An emergency response drill was launched recently after a simulated report from a patrol officer at the Nanjiao station of Jiacheng Group's Jiaxing Natural Gas Pipeline Network Operation Co., Ltd. The drill involved a scenario where a third-party excavator damaged a pipeline, causing a significant gas leak with concentration levels exceeding safe limits by over 20%.
This exercise was conducted against the backdrop of the 25th National Work Safety Month in June, which carries the theme of promoting safety awareness and emergency response capabilities among all personnel, with a focus on identifying and rectifying risks and hidden dangers. As the city's operational lifeline, the safety of the natural gas pipeline network is of paramount importance to countless households. The drill aimed to deepen ongoing efforts in hazard investigation and rectification while enhancing emergency handling capabilities.
Upon commencement, all emergency teams swiftly mobilized. The series of coordinated actions included patrol verification, alerting authorities, establishing security perimeters and evacuations, concentration detection, cutting off the gas supply, venting operations, and emergency repairs. The production safety accident emergency plan was activated immediately, with patrol personnel quickly deploying warning tape. Firefighting, public security, and environmental protection departments also arrived promptly at the scene.
To ensure a continuous and stable gas supply to users along the line, the pipeline network company simultaneously implemented a reverse supply plan, utilizing the already operational Nanjiao-T3 pipeline to transport gas in the opposite direction. The entire simulation, from the initial alert to the completion of repairs and restoration of supply, was completed within 40 minutes.
Lu Jia, Deputy General Manager of the pipeline network company, explained that the company is leveraging remote monitoring and control technologies such as drone inspections and an urban lifeline anti-external damage early warning system. This approach represents a comprehensive upgrade to the safety management and control model for the pipeline network, shifting the focus of pipeline protection from reactive emergency repairs to proactive defense.
The drill site showcased various advanced emergency equipment, including an oil and gas pipeline emergency rescue command vehicle, intelligent gas detection terminals, and explosion-proof wheeled inspection robots. These tools highlighted the power of technology in enhancing safety. The transition from relying on human vigilance to technical safeguards and then to intelligent protection is weaving an increasingly dense, multi-dimensional, and intelligent safety net for the pipeline network.
In recent years, Jiacheng Group has extended its safety oversight to every aspect of urban construction and operation. In the natural gas sector, the company has established a "multi-source, large-loop network" gas supply structure, strengthening its multi-layered defense. In scenic and commercial areas, it conducts comprehensive "health check" inspections for gas, fire safety, and building structures, while also implementing a "one file per household" system to eliminate hazards in older buildings and rented shops. At construction sites, a "smart construction site" system provides real-time monitoring of major hazardous projects such as deep foundation pits and high-formwork support. A comprehensive safety network covering "gas, water, electricity, fire, and construction" safeguards every corner of the city.
