Chapter 119 Going Against the Fire
The old woman couldn't argue with her words and was taken away by the police officers handling the case.

Although there are many people in the bureau, things are still going on in an orderly manner, and Yu Fan's three-person team can't help much, so they discussed going back to XA by train today and resting at home for a Sunday.Guo Na booked the tickets for the three of them, and the three of them went to say goodbye to Zi Yi.

Chen Xingyang: "Brother Ziyi, we can't help here anymore, we'll go back first, and then there will be a special person to communicate with this side about the next step."

Zi Yi: "Okay, we won't keep you any longer. Even if we mobilize the surrounding police force to help, it still takes a lot of time to interrogate so many people. Let me take you to the station."

Chen Xingyang: "No, no, we can just take a taxi and go back."

Zi Yi: "It's okay, drop by. I just got the news this morning that I found the staff dormitory of their LZ branch. Those low-level people who didn't come to the meeting last night live there. My colleagues are a big I have already gone there to arrest them, and they will be completely settled after arresting those miscellaneous soldiers. They live very close to the high-speed rail station, and I happened to meet up with my colleagues after I sent you off."

Chen Xingyang said: "Okay then," and looked at his watch casually, "Actually, it's still early, we can go to their dormitory with you, and watch you clean up these miscellaneous soldiers. " After Chen Xingyang finished speaking, he looked at Yu Fan, as if he was asking for Yu Fan's opinion.

Yu Fan nodded.Then let's go.

Along the way, the car radio also broadcast: "Last night, our city police and the XA police jointly cracked a large-scale MLM case..." The sun outside the window shined on Yu Fan's triumphant face through the car window.

The MLM dormitory arrived. This building is an old rental house. When Yu Fan and the others rushed to the scene, there were already many police cars parked downstairs, and many police officers came down from the upstairs with the newly arrested people.Zi Yi went up to inquire about the situation, only to find out that this building has 5 floors in total, with two households on each floor, almost all of which are rental houses, and they are all rented to this MLM organization. 150 MLM gangs!On average, there are about 10 people in a room!
This time I was really lucky. Although it was a night, the news miraculously did not leak, and none of the people who should be arrested escaped.

Guo Na said: "It's really ironic. The trees fell and the monkeys scattered, and these people who were arrested at the conference didn't even bother to inform these people."

Chen Xingyang added: "Perhaps in their hearts they thought: 'I've been arrested, why are you guys doing it well?'"

Yu Fan said quietly: "I don't have a good life and I don't want to live as well as my own. It's a typical superior personality disorder. When I was in junior high school, once all 20 boys in my class went to an Internet cafe to surf the Internet, and the teacher came to arrest them. Originally, the teacher only arrested one student who was sitting outside, but this student even took the initiative to confess that there were 19 other students in the inner room of the Internet cafe. The whole army was wiped out. This is why it is easy to arrest corrupt officials by only catching one The reason for pulling out the entire chain of interests."

Just as several people were chatting downstairs, an urgent voice came from the police intercom: "There is a problem in room 501! The door didn't open after we knocked, and there was a fight inside!"

The conductor downstairs said calmly: "Break the door!"

As soon as the voice fell, bang!The door opens, but...

The door is opened from the inside!Three people rushed out of the room, and they fled downstairs like crazy, muttering: "Damn, this person is crazy!" The police at the door knocked down.

Another hurried voice came from the intercom: "Three people ran out of the house and were subdued, but they said that there was another person in the house who lit the gas tank! Now we can also smell a strong gas smell at the door. "

When everyone heard the news, it was like a bolt from the blue sky! ! !Everyone understands the reality that the problem is serious!
Without saying a word, Zi Yi ran upstairs in stride.Yu Fan's mind froze for a moment. He thought it was just a small matter, but he didn't expect the situation to escalate without warning.

It is not terrible to ignite the gas tank. Under normal circumstances, even if the gas tank is ignited, it will not explode. Just cover the valve with a wet towel, and then turn the valve clockwise to close it. The reason for using a wet towel is to prevent scalding your hands.Some people on the Internet say that the fire should be extinguished before closing the valve, otherwise it will backfire under negative pressure. This kind of statement is deceptive.Remember, close the valve first!Close the valve first!Close the valve first!

There are four situations that may cause a gas tank to explode.

First, the cylinder is overfilled, which is the main reason for the explosion of the cylinder.

Second, the combustion of the steel cylinder lying down is another important reason for the explosion of the steel cylinder.

Three, steel cylinders work with illness.If it is used for a long time without inspection, maintenance and repair, the steel cylinder will be corroded, perforated and cracked, so that it will lose its compressive strength, and it will easily explode when exposed to high temperature, extrusion or collision.
Fourth, some users use methods such as scalding with hot water and roasting the cylinder to make the liquefied gas burn up, which is also very dangerous! Especially burning the cylinder with fire will cause the cylinder to lose its proper strength and easily cause the cylinder to explode.

The explosion power of a household gas tank is equivalent to 150 kilograms of TNT explosives.Explosions of gas tanks often bring about two damages. The first is a physical explosion due to the rupture of the tank body. The liquid petroleum gas in the tank instantly expands 250-300 times and turns into a gaseous state, generating shock waves, just like a landmine explosion.Then, the gaseous petroleum gas is quickly mixed with the air. When its concentration in the air drops to 3%-11%, it will produce a chemical explosion and a huge shock wave when it encounters an open flame. If a person inhales this explosive gas, the respiratory tract and lung tissue will be damaged. burn out.

Before Fan Duo thought about it, Zi Yi had already run up to the fifth floor and rushed into the door of the room, only to see a gas tank lying on the door of the room, the gas tank was also surrounded by flames, blocking the door of the room like a wall of fire, People couldn't go in, and people could be vaguely seen in the corner of the house through the firewall, so Zi Yi picked up the walkie-talkie and yelled: "I saw the gas bottle, how to turn off this thing?"

Yu Fan downstairs rushed to the police officer next to him, grabbed the walkie-talkie, and shouted, "Is the bottle standing or lying down?"

"Lying down! Like a fireball!" Zi Yi shouted.

Big trouble, this is the most dangerous situation, the leaked fuel from the gas tank will be ignited, burning the bottle and the ground, and the rising temperature of the ground will heat the body of the bottle, in this case, the gas tank will be burnt 4 It will explode in minutes! ! !

Yu Fan picked up the walkie-talkie and shouted: "Run!!!!!!"

As soon as the words fell, a huge explosion sounded.

Boom! ! !
