This morning, Anhui Provincial Transportation Holding Group and multiple departments jointly held a comprehensive emergency drill for the safety control of limited space operations on the Cross-River Bridge at the Second Bridge of the Yangtze River in Wuhu. The drill was listed as a provincial safety emergency drill project in 2021.
Limited space refers to a closed or partially closed, relatively narrow place for import and export, which is prone to the accumulation of toxic and harmful, inflammable and explosive substances or insufficient oxygen content due to poor natural ventilation, which brings safety hazards such as poisoning or suffocation to the operator.
The drill simulated that in the enclosed space (limited space) of the steel box girder box body of the main bridge of the Second Bridge of the Yangtze River in Wuhu, an operator was engaged in paint anti-corrosion painting operations, and due to the accidental damage of the gas mask was not found in time, resulting in a poisoning and suffocation accident. After the accident, the on-site personnel and highway management, local fire protection, medical and other units jointly launched a series of emergency rescue measures.
During the drill, the four working groups of emergency self-rescue, fire rescue, medical rescue and traffic control responded quickly and cooperated closely, and took measures such as emergency self-help, information reporting, on-site control, preliminary first aid and safe transfer at the first time after the accident, and successfully treated the injured.
Chen Zhaolong, director of the Wuhu Erqiao Pipe and Nutrient Center, explained: A small space is only 3 meters wide, each small space has only 1 safety door, the height of the safety door is only about 1.3 meters, the width is only 60 centimeters, it is more difficult for a person to pass, and we also have to transport the injured out during the rescue process. It took us only 20 minutes from calling the police to getting the poisoned person to the 120 car, and only 6 minutes from inside the box to transfer him to safety.
The drill was hosted by Anhui Anhui Wantong Expressway Co., Ltd., and was specifically undertaken by anhui traffic control group maintenance management center and Wuhu management center responsible for the management of the second bridge of the Yangtze River in Wuhu and the operation and management of the expressway. At present, Anhui Traffic Control Group manages the Ma'anshan Yangtze River Bridge, Wuhu Yangtze River Second Bridge, Chizhou Yangtze River Bridge, Anqing Yangtze River Bridge, Wangdong Yangtze River Bridge and other 5 cross-river special bridges, complex structure, especially the closed space formed by the main girder of the hollow structure, which brings great difficulty to internal maintenance and maintenance operations, and improper operation is prone to production safety accidents. This drill,
In the form of simulated actual combat, the emergency disposal work of the limited space operation across the Yangtze River Bridge was tested, the safety control awareness of the limited space operation of each unit was further strengthened, and the coordination and cooperation and emergency handling ability of the relevant units in the emergency were improved.
Li Chen, deputy director of the Wuhu Management Center of Anhui Traffic Control Group, said, "We have continuously enhanced our emergency management and control capabilities during the exercise, enhanced the actual combat capabilities of the emergency response team, and tested the scientific and operability of our emergency plan." Through such drills, in the future high-speed operation process, we encounter emergencies like this, and we can better deal with emergencies. ”
