1General provisions
1.0.1 This code is formulated to regulate engineering construction and management for the publicsecurity and protection system of urban rail transit and to ensure the project quality , to protect thepersonal property in the urban rail transit areas, and to guarantee the security of urban rail transitoperations.
1.0.2 This code is applicable to the design, construction, inspéetion,acceptance and operationamanagement of the public security and protection system engineering of urban rail transit for newconstruction,extension and renovation, This code is not applicable to the tram systems.
1.0.3 The construction of the public security and protection system engineering of urban rail transitshall coordinate with the urban rail transit system, Security principle shall take priority, whereas openaccess to the urban rail transit by the public shall not be affected. The design and implementation ofsecurity and protection measures shall meet the requirements of urban rail transit for fast , efficient andpunctual operation.
1.0.4 The public security and proteetionsystem engineering of urban rail transit shall take multiplemeasures such as technical protection, physical protection, personnel protection, etc., in order toconstruct an integrated public security and protection system of urban rail transit. Technical protectionand physical protection shall coordinate with each other and bé capable of supporting personnelprotection.
1.0.5 The publie security and protection system engineering of urban rail transit shall be safe, open,scalable and flexible in its usage, and designed with the advanced technology for reliability and costeffective; the technical protection systems shall have inter-0perable communication capabilities.1.0.6 Phe engineering design, construction, inspection, acceptance and operational management of thepublic security and protection system of urban rail transit shall not only comply with this code , but alsocomply with the current relevant national laws,regulations and standards.

3 Basic requirements
3.1 Generalrequirements
3.1.1 The engineering design of the public security and protection system, of urban rail transit shall bebased on the optimum usage of the available public security resources, and shall comply with thesecurity policies, preventative procedures and preventative measures to construet a security system thatcoordinates deterrence, prevention, detection, delay and response, Phe design shall also enhance thecapabilities of prevention and control, reduce the possibility of seeurity threats occurring within theurban rail transit area, and minimize personnel injuries and property losses in case a threat occurs.
3.1.2 The protected objects in the urban rail transit shall be determined according to the area,location,and the technical characteristics. The security and'protection system engineering shall be capable ofemploying complete and relatively independentsecurity technologies and measures.The engineering design content of the public security and protection system of urban rail transit
3.1.3shall comprise the design of technical protection, physical protection, personnel protection, andemergency response procedure.
3.1.4 The engineering design of the public security and protection system of urban rail transit shallreserve space and arrange evacuation routes based on emergency rescue. The design shall includepassenger evacuation areas, first aid areas, rescue command posts, material distribution areas and
temporary storage areas
