First, accidents are unpredictable. The environment we are in now is unstable, just as the rainstorm in Zhengzhou was unexpected. In the face of natural disasters, human beings always have no choice but to do nothing. Faced with this similar phenomenon, we can only make all preparations in advance. Many times, we don't know what will happen next and what difficulties we will face. We can only protect ourselves as much as possible.
Second, public transport should be fully equipped? Trains, like transportation, are used by many people every day, so we should ensure the safety of citizens. Although the domestic subway has developed very well and no disasters have occurred, many times accidents come suddenly. Even if there are no natural disasters, there may be some man-made threats. At this time, the escape door will help. In the face of any disaster, the escape door is useful. More tools are better than nothing.
Third, nip in the bud From the public's point of view, taking transportation is a convenient way to buy and make your life faster. The subway runs underground. If there is a landslide or flood, that person will be at a loss. If an escape door is set up, the chances of escape can be increased, and people will not be trapped and cause casualties like this Zhengzhou incident.
? As a means of transportation, trains should be equipped with escape doors. Even if there is no accident, it may help. The escape door is just a guarantee. We should consider all the possibilities when designing the train, so as to reduce the risk in case of disaster. I hope that in the next disaster, there will be no mistakes like Zhengzhou, so that everyone can better rescue.
