Abstract: Fire safety governance is both prioritized and challenged at the grassroots level. Grassroots fire safety governance is a systematic, long-term undertaking and a cornerstone of building a modern fire safety governance system and governance capacity. To further enhance the capacity for resolving fire hazards at their source and foster a collaborative working pattern of mass prevention and co-governance, this paper takes Dongguan city as a practical case study. Centering on three core questions of "who governs, what is governed, and how to govern", it presents how a closed-loop operational workflow for grassroots fire safety, comprising "patrol and detection, tiered response, closed-loop rectification, and enforcement and investigation", can be established under the "Unified Network Management" mechanism. Furthermore, by developing a "Three-in-One" grassroots fire safety informatization support system (namely, one platform for integrated coordination, one code for unified management, and one map for comprehensive oversight), the response speed and operational efficiency of firefighting forces are enhanced, the fire safety governance capabilities of grassroots teams are continuously strengthened, grassroots fire safety work is put on a solid and steady footing, and a comprehensive shift toward a "pre-incident prevention" paradigm is actively explored.

Key words: fire safety; hazard rectification; smart fire protection; grassroots governance; unified network management; long-term governance
