In 2009, because the high-speed rail occupied an area, the house moved and a new house was built. I went to the hardware store to buy electrical materials, mainly wall switches and sockets. Everything was picked out and put in a bag. A stranger picked up one at random and said; "This is not a flame retardant material, and the switch contacts are open and unsafe." I asked him what he did, and he said that he was a salesman who went to this store to sell their products. The boss is unwilling to buy their products because the price is too high. I was a little tempted by what he said, so I asked the boss if he had the kind he said. The boss said yes, but the price is much higher. He said he brought me another brand of products to show me. I handed it to the shop assistant casually, and he looked at it and said; "This is no problem, don't worry." I was more careful and asked if it was their product. If they don't say anything, I will doubt it. He said; "This is not our product. Our price is a little higher than this, but this is definitely no problem. " I believed him, and spent 160 yuan more, and all of it was replaced by the product that was confirmed to be safe.
My wife and I moved in after the renovation of the new house. When I was watching TV at night, my wife asked me, what's the smell? There seems to be a gas leak, and there is a door between the kitchen and where we live. The door is closed, and everyone who comes in can smell it. The gas concentration in the kitchen can be imagined. I am reading in bed, and my wife is sitting in a chair, which is close to the door and faster than me. I immediately opened the kitchen door, turned on the kitchen light, opened the kitchen door and ran into the yard. It was too late for me to stop it loudly.
This scares me. The gas concentration is so high, never turn on the light switch on the wall. When the switch contacts are energized, an electric spark will be generated, which will ignite the mixture of gas and air, leading to a big explosion. I chased out angrily and scolded my wife severely, and he also opposed me; "I opened it, isn't it okay?" I was so angry that I couldn't laugh or cry.
Afterwards, my wife and I discussed buying an electrical appliance. electrical materials met the salesman and took his advice to buy a safety switch. I can't help feeling that this casual encounter, with only a few simple words at a time, actually avoided a major accident. Otherwise, not only our husband and wife will suffer, but also our neighbors will suffer. My kitchen is separated from my neighbor's bedroom by a wall.
Summarize; Sometimes people always ignore unusual hidden dangers, but once these things happen, the consequences are unimaginable. If I think air leakage rarely happens and buy an unqualified switch, the consequences are really unimaginable.
In the spring of 2008, I went to work in a brick factory and was responsible for supplying soil to the blank workshop, that is, driving a chain shovel to push the soil into the soil supply box and adding internal combustion to the blank, that is, coal gangue powder, which can play a role in supporting combustion when fired. One day, several carts came to the factory to deliver pulverized coal, which is the kind of dump truck called the first four and the last eight. I am responsible for driving a bulldozer to collect piles of pulverized coal unloaded from the construction site, unloading a car, and I save a car. A driver with a long-term vision stopped at the bottom of the high-voltage line and began to unload the car. Soon, the hydraulic jack pushed the car onto the high-voltage line. The driver hasn't realized that there is no spark between the tire and the ground, and there is a puff of smoke under the tire. As soon as I saw it, I quickly reminded the driver loudly, but the engine noise was too loud for the driver to hear at all. I ran to knock on the door and didn't realize it until I raised my hands. I quickly withdrew my hand, stepped back and shouted. The driver finally heard my scream, but I may not have heard what I said clearly. I opened the door and looked like I was getting off. I quickly waved and pointed to it. The driver opened the door and poked his head out. Finally, he saw that the car hit the high-voltage line and immediately got into the cab and put it down.
Think about dying. If I was so anxious that I stood on the ground and tapped the door directly, I guess I wouldn't be able to type Zhihu here now even if I didn't get an electric shock. The arc generated by 30 thousand volt high voltage electricity is enough to cripple my arm. The driver responded quickly. I didn't wave hard to get off the bus. If my feet touch the ground and my hands are on the door, the consequences will be unimaginable!
Summarize; People are prone to make mistakes in a hurry. I knew there was high voltage in the car body, but I rushed over. Fortunately, I woke up at the critical moment. Therefore, it is very important to be calm at a critical moment. We have seen people who can't swim more than once, and we have also seen reports that relatives fell into the water and went directly to save people. The result is even more tragic, so it is very important to keep calm at all times.
