianlan section of the Longhai Line to be interrupted for 201 hours and 56 minutes, 3 escorts died , 23 trucks were scrapped, 179 meters of tunnel cracks were damaged, 763 meters of track were damaged, and direct economic losses were 2.4 million yuan. The accident was caused by the failure to replace the fatigue damage of the rails in time.

6. 1987 Sproul Tunnel Fire in the United States

At 12:50 on November 5, 1987, the conductor of a train running through the Sproul Tunnel (located in West Virginia) reported a small fire in the woods not far from the tunnel entrance. 20 minutes later, another train running in the same direction also reported a fire in the east of the tunnel. Obviously, the air flow formed a strong wind with the passing train, and the burning leaves and leaves were swept into the tunnel and ignited the wooden guardrails of the tunnel. The rescue fire brigade arrived at the scene of the accident 40 minutes later, but it was impossible to extinguish the fire. The flames had spread from both sides of the tunnel entrance, forming a thick smoke screen. The fire was out of control, and the last resort was to let all the combustibles in the tunnel burn for a while until they went out by themselves.

7. The 2014 Jinji Expressway Yanhou Tunnel Fire in Shanxi Jincheng

On March 1, 2014, two tank trucks transporting hazardous chemicals rear-ended each other in the Yanhou Tunnel on the Jinji Expressway in Jincheng, Shanxi Province, causing methanol leakage from the front vehicle. During the driver's handling process, the methanol caught fire and burned, and the vehicles and coal and other cargo in the tunnel were ignited and exploded. The accident caused 31 deaths and 9 missing persons . The accident exposed that the main responsibility for production safety of the transportation enterprise involved in the accident was not fulfilled, the internal management was chaotic, and the management was replaced by subcontracting; the drivers and escorts of the hazardous chemical transport vehicles involved in the accident had weak safety awareness and did not operate according to the operating procedures; the coal inspection station set up 3.8 kilometers away from the tunnel exit was not conducive to the rapid passage of vehicles in the tunnel; the relevant local governments and their relevant competent departments did not supervise and manage effectively, etc. In addition, it also exposed some weak links in the emergency response work of tunnel accidents.

8. Maoliling Tunnel Fire in Taizhou, Zhejiang Province in 2019

At 18:27 on August 27, 2019, at 1607 km + 400 m on the G15 Shenyang-Haikou Expressway in the Fujian direction (Maoliling Tunnel is 3.7 km long, and the accident occurred in the middle of the tunnel), a heavy semi-trailer caught fire due to spontaneous combustion of its tires, and the smoke caused by the fire was so heavy that passing vehicles were stopped at the scene and could not pass. 36 trapped people at the scene of the accident were sent to the hospital, of which 5 died after ineffective rescue efforts in the hospital, and 8 were seriously injured .

Tunnel fire escape method

First, if you encounter a fire in a tunnel ahead while driving, you should evacuate the vehicle in time, place a warning sign behind the vehicle, and then flee in the opposite direction of the fire and smoke.

Second, when escaping, cover your mouth and nose with a towel or clothing (wet it with water is better) to filter out smoke and prevent poison. It is best to bend down and walk, because when a fire occurs, the smoke and poison gas diffused in the tunnel are initially unevenly distributed, thicker at the top and thinner at the bottom, and the temperature distribution is also high at the top and low at the bottom; don't shout loudly, otherwise you will inhale more smoke and toxic gases.

Third, most long tunnels have emergency exits that lead directly to the ground. The location of the emergency exit is usually marked at the tunnel entrance and exit, and there are also signs inside the tunnel. This evacuation passage should be flat, simple, without intersections, with emergency lighting and smoke exhaust equipment. If there is a fire in the tunnel, it is most appropriate to escape to the emergency exit that leads to the ground.

Fourth, if you are trapped in a car, you can quickly and decisively use sharp objects such as a fire hammer or high heels to break the windows and escape from the burning area.

Fifth, if a fire occurs in a subway tunnel, remember to run upwind, that is, run against the wind. Because a natural "lying" ventilation chimney is formed in the tunnel, there is air flowing inside. In addition, after a fire, the subway will activate the emergency procedure, and air will be quickly ejected at one end of the accident train, while smoke will be violently ejected at the other end, resulting in strong air convection, and toxic smoke will flow downwind.
