Ten typical cases of national production safety accidents in 2020
1. "3·7" major collapse of Xinjia Hotel in Quanzhou, Fujian
At 19:14 on March 7, 2020, a building collapsed in Xinjia Hotel, Licheng District, Quanzhou City, Fujian Province, resulting in 29 deaths, 42 injuries and a direct economic loss of 57.94 million yuan.
The cause was that the accident unit converted the Xinjia Hotel building from the original four-storey illegally increased mezzanine to seven-storey, which reached the ultimate bearing capacity and was in a critical state of collapse. In addition, the illegal reinforcement and welding of the supporting steel column at the bottom layer before the incident caused the steel column Instability and damage caused the overall building to collapse.
Main lesson
One is that enterprises act recklessly in violation of laws and regulations.
The illegal owners of Xinjia Hotel did not obtain the relevant construction permits and did not organize the survey and design, and repeatedly contracted the project to unqualified construction personnel. Knowing that there are a large number of people upstairs, they violated the rules and took risks. , Which eventually led to the collapse of the building; relevant intermediary service agencies undertook business violations and even issued false reports.
Second, the concept of safety development is not strong.
Licheng District is pursuing economic development unilaterally, and has given the green light for illegal construction through the policy of "building houses under special circumstances", laying down major safety hazards; the relevant departments of Fujian Province and Quanzhou have insufficient awareness of the long-term and large number of major safety risks of illegal construction, and investigation of hidden house safety hazards Governance is only a formality.
Third, the relevant departments of the local government are seriously irresponsible in their supervision and law enforcement.
The planning, housing construction, urban management, and public security departments of Quanzhou and Licheng Districts have long turned a blind eye to violations of laws and regulations such as Xinjia Hotel’s failure to obtain construction-related permits and special industry permits for foreign operations.
Fourth, the relevant departments have failed to comply with the examination and approval checks.
Quanzhou City, Licheng District, fire control agencies, public security and other relevant departments, and Changtai Sub-district did not strictly control the material form review and on-site review, so that the projects that did not meet the requirements were confused and existed for a long time.
2. Major explosion accident of "6·13" liquefied petroleum gas transportation tanker in Wenling section of Shenhai Expressway
At about 16:41 on June 13, 2020, a major explosion of a liquefied petroleum gas tanker occurred on the off ramp of the Wenling West Exit of the Wenling Section of the Shenhai Expressway in Wenling City, Taizhou City, Zhejiang Province, causing 20 deaths and 175 people. Injuries, direct economic losses of more than 94.7 million yuan.
The reason is that when the accident vehicle was driving to a curved road section, it did not slow down in time, causing the vehicle to roll over. The front head of the tank violently collided with the end of the flyover concrete guardrail, forming a breach and quickly tore and disintegrated, leading to liquefaction The liquefied petroleum gas quickly vented, vaporized, and diffused. When it encountered sparks from passing motor vehicles, it ignited, and finally the vapor cloud exploded.
Main lesson
First, the main responsibility of the company's production safety is seriously not implemented.
Ruian Ruiyang Dangerous Goods Transportation Co., Ltd. ignored the national laws and regulations on the transportation of hazardous chemicals, and did not strictly carry out GPS dynamic monitoring, safety education management, truthful uploading of electronic road bills, etc., and there are violations such as vehicle affiliate operations. GPS monitoring platform Operating service providers violated regulations to assist companies in evading supervision.
The second is that the relevant industry associations have not truthfully carried out the level assessment work of safety production standardization.
No falsification of the company's self-assessment report, non-compliance with the regulations, etc. were found, the safety production standardization construction grade certificate was issued in violation of regulations, and the annual inspection was assessed as qualified in violation of regulations.
Third, the ramp owner, construction, and supervision units of the accidental section did not strictly perform their duties during the construction of the anti-collision fence, and the overlapped construction of the anti-collision fence did not meet the requirements of the standards, specifications and design documents.
Fourth, the concept of safety development of relevant local party committees and governments is not firmly established, and the implementation of safety leadership responsibilities is not in place.
Local government transportation, public security, highway management and other departments have loopholes in safety risk management and supervision and law enforcement in the transportation of hazardous chemicals, highway construction and maintenance, and project quality supervision.
3. Hubei Xiantao Lanhua Silicone Co., Ltd. "8·3" large flash explosion accident
At about 17:39 on August 3, 2020, an explosion occurred in the methyl tributyl ketoxime silane workshop of Xiantao Lanhua Organosilicon Co., Ltd., Xiantao City, Xiliuhe Town, Xiantao City, Hubei Province, causing 6 deaths and 4 injuries.
The reason is that the operator did not completely discharge the material at the bottom of the layerer to the extraction process when cleaning the materials in the layerer, which caused the excess methyl ethyl ketoxime hydrochloride to enter the product neutralization process and put it in 1# to stand still The tank causes the "reaction downward", and the reaction heat accumulates in the standing tank. There is no temperature monitoring and cooling measures in the standing tank, and methyl ethyl ketoxime hydrochloride decomposes and explodes.
Main lesson
First, the accidental enterprises have weak safety awareness and lack of awareness of the rule of law.
The accident workshop did not have formal design and acceptance, illegally organized production, and did not formulate the operating procedures of the layerer; the safety risk identification was not in place, and the understanding of the hazardous characteristics of methyl ethyl ketoxime hydrochloride was insufficient; the equipment, facilities, components and automatic control system were defective, The academic qualifications of the employees do not meet the requirements, and the abnormal working conditions are not handled properly.
Second, the local government has a weak awareness of the red line of safe development.
The responsibility for territorial management of safety production is not in place, the supervision and inspection of the illegal organization of production by the accident enterprise is not effective, and the work of comprehensively identifying safety risks and hidden accidents is not thorough.
4. "August 29" major collapse of Juxian Hotel in Linfen, Shanxi
At about 9:40 on August 29, 2020, a collapse occurred at the Juxian Hotel in Chenzhuang Village, Taosi Township, Xiangfen County, Linfen City, Shanxi Province, resulting in 29 deaths and 28 injuries, and a direct economic loss of 11.6435 million yuan.
The reason is that the integrity of the building structure of Juxian Hotel is poor. After many additions, the load-bearing brick columns in the northeast corner of the banquet hall have been in a state of high stress for a long time; part of the roof prefabricated slabs on the second floor of the north building have been overloaded for a long time, and the upper blast furnace Under the continuous pressure of the water slag insulation layer, brittle fracture occurred, forming a violent impact on the top of the banquet hall, causing the load-bearing brick column in the northeast corner to collapse, and finally the southern half of the second floor of the north building and the banquet hall as a whole collapsed.
Main lesson
First, the operators of Juxian Hotel illegally occupied land for a long time, repeatedly obtained unauthorized collective land construction land use certificates through improper means, and refused to implement the administrative penalties of the original Xiangfen County Land and Resources Department and the People's Court.
The second is that the operator of Juxian Hotel has performed 8 illegal expansions. It has never been professionally designed, unqualified and not constructed according to specifications, and has never been completed and accepted. It only relies on the contractor and personal ideas, and the whole construction process is unattended and unchecked. , Housing quality and safety are not guaranteed.
The third is that the operator of Juxian Hotel arbitrarily engaged in operating activities in the self-built farm house, failed to investigate and rectify the hidden dangers of construction safety, and failed to implement the main responsibility for safety production.
Fourth, the Taosi Township Government of Xiangfen County and the “two committees” of Chenzhuang Village did not earnestly perform their territorial management responsibilities, lacked control over the conversion of rural self-built houses to business activity sites, failed to comply with requirements for unauthorized reconstruction and expansion, adding floors, barbarous decoration, and illegal Focus on investigation and remediation of illegal building construction.
Fifth, the Xiangfen County Government of Linfen City and relevant departments are not strict in administrative approval and supervision and enforcement. In violation of regulations, blank collective land construction land use certificates with official seals of the government were issued to townships in advance, and expired certificates were extended in violation of regulations; In multiple rounds of cracking down on illegal land occupation and non-agricultural construction and rectification, the supervisory and law enforcement officers failed to effectively stop and investigate the hotel’s long-term violations of laws and regulations.
5. "September 6" major production safety accident of Gansu Baiyin Gansu Hongda Aluminum Profile Co., Ltd.
At about 2:22 on September 6, 2020, a cooling water flashing accident occurred in the melting and casting workshop of Gansu Hongda Aluminum Profile Co., Ltd., Baiyin District, Baiyin City, Gansu Province, causing 4 deaths and 6 injuries.
The reason is that after the workers in the melting and casting workshop found an abnormal situation in the casting process, they did not stop the operation in time when the cooling methods such as adding aluminum cake and speed regulation were not effective, which caused the aluminum alloy rod to leak and a large amount of high temperature aluminum liquid entered into the cooling In the shaft, the cooling water instantly vaporizes and a violent oxidation reaction of aluminum powder occurs. The resulting mixed gas volume expands rapidly in a relatively closed space, and the accumulated energy is suddenly released to form a shock wave, which leads to an accident.
Main lesson
First, the company's security system is not in place and the content is unscientific.
The safety training system has not been implemented, the personnel of the three positions have insufficient certificates, and the three-level safety training education is not in place; the illegal use of the 12-hour two-shift continuous work system, the lack of safety management in the casting workshop; the unreasonable work system leads to poor night shift production scheduling, Safety supervision was out of place, the shift leader found that the violations on the spot were not corrected in time, and mishandled abnormal conditions that occurred during the production process.
Second, corporate security management is not in place.
The risk level of the melting and casting workshop does not match the safety management measures, and the hidden danger investigation and management is not closed; the formulated safety operation procedures for the melting and casting workers lack specific operating procedures and steps, and the main hazardous and harmful factors of the position; the safety management organization is not set up, and the safety management responsibility boundary Clearly, the number of safety management personnel is insufficient.
The third is that the supervision department has insufficient professional strength in safety inspection and failed to discover the hidden safety hazards and existing problems in the casting process of the melting and casting workshop in time.
6. "September 18" major water traffic accident on Laotieshan waterway in Bohai Strait
At about 4:19 on September 18, 2020, a major water traffic accident involving a collision between a merchant ship and a fishing boat occurred in the Laotieshan waterway of the Bohai Strait. The fishing boat sank and all 10 fishing crew members were missing. The direct economic loss was about 3 million yuan.
The reason was that the fishing vessel violated the collision avoidance rules and the foreign merchant ship failed to sail at a safe speed. After the encounter between the two ships constituted an urgent situation, they did not take effective collision avoidance actions and eventually collided.
Main lesson
The first is that the crew of the fishing vessel has low safety awareness, insufficient safety skills, and failed to perform the duty of avoidance in the accident.
The second is that the automatic identification system of the fishing vessel cannot work normally, which makes it impossible to display the position and dynamics of the vessel on the electronic chart system of the merchant vessel.
Third, merchant ships rely excessively on autonomous driving facilities and ignore the use of other effective means of observation such as radar and vision, resulting in failure to identify and find fishing vessels in time.
Fourth, the merchant ship left the scene after the accident and failed to rescue the fishermen in distress at the first time, which increased the accident loss.
Fifth, the source supervision of the fishing port is not in place, and the effective inspection of fishing boats operating out of the port has not been implemented, resulting in the fishing boat manning that does not meet the legal requirements.
7. "September 27" major fire accident in Songzao Coal Mine of Chongqing Nengtou Yu New Energy Co., Ltd.
At 0:20 on September 27, 2020, a major fire accident occurred in the Songzao Coal Mine of Chongqing Nengtou Yu New Energy Co., Ltd., resulting in 16 deaths, 42 injuries and direct economic losses of 25.01 million yuan.
The reason was that the coal gangue accumulated under the belt of large inclination coal carrying uphill in Songzao Coal Mine, and the return roller at the 63.3-meter elevation of the fire point was stuck, worn through and formed a gap, and pulverized coal was deposited inside; severely worn belt and fire The sliding friction of the return roller generates high temperature and sparks, which ignites the accumulation of pulverized coal in the gap of the return roller; the belt conveyor operation supervisor finds the tape abnormality, and the ground control center is called to stop the tape operation. After the emergency shutdown, the static tape is drawn Burning, unqualified flame retardant performance of tape, large roadway inclination, upward ventilation, increased fire, causing mixed combustion of tape and coal; fire destroyed equipment, damaged ventilation facilities, and generated toxic and harmful high-temperature flue gas quickly spread to 2324-1 coal mining work Face, causing heavy casualties.
Main lesson
First, Songzao Coal Mine emphasizes benefits over safety.
The employees of the mine have checked out the problems and hidden dangers, such as a lot of floating coal in the No. 2 high-inclination belt roadway, serious damage and deformation of the lower roller and upper bracket, and reported to the coal mine manager and other management personnel, but the mine manager has nothing to do. The "red line" awareness, in order not to affect the normal production of the mine, did not immediately stop production, but planned to replace it during the National Day shutdown and maintenance, and required that the remediation work should not affect the belt coal transportation and allow the belt conveyor to "operate".
Second, the mine safety management is chaotic.
No. 2 large inclination coal conveyor belt to prevent the gangue from falling. The gangue shed is not maintained in time, deformed and damaged. The coal is sprinkled seriously during the belt operation. The lower part of the belt is accumulated, buried or even stuck in the lower idler. The worn-out, worn-out, and severely worn belts caused a fire by sliding friction with the stuck lower roller; the coal mine did not manage and distribute self-rescuers in a unified manner according to regulations, and some self-rescuers had insufficient pressure.
The third is that Chongqing Energy Group's supervision of coal mine safety production management responsibility is not in place, and four levels of management are implemented for the safety of its coal mines, with overlapping functions, unclear responsibilities, and weak implementation of responsibilities.
8. "10·1" major fire accident of Taichi Mountain Skating World Agriculture and Forestry Ecological Amusement Park Co., Ltd., Taiyuan, Shanxi
At 13:00 on October 1, 2020, a major fire accident occurred at the Ice Sculpture Hall in Taiqi Mountain Scenic Area, Xiaoshangou Village, Yingze District, Taiyuan City, Shanxi Province, causing 13 deaths and 15 injuries.
The reason was that after the 10kV power supply system of the scenic spot was repaired and the power supply was restored, when the scenic spot electrician switched the power supply from the self-provided generator to the mains power supply, he carried out the illegal operation of quickly pulling and closing the isolation switch with the load, which formed a formation on the lighting circuit. The impulse overvoltage breaks down the electronic components of the decorative lamps and causes a short circuit; the design and installation of the lighting electrical circuit in the train passage are not standardized, and the large-capacity air switch with no leakage protection function can not trip in time after the short circuit occurs. The fault is removed, and the continuous short circuit current It caused the electronic component device to catch fire, ignite the circuit insulation layer and the polyurethane insulation material, and then ignite the polystyrene foam sandwich panel partition wall and the polyurethane insulation material in the ice sculpture hall.
Main lesson
One is that enterprises ignore national laws, regulations and policies, and carry out illegal land occupation and illegal construction activities for a long time without obtaining administrative approval procedures from relevant departments.
Second, the company did not use formal design, construction, supervision, and acceptance units in the construction of amusement parks, resulting in electrical wiring, ground short-circuit protection, escape routes, and safety exits that did not meet safety requirements, and even artificially blocked ice sculptures. Museum safety exit.
The third is the use of flammable and combustible insulation materials such as polyurethane and polystyrene in crowded places in violation of regulations.
Fourth, the person in charge of the company has a weak safety awareness, has not established a safety production management organization, is equipped with full-time and part-time safety management personnel, and has improved the full-time safety production responsibility system. The investigation, rectification, and rectification of potential safety hazards go through the scene, and safety management is just a formality.
Fifth, the local government has not correctly handled the relationship between safety and development, and the safety supervision responsibilities of relevant departments have not been implemented.
9. "11·29" major flooding accident at Yuanjiangshan Coal Mine in Hengyang, Hunan
At 11:30 on November 29, 2020, a major flooding accident occurred in the Yuanjiangshan Coal Mine of Daozi Coal Industry Co., Ltd., Leiyang City, Hengyang City, Hunan Province, causing 5 deaths and 8 loss of connection, and a direct economic loss of 34,840,300 yuan.
The reason is that Yuanjiangshan Coal Mine has ultra-deep and cross-boundary mining steeply inclined coal seams at -500m level 61 coal-uphill roadway mining. Under the combined action of mine pressure and upper water pressure, drainage occurred, leading to the upper Daozi No. 2 mine from -350m to- Water accumulated in the 410m goaf, and a large amount of old goaf water quickly collapsed into the Yuanjiangshan Coal Mine's -500m level, and quickly rose to stabilize to -465m, causing the mine tunnel to be flooded and causing heavy casualties.
Main lesson
First, Yuanjiangshan coal mines have long been crossing the boundary at ultra-deep and illegally mining national resources.
The mine had cross-border mining before 2011, and the ultra-deep cross-border to -500m level at the end of 2019; evaded it by tampering with the real elevation of the roadway, not marking it on the drawing, setting up movable iron gates underground, and not installing monitoring systems and personnel positioning systems. Safety supervision, long-term illegal exploitation of national resources.
Second, Yuanjiangshan Coal Mine illegally organized production.
During the cancellation of the safety production license, the local government issued the stop production instruction, and the technical transformation, the mine arbitrarily dismantled the hoisting winch and the entry rail seal, cut off the main shaft video monitoring power supply, stopped day and night, and produced 5.56 coal in 2020 alone. Million tons.
The third is that Yuanjiangshan Coal Mine uses processes that are expressly prohibited by the state and is managed by contract, resulting in chaotic production organization.
The mine uses roadway coal mining, pit wood support, chaotic mining layout, multi-head operation, unsound ventilation system, and no 2 safety exits. Some coal mining faces use compressed air pipeline ventilation; contract underground mining operations Multiple private contract labor teams are managed by contract, and there are 3 contract labor teams in the accident area alone.
Fourth, Yuanjiangshan Coal Mine illegally mined steep coal seams under the old goaf flooded area.
During the mining of the 61 coal at the -500m level, the mine knew that there was water in the goaf above the working face, but still took a chance, took risks and worked wildly, and illegally mined steep coal seams under the old goaf flooded area.
Fifth, Yuanjiangshan Coal Mine has illegally applied for pyrotechnic products and the management is chaotic.
The mine knew that it was a mine that was suspended for construction, and repeatedly applied for pyrotechnics from the Civil Explosive Brigade of the Public Security Bureau of Leiyang City in the name of rectification. The seals of the civilian explosives warehouse were removed without authorization during the public security agency’s clearance of the pyrotechnics. , Use pyrotechnics to organize production, and take the method of receiving more and using less, and dispose of the remaining pyrotechnics in violation of regulations.
10. "12·4" major fire accident of Chongqing Yongchuan Diaoshuidong Coal Industry Co., Ltd.
At 17:17 on December 4, 2020, Chongqing Shengjie Renewable Resources Recycling Co., Ltd. (hereinafter referred to as Shengjie Recycling Company) recovered equipment at Diaoshuidong Coal Industry Co., Ltd. (hereinafter referred to as Diaoshuidong Coal Mine) in Yongchuan District, Chongqing A major fire accident occurred at that time, causing 23 deaths, 1 serious injury, and direct economic loss of 26.32 million yuan.
The reason was that when Shengjie Recycling Company used oxygen/liquefied petroleum gas to cut 2# and 3# water pump suction pipes in the -85m water pump chamber during the underground retracement operation in Diaoshuidong coal mine, the falling high temperature melt The slag ignited the grease deposited in the suction well of the sump. The burning of grease and oil from the rock formation produced a large amount of toxic and harmful smoke, which spread to the air inlet lane under the action of the fire and wind pressure, causing casualties.
Main lesson
First, the Diaoshuidong Coal Mine failed to organize the withdrawal operations in accordance with the reported withdrawal plan.
The downhole equipment withdrawal report and withdrawal plan submitted to the local government and relevant departments concealed the fact that the downhole withdrawal has been handed over to Shengjie Recycling Company to organize and implement, and the reported withdrawal plan did not include the downhole pump Into the withdrawal equipment list, but the pump was actually withdrawn.
The second is that Shengjie Recycling Company does not have the qualification for underground operations in coal mines, and the management of underground equipment withdrawal operations is chaotic. Personnel who have not obtained welding and thermal cutting operation certificates are arranged to perform underground cutting operations. Before the -85m water pump chamber gas cutting water pipe, Take measures to clean up or isolate the welding ballast and prevent splashes from falling into the suction wells where the oil is leaking from the rock.
Third, the safety management of Diaoshuidong Coal Mine and Shengjie Recycling Company is chaotic.
The coal mine inspection system has not been implemented, the personnel entering the mine have not carried self-rescuers, and the investigation and management of hidden dangers has not been in place.
