Foreword
According to the requirements of Document JIANBIAO [2007] No.125-"Notice on Printing the Development and Revision Plan of National Engineering Construction Standards and Codes(the First List)in 2007"and Document JIANBIAO[2009]No.94-"Letter on the Modification of RevisionPlan forCodeof Design onBuildingFireProtection and Prevention and Code forFireProtectionDesign of Tall Building" issued by the Ministry of Housing and Urban-Rural Development,this code was revised byintegratingGB50016-2006Codeof Design on BuildingFireProtectionandPrevention and GB 50045-95CodeforFireProtectionDesignofTallBuildingbyTianjinFireResearch Institute and Sichuan Fire Research Institute of Ministry of Public Security,together with other organizations.
During the revision of this code,the working group followed the relevant national principles and policies in capital construction,implemented the fire policy of "prevention first and combining prevention with fire-fighting",learned the lessons from major fire accidents in recent years, summarized practical experiences in fire protection design of buildings and achievements in fire science and technology at home and abroad,carried out researches on the new conditions and problems in engineering construction and the issues arisen during the code implementation, seriously studied and learned experiences from developed countries, carried out serices of research projects,technical discussions and necessary tests,solicited wide opinions from design.production,construction,scientific research,education and fire supervision organizations,etc.and finalized this code based on authority approval.
This code includes twelve chapters and three appendixes. Its main technical contents include: requirements for fire hazard classification of production and storage and classification of high-rise buildings, basic requirements for fire-resistance class of industrial and civil buildings such as factory buildings, storages,residential buildings and public buildings and basic requirements for fire-resistance rating of building elements,plane arrangement,fire compartmentation,fire separation,building construction forfireprotection,fire separation distance and fire protection facilities,basic measures and requirements for explosion prevention of industrial buildings;basic requirements for distance,exit width, exit stairway,emergency lighting and evacuation indicating signs,and exit and exit door of industrial and civil buildings; basic requirements for fire separation distance,grouped layout and storage volume of Class A, B,C liquid and gas tanks(tank farms)and stackyard for combustibles;basic requirements for fire protection design of timber building and urban road tunnel engineering; basic requirements for firefighting and rescue area,fire vehicle access road,fire service access elevator and other facilities set to meet the fire fighting and rescue requirements; fire protection requirements in such aspects as heating, ventilating and air conditioning and electricity of buildings as well as basic requirements for fire power supply,distribution lines etc. of fire-fighting electrical equipment.
Therehavebeen some significant changes of this codeover GB50016-2006Codeof Design om BuildingFireProtectionandPreventionandGB50045-95(2005edition)CodeforFireProtection DesignofTall Buildingasfollows:
.1， 1.Codeof Design onBuildingFireProtection andPreventionandCodeforFireProtection Design of Tall Building are combined,with their inconsistent requirements amended.The residential buildings are classified by their building height.
2. Two chapters("Fire fighting and rescue facilities" and "Timber buildings")are added, improving the relevant requirements of fire-fighting and rescue and standardizing the fire protection requirements of timber buildings.
3.Fire protection requirements of thermal insulation system for buildings are supplemented. 4. Specific requirements are made for the arrangement of fire-fighting facilities and the relevant
contents are improved;the requirements for the design of fire water supply systems,indoor and outdoor fire hydrant systems and smoke control and smoke exhaust systems are specified in corresponding national standards respectively.
5. Fire protection requirements of high-rise residential buildings and the high-rise civil buildings with building height greater than 10Om are properly improved.
6.Fireprotection requirements of roofed commcrcial common pedestrian area when it is used for the evacuation of the buildings on both sides are supplemented; the designed occupant density of the business hall and exhibition hall of building materials,furniture and light fixture stores are amended and supplemented.
7. Fire protection requirements for underground storages,logistics buildings,large combustible gas tanks (tank farms), liquid ammonia tanks and LNG tanks are supplemented,and the fire separation distance of liquid oxygen tanks and the like are amended.
8. The relevant requirements for preventing vertical or horizontal fire spread in buildings are improved.
Provisions printed in bold type in this code are compulsory and must be implemented strictly The Ministry of Housing and Urban-Rural Development of the People's Republic of China is in
charge of the administration of this code and the explanation of compulsory provisions;the Ministry of Public Security of the People's Republic of China is responsible for the routine management;authorized by FireDepartment of MPS, Tianjin Fire Research Institute and Sichuan Fire Research Institute are responsibleforthe explanation ofspecific technical contents.
Whereas this code is a comprehensive technical standard for fire protection with strong policy and technology orientations and wide coverage,all relevant organizations arekindly requested to summarize your experiences in actual practice and scientific research during the process of implementing this code, and relevant comments,recommendations and questions,whenever necessary,can beposted orpassed on to the Fire Department of MPS(Address:No.70 Guang'anmen South Street,Xicheng District, Beijing,100054,China)for reference in the future revision and for explanation by Tianjin and Sichuan FireResearchInstitutes of MPS.
