On April 13, 2024, seven people died in a septic tank gas poisoning accident at a pig farm in Pengzhou City, Sichuan Province. In order to deeply learn the lessons of the accident, the Xiqing District Emergency Management Bureau acted quickly, innovated the safety service supervision model, built a strong safety defense line for limited space operations, and resolutely prevented hydrogen sulfide poisoning accidents in our district.
The law enforcement officer of the District Emergency Bureau said: "We immediately joined forces with the team of safety experts to carry out expert guidance services in key limited space enterprises in the region, and conducted a comprehensive and detailed inspection of the on-site management, rules and regulations, emergency rescue measures, and education and training of the limited space of the enterprise by consulting information, on-site inspection, communication and other methods, and comparing the on-site consultation form of key enterprises in industry and trade." At the same time, we have also provided all-round guidance services on the setting of warning signs at the entrances and exits of confined spaces, the implementation of physical isolation measures, the allocation of respiratory protective equipment and emergency rescue equipment, and the standardization of confined space operating procedures. For the problems found, the district emergency bureau communicated with the enterprises one by one, and answered the questions raised by the enterprises patiently and meticulously.
At the site of the sewage treatment station of a food processing plant, Mr. Wang, an expert, found that warning signs for limited space had been posted on the site, but the manhole cover of the sewage pool was not locked, and there were certain safety risks. The District Emergency Response Bureau immediately pointed out the problem to the person in charge of the enterprise and suggested that physical isolation measures be added to completely isolate the limited space and prevent people from entering by mistake or accidentally falling. After hearing this, the person in charge of the enterprise immediately expressed his determination to implement the rectification. "We did ignore the problem before, thinking that accidents could be avoided if the workers were careful," he says. Now it seems that this fluke mentality is very dangerous. The guidance service of experts is very helpful to our enterprise, and we will rectify the problems found by experts one by one to further improve the safety management level of limited space. ”
"Physical separation is a critical safety measure in confined space operations. By setting up physical isolation facilities such as fence locking, it can effectively prevent unrelated personnel from entering and exiting the risk area at will or carrying out limited space operations without approval, thereby reducing the possibility of accidents. ”
At the same time, the District Emergency Bureau also "moved" the training to the enterprise site in view of the potential risk of preventing hydrogen sulfide poisoning, and carried out a unique special training on the spot. During the training, the experts explained in detail the characteristics, hazards and preventive measures of hydrogen sulfide to the front-line operators on the spot in combination with key limited space places such as enterprise sewage pools, and deeply interpreted the "Safety Regulations on Limited Space Operations of Industry and Trade Enterprises", so that the employees of the enterprise deeply understood the key points and practical applications in the safety regulations. Combined with the emergency rescue equipment placed on the site of the enterprise, experts guide everyone to correctly master the wearing method of protective equipment and emergency measures in emergency situations.
A worker who participated in the training said: "In the past, we did not have enough understanding of the hazards of hydrogen sulfide, but this training made me deeply realize the importance of safety. In the future, I will definitely be more cautious and ensure my own safety. ”
In addition, the District Emergency Bureau also made full use of new media platforms such as the "Xiqing Emergency" official account to comprehensively strengthen the popularization of safety knowledge and preventive measures for confined space operations. Combined with the case of hydrogen sulfide poisoning accident in confined space, the safety operation specifications and emergency rescue measures for confined space operations are popularized to the public, the causes of the accident are deeply analyzed, and the majority of employees are warned to strictly abide by safety regulations and effectively enhance their awareness of self-protection.
Yue Hui, deputy director of the District Emergency Management Bureau, said: "With the gradual warming of the climate, it is a high incidence period for accidents such as hydrogen sulfide poisoning. Safety is no small matter, and we must always be vigilant. Through measures such as expert guidance services, on-site special training and special law enforcement inspections, we hope to improve the safety awareness and skill level of operators, and truly build a safe line of defense for confined space operations. ”
In the next step, the District Emergency Management Bureau will continue to deepen the special rectification of limited space operations, start from the details, make efforts to implement them, strictly enforce standards, promote implementation, carry out expert guidance services in enterprises, increase law enforcement inspections, adhere to the bottom line of safety production, promote the standardization of limited space safety management of enterprises, and resolutely prevent the occurrence of hydrogen sulfide poisoning accidents.
