FEIS took part in the 2023 joint environmental emergency drill co-organized by the Ecological Environment Bureau, Emergency Management Bureau and Fire Rescue Department of Fengxian District, Shanghai as well as Hangzhou Bay Economic and Technological Development Zone. The drill, which aims to improve environmental emergency responses, includes immediate mobilization, evacuation, notification for police, internal reporting and self-rescue. During the event, FEIS also collaborated with the governmental agencies for the rescue mission, controlled air pollution and responded to wastewater discharge caused by the emergency. The exercise tested the effectiveness of the firefighting apparatus and emergency response of FEIS while strengthening the coordination between FEIS and the local government to enhance the plant’s preparedness for actual emergencies.
