How to escape from the fire in subway?

subway has become one of the important means of transportation in major cities, with large passenger flow and concentrated personnel. Once there is a fire, the consequences are very serious. Due to the unique characteristics of the subway itself, once the fire starts, it is easy to cause the spread and expansion of the fire and the generation of toxic smoke, which not only threatens the life safety of passengers, but also causes greater difficulties for evacuation and rescue work. At the same time, due to the large space in the subway, the fire alarm and automatic spray and other fire-fighting facilities are not well equipped, and once the fire starts, the underground power supply may be automatically cut off , the ventilation and air conditioning system fails and loses the function of ventilation and smoke exhaust.

After the fire is found, the alarm shall be given first, and then the nearby fire-fighting equipment shall be found to put out the fire, so as to control the initial fire within the minimum range and take all possible measures to put it out. If the initial fire fighting fails, the compartment door shall be closed in time to prevent the fire spreading and win the escape time.

When escaping, take a low position to advance (but do not crawl to avoid delaying the time of escape), do not take a deep breath, cover your mouth and nose with wet clothes or towels if possible, to prevent smoke from entering the respiratory tract; at the same time, pay attention to choose a good escape route, if there is a fire, there will be an exhaust device and air supply device in the subway, at this time, the passengers should rush to the direction of the wind To walk, that is to say, to walk against the wind. The wind, not the smoke, will help you escape.

In the process of escape, it is necessary to obey the command and guidance of the subway staff to evacuate. It is not allowed to jump blindly. The people who have escaped from the underground building shall not return to the underground again. In case the evacuation channel is blocked by fire, it is necessary to try to extend the survival time and wait for the firefighters to come to rescue.
