After consulting the information, I summed up the following experiences.
First of all, if the elevator breaks down and stops suddenly, the first thing to do is to stabilize your mind, don't panic too much, and keep a clear head to solve the problem. This is what you should do psychologically. If you do this, you should take practical actions to solve the problem. We can try to press the door button continuously and ask for help through some function keys in the elevator. If possible, you can call the elevator maintenance unit for help, or you can let others hear our voice by shouting, so as to save yourself. But when saving yourself, don't pry open the door or jump from there, it will be dangerous, so be careful. Also, if the elevator suddenly drops, we can press the elevator on each floor, choose a corner, remember not to lean against the door, and then bend our knees slightly to keep balance.
The above are some basic knowledge of self-help in the case of elevator failure. If you want to know more details, you can actually search online. You must take the elevator in a civilized way and don't make some rude behaviors.
At the same time, in order to prevent elevator accidents, the property should also carry out regular maintenance on the elevator in time to avoid personal injury.
