On January 6, 2024, Chen Jianping, the actual controller of the basement floor of the building involved, leased 400 square meters of the basement floor to Wu Yong (the actual operator of the Baiyixiang Barbecue Raw Materials Wholesale Department in Yushui District, Xinyu City) for use, and the rest was idle.

Wu Yong entrusted Wu Hegen, the legal representative of the condensation refrigeration company, to build a cold storage in the form of contracted labor and materials. On January 8, 2024, Wu Hegen organized the construction personnel to start the construction, and by the evening of the 23rd, the construction of the cold storage partition wall of the double-decorated metal surface polyurethane sandwich panel, the spraying of polyurethane foam on the cold storage wall, column and ceiling, the welding of the refrigeration system pipeline and the installation of the refrigeration compressor unit, and the laying of the ground extruded plastic board.
10:06 on January 24
Wu Hegen, Song Jinlong, Deng Zhen, Yang Lu, Liu Pingping and 5 people entered the site to continue laying extruded plastic boards on the cold storage floor, and used bottled polyurethane foam caulk for caulking operations. At 13:40, 5 people went out to eat and returned to the site at 14:35 to continue construction. At 14:42, Wu Hegen left the construction site and did not return until the incident. At 14:56, Wu Yong came to the site to check the construction situation and did not leave.
3:10 p.m
The laying and caulking of the extruded board is completed.
3:20 p.m
The plastic film began to be laid on the extruded board, during which the on-site personnel heard a "popping" static sound similar to that emitted by a winter sweater.
15:22
After laying about 30 meters, the on-site personnel saw that the extruded plastic board in front of the plastic film roll was obviously bulging and accompanied by the sound of "bang", and at the same time found that there was a fire in the gap in the ground in front of the right, and the fire was unsuccessfully extinguished by stepping on it and splashing water, and then a large amount of black smoke was generated in the fire area, which quickly spread to the second floor through the stairs on the north and south sides of the first basement.

Why are there so many casualties?
The immediate cause of the accident is sobering
After investigation, it was determined that the direct cause of the accident was:
The construction of cold storage on the basement floor of Jialeyuan complex building is illegal and illegal, and the local accumulation of flammable gas is released when polyurethane foam caulk is used in construction operations to reach combustible conditions, and electrostatic discharge is generated when laying plastic film on the extruded plastic board ignites the accumulated flammable gas, which quickly ignites flammable and combustible materials such as polyurethane foam and extruded plastic board, and produces a large amount of toxic smoke;
The fire separation of the evacuation staircase shared by the first basement and the first floor is missing, and the smoke spreads quickly to the second floor;
Anti-theft nets and billboards were installed outside the game education classroom on the second floor, and the students who were being trained could not escape in time and effectively, resulting in increased casualties.
