"Changshu Economic Development Zone, Xinggang Road! Ammonia transport vehicle Su E6W175 is leaking, requesting support!" On the morning of November 29, 2025, at 9:30 AM, with this emergency call, a joint emergency drill simulating an ammonia leak during hazardous chemical road transport officially began. The exercise was co-hosted by Jiangsukuerjie Logistics Co., Ltd. and Jiangsu Yuntianxia International Supply Chain Management Co., Ltd., with coordinated participation from fire, environmental, and public security departments. Through a realistic exercise of 'real scenarios, real response, and real coordination,' a strong safety production defense line was established.
The hazardous chemical transport vehicle Su E6W175, carrying 10 tons of ammonia, was driving on Xinggang Road. To avoid a suddenly changing vehicle, the driver had to brake abruptly, causing the ton barrel inside the vehicle to collide, damaging the valve interface. Ammonia leaked and emitted a pungent odor, and there was a factory 500 meters downwind from the accident site. The situation was critical!
Escort officer Guo Xiao’ou immediately noticed the leak, quickly donned a gas mask, got out of the vehicle to inspect, and, after confirming the leakage from the bottom valve of the ton barrel, notified the driver, Qi Lin. Qi Lin immediately turned off the engine and engaged the handbrake, while Guo Xiao’ou placed warning triangles 100 meters behind the vehicle. Both called 110 and 119 emergency numbers simultaneously and accurately reported the incident to the company's emergency office, then retreated upwind to a safe area while warning passing vehicles and advising nearby factory security to close doors and windows. The initial response was proper and efficient.
Upon receiving the report, the company's emergency office immediately activated a Level II emergency response, sounding internal alarms. Chief Commander Cha Yansong promptly deployed resources, with six groups from the emergency command headquarters rushing to the scene equipped with protective suits, leak-stopping tools, and firefighting equipment, while relevant government departments responded simultaneously.
The alert and evacuation team arrived first to set up a safety perimeter, put up warning signs, and control traffic; the emergency rescue team, in full protective suits, entered the core area to deploy water curtain guns to dilute the leaking ammonia; the environmental monitoring team quickly set up monitoring points to track gas concentration changes. The on-site command center was established in a safe area upwind. After listening to reports from each team, Cha Yansong clarified the division of tasks, forming a four-in-one rescue framework: 'alert and control, emergency leak sealing, environmental monitoring, and medical rescue,' fully unleashing coordinated government-enterprise effectiveness.
The emergency rescue team members, wearing full protective suits and under water gun cover, used wooden leak-stopping wedges and sealing paste for precise operation, successfully sealing the leak. Subsequently, pollutants were handled according to the standardized 'solidify - contain - collect - neutralize' process: building embankments with sand to prevent spreading, neutralizing residual ammonia with lime, collecting pollutants into specialized waste barrels, strictly following environmental regulations.
Meanwhile, the medical rescue team provided oxygen care to the simulated unwell driver and assessed transport needs. The accident vehicle was safely towed away, and environmental monitoring data showed toxic and harmful gas concentrations dropped to safe levels, fully eliminating risks at the scene.
At the end of the drill, all participants lined up for assembly, with supervisor Wang Bo providing a review and Chief Commander Cha Yansong delivering a closing speech. This 90-minute drill covered the full process of accident reporting, emergency response, on-site handling, and post-incident recovery, testing the scientific soundness of the 'Emergency Plan for Hazardous Chemical Road Transport Accidents,' honing emergency team coordination, and enhancing all participants' risk prevention and self-rescue and mutual-rescue skills.
