Bi Fang ran for tens of meters in a row, leaning against a big tree with his ears blocked.
The drone flew high in the sky, and the water friends looked attentively at the sponge that was so small that it was almost invisible. Within half a minute, the yellow-brown spot suddenly became brighter.
It’s on!
The fire spread rapidly along the string, climbing up like a small snake, twisting and twisting, opening a snake kiss full of flaming teeth, and devouring it fiercely!
The loud noise made people lose their hearing for a moment. A white shock wave spread out visibly to the naked eye. The flames spurted out like an oversized welding gun. The scorching wind softened the steel and shattered the glass into pieces.
The black cement floor with a radius of several meters suddenly turned white, then cracked and deformed.
The water friends looking down from a high altitude stared wide-eyed, and their hearts skipped a beat at the sound of the explosion. They couldn't believe the scene in front of them. The cement floor should have been gray-white, but it turned black because it was soaked by rain.
Discoloration, instantly turning white...
In the dazzling firelight, the iron door twisted and was thrown into the air by the shock wave of the explosion. It rose to a height of several meters before falling again and hitting the ground hard.
Even Bifang, who was leaning against a big tree, felt a slight push on his back, which showed how strong the impact was.
The thick water mist condensed into water droplets and fell in a pattering pattern, moistening the ground again. However, before it was wetted, the remaining high temperature evaporated the water vapor dry again.
When the wind blows, it disappears.
The drone changed its angle and came to Bifang.
His brain was a little dizzy, so he was not in a hurry to appear. Instead, he took out a water bottle and drank some water to relieve the discomfort.
Water friends could only see Bifang sitting on the ground calmly drinking water, with thick smoke billowing behind him, as if everything had nothing to do with him.
Ten minutes later, after confirming that there was no secondary explosion, Bi Fang dusted off his shoulders, walked out of the tree, and looked at the thick smoke at the side door. He was not surprised.
Bi Fang took two steps forward to the door, stepped on the cracked ground and said: "Because acetylene contains a large amount of carbon, it will burn with thick smoke, and the temperature is very high. You see, the cement floor here is full of smoke."
If it turns white, it means that all the water has been evaporated. It’s really a terrible high temperature.”
Hearing Bi Fang's calm analysis, the water friends who were frightened by the power of the explosion were dumbfounded. What kind of heart can they look directly at such an explosion?
This was much more shocking than the grenade explosion in movies and TV shows. The ground turned from black to white, cracked every inch, and the iron door was carried several meters high by the shock wave, and began to deform in the air and fall to the ground.
[Scary? I don’t think it’s as scary as you]
[Fang Shen is super calm]
[Nonsense, just what we saw was several life and death crises, let alone what we didn’t see, it was so awesome, I was stunned]
[Mountain Tai collapses in front but remains unchanged, the elk moves to the left but does not blink, Fang Shen will not be Fang Shen, awesome, I am the ruthless 666 machine!]
[After all, it is acetylene, and the explosion temperature is much higher than that in ordinary bombs, right? 】
"Yes, acetylene can reach 3,600 degrees in oxygen combustion. Even in the air, it is more than 2,000 degrees, far exceeding the high temperature of ordinary bomb explosions. The melting point of iron is only 1,500 degrees. Iron Gate
If it hadn't been exploded, it might have been a puddle of molten iron by now."
"When encountering such an explosion, don't rush in because you don't know what's behind the door. It would be dangerous if there are flammable and explosive materials. Even if you are sure that there are no such things, you should be careful with the fire extinguisher."
Fire extinguisher?
Cao Lifeng, who was about to go back to the dormitory after finishing his meal, glanced at the fire extinguisher and didn't care. What should I be careful about with this thing? Isn't it just used to put out fires?
"Many people only know that fire extinguishers can put out fires, but the fire extinguisher itself is a high-pressure tank, and the internal pressure is about ten times that of the atmosphere. Under normal circumstances, a thick tank wall can effectively prevent explosions, but expired fire extinguisher tanks can cause
External pollution causes corrosion and causes it to become thinner.
In addition, the carbon dioxide flame retardant dry powder, foaming agent and other components of the fire extinguisher may also undergo chemical reactions when exposed to high temperatures, causing the pressure inside the bottle to increase. At this time, a slight bump may cause an explosion, and the power of the explosion is very terrifying.
.
In 2007, when a porter used an expired dry powder fire extinguisher in a wholesale market warehouse in Shenyue, the fire extinguisher suddenly exploded, and the porter Wang was killed on the spot.
In 2012, Mr. Lin, the owner of Shop No. 405 of Yantan Furniture Market in Lanzhou City, heard an unusual sound coming from a scrapped dry powder fire extinguisher at the door. He went over to take a look. At this time, the fire extinguisher suddenly exploded, and Lin was seriously injured.
…”
hiss!
Cao Lifeng took a breath and felt that the temperature around him had increased. He stared blankly at the fire extinguisher in the corner, quietly moved away, walked around, and went to the corridor on the other side to go upstairs.
"Well, there are many similar cases, so I won't go into details."
While he was talking, the smoke and flames at the door had dissipated. Bi Fang took out a towel, dipped it in water and covered his mouth and nose, and said in a Weng voice.
"Let's go in and have a look. Everyone should be careful before going in. Although acetylene burns to produce carbon dioxide and water vapor, there is still a lot of dust formed by the explosion, so be careful. The safest way is to cover it with a wet towel.
Cover your mouth and nose, and be careful.”
After being prepared, Bi Fang put on his backpack and came to the explosion site, which was even more terrifying.
Most of the iron box originally used as ballast was blown away, and the oilcloth inside had long been burned into black charcoal, merging with the melted iron boxes around it.
I pinched a piece of the wall and it turned into yellow ash after just a pinch.
After stepping in, the water friend's eyes were instantly attracted by a flash of red on the wall. It was a fire extinguisher, but it was far away and it didn't seem to be affected by the explosion.
But the rust on the handshake of the fire extinguisher still makes water friends who know that fire extinguishers can explode secretly frightened.
Normal days are fine, and naturally there are people responsible for inspection and maintenance. However, when the war in Yimen has been going on for a long time, lives cannot be saved, so how can anyone take care of the small fire safety?
Even Bifang carefully walked around it. The moment he avoided the fire extinguisher and entered the factory, he felt that it was all worth it.
Standing next to the fence, looking down from here, the height alone is tens of meters high. Looking at such a huge factory, a sense of ambition arises spontaneously.
The facilities inside the factory are complete, and except that there are no people around, they are almost exactly the same as usual!
It means that this place has never been raided, or the situation is critical and there is no time to move the equipment. In short, this place is undoubtedly much better than the previous factory that was emptied.
Looking at the empty factory, the water lovers were all amazed.
too big.
[Incredible, this place is too big, right?]
[The bigger the better, so the security will be stronger. Will there be anything good in the kitchen? 】
[Yes, the bigger the place, the more likely it is that there will be good things. Didn’t Lao Fang say that? 】
"It's not just the wilderness that feels vast and terrifying. It's so big here that it's scary. It's a huge abandoned factory. I estimate it's at least as big as four football fields and as tall as a cathedral.
.
The workers have left long ago, but other creatures have begun to move in. Come on, let me see what good things are here."
Bi Fang ran out along the fence and waved to the drone.
