What accidents can occur in the subway?
Subway accidents occur frequently, which has aroused people's attention to subway safety issues. As a very popular means of transportation, some netizens may have to take the subway every day to and from get off work. How much do you know about subway safety? How to save yourself if you are caught between the subway safety door and the car door? Subway emergencies: what should I do if there is a rear-end collision? What should I do if there is a power outage? What should I do if there is poison gas? How to evacuate and escape in case of danger? Let's learn about the essential common sense of subway riding safety together with the editor of the National Standard Product Network.
Being caught between the subway safety door and the car door, how can I save myself?
If you have been accidentally caught between a train screen door and a train door, then:
1. Try to hold the train door, even if you let it clamp your arm or leg, and never let it close.
As long as the door is not closed tightly, the train will never start. After the system fails to lock the door three times, the driver needs to manually re-open and close the door. When the subway door is closed, there is a "click" sound, which is the sound of the door locking. Many clothes, hair, bags, etc. that are caught are because they are too narrow and do not affect the door locking, so they still operate as usual. If you use your arms and legs or a large bag to press against the door, the door cannot be closed.
2. If unfortunately the screen door and the door have been closed, then there is a pair of yellow or red handles on the inside of the screen door. You don't need a lot of effort to break the screen door, just use a normal amount of force to pull the handle outward, let the screen door open even a gap, and the train will come to an emergency stop. (When the screen door is opened, the train circuit can be directly cut off to achieve emergency stop).
If you are unfortunate enough to turn your back on the handle, you can also try to touch the handle behind you. There is at least five seconds from the time the train closes to the time it starts driving. If there is no panic, it is enough to react.
Because the subway is buried deep underground, the environment is closed, the personnel are dense, complex and mobile, and its ventilation and smoke exhaust and personnel evacuation are greatly restricted. Once accidents and emergencies occur, not only will it cause casualties and huge economic losses, but more seriously, it will have a great impact on political and social stability. Therefore, it is necessary to inform the public what to do when encountering various emergencies when riding the subway, and how to ensure the safety of themselves and others.
Metro has fast running speed, punctuality and stability, but also brings inevitable safety hazards because of its unique operating characteristics.
First of all, the subway operates in a sealed space underground, and the ventilation effect is relatively poor. Once something happens, evacuation is inevitably restricted. If something happens after the subway vehicle enters the station, evacuation is relatively easy. If it happens in the subway tunnel, the consequences are unimaginable.
Secondly, subway trains generally carry a large number of passengers and are a highly crowded public place. Moreover, the origin of subway passengers is very complicated. At the same time, the characteristics of the subway as a large-capacity and fast public transportation in the city determine that it cannot conduct safety searches on passengers in advance and in detail like trains and planes. Therefore, its safety hazards are higher than trains and planes.
In addition, another problem that prompts the safety hazard of the subway is that the excessive flow of people makes it easy to spread respiratory diseases on a large scale. Because the subway cars are relatively blocked, the air flow is restricted, and the lack of sunlight and traffic counting make the subway a susceptible area for infectious diseases. Research literature released by the World Health Organization (WHO) and the US Environmental Protection Agency points out that the level of indoor air pollution is generally much higher than that of outdoor pollution, usually 2 to 5 times, and in extreme cases, it can exceed 100 times. As a more blocked subway station and subway car, the seriousness of air pollution is self-evident.
