Recently, Hubei Province has seriously pursued and held responsible persons responsible for gas explosion in Yanhu community trade market, Zhangwan District, Shiyan City. 34 public officials including 11 provincial management cadres were removed and removed from office.
At 6:42 on june13,2021, a gas explosion occurred in Yanhu community trade market, Zhangwan District, Shiyan City, causing 26 deaths and 138 injured.
After the accident, general secretary Xi Jinping immediately made important instructions to urge the wounded to be fully rescued, to do well the relief work of the relatives of the casualties, to find out the cause as soon as possible, and to seriously investigate the responsibility. Premier Li Keqiang and other central leaders gave instructions and put forward requirements for rescue, treatment of the wounded, investigation and treatment, etc. The Ministry of emergency management, the Ministry of housing and urban rural development and the Ministry of health dispatched a working group to the site for guidance. The safety committee of the State Council shall be listed for supervision and dispatch a supervision team to guide the accident investigation on site.
After investigation,The direct cause of the accident is the serious corrosion and cracking of natural gas medium pressure steel pipes, and the leakage of natural gas in the closed space of the river below the building, and the explosion of the oil and gas pipelines in restaurants and restaurants.The accident also exposed hidden dangers caused by illegal construction, long-term failure to investigate and rectify hidden dangers, chaotic property management, improper on-site emergency disposal and other problems. The accident is a major production safety responsibility accident.
The investigation found that Shiyan Dongfeng zhongran company was directly responsible for the accident. 11 relevant personnel such as Huang, the person in charge of the company, were suspected of committing crimes, and criminal coercive measures had been taken by the judicial organ. China Gas Holding Co., Ltd. and its affiliated Shiyan Dongfeng zhongfuel company, China Resources Land (Wuhan) Property Management Co., Ltd. and its affiliated runlian property, Dongfeng Motor Group Co., Ltd. and its original affiliated Dongfeng gas company are responsible for the accident. The 32 responsible persons of the above units shall be investigated for responsibility by relevant competent departments and superior units in accordance with discipline and regulations.
Handling results: the person responsible for the accident was given a party inspection and removed from office by government affairs, 2 were removed from office by government affairs, 6 were given a serious warning within the Party (including 2 removal), 3 were given a serious warning within the party and recorded a major demerit in government affairs (including 1 removal), 2 were recorded a major demerit in government affairs (including 1 removal), 4 were given a warning within the party, 5 were given a government warning, 6 were admonished, and 5 were instructed to make a written inspection.
In order to prevent similar accidents from happening again, Xiaohan today recommends a passive optical fiber laser leakage monitoring system
PetroChina has used our company's "passive optical fiber laser leakage monitoring system" to build the world's first on-line monitoring network for long-distance buried pipelines on the Shaanxi Beijing No. 4 long-distance pipeline with the largest pipe diameter and the highest pressure in China. The system mainly carries out 24-hour on-line real-time monitoring for buried pipelines and insulated joints on the fourth Shaanxi Beijing line, which mainly solves the problem that the gas leakage of buried pipelines can not be monitored before, and realizes the real-time on-line monitoring of leakage in the closed space traversed by natural gas pipelines without power supply. In case of minor leakage of local buried pipeline, it can be found in time, and the alarm signal can be transmitted to the monitoring center through the monitoring system to locate and remind the management personnel to repair in time. Avoid the situation that the disposal cost is too high or cannot be disposed due to leakage. The product has the advantages of high detection sensitivity, fast response speed, good stability, adaptability to the buried environment, no maintenance, the same life cycle as the pipeline, and real-time upload of monitoring data. The overall state of the monitoring point can be intuitively displayed through the monitoring platform to realize the all-day monitoring of the operation state of the buried pipeline.
The project has been successfully operated for four years and has been highly praised by the owner. Through the application of the system, it has realized the investigation of potential leakage of natural gas in the early stage, which plays an important role in preventing, controlling and eliminating potential leakage of important nodes and emergency disposal. At the same time, it has greatly reduced the daily patrol operation and maintenance cost of the operating company and greatly reduced the maintenance personnel, Improve the comprehensive level of natural gas pipeline safety management.
The occurrence of safety accidents is accidental and inevitable, especially in urban excavation and construction in high consequence areas, which will inevitably pose a threat to buried pipelines. Timely early warning is the guarantee of people's lives and the safety of national property.
