After arriving at the destination, we first came to the third floor, where we introduced the knowledge of fire safety. While listening to the teacher's introduction, we took notes carefully. The teacher said, "If you find a fire, call the police directly at 1 10, and it is best to use a landline, because it is 30 seconds faster than a mobile phone." I don't understand why the landline is faster than the mobile phone. I went to the next place before I knew it.
There is an introduction on how to use a fire extinguisher. The teacher said, "when using a fire extinguisher, you should first look at the table above." If the pointer points to the green part, it can be used. " When in use, first unplug the safety bolt, then hold it in one hand and press the handle in the other, and spray it to the root of the fire source. "Some students tried it themselves.
Then, we visited the fourth floor, where we introduced the safety knowledge of household appliances. The teacher first showed us a TV video: an egg was heated in the microwave oven, and after a few seconds, it suddenly exploded; A bottle of coke is heated in the microwave oven. Slowly, the bottle began to swell and deform, and then it exploded with a bang. After reading it, the teacher also introduced some safety knowledge about the use of electrical appliances, saying, "Don't put electrical appliances in damp places, or you will get an electric shock." He also showed us a photo of a man who was electrocuted. I was shocked. It seems that we should also pay attention to the safety of electrical appliances at home! Otherwise, the consequences will be unimaginable!
Then we went to the fifth floor and visited the safety knowledge of subway escape. The teacher led us to experience a virtual subway escape. A fire broke out in a simulated subway. First pull down the emergency escape door, then open the door hard, jump out of the car and escape along the track in the opposite direction to the subway.
After the visit, we went back to school by bus. Today's visit is very meaningful, and we can learn a lot about safety. I thought to myself: life is so important, we must stay away from danger and cherish life in the future, because everyone's life is only once.
