en.Wedoany.com Reported - The Department of Housing and Urban-Rural Development of Sichuan Province, in conjunction with the Provincial Department of Transportation, has issued the "Sichuan Province Highway Engineering (Tunnel) Fire Protection Technical Guidelines" (hereinafter referred to as the "Guidelines"), which will take effect on July 1 this year, providing a unified technical standard for the design, review, and acceptance of fire protection in highway tunnels across the province.

The Guidelines systematically cover key technical aspects including fire-resistant structures, fire water supply, smoke control and exhaust, fire detection and alarm, emergency lighting, fire power supply, and fire acceptance inspection. The document integrates relevant technical standards from the transportation and housing and urban-rural development sectors, establishes fire protection technical requirements tailored to highway tunnel scenarios, and proposes actionable provisions for fire compartmentation, fire linkage control, and dedicated evacuation passages.

The Guidelines specify that the design of highway tunnel fire protection shall follow the principle of "prioritizing personnel evacuation and rescue, supplemented by property preservation and fire extinguishing." Fire protection facilities must be designed and implemented concurrently, with their configuration levels linked to tunnel classification based on factors such as tunnel length and traffic volume, to reasonably determine the water demand for extinguishing systems and the duration of fire continuity. The document also sets clear requirements for fire water supply sources, conditions for installing smoke control and exhaust systems, placement of fire detectors, duration and illuminance of emergency lighting, and establishes specific content and criteria for on-site evaluation during fire acceptance inspection.
