What should we do when there is a fire in the tunnel? Is there anything that can guide us to escape in the dark tunnel? In fact, there are many traffic safety facilities installed in the tunnel. I don’t know if you have noticed that there are not only tunnel induction lights to guide vehicles forward, but also many Solar Traffic Signs. The tunnel evacuation sign is one of them. Its The function is to prompt and guide people to escape from the tunnel safely when a traffic accident occurs in the tunnel.
In recent years, with the rapid development of my country's expressway construction, highway tunnels have become longer and longer, and have become an indispensable "green channel" in people's lives. According to data, most of the people involved in the fire scene in the tunnel were suffocated to death by smoke, such as Unfortunately, when encountering a tunnel fire, how to get more survival opportunities for yourself, Ruichen warmly reminds the general public: In the case of a fire with LED tunnel induction lights and LED tunnel electric signs, please follow the instructions of the tunnel electric signs. Instruct to escape. The tunnel evacuation sign at this time is the Solar Traffic Signs of our life.
First, if you encounter a fire in the tunnel ahead while driving, you should evacuate the vehicle in time, place warning signs behind the vehicle body, and then flee in the direction opposite to the fire and smoke flow. Escape to the safe exit according to the prompt of the tunnel evacuation sign.
Second, when escaping, cover your mouth and nose with a towel or clothing (wet with water is better) to filter the smoke and prevent poison. It is best to bend down and walk, because when a fire occurs, the smoke and poisonous gas diffused in the tunnel are initially unevenly distributed Yes, the top is thicker, the lower part is thinner, and the temperature distribution is also up and down; don't shout loudly, otherwise you will inhale more smoke and toxic gases.
Third, most of the longer tunnels have safety exits directly leading to the ground. The location of the safety exits is generally marked at the entrance and exit of the tunnel, and there are also tunnel electric and optical signs in the tunnel. This evacuation passage has a tunnel evacuation sign hanging on it. The route is simple, without intersections, with accident lighting and smoke exhaust equipment. If there is a fire in the tunnel, it is most appropriate to escape into the safety exit leading to the ground according to the prompts of the tunnel evacuation signs.
Fourth, if you are trapped in the car, you can quickly and decisively use sharp objects such as fire hammers and high-heeled shoes in the car to break the car window to escape from the fire. Escape to the safety exit according to the prompt of the tunnel evacuation sign,
Fifth, if the fire occurs in the tunnel, keep in mind that running to the upwind means running against the wind. Since a natural "lying" ventilation chimney is formed in the tunnel, there is already air flow in it, and after the fire, the subway will start emergency procedures, and the airflow will be ejected quickly at one end of the accident train, while the other end will inhale the smoke. Strong air convection occurs, and poisonous smoke will rush to the downwind vent.
