The Chaoyang City Public Security Fire Detachment received an order from the command center of the Provincial Public Security Fire Brigade at 3:05 a.m. on the 17th, and the corps ordered the Chaoyang Detachment to immediately dispatch 5 foam trucks and 5 water tankers to quickly reinforce the Dalian fire.

After receiving the order, the detachment leader Li Hao's first reaction was that Chaoyang City was the farthest away from Dalian, with a driving mileage of nearly 500 kilometers. Under the premise of full load of fire extinguishing equipment and fire extinguishing agent, it is a major matter to ensure the safety of personnel and vehicles. He issued an assembly order, demanding that under the premise of ensuring safety, reach Dalian as quickly as possible.

The commander-in-chief of the detachment that day was Wang Jianguo, who was the head of the detachment's logistics department. At 3:15 a.m., Wang Jianguo mobilized the vehicles and soldiers of the Shuangta, Longcheng, and special service squadrons in the urban area to assemble at the detachment organs, and the soldiers and vehicles of the fire brigades of Lingyuan, Jianping, Kazuo, and Beipiao counties assembled at the south exit of the Jinchao Expressway. At 3:24, according to the order of the detachment leader, Wang Jianguo notified Wang Dawei, the deputy detachment leader who was leading the training of the Iron Army in Shenyang, to immediately organize 39 members of the training team to set off from Shenyang to Dalian in the detachment's troop carrier.

At 4:35, the Chaoyang City Public Security Fire Detachment embarked on a journey of thousands of miles to help, implementing 500 kilometers of long-distance cross-regional reinforcements on the highway, which is unprecedented in the history of Chaoyang firefighting. Some drivers have never driven on the highway, and the highway was repaired in many places at that time, and many sections of the road can only be driven in one direction, which is an extremely severe test for the driver of the fire truck with a large tonnage loaded with the first grade. Wang Jianguo used the walkie-talkie to call all the staff every half an hour to tell them to be safe.

At 11:03 a.m., the reinforcements of the detachment from Chaoyang and Shenyang lasted more than six hours and arrived at the assembly area, Dalian Sanshilipu, where 78 officials, 11 combat vehicles, and 3 support vehicles were all on standby.

At 11:45 a.m., they arrived at the fire. The general command of the fire field ordered: the Chaoyang detachment went deep into the first scene and was responsible for the uninterrupted water supply to the front. Wang Jianguo ordered: Section Chief Xue Yanfeng organized five water tanker trucks, 14 officers and soldiers to transport water supply and occupy fire hydrants on the ground, and the double trunk line provided uninterrupted water supply to two high-power foam trucks at Zhoushuizi Airport. Section Chief Lin Shuqiang organized 58 officers and soldiers to carry foam barrels for the fire site, distribute foam liquid, and add foam liquid to two high-power foam trucks at the airport.

During the more than three hours of coordinated operations, the officers and men of the Chaoyang Detachment successively carried 70 large barrels of foam liquid and divided 300 small barrels into 300 small barrels, totaling 7 tons of foam liquid and 300 tons of water supply, showing amazing combat effectiveness.

At 16:40, Li Hao, the leader of the detachment, rushed to the scene to command. They adjusted their force deployment, with two foam trucks and one water tanker as the main positions, and the rest of the vehicles were water supply trucks. The above-ground fire hydrant is used to lay 80 mm water hose double trunk water supply, and 65 mm water hose to supply foam liquid to ensure the supply of water source and foam liquid in front.

At 17:10, Lin Shuqiang found that the residual fire of the No. 103 tank that had been extinguished was still likely to rekindle, and decisively ordered the water cannon position to intensify the cooling, but the re-ignition speed was much faster than expected. Sun Hongming, a staff officer of the Police Training Section, led four people to lay two water hoses, used a mobile cannon to fill the tank with foam liquid, and at the same time covered all the pipes in the tank farm with foam liquid to prevent the fire from escaping the cage. At this time, a 30-centimeter-wide "red bar" appeared at the bottom of the wall of the No. 103 tank where the re-ignition occurred, which was gradually widening and brightening. Lin Shuqiang led 5 people to form the first attack group, and the squadron instructor Tian Ye led 6 people to form the first soil attack group and set up a water gun cooling position. "Pressurize, pressurize", the positions constantly shouted. The walls of the tank are red, bulging, and beating. No matter how red it is, then it drums, and then it goes on, and it goes back and forth. After 3 hours of confrontation, at 21 o'clock, the temperature of the tank was finally lowered to a safe range, avoiding the tank burning through and causing a greater disaster.

At 23:40, Li Hao, the head of the detachment, issued an order to "cool the burning tank and extinguish the fire in a timely manner", and divided three combat groups into three combat groups to take turns to extinguish the fire and cool down the battle, while resting and recuperating, while fighting, until the fire was finally extinguished.

In the 70-hour battle, the Chaoyang detachment dared to fight and rushed, and its demeanor was outstanding. After learning that the city fire detachment had successfully completed the reinforcement task, the leaders of Chaoyang City said: "Chaoyang is the farthest away from Dalian, and Lingyuan is close to 600 kilometers away from Dalian, but the Chaoyang Fire Detachment has fought continuously and has a tenacious style. ”

The Chaoyang City Public Security Fire Detachment returned to Chaoyang City at 23 o'clock on the night of the 22nd, and the Municipal Party Committee and the Municipal Government held a celebration banquet for them.
