The collapse of the building collapsed by Wu Junchong, "Safe Action" must be remembered!

Pay tribute to the hero!

Wu Junhuan, male, Han nationality, Sichuan Guangyuan, the army in December 2003, Communist Party members. He served as the second class monitor and fourth grade police chief of the Special Service Unit of the Liangfeng Road Squadron of the Weiyuan County Brigade of the Neijiang City Fire Brigade, and was temporarily responsible for the duty training and education management of the Weiyuan County Government full-time fire brigade.

After the events: at 10:19 on January 20, 2018, Weiyuan County Fire Brigade received a report that the town of Weiyuan County, Town Center Village, a group of 12 houses fire. After reviewing and inquiring, the house on fire is a single-story civil-brick-concrete structure. The affected households lived with an old couple and a son with intellectual disabilities. Inquired at the scene and found out that some of the affected households did not know whereabouts. Nearby residents suspected that the elderly were trapped in their homes. Wu Junhao immediately wore an air-breathing device and went deep into the fire for internal search and rescue.

Houses where house walls collapsed and were destroyed

Time frames at 11:20. According to team member Zhong Lin, “The captain had just entered the house and searched for a few minutes and he heard a thud.” The wall inside the house collapsed and Wu Junyan was buried.

When Wu Junhao was rescued, she was already in a coma. Subsequently, they were sent to nearby hospitals with the help of 120 medical staff. 12:50, Wu Junhuan died a heroic death.

Safe action to keep in mind!

Always remember that the preliminary estimate is the key, and the risk assessment must be completed before any harm occurs. Study and learn about neighboring buildings carefully to make solid decisions.

The safety problem caused by the collapse of the buildings: The shanty towns in the village and the suburbs are mostly three-level buildings, and individual four-level buildings. The roof and load-bearing structure of this type of fire are very flammable, the shortest 0.15 hours ( 9 minutes), up to half an hour. This is consistent with what we usually see. Basically, the half-hour arrives at the end of the day and it is gradually falling down within half an hour.

To sum up: In the fire fighting of the third-class buildings, from the point of view of enhancing operational safety, we must consider the risk that the roof may collapse within half an hour. After the roof is collapsed and the fire time reaches about three hours, we must consider the tilting of the wall. Danger.

Water gun positions are strictly prohibited to be placed in the right position of the doors and windows and above or below the light roof, sunshade, raincoat. When it is necessary to implement the demolition and interception from above, it is necessary to use fire ladders to be erected on the load-bearing walls and to protect them. The combat personnel must not leave the fire-fighting ladder (the roof operation is recommended to use a horizontal bar ladder on the roof and link with the ladder; Workers work on the horizontal bar ladder and make fixed links.

There are four precursors to the collapse of a building fire :

Analysis and Prejudgment of Collapse Law under the Effect of Building Fire

1. Hold the thermometer constantly, measure the temperature of the fire building in multiple places, and analyze the position of the building component bearing and possible collapse;

2. Look at the cracks in the building structure. After the firefighters spray water on the fire building, due to uneven heating, etc., the building components will burst and cause cracks. The fire fighters should view the gaps inside and outside the building structure on site, analyze the possible collapsed positions and do Good focus prevention and control;

3. Listen to the noise of the building. If the building has continuous bursts, reverberations and other sounds during the process of fire, judge the collapse of the building in time.

4. Examine the fire-resistance limit of the building components and comprehensively analyze the theoretical fire resistance limits of the walls, beams, floors, etc. to determine the on-site fire extinguishing combat time and evacuation time.
