【 Weak current College 】 Metro fire safety and rescue technical design requirements specification-Power By 【 China power house network 】

Subway security incidents to the chance of fire occurred. Raises the fire due to objective factors, such as the use of a qualified electrical equipment or device aging neglect; some are human factors, such as the illegal operation, or purposefully arson.
　　
The current version of the MTR design code GB50157-2003 is in the original "subway design code, combined with today's new subway security situation. Establishment in the in-depth analysis of various Metro nowadays disasters especially fire causal circumstances on the basis of the positive lessons of the current international againstdisappears the sudden disaster in new technologies, new measures, as well as the domestic each kind of building the latest disaster and alarm, fire and rescue, and other technical requirements and specifications of the disaster preparedness and alert "section has been focused on research in disaster prevention alarm, equipment monitoring, fire rescue and evacuation, and engineering materials, and flat layout and other aspects of technical requirements and technical measures to substantially enriched and deepened.
　　
(1) strictly adopts non-combustible or fire retardant materials and equipment. Specification of requirements, the structure of major works of the subway should be non-combustible, durable and reliable material, such as reinforced concrete, metal material is only allowed when necessary. Station interior decoration materials, as well as advertising, seat, the equipment are provided with non-combustible or fire retardant materials, and shall not use of asbestos, glass and plastic products. Located in the underground tunnels of various cables require a low smoke, halogen free, flame-resistant material. In ventilation and air conditioning pipes, insulation and noise reduction material also provides for the use of combustible materials, only in the local difficulties flame retardant material used.
　　
(2) requires a sophisticated fire-fighting facilities. Specification requires the system internal demand has the perfect fire facilities, in all public areas and tunnels shall be in accordance with the regulations of the venue or distance setting fire extinguishers and fire hydrants and fire hydrant should have a reliable fire-fighting water, also provides a number of important equipment room to set up automatic fire suppression equipment. Station etc press layout and structure, and other characteristics, divided into several fire partitions, each with a firewall or a fire door panel.
　　
(3) must have advanced alarm and monitoring system. Specification requires the system must be set in the automatic fire alarm system, fire alarm and monitoring in a timely manner, and can directly operate the linkage control fire-fighting facilities and smoke, smoke exhaust system devices, preventing the disaster it expanded and to rescue and evacuation personnel create conditions to facilitate adoption.
　　
(4) emergency rescue and evacuation facilities. Underground stations and tunnels in the rescue and evacuation conditions are poor, you have to create a safe conditions, specification, as many of the mandatory provisions, such as the station platform and the station Hall fire partitions security exports should not be less than two and should pass through the external space, other fire partitions security export should not be less than two, and at least one exit through the external space. At the same time the station should be for aid workers to enter the underground private channel.
　　
When the fire in the tunnel, train should try into the neighbouring station, the station has good conditions for fire and rescue and evacuation. The current specification provides for two-lane tunnel, when tunnel coherence length greater than 600 meters, you should set the contact channels, and channel settings so that the fire doors cut off, the car to the nearest escape from liaison channels to the adjacent non-accidents in tunnels, then walk or take the rescue vehicle evacuation and safety.
　　
Specification requirements in underground stations and tunnels must be set up in smoke, smoke extraction and ventilation system, emergency lighting and the broadcasting system, as well as the prominent evacuation signs. Also consider the needs of power-off situations, station, platform, channel, and other personnel-intensive part of the ground, set the keep Visual continuous light emitting evacuation signage, maximize the creation of a safe evacuation.
