The increasing frequency of large-scale wildfires driven by climate change, along with the rising number of high-rise buildings, has highlighted the limitations of conventional firefighting methods in inaccessible environments. This study explores the potential of a gas hydrate-based extinguishing agent, designed for projectile deployment, to provide rapid suppression in such scenarios. Gas hydrates release inert gases upon thermal decomposition, suffocating flames effectively. Experiments followed the Technical Standards for Small-Space Fire Extinguishing Devices using chambers of 0.04 m³, 0.12 m³, and 0.36 m³ with Class A (wood) and Class B (flammable liquid) fire models. Results demonstrated successful suppression in small chambers, but failure in the largest chamber, indicating the limitation of suffocation-based mechanisms in larger volumes. These findings provide a baseline for developing gas hydrate-based extinguishing projectiles. Future research will aim to improve agent reactivity, enhance gas expansion, and establish standardized evaluation protocols for application in large or open-space fires.
