Metro Fire Safety And Rescue Technical Design Specifications - Metro, Automatic Fire Extinguishing,
Subway Within Security Accident, the chance to fire up there
. Cause fire due to a objective factors, such as the use of the unqualified Electric Aging equipment or equipment repairs; some are man-made factors, such as illegal operation or deliberate arson.Our current new version of "Metro Design" GB50157-2003 is in the original "design of the Underground Railroad," based on the combination of safety and security of today's Metro revised the new situation. Compilers in-depth analysis of current occurrence of the various subway fire disaster in particular, on the basis of causal conditions, and actively drew on the current international anti-elimination on all kinds of unexpected disasters, new technologies, new measures, and domestic types of buildings, the latest Disaster Prevention and Alarm , Fire and rescue and other technical requirements, the specification of the "disaster prevention and warning" section was focused on research in fire alarm, equipment Monitor , For help with the evacuation fire escape, and Project Materials and layout aspects of technical requirements and technical measures were significantly enriched and deepened.
(1) strict rules with non-combustible or Flame Retardant And equipment. Specification, a major subway project structure should be non-combustible, durable, reliable materials, such as Reinforced Concrete, for Metal Materials Only when necessary to allow the use. Decoration materials within the station, and Advertisement , Seat And other equipment are used in non-combustible or flame-retardant material with the provisions and regulations shall not use asbestos, Glass fiber And Plastic Products. Located in the underground tunnel for the various cables, require use of low smoke, halogen-free, flame retardant materials. In ventilation, Air conditioning System Pipe , Insulation and noise reduction materials are also provided with non-combustible material, only with difficulty in the local fire-retardant materials.
(2) calls for a perfect fire facilities. Domestic demand specification subway system has better fire-fighting facilities in all public places and within the tunnel shall be provided to set the location or distance Fire extinguisher And Fire Hydrant And the fire hydrant will be a reliable source, also provides some important equipment in the room to set up automatic Fire Extinguisher . Stations and other places by plane layout and structure and so on, divided into a number of Fireproof Partition, with each other Firewall Or fire doors Cut off .
(3) must have advanced warning and monitoring system. Specification must be set within the subway system, automatic fire alarm system, fire can occur in time alarm and monitoring, and directly control the operation of fire facilities and smoke linkage, exhaust system equipment, prevent expansion of delay and for disaster relief and evacuation of personnel to create facilitate the adoption of conditions.
(4) of emergency rescue and evacuation facilities. Underground stations and tunnel rescue and evacuation conditions than in poor, must create a safe passage conditions to maximize and standardize this made many mandatory provisions, such as subway stations at the Office of Fire Safety Division export not less than two and should Through Outer space, other fire exit area should not be less than two, and at least one exit through outer space. At the same time for the station should have a dedicated rescue workers into the underground passage.
When the fire occurred in the range of the tunnel, the train near the station should be allowed to enter due to the fire station has good conditions for rescue and evacuation. The current specification, single tunnel between the two, when the coherence length of greater than 600 m tunnel, the should be set to contact the channel, and should set the fire doors in the channel cut off so the car were able to flee to the nearest neighbor by the passage non-incident tunnel, then walk or take the rescue Vehicle Evacuated to safe areas.
Specification range in the underground stations and tunnels must be set to smoke, smoke and emergency ventilation system Emergency lighting And Broadcasting Systems, and eye-catching signs evacuation. In addition, consider the case of the need for power, at the station, platform, access and other personnel-intensive parts of the ground, set light to maintain visual continuity evacuation signs, possible to create conditions for safe evacuation.
