As we all know, we can see a lot of subway buttons on the subway, every subway car door has. We can also see the subway button on the pillar of the waiting platform. Many people who press the emergency button can not easily say that they do not need to press the emergency button. Why does this happen?
1. Emergency stop button:
It is located on the pillar of the waiting platform, usually at both ends of the station. With text warning: non emergency use will bear legal responsibility. Pressing this button will cut off the 'signal' in the platform area and the train will stop automatically. If the train happens to be on the platform, it will not be able to start temporarily; if the train enters the 'signal' radiation range from the tunnel, it will also stop automatically.
This button is generally not recommended for passengers to use without authorization. There are Metro staff on the waiting platform. In case of emergency, please inform the staff to operate professionally. Line 1 uses a small red box, line 2 uses a small red box.
2. Emergency devices:
It is located in the train compartment, and it is usually on the side of each train door. Stick a seal, indicating: use in non emergency state will bear legal responsibility. If passengers want to open it, they must tear off the seal (red), open the cover, and then press the direction key to rotate to realize the operation, just like starting the emergency brake to stop the train.
3. Emergency call:
It is also located in the train compartment. Generally, there are four help phones in one compartment, which are also located on the side of the train door, with obvious signs (yellow), which are easy for passengers to find.
How to define a state of emergency?
When passengers' personal safety is in danger and emergency treatment is necessary, it can be judged as' emergency state '.
For example, if a passenger on the train is sick or fainting, emergency devices cannot be used. Because the travel time between stations is very short, generally two minutes a station. If the emergency unlocking device is used, the subway stops in the tunnel, which is not conducive to saving people, and may cause subsequent trains to rear end. The train driver should be informed by an emergency call. The train driver will communicate with the station affairs of the next station in advance, prepare emergency medicine and contact 120.
