[ZEROSAI Implementation Case] Improving the Rules for Evacuation Actions

Notification of danger through emails and disaster prevention lights! Case studies of disaster recovery construction.

We will introduce the implementation results of the disaster prevention system "ZEROSAI." At the Hokkaido Development Bureau, river construction was being carried out in areas frequently affected by flooding due to heavy rain. There was no established rule for evacuation actions based on the understanding of water levels upstream of the river and specific numerical settings, resulting in evacuation actions during flood disasters being left to individual judgment, leading to the introduction of "ZEROSAI." After its implementation, notifications of danger were effectively communicated through emails and disaster prevention lights when water levels upstream of the river rose, allowing workers to take swift evacuation actions. Additionally, knowing the real-time water levels upstream of the river, which is usually unoccupied, provided peace of mind for carrying out work. 【Case Study】 ■ Objectives - River construction in areas frequently affected by flooding due to heavy rain - Evacuation actions during flood disasters were left to individual judgment ■ Effects - Even during work, the situation could be understood through disaster prevention lights, ensuring compliance with on-site conduct guidelines - Danger was communicated through notifications via email and disaster prevention lights, leading to thorough and swift evacuation actions - Real-time awareness of water levels upstream of the river, which is usually unoccupied, allowed for peace of mind while working *For more details, please refer to the PDF document or feel free to contact us.
