This study introduces the Crown Water Spray Equipment for Forest Fires Protection (CWSEFFP), a novel system designed to prevent the spread of large-scale forest fires and protect village communities, cultural heritage sites, and forest recreational facilities. The devastating 2005 Yangyang forest fire in South Korea, which destroyed Naksan Temple and 22 state-designated cultural properties, highlighted the urgent need for enhanced fire prevention systems. CWSEFFP I and II are designed to spray water over areas of 200 m × 80 m and 2000 m × 80 m, respectively, using strategically installed large nozzles. Since 2012, CWSEFFP I has been implemented in 240 locations across South Korea, with plans to deploy CWSEFFP II in 2024. This study details the design, functionality, and technical specifications of CWSEFFP, emphasizing its role in mitigating damage in the Wildland-Urban Interface (WUI) areas. The system exemplifies an aggressive approach to forest fire prevention, addressing the increasing frequency and intensity of fires globally. It not only suppresses active fires but also prevents their spread, thereby offering a robust solution for safeguarding vulnerable communities.
