Top ten typical cases of national production safety accidents in 2021
1. Shandong Wucailong Investment Co., Ltd. Qixia City Wat Mountain Gold Mine "1·10" major explosion accident
At about 13:13 on January 10, 2021, an explosion accident occurred at the Wat Mountain Gold Mine in Qixia City, Shandong Wucailong Investment Co., Ltd., causing 11 deaths and direct economic losses of 68.4733 million yuan. The reason for the occurrence was that the Wat Shan Gold Mine illegally stored explosives and detonators underground, and the high-temperature slag blocks generated by the implementation of the tank cage gas cutting operation at the wellhead fell into the return air well, collided with the wellbore facilities, and fell onto the explosive packaging cartons that were randomly stacked in the middle section of the Horse Head Gate, causing the combustion of combustible materials such as cartons, resulting in detonators, detonators and explosives exploding. Main lessons: First, illegal underground mixed storage of explosives and detonators. Shandong Wucailong Company has long purchased civil explosives in violation of regulations, set up explosives storage sites underground in violation of regulations, and mixed explosives, detonators and flammable materials. The second is to carry out gas welding and cutting operations in violation of regulations. When the gas welding and cutting operation is carried out, the working environment and surrounding safety conditions are not confirmed, and the wellbore lifting and wellhead welding violations are operated at the same time. Third, the safety management is chaotic. Wat Shan Gold Mine lacks management of the construction situation of the construction unit, especially the storage, collection, handling and blasting operation of civil explosives, and the outsourced construction team is managed by a package, only the package is ignored, and the production safety accident is not reported in accordance with the regulations; the construction unit is not equipped with full-time safety management personnel and technical personnel in accordance with the regulations, and the operators use forged special operation certificates; there is no project supervision at the underground operation site on the day of the accident. Fourth, local party committees and governments are ineffective in performing their leadership responsibilities for safe production. Failure to conscientiously urge relevant departments to perform duties related to the supervision and management of civil explosives and non-coal mine safety production in accordance with the law, the Qixia Municipal Party Committee and Government reported the accident late. The regulatory responsibilities of relevant local departments have not been effectively implemented.
2. Heilongjiang Karenda Technology Co., Ltd. "4·21" large poisoning suffocation accident
At 13:43 on April 21, 2021, Heilongjiang Karenda Technology Co., Ltd. in Anda City, Suihua City, Heilongjiang Province, suffered a poisoning and suffocation accident during the shutdown and maintenance of the gas kettle in the third workshop, resulting in 4 deaths, 9 people poisoned and injured, and direct economic losses of 8.73 million yuan. The reason for the occurrence is that during the 4-month shutdown period, the gaseous materials in the gas tank were not withdrawn, isolated and replaced, and a high concentration of carbon sulfide and hydrogen sulfide gases were gathered at the bottom of the kettle, and the maintenance operators entered the bottom of the gas tank without taking any protective measures, inhaling toxic gases and causing poisoning and suffocation. During the rescue process, rescuers repeatedly probed, shouted, and dragged the kettle to rescue without taking protective measures, resulting in 9 people at the scene being poisoned and injured to varying degrees. Main lessons: First, the legal awareness of the enterprises involved is lacking and the security awareness is weak. Failure to implement the main responsibility for safe production, illegal organization of restricted space operations, and pre-operation operators did not apply for restricted space operation tickets. Second, the identification of security risks and the investigation and management of hidden dangers are not in place. Kelenda Company did not carry out self-inspection and self-inspection in accordance with the requirements of the regulations, did not identify the risk of asphyxiation in the three workshops of the gas reactor maintenance, and did not formulate reliable preventive measures. Third, the safety management is chaotic. Karenda Company did not set up a person in charge of safety production in accordance with the regulations, the safety management system was not perfect, and a safety risk control system was not established. Fourth, the enterprises involved are not in place to train the operators on the job, and the emergency response capacity is seriously insufficient. Emergency plan training and drills were not organized, and the operation site was not equipped with sufficient emergency relief materials and personal protective equipment. Fifth, local party committees and governments have not made overall plans for the relationship between development and security. The concept of safe development is not firm, the awareness of red lines is not strong, the entry threshold for chemical projects is low and the control is not strict, and in the case of weak safety foundation and insufficient safety risk management and control capabilities, blindly undertake high-risk chemical projects transferred from other places.
3. Hubei Shiyan Yanhu Community Bazaar "6.13" major gas explosion accident
At about 6:42 on June 13, 2021, a gas explosion accident occurred at the Yanhu Community Bazaar in Zhangwan District, Shiyan City, Hubei Province, causing 26 deaths, 138 injuries, including 37 serious injuries, and direct economic losses of about 53.9541 million yuan. The reason for the occurrence is that the natural gas medium pressure steel pipe is severely corroded and ruptured, the leaked natural gas is gathered in the closed space in the river channel below the accident-related building in the bazaar, and the spark discharged from the exhaust fume pipe of the catering business explodes. Main lessons: First, the investigation and rectification of potential safety hazards is not in-depth or thorough. During the renovation of the gas pipeline involved, the pipeline was illegally passed under the building involved in the accident in the bazaar, forming a major accident hidden danger. Shiyan Dongfeng Zhongxin Combustion Company has not carried out patrols in the relatively dangerous areas under the river below the bazaar for 5 consecutive years. The competent department of gas in Shiyan City has carried out many special rectifications, but no major hidden dangers have been found and eliminated. Second, the ability to respond to emergencies is insufficient. From the mass alarm to the explosion for up to 1 hour, Shiyan Dongfeng Zhongclam Company and its on-site inspection office sudden personnel failed to evacuate the masses in time, did not set up a vigilance according to the plan, prohibited the fire source, evacuated the crowd, did not immediately control the gas valves at both ends of the pipeline upstream and downstream, maintained the positive pressure in the pipeline, and put forward the wrong suggestions for ending disposal and evacuating the scene to the relevant rescue personnel without eliminating the risk of combustion and explosion. Third, the main responsibility of the enterprise involved is seriously lacking. Shiyan Dongfeng Combustion Company turned a blind eye to systematic hidden dangers such as 130 gas leakage alarms and pipeline pressure sensors being in a faulty state for a long time; appointed personnel who have not obtained the qualification assessment certificate to be in charge of safe production work; appointed personnel who have never participated in business training, do not understand the responsibilities of line inspection, and will not use gas leak detectors as the leaders of the line inspection team. Fourth, security law enforcement inspections are mere formalities. The gas management department inspected the law enforcement of gas enterprises 121 times, but did not impose an administrative penalty on illegal acts.
4. Sichuan Yifeng Food Co., Ltd. "6·13" large poisoning and suffocation accident
At about 10:30 on June 13, 2021, a limited space poisoning and suffocation accident occurred at the sewage treatment station of Sichuan Yifeng Food Co., Ltd. in Dayi County, Chengdu, Sichuan Province, resulting in 6 deaths and direct economic losses of 5.42 million yuan. The reason for the occurrence is that when the operators are ready to pump sewage sludge and slurry in the temporary storage tank, they do not take any safety protection measures, the toxic and harmful gases such as hydrogen sulfide in the pool escape and accumulate, the operator inhales toxic and harmful gases such as hydrogen sulfide, causing poisoning and suffocation, and the blind rescue of rescue personnel leads to the expansion of the accident. Main lessons: First, the implementation of laws, regulations and rules and regulations related to safe production by the enterprises involved is not in place, the new reform and expansion projects are not approved and built first, and the "three simultaneous" safety facilities of the construction projects have not been implemented. Second, the safety management of limited space operations is lacking, Yifeng Food Company has not established a limited space management ledger, has not implemented the limited space operation ticket approval system and the limited space operation "first ventilation, then testing, and then operation" requirements, has not carried out risk identification and safety condition confirmation before limited space operations, has not carried out corresponding safety production, emergency rescue education and training and safety risk tips for personnel entering limited space operations, and has not been lacking in safety management, improper emergency handling, and blind rescue of employees. Third, the implementation of the responsibility of party and government leading cadres for safe production, territorial supervision and the "three musts" requirements of local governments is not in place, the functions and strength of safety production supervision in some industry departments are weakened, safety inspections are only formalities, and the illegal construction problems of Yifeng Food Company have not been discovered in time.
5. Henan Shangqiu Zhenxing Wuguan "6·25" major fire accident
On June 25, 2021, a fire accident occurred in The Zhenxing Wuguan in Zhecheng County, Shangqiu City, Henan Province, killing 18 people, injuring 11 people, and direct economic losses of 21.537 million yuan. The reason for the occurrence is that the use of mosquito coils in the lower room of the attic on the north side of the first floor of the frontage house of the Zhenxing Wuguan accidentally ignites combustible materials such as cartons and clothes. Main lessons: First, the main responsibility of fire safety is not implemented. Zhenxing Wuguan does not have a fire safety management system, operators and management personnel have a weak awareness of fire safety, the fire hazards pointed out by the relevant departments and units have not been rectified, and fire extinguishing and emergency evacuation drills and fire inspection inspections have not been organized. Second, color steel plates exacerbate fire hazards. The first floor of the fire room is made of polystyrene sandwich color steel plate partition, after the fire quickly broke through the spread, a large number of high temperature toxic smoke poured into the second floor dormitory area, resulting in the rapid spread of fire and death. The third is the two-in-one operation of illegal accommodation. In the absence of fire safety conditions, the Zhenxing Wuguan set up a student dormitory on the second floor of the frontage room, and illegally concentrated on the students, because there was no physical separation, and there was only one open inner staircase, and the smoke spread rapidly through the stairs. The fourth is to set up anti-theft windows in violation of regulations. Anti-theft windows were set up on the east side windows of the second floor of the fire building, and after the stairs were blocked by smoke and flames, the people in the room could not escape through the windows. Fifth, the implementation of local government fire safety responsibilities is not in place. Inadequate supervision of off-campus training institutions, found that unlicensed schools have not taken measures to ban according to law, illegal off-campus training activities have existed for a long time; failure to conscientiously perform fire supervision and inspection duties, failure to timely discover and correct serious safety hazards such as the illegal use of color steel plates and the installation of anti-theft nets, and falsification of inspection records; failure to establish grass-roots fire safety organizations, grid management is in the form of formalities, and guidance for mass fire control work is not in place.
6. Jiangsu Suzhou Four Seasons Open Source Hotel "7.12" major collapse accident
At about 15:31 on July 12, 2021, a collapse accident occurred in the auxiliary room of the Four Seasons Open Source Hotel in Wujiang District, Suzhou City, Jiangsu Province, resulting in 17 deaths and 5 injuries, and direct economic losses of about 26.15 million yuan. The reason for the occurrence is that the construction personnel blindly demolished all the load-bearing horizontal walls and most of the inner longitudinal walls of the six bays on the ground floor without any reinforcement and safety measures, resulting in the interruption of the power transmission path of the superstructure, and the two-story surface circle beam was not enough to withstand the load from the upper two- and third-floor walls and the second-floor surface, resulting in the continuous collapse of the auxiliary room from bottom to top. Main lessons: First, the owner of the house did not fulfill the obligation of the person responsible for the safety of the use of the house, and contracted the decoration and decoration project design and construction business on the first floor of the accident building to a construction company without corresponding qualifications; the construction drawing design documents were not sent for review; and the construction start was organized without authorization without a construction permit, changing the main body and load-bearing structure of the building of the business premises. Second, the construction unit contracted the accident building decoration and renovation project without obtaining the corresponding qualifications in accordance with the law, and subcontracted the demolition business to individuals who did not have the corresponding qualifications; did not prepare a special construction plan for the safety of the wall demolition project, and did not have the corresponding review procedures; and did not make a written safety submission to the construction workers and signed and confirmed. Third, the designer did not obtain the designer's qualification, and without a true understanding of the structural form of the auxiliary house, provided the wrong wall demolition drawings, and incorrectly guided the demolition of the load-bearing wall. Fourth, there are loopholes in the supervision and management of existing building reconstruction and decoration projects without approval, illegal contract issuance, and so on.
7. Guangdong Zhuhai Xingye Express (South Section) a bid section of the Shijingshan Tunnel "7·15" major water permeability accident
At 3:30 on July 15, 2021, during the construction of the right line of the Shijingshan Tunnel of the Xingye Express Line in Xiangzhou District, Zhuhai City, Guangdong Province, the palm face vault collapsed, inducing a water permeability accident, resulting in 14 deaths and direct economic losses of 36.78677 million yuan. The reason for the occurrence is that when the tunnel passed through the Jida Reservoir, it encountered a water-rich granite weathering deep trough, and in the case of not discovering the geological conditions of the incident area, not advanced geological drilling, and not advanced grouting and reinforcement, it improperly used the mining method step method to excavate and excavate, the small catheter advanced support measures were reinforced and the excavation was too large, resulting in the collapse of the palm face vault of the right line tunnel and permeability. Muddy water poured into the left-line tunnel through the cross-lane passage, causing the left-line tunnel operators to drown. The main lessons: First, the risk awareness of tunnel construction under complex geological conditions is poor, and the construction unit does not carry out dynamic monitoring of water inrush during the tunnel excavation construction process; it does not grasp the advanced geological drilling and exploration situation before the excavation of the water-rich section; it does not adjust the construction method in time according to the advanced geological forecast prompts, and the excavation method, advanced support measures and excavation scale do not meet the relevant specifications and design requirements; the linkage alarm system is not equipped according to the requirements of the specification, resulting in the inability to notify the relevant personnel to evacuate in time after permeability. Second, the supervision unit did not strictly supervise the side stations in accordance with the construction control points and process requirements, and did not perform its duties on the post according to the regulations; the construction unit did not adjust the construction method according to the design requirements, expand the excavation and other safety hazards and did not supervise and rectify in time. Third, the construction unit did not provide the construction unit with accurate and complete geological conditions in the area where the incident occurred, did not add advanced geological drilling projects according to regulations during the construction period, did not coordinate with the water administrative department on the release of water from the reservoir, and did not obtain a water administrative permit to carry out construction within the scope of water conservancy project management and protection. Fourth, the regulatory authorities are not meticulous enough in the safety supervision of key projects, dangerous projects, and key links, have insufficient understanding of the particularity of the construction of tunnels through the lower reservoirs, and lack targeted regulatory measures.
8. Jilin Changchun Li's Wedding Dream City "7·24" major fire accident
At about 15:40 on July 24, 2021, a fire accident occurred in Li's Wedding Dream City, Jingyue High-tech Industrial Development Zone, Changchun City, Jilin Province, causing 15 deaths and 25 injuries, an area of 6200m2, and a direct economic loss of more than 37 million yuan. The reason for the occurrence is that the upper lighting line of the "wedding scene" studio on the second floor of Lee's Wedding Dress Dream City leaked electricity, breaking through its threaded snakeskin metal pipe and igniting the surrounding combustible simulated plant decoration materials. Main lessons: First, illegal construction. Li's Wedding Dream City changed the industrial plant to commercial use and expansion without authorization, illegally built an outdoor color steel plate house and closed the passage of fire trucks; illegally used combustible insulation materials, failed to set up safety exits, evacuation passages, fire partitions, indoor fire hydrants and smoke exhaust facilities in accordance with the law; did not lay electrical lines and set up power distribution systems in accordance with national technical standards. The second is the illegal design and construction. The relevant units are not qualified for design and construction, and do not design evacuation channels, fire partitions, fire resistance limits of building components and combustion performance of decoration materials according to the specifications, etc., in violation of mandatory standards for fire safety; the construction party enters the construction site knowing that The Li's Wedding Dream City has not handled fire protection procedures in accordance with the law and does not have fire safety conditions, there is no electrical design drawing, and the electrical construction does not meet the specifications; the thermal insulation project illegally uses polyurethane foam as an insulation material, and does not do fire treatment, causing the fire to spread rapidly after the fire occurs. Third, there is a serious lack of safety management. Li's Wedding Dream City has not established a safety production responsibility system, has not formulated a safety production management system, operating procedures and accident emergency rescue plans, has not set up a safety production management agency, equipped with full-time safety management personnel, and has not carried out fire inspection and hidden danger investigation. Fourth, local government departments are not in place to perform their duties. Only supervise and inspect the permitted construction projects, and overlook and miss the long-standing illegal reform and expansion of Li's Wedding Dress Dream City; carry out the "two violations" inventory operation is not thorough, no hidden dangers of the Li's Wedding Dress Dream City problem are found, and there are deficiencies in investigation and rectification; there is a single law enforcement in fire supervision and inspection, there is no follow-up problem hidden danger rectification, missed rectification matters, and law enforcement does not close the loop.
9. "7.26" major road traffic accident in pingliang section of Qinglan Expressway in Gansu Province
At 14:05 on July 26, 2021, a road traffic accident occurred in the Pingliangjingchuan section of the G22 Qinglan Expressway in Gansu Province, where a large bus ran out of control and overturned the road, causing 13 deaths, 44 injuries, and direct economic losses of more than 21 million yuan. The reason for the occurrence is that the driver of the accident bus did not maintain a safe driving speed on rainy days, and the bus with poor driving technology and overloaded luggage compartment improperly handled emergency operation at high speed, resulting in the vehicle rolling out of control. Main lessons: First, the source of vehicle testing and inspection is a prominent problem of fraud. Between 2016 and 2021, the relevant vehicle testing and inspection enterprises conducted multiple bus type reviews of the accident vehicles, all of which had data fraud problems, and the "Classification and Classification of Operating Bus Types (Review Form)" issued by the company was seriously inaccurate. Second, the main responsibility of transport enterprises for safe production is seriously not implemented. The safety production management institution of the enterprise to which the accident vehicle belongs is useless, the main person in charge is absent from the enterprise for a long time, only charges and does not manage the contracted vehicle, and the safety education and training of the driver and the employee is in the form; and the accident vehicle contractor uses false driving permits, seriously inaccurate test reports and other materials to illegally obtain the vehicle's "Road Transport Certificate", fabricate false chartered car filing information to obtain tourist chartered car sign plates in violation of the law to carry out chartered passenger transport. Third, the safety supervision of relevant departments of local governments is ineffective. The transportation department does not strictly control the review of the type of passenger car, resulting in vehicles that do not meet the standards of the type of bus entering the tourist passenger transport market; the transportation and public security traffic police departments supervise and urge key transportation enterprises to carry out the investigation and governance of potential safety hazards, and there are weak links in the supervision and law enforcement of enterprises and their vehicles; the market supervision and management department has neglected to inspect and mismanage the behavior of vehicle testing and inspection enterprises for repeated data fraud.
10. Qinghai Haibei Prefecture Xihai Coal Development Co., Ltd. Chaidar Coal Mine "8.14" roof pumping led to a major accident of sand collapse and mud collapse
At 12:10 on August 14, 2021, a sand collapse accident occurred in the Chaidar Coal Mine of Xihai Coal Development Co., Ltd. in Haibei Prefecture, Qinghai Province, resulting in sand collapse and mud collapse, resulting in 20 deaths and direct economic losses of 53.9102 million yuan. The reason for the occurrence is that the top of the Qaidal Coal Mine +3690 comprehensive discharge work surface is not completely drained, the working surface has abnormal water, and many times before the comprehensive mining bracket, the local piece gang roof has occurred, and even the hydraulic support has been "crushed", the working surface has been blocked, but no effective measures have been taken to treat it, the illegal risk of dredging, the forced top lifting operation, resulting in the extraction of the top coal, a large number of top coal, slag and water mixture in the form of mud and rock flow rapidly collapsed into the working surface and the transport trough, resulting in accidents. Main lessons: First, the investigation and management of security risks are not in place. The survey and hidden danger investigation of the hidden disaster factors in the mine are not in place, and the management of the hidden dangers of accidents in the surface open pit is not thorough. The second is to organize production operations in violation of regulations. The Chaidar Coal Mine refused to carry out the supervision instructions for suspension of production and rectification, and organized mining operations in violation of laws and regulations even when the relevant licenses were temporarily withheld. Third, the safety management is chaotic. Some workers in the Chaidar Coal Mine did not sign a labor contract, did not pay the work injury insurance, did not participate in safety training and entered the well, and some workers did not carry personnel position monitoring identification cards when they entered the well. Fourth, the superior company did not conscientiously perform its safety management duties. The Xihai Coal Development Company did not resolutely stop the maintenance of the +3690 comprehensive discharge face of the Chaidar Coal Mine; the Qinghai Transportation Group neglected to control the loopholes and blind spots in safety management after the shareholding system mixed reform of the subsidiary Xihai Coal Development Company. Fifth, local governments and relevant departments are ineffective in implementing safety supervision responsibilities. The local governments of Haibei Prefecture and Gangcha County have not seriously studied and solved the problems of weakening the leadership team of the emergency management department and insufficient supervision of coal mines.
