On the evening of July 16, Wu Jiantao, deputy chief of staff of the Jinzhou City Public Security Fire Detachment, was on duty in the detachment, and at 21:12, the command squadron of the Provincial Public Security Fire Brigade issued a notice, which was the first time to call. The Jinzhou City Public Security Fire Detachment was notified to assemble all the foam liquid on standby, saying that there was a fire in Dalian. What fire, what location, the phone didn't say.

Wu Jiantao reported the content of the notice to Wang Changchuan, the leader of the detachment. Wang Changchuan ordered: The relevant vehicles of the fire squadrons in five districts and four counties of Jinzhou City should be filled with fuel immediately, and equipment related to chemical fires, heat-insulated combat suits, video equipment, and intercom systems should be prepared. Wang Changchuan was engaged in construction review and fire prevention work in the Dalian City Public Security Fire Detachment, and the whole province reinforced Dalian, and he felt that there must have been a chemical fire.

10 minutes later, the leader of the provincial public security fire brigade called and ordered it to go directly to the head of the detachment leader Wang Changchuan, asking how many cars and how many bubbles the Jinzhou City Public Security Fire Brigade could produce, and let them set off immediately. Wang Changchuan led Li Baoquan, director of the logistics department, and Wu Jiantao, deputy chief of staff, to dispatch five fire fighting vehicles and one command communication vehicle to the highway at 22 o'clock. This is the first batch of reinforcements from the Jinzhou Public Security Fire Detachment to the Dalian fire scene. Four hours later, the Jinzhou City Public Security Fire Detachment formed a convoy of five vehicles with more than a dozen tons of foam liquid collected at the Jinzhou No. 6 Petroleum Plant and other places, and galloped to Dalian.

From Jinzhou to Dalian, it takes five or six hours to drive. The Jinzhou City Public Security Fire Detachment set off from Jinzhou at 22 o'clock and arrived at 3:40 a.m. on the 17th at Sanshilipu, near the Dalian fire ground, which took five and a half hours. It took 1 hour to pave into the fire from 30 miles, there were too many fire trucks, and the efficiency of traffic police guidance was not high. They entered the fire between about 4:40 a.m. and 4:45 a.m. On the way, the Liaoning Provincial Public Security Department and the Provincial Public Security Fire Brigade kept issuing orders, urging them to speed up and arrive as soon as possible on the premise of ensuring safety.

At 3 o'clock in the morning of the 17th, the Liaoning Provincial Public Security Department issued an order - the order was issued to the command center of the Jinzhou City Public Security Bureau, so that they could transmit the order to the fire detachment - "The second batch of reinforcements of the Jinzhou City Public Security Fire Detachment must arrive at the Dagushan fire site at 6 am on the 17th." Wang Changchuan, the head of the detachment, was stunned when he received this order, the second batch of reinforcements was mainly to transport foam liquid, and he just set off from Jinzhou at 2 o'clock in the morning on the 17th, and he would arrive at Sanlipu at 7:30 in the morning at the earliest, this situation had been reported to the headquarters, how could the superiors give such an order? Wang Changchuan was in a heavy mood and anxious, the leaders were already anxious at this time, and the situation in Dalian was bound to be extremely urgent.

At 4:45, the Jinzhou City Public Security Fire Detachment arrived at the fire scene, and Wang Changchuan, the head of the detachment, went to the headquarters to ask for instructions. The so-called headquarters is an open space, and some tables and chairs are temporarily placed, and the distribution map of the factory area is spread out on it. Wang Changchuan reported the vehicles, water volume, foam volume, and soldiers of the Jinzhou City Public Security Fire Detachment, and was given the task of putting out the fire at the pump room.

The fire ground was full of fire trucks, thick smoke, and the fire was like a river, no different from the scene of war. The officers and men were covered in oil, only their teeth and eyeballs were white, and the rest of the parts were black, and it was impossible to distinguish who was who. Wu Jiantao kept asking the officers and soldiers of each position - where is the pump room? The answer is that I don't know. He and Wang Changchuan climbed on top of a fire truck, looked around, and saw that the fire in the No. 103 tank was extremely ferocious, and most of the other parts were flowing fires on the ground, and the pipeline exploded from time to time, flashing white light. They looked for the factory, and finally found the factory, there was a row of buildings in front of the gate of the factory, the fire was blazing, Wang Changchuan estimated that it was the pump room, he ordered to drive the car over, and set up a position in the open space in front of this row of buildings.

The Jinzhou City Public Security Fire Detachment inserted the combat vehicle into the open space and faced the No. 101, No. 102, and No. 103 oil tanks. It turned out that the building in front of the vacant lot was none other than the pump room. Jin Gang, deputy head of the Dalian City Public Security Fire Brigade, is organizing officers and soldiers to extinguish the fire in the pump room. According to the command's requirements, they were assigned to the defense area of the Dalian City Public Security Fire Detachment.

Wang Changchuan ordered to hurry up and get out of the foam gun.

This is the position of the Jinzhou City Public Security Fire Detachment. They have 5 vehicles, more than 15 tons of water, more than 30 tons of foam liquid, and 4 foam tube guns. They set up ladders, and the officers and men climbed over the wall to enter the factory area.

At that time, the fire in the pump room was terrifying. Wu Jiantao asked King Kong about the fire, and King Kong said that the area was a sewage pool underground, which had been filled with crude oil, all of which were fire, and opposite was the pump house after the explosion.

Wu Jiantao ordered that Dang Wenwen, the instructor of the Linghe squadron, was responsible for supplying water to the bubbles. The Tiebei Squadron and the Guta Squadron each produced two foam tube guns. Wu Jiantao went to the Guta Squadron to command the operation, and the combat staff officer Hou Wenxu was in charge of the position of the Tiebei Squadron.

The positions of the Guta squadron were on the south side, and to the north were the pipeline complex. Some of the pipes arched from the air, and some were buried underground. The ground was full of flowing fire. Wu Jiantao empirically felt that the oil in the underground pipes burned very violently, making a whirring sound, like the sound of the wind.

The cesspool was full of crude oil, thick smoke was billowing out, and the radiant heat was so strong that people could not get close to it. The mixer truck at the site is pouring concrete one by one, approaching the sewage tank.

Wang Changchuan said that the top priority at the moment is to bring the pipeline fire under control. He led Wu Jiantao, Huang Ping, the instructor of the Guta Squadron, and Zhang Cong, the deputy squadron leader of the Tiebei Squadron, to rush to the front, from the east side of the No. 103 tank to the fire. After 40 minutes of extinguishing, the pipeline fire was basically under control.

By this time it was dawn. The officers and soldiers returned to the pump room position. The smoke in the cesspool was still too great to extinguish the fire, and the fighters dispersed the smoke with flowering foam guns, DC foam guns, but there was no effect. Wu Jiantao found cracks around the cesspool, and he asked the soldiers to plug the cracks with masonry and concrete, and poured them with water cannons. At this point, the smoke is gone, and the pump room and pipes become clear.

The soldiers are divided into two ways. Wang Changchuan led the people to fight the fire on the west side of the pump room, and Wu Jiantao and the officers and soldiers fought the fire on the owner side of the pump room. After the explosion of the pump room, the concrete beams of the windows and roof were crumbled, leaving only the sloping walls and the fire. After 80 minutes of extinguishing, the fire on both sides of the pump room was extinguished, leaving no fire. It was around 7:30 a.m.

After extinguishing the fire in the pump room, Wang Changchuan keenly noticed that the oil fire was flowing 1 meter above the ground in the southeast tank of No. 103 oil tank. At that time, people's attention was on the northwest of tank 103, where the tank exploded and tore. If the oil fire leak on the southeast side of the tank is not extinguished in time, it will affect the adjacent No. 102 oil tank. They sent deputy squadron leader Zhang Cong and soldier Zhao Long to set up positions on the protective embankment and use foam guns to intercept the ground fire that was rapidly flowing to the No. 102 oil tank. Near 9 o'clock, together with the officers and men of the Dalian detachment, they extinguished the oil fire leaking from the tank on the southeast side of the No. 103 tank and extinguished the residual fire in the pump room. By 12 o'clock, the fire extinguishing work in this area was successfully completed.

Next, the Jinzhou City Public Security Fire Detachment is responsible for cooling the No. 103 oil tank, and after their second batch of reinforcements arrived, they were responsible for extinguishing the fire on the ground of the pipeline on the north side of the water tower, with a fire extinguishing area of about 500 square meters.

From 5 o'clock in the morning to 17 o'clock in the evening on the 17th, the Jinzhou City Public Security Fire Detachment fought for 12 hours and won the victory. At 17:10, they withdrew from their positions and entered the Dalian University for Nationalities to rest.
