At the time of the incident, the project was under construction and had not yet been put into use.
Two, the accident, emergency rescue, fire property loss statistics
(1) The course of the accident
On the morning of May 9, 2021, the construction contractor Chen Pengxin purchased a Yongheng brand 315 welding machine and arranged for Li Fuqiang, Huang Bao, Liu Yugang and Gao Weipu to work in the mezzanine above the cold storage. At about 13: 42, the worker Yuan Shicheng transported the extruded board into the cold storage and found that the ground of the east cold storage was on fire. At 13: 44, three workers working outdoors entered the cold storage with fire extinguishers, and the fire was not controlled. The surrounding surveillance video showed that from 13: 44: 09 to 13: 45: 20, a large amount of smoke was ejected from the cold storage doors in the middle and west, and the fire spread from east to west for about 5 minutes. During the period, six people ran out of the cold storage.
(2) Emergency rescue of accidents
At 13: 45 on May 9, 2021, after receiving the fire alarm, the 119 Combat Command Center of the Municipal Fire and Rescue Corps quickly dispatched the full-time headquarters of the corps and detachment, 11 fire and rescue stations, 32 fire engines and 129 officers and men to the scene for disposal, and synchronously linked the public security, emergency, garden, Jinghuan Company and other departments and units and 10 water sprinklers, and used 4 large excavators to arrive at the scene for coordinated disposal to demolish and clean up the accident site. At 14: 35, the open flame was extinguished, and the fire area was more than 3,000 square meters. After the large excavator cleaned up the scene of the accident, three people (Li Fuqiang, Huang Bao and Liu Yugang) who were buried by the building were found on the west side of the incident warehouse, and they were confirmed dead by 120 people.
(3) Statistics on fire property losses
After the fire broke out, the fire rescue agency carried out loss statistics according to the requirements of the Regulations on Fire Accident Investigation and the Statistical Method of Fire Loss. According to the declaration of the direct property loss of the parties, the direct property loss of this fire was 3,090,700 yuan.
Third, the cause and nature of the accident
The accident investigation team obtained relevant qualification documents, accident-related documentary evidence and physical evidence according to law; Fire-fighting and rescue institutions conducted an inquest on the fire scene, carried out tests, inspections and appraisals, and investigated and inquired the relevant personnel involved in the accident, found out the cause of the fire accident and identified the nature of the accident.
(A) the direct cause
Comprehensive on-site inspection, video analysis, investigation and inquiry, etc., the public security organs comprehensively ruled out the suspicion of intentional arson causing fire.
1. On-site inspection. Due to the use of large machinery to dismantle the warehouse during the search and rescue of trapped people, some evidence on the scene was lost. After on-site investigation, a burned electric welding machine, a large number of covered electrode and electric wires with fire melting marks were found on the ground in the south side of the east warehouse. The fire spread from east to west, and the burning degree at the top of the east warehouse was heavier than other parts. The fire rescue agency determined that the fire site was located on the ground in the south of Dongku.
2. Ask for information. It is understood that there is no construction plan for the cold storage reconstruction project, and Chen Peng arranged personnel to carry out the operation. Welding operations have been carried out in the mezzanine of the warehouse and the ground of the cold storage, and liquefied petroleum gas cylinders and oxygen cylinders have been stored in the warehouse. The wires and lighting iodine tungsten lamp used in the site are temporarily set by Chen Peng, and there is a switch box at the mezzanine of the warehouse.
3. Identify the test situation. Tested by the National Construction Engineering Quality Supervision and Inspection Center, the extruded board and polyurethane insulation board used in the reconstruction of cold storage did not meet the requirements of B2(E) and were flammable materials. Through the simulation test, the slag dropped by electric welding can quickly ignite the sandwich between extruded board and polyurethane thermal insulation library board. At the same time, the short circuit of wires and the long-term baking in iodine tungsten lamp also have the possibility of igniting the extruded board.
The fire rescue agency determined that the fire site of this fire accident was located at the ground in the south-central part of the cold storage on the east side of the west yard of Longhao Company; Combined with the field experiment and inspection and identification, it is determined that the fire is caused by the ignition of thermal insulation materials during construction.
(2) Indirect causes
1. Illegal operation. The construction contractor does not go through the formalities for examination and approval of hot work, and does not take corresponding fire safety measures, and uses naked fire in places with fire danger; Youliang Company subcontracts its contracted cold storage construction project to individuals who do not have the corresponding construction qualifications for cold storage projects; After Boyujie Company rented the warehouse of Longhao Company, it entrusted the cold storage project to a company without design qualification for design, and illegally built the cold storage.
2. Illegal construction and illegal rental. After leasing the land allocated by state-owned industries, the enterprises involved illegally built and rented more than 6,000 square meters of buildings without obtaining the relevant planning approval and building construction permit; The relevant government departments failed to inspect the illegal construction within their jurisdiction, lacked effective supervision over the illegal construction behavior of the enterprises involved, failed to take effective measures to stop it, and failed to investigate and deal with the problem of no construction project planning permit in the burning building in time.
3. The investigation and management of potential safety hazards is not in place. Relevant government departments failed to supervise and guide subordinate units and functional departments to perform their duties, failed to establish a ledger for hidden dangers investigation and rectification, and the situation of renting houses and subletting tenants of the enterprises involved was unclear, and no situation of rebuilding cold storage in the incident warehouse and existing fire safety hazards were found; The inspection of fire control and safety production organized by the local government is not in place.
(3) Nature of the accident
In view of the above analysis, according to the provisions of relevant national laws and regulations, the accident investigation team determined that the major fire accident was a liability accident.
Iv. Suggestions on handling the relevant responsible personnel and responsible units of the accident.

2. Ten thousand miles, the legal representative of Youliang Company, knowing that his company does not have the construction qualification to rebuild the cold storage, still contracted to rebuild the cold storage project; Failing to report the construction to the relevant departments, failing to review the qualifications of workers, failing to report the certificate of hot work, and failing to equip security officers; The Tongzhou District People’s Procuratorate approved the arrest on June 17, 2021 for failing to conduct systematic safety training, signing labor contracts and safety production responsibility letters, violating the Code for Design of Cold Stores, Safety Regulations for Cold Stores, Regulations on Fire Safety Management of Government Organizations, Enterprises and Institutions and the People’s Republic of China (PRC) Fire Protection Law, and being directly responsible for the accident.
3. Chen Peng, the person in charge of on-site construction, failed to give safety education to the workers and signed a safety agreement; Knowing that there were potential safety hazards in the construction site, Tongzhou District People’s Procuratorate approved the arrest on June 17, 2021 for failing to rectify and set up safety supervisors, violating the relevant provisions of People’s Republic of China (PRC) Fire Protection Law and Welding and Cutting Safety, and being directly responsible for the accident.

V. Suggestions on accident rectification and preventive measures
The accident investigation team put forward the following rectification measures and suggestions for the problems exposed by the accident:
(a) strictly implement the main responsibility of enterprises. Longhao Company and Tongzhou Aquaculture Farm should strictly abide by the laws, regulations and standards related to fire safety management, implement "one warehouse and one policy" refined management for existing factories and warehouses, and implement post responsibilities and fire safety management systems; To strengthen the fire safety protection and inspection of key parts, equipped with necessary fire-fighting facilities and fire-fighting equipment, to ensure the fire safety of warehouses, workshops, office buildings and other places; It is necessary to strengthen fire education and training, strengthen the examination and approval and management of hot work, and enhance the fire safety awareness and emergency response ability of employees. At the same time, it is necessary to do a good job in various safety management during the demolition of illegal construction to prevent all kinds of safety accidents.
(two) comprehensive investigation and management of fire safety hazards. All relevant departments, governments at all levels and units should carry out special actions on fire safety law enforcement inspection of warehouses, focusing on rectifying illegal operations, illegal construction, illegal hot work and welding; It is necessary to guide enterprises and institutions to self-examine and correct hidden dangers around them. For those who cannot rectify themselves, organize full-time and part-time forces to carry out investigation and inspection, sort out problems, establish ledgers, clarify rectification responsibilities, measures and time limits, carry out multi-departmental joint law enforcement and comprehensive rectification, and strengthen publicity, education and training, regularly track and review hidden dangers of write-offs, and prevent problems from rebounding and hidden dangers from resurfacing. For the hidden dangers that are difficult to rectify at the moment, it is necessary to implement targeted management and nursing measures, supervise and supervise, and promote rectification.
(three) to crack down on illegal construction and illegal rental behavior. Tongzhou district government should vigorously develop the industrial format that conforms to the positioning of Beijing’s sub-center, and actively promote the work of resolving and rectifying and promoting promotion; It is necessary to urge the local township governments to intensify the verification and disposal of houses that have not been approved for construction, identify and investigate them according to laws and regulations, and complete the demolition of unlicensed houses in stages and batches by means of self-demolition, whistle-blowing and joint law enforcement. All districts and units in the city should intensify the crackdown on illegal construction and illegal renting of factories and warehouses, and establish a long-term mechanism and regional cooperation and cooperation mechanism to prevent factories and warehouses that do not have formalities and safety conditions from being rented and subletted repeatedly.
