An explosion occurred in Beijing Haidian Hotel. What was the cause of the explosion?

The cause of the restaurant explosion was suspected to be the explosion of a gas tank, which injured three people in the restaurant. Now the explosion is under detailed investigation. My heart will tremble when I hear the word explosion. This is really a very dangerous thing. It's a minor injury, not a serious one. Especially in the catering industry, gas tanks are used for cooking. Because of the strong firepower of gas tanks, the fried dishes are delicious and the cooking speed is fast, which is useful in almost every restaurant. Some restaurants use gas tanks with a height of more than one person, but the restaurant staff have common sense about the safe use of gas tanks. Or is it safe to use a gas tank? These problems are only known to the parties concerned, but they are definitely not trivial matters. What happens is a major event.

What happened when the explosion happened? Residents nearby said that he was about five or six meters away from the hotel when the explosion occurred, and suddenly he heard a loud noise behind him. Then he felt a heat wave coming from his back. He looked back and saw that the hotel behind him had exploded and the back wall of the hotel had collapsed. Recalling the scene at that time, the gentleman still felt very scared. The restaurant where the explosion occurred was in the middle of two residential buildings, and the distance between the two residential buildings was no more than 50 meters. After the incident, we saw the kitchen pull out four tall gas tanks. There were three people sitting on the steps of the hotel, their faces were covered with blood, and emergency personnel came to treat the wound.

After the explosion, it was a mess. After the accident, a warning line was set up around the restaurant. You can see that the restaurant is in a mess and the ground is covered with broken glass. Someone tried to take a picture, but was stopped by a nearby security guard. Residents nearby said that it was only a matter of time before something happened in this store. They often see many gas tanks coming in and out of this hotel. The hotel has been open for about seven or eight years, but natural gas has not been opened, so gas tanks have been used. As for the problem that hotels are close to residential buildings, they often report to relevant departments, but there is no effective solution at present.

So what are the causes of gas tank explosion? Everyone knows that gas tanks are flammable and explosive. Sometimes high temperature may explode for a long time, and a small amount of gas will be emitted into the air when the gas is turned on. Then if there is an open flame at this time, it will cause the gas tank to explode. Also, if the gas tank has been hit or pressed violently, the pressure inside the gas tank will increase, which is beyond the pressure that the gas tank can bear, and it is easy to explode. Therefore, if we use gas tanks, we must know safety knowledge to reduce the risk of gas tank explosion.
