Chapter 20 The white light of the explosion makes people unable to open their eyes
Meng Xiangbo, who was born in 1988, is the deputy squad leader of the third squad of the special service squadron of the Zhanqian Brigade of the Yingkou City Public Security Fire Detachment, and a non-commissioned officer of the first phase. He ate half a course of rice, put down the bowl, and boarded the car to Dalian.
Meng Xiangbo found that the Shenyang-Dalian Expressway was closed, and only public security fire vehicles could pass through, and the road was shining red, as if it had entered the war years.
Entering Dagu Mountain, the police car led them into the fire, otherwise no one would be able to figure out the driving route. Entering the fire, Meng Xiangbo found that it was raining in the sky, and it was only raining on the fire. He reached out and touched a handful of rain that fell on his combat uniform, and when he saw that it was black oil, it was black and shiny, and when it fell on his clothes, it rolled to the ground. He guessed that the fire had drawn a lot of water, and it evaporated into the sky under the scorching fire, and the water droplets absorbed the gaseous crude oil in the black smoke, and the mass became heavier, and it fell into rain.
Meng Xiangbo was stunned: What kind of fire is this, the water turned into oil and came down.
Although it rained darkly, the sky was red, like a huge soldering iron, and the explosions of pipes came and went.
The more their firefighting vehicles drove towards low-lying areas, more and more flowing fires gathered on the ground, and there was a great danger that the cars would drive by, and they could burst tires or roast fuel tanks. But there is no road here, and wherever there is a flow of fire, there is a road underneath.
Meng Xiangbo saw with his own eyes that a tall steel shelf had burned soft, bent down like a noodle, and lay on the ground. He was amazed that the steel frame was burned and paralyzed, what kind of fire was this?
When the car drove to the T-shaped road, the driver operated the steering wheel with one hand and blocked his face with the other - through the car glass, his face was burned unbearably, and the driver did not have a mask. The road ahead was a newly unloaded fist-sized gravel. The original asphalt road has been baked to a thin mud, and it is impossible to drive the huge fire trucks.
When Meng Xiangbo and his comrades-in-arms drove to the position, the flowing fire had already flowed to the edge of the high-risk chemical tanks. The automatic sprinkler system for the high-risk chemical tanks has been activated urgently, but the water flow is small and thin. This water is poured on the flowing fire, and it burns bigger and bigger. In the case of oil fires, only the foam liquid has the function of insulating the air and can contain some fires. Meng Xiangbo, squadron leader Lu Tianhao, non-commissioned officers Hu Yongjie and Sheng Keda operated the foam cannon together, and Meng Xiangbo set up a water hose. Their fire truck is Shanghai Graman, a northern Mercedes-Benz, and when the automatic pressurization reaches 30 to 40 pressures, the hose does not move at all. When the 80mm hose is filled with water, each one weighs 500 kilograms, and the two hoses weigh up to 1,000 kilograms. If you can't drag it, you have to drag it, Meng Xiangbo and the other four people dragged the hose over. The foam cannon spews out a white water hose and presses it against the tanks of high-risk chemicals.
It's a race against the clock against death. Although they didn't know what they were protecting, they knew that it was a chemical tank. Their shape, paint color and logo are instantly recognizable to firefighters. There is no fear at this moment, the strength of fear has passed. They were already amazed by the overwhelming fire when they first entered the fire, and now it's time for the firefighters to show their skills: fight!
Meng Xiangbo felt that his feet were unbearably hot, as if he was stepping on a red-hot steel plate. Every five or six minutes, he had to take off his combat boots and pour out the hot oil and hot water. After the water or oil flows down the clothes into the boots, it is baked by a fire flowing under the feet and a ground temperature of several hundred degrees, and the temperature rises to eighty or ninety degrees Celsius in a while. After Meng Xiangbo took off his boots, he saw that his feet were full of hot blisters, not only for him, but also for the officers and soldiers fighting on the front line.
He and squadron leader Lu Tianhao pushed the foam cannon forward. Wearing gloves is not dexterous, and as soon as I took off my gloves and touched the cannon, my hands were burned with a string of big bubbles. No one knows exactly how many degrees the temperature of the cannon, the temperature of the ground and the air is. The foam cannon pushed all the way forward to the pump room.
The fire in the pump room was as low as 20 meters high. A ton of hydrogen peroxide exploded and vaporized and burned, and the pipeline blew out a big hole, spraying a fire dragon outward, red and white. When they pushed forward, their faces were so burned that they couldn't stand it, their faces seemed to break open, and they couldn't open their eyes, so they could only rely on the water gun behind them to cool down their faces. The water gun has a strong momentum, and the water from the water gun heats up in the air, but it burns the face, like pouring boiling water. Meng Xiangbo remembered that his body was always smoking, using a water gun to draw water, smoking, and drying dry. Then draw water, smoke, and roast dry. The suit was dried in a few minutes.
How long did this state of combat last?
It's hard to believe, and the officers and soldiers themselves don't believe how they survived.
- They lasted a total of 13 hours until the early morning of the next day, without eating, drinking, or resting.
Dealing with a chemical fire accident is not the first time for Meng Xiangbo. On August 27, 2008, a chemical tanker on the side of the road in Yuantun Village, Dashiqiao City, smoked and produced a large amount of highly toxic gas, and all the villagers in this village were hospitalized. Meng Xiangbo and his comrades-in-arms wore air breathing apparatus to dilute the toxic gas with a water gun, and got on the car to remove the insulation layer to facilitate the cooling of the tanker body and prevent explosion. When chemicals react violently, the gas is hot like vapor and highly toxic. Meng Xiangbo served as the main water gunner, holding a water cannon to cool the tank less than 10 meters away from the car. I don't know if it was because of the chemical reaction of the tanker or because the water gun hit the tanker. The tanker kept making a sharp chirp, and Meng Xiangbo was the only one closest to the car to fetch water. It's hard to describe the taste, whether it's a numb scalp, or a coagulated blood, in short, the nerves are highly tense. Meng Xiangbo fought for 10 hours at the side of the tanker, from 2 a.m. to 12 noon, until the tanker was driven to the Hetao Dam to completely remove the danger. Meng Xiangbo returned to the team, took off the air respirator, and sat underground for half an hour, unable to move his whole body even if he wanted to. His eyes were black, he was deprived of oxygen, and his arms and legs seemed to have been removed.
Compared with the July 16 fire in front of him, Meng Xiangbo felt that the disposal of the chemical tanker in Waist Tun could only be regarded as a drill. The huge crude oil tank and the huge high-risk chemical tank were all soaked in the sea of fire, and not only was there a sharp whistling around Meng Xiangbo, but the explosion never stopped. What would happen if the tanks of high-risk chemicals around them exploded?
At noon on July 17, an engineer from PetroChina said: "If a group of high-risk chemical tanks explodes, its power is unimaginable to human beings, and it is even more powerful than the explosion of modern heavy weapons." ”
The foam cannon in the hands of Meng Xiangbo, Lu Tianhao, Hu Yongjie and Sheng Keda suppressed the flowing fire on the side of the high-risk chemical tank until a safety separation belt was created between the tank and the flowing fire. Then, they moved to the flange group position to cover the attack of the Shenyang City Public Security Fire Detachment.
The flange group consists of 16 pipes, which are connected to the flange. The flowing flames inside the pipe burst the flange and spewed flames outward. Hu Yongjie and Sheng Keda laid water hoses, and Meng Xiangbo and Lu Tianhao controlled the water cannons in front to suppress the fire.
"Bang-" A loud explosion rang out, and the shock wave actually wiped out the water cannon in the hands of the two of them, and the crude oil instantly flooded to the knees, and the legs became hot and unbearable. The driver, Ge Zhenchang, said that the sky was full of white light, and he had never seen such a dazzling white light, which lasted for fifteen or sixteen seconds. Meng Xiangbo said that he didn't see the white light, and his eyes couldn't be opened. He and Lu Tianhao were looking for a cannon in the oil, but the gloves were burned and sticky to their hands, so they threw off the gloves and looked for the cannon. When you can open your eyes, you can see that there is a column of water in the black thick crude oil, which is a cannon. They scooped up the cannon, straightened it, and continued to fight. They operated the cannon empty-handed, and their hands were full of hot blisters, which were crushed, mixed with foam and oil, and their palms were rotten. They kept hitting the burning pipe until dawn.
At that time, all the vehicles of the Yingkou City Public Security Fire Detachment were adding water and foam to Meng Xiangbo's main combat vehicle, and if the water cannon stopped, the Shenyang detachment attacking the team that was fighting in the ditch of the flange group would be complete. Therefore, after the water cannon in the hands of Lu Tianhao and Meng Xiangbo was shaken off by the explosion, they fought with their lives to fish out the cannon to hit the fire-breathing gap. Go and ask every firefighter, where is the life on the fire ground? Where are the chances of survival? Where is the comradeship? Where is the desperate life? They will tell you that they are on water cannons and foam guns, in the hands of comrades-in-arms, on vehicles that supply water to the rear.
Meng Xiangbo still doesn't understand, why does the white light of the explosion make people unable to open their eyes? How could a shock wave take a few tens of kilograms of water cannons out of his hands? 7.16 will never be forgotten.
In the battle of the flange group, Meng Xiangbo and Hu Yongjie put the artillery under the pipe of the flange group, and the Shenyang detachment attacked the fire above the pipeline. After a while, Meng Xiangbo and Hu Yongjie's helmets were deformed. Their artillery was fired until noon on the 17th, and they coordinated with the Shenyang detachment to clean up the fire of the flange group.
13 hours without eating, drinking, or resting, people who are on the outside feel incomprehensible, if in the battle, you know that you don't feel hungry, face to face with death, no one will feel hungry. As for thirst, the officers and men were roasted to the point of sweating and drinking water from water guns and foam. The most painful feeling is tiredness, and to put it more specifically, sleepiness. The officers and men of the Yingkou City Public Security Fire Detachment entered the fire scene from 23:30 on the 16th and fought until 16:30 on the 17th. Some of the fighters walked backwards and hit their heads on the iron poles. Hearing the order to rest, several people turned around and walked backwards, crashed into the car, on the foam bucket, not tired, but they fell asleep while walking. This kind of scene is really rare in the world. Many of the soldiers fell asleep with their lunch boxes in their hands. All of them lost seven or eight kilograms in the more than ten hours of fighting, a lot of dehydration, and everyone lost a lot of weight. On the night of July 17, the sky began to drizzle like a black shuttle, and the ground was full of oil. The officers and men could sleep but had nowhere to sleep, so they leaned on the car, hugged the car, and slept standing with an iron frame in their arms.
In the battle of 16 July, the Liaoning Provincial Public Security and Firefighting officers and men suffered how much they suffered and how many crimes they suffered could not be said for a few days and nights.
