Preparation Instructions
This specification is prepared by the Shanghai Fire Science Research Institute of the Ministry of Public Security in conjunction with the specification preparation team composed of relevant design, public security departments and production plants in accordance with the requirements of the former State Planning Commission's Notice No. 2630 [1986]. During the preparation of this specification, in accordance with the relevant principles and policies of national capital construction and the fire protection work principle of "prevention first, prevention and control combined", a relatively extensive investigation and research was conducted on the current status of the configuration of fire extinguishers in industrial and civil buildings; it summarized the domestic practical experience over the years, absorbed the results of the verification and extinguishing tests on the fire extinguishing levels of various types of fire extinguishers such as halogenated hydrocarbons, dry powder, carbon dioxide, foam, etc., and drew on the relevant standard specifications of the United States, Britain and Australia; and solicited opinions from some provinces, autonomous regions, municipalities directly under the Central Government and some ministries and commissions of design, scientific research, colleges and universities, public security fire and user units. After many discussions and revisions, it was finally reviewed and finalized in conjunction with relevant departments. This specification is divided into six chapters and six appendices. Its main contents include: general principles, the danger level of the fire extinguisher configuration site and the fire extinguishing level of the fire extinguisher, the selection of fire extinguishers, the configuration of fire extinguishers, the setting of fire extinguishers, the design and calculation of fire extinguisher configuration, etc. In view of the fact that this code is formulated for the first time, in the process of implementing this code, all units are requested to combine engineering practice and scientific research, carefully summarize experience, accumulate relevant information and data, and send them together with opinions and suggestions on this code to the Shanghai Fire Science Research Institute of the Ministry of Public Security (address: No. 601, Zhongshan South 2nd Road, Shanghai, Postal Code: 200032) for reference during revision.

Chapter 1 General
Article 1.0.1 This specification is formulated in order to rationally configure fire extinguishers, effectively put out initial fires in industrial and civil buildings, reduce fire losses, and protect the safety of people and property.
Article 1.0.2 This code applies to newly built, expanded, and renovated industrial and civil construction projects for the production, use, and storage of combustibles. This code does not apply to factories (warehouses) for the production and storage of gunpowder, explosives, ammunition, pyrotechnics, and fireworks, as well as ordinary residential buildings with nine floors or less. Article 1.0.3 The type, specification, quantity, and location of the configured fire extinguishers shall be included in the architectural design content and shall be indicated on the engineering design drawings. Article 1.0.4 In addition to implementing the provisions of this code, the configuration design of building fire extinguishers shall also comply with the requirements of the relevant current national standards and specifications.

Chapter 2
Hazard Level of Fire Extinguisher Configuration Site and
Fire Extinguishing Level of Fire Extinguisher
Article 2.0.1 Hazard Level of Fire Extinguisher Configuration Site in Industrial Buildings shall be divided into the following three levels according to the fire hazard of the articles produced, used and stored, the quantity of combustibles, the speed of fire spread and the difficulty of fire fighting: 1. Severe Hazard Level: Sites with high fire hazard, many combustibles, rapid fire spread or easy to cause major fire losses; 2. Medium Hazard Level: Sites with high fire hazard, many combustibles and rapid fire spread
3. Light Hazard Level: Sites with low fire hazard, few combustibles and slow fire spread.
For examples of hazard levels of fire extinguisher configuration sites in industrial buildings, see Appendix III of this specification. Article 2.0.2 The danger level of the places where fire extinguishers are placed in civil buildings shall be divided into the following three levels according to the nature of their use, fire hazard, number of combustibles, speed of fire spread, and difficulty of fire fighting: 1. Severe danger level: places with complex functions, high electricity and fire use, expensive equipment, high fire hazard, many combustibles, rapid fire spread after fire or easy to cause major fire losses;
2. Medium danger level: places with high electricity and fire use, high fire hazard, many combustibles, and rapid fire spread after fire;
3. Light danger level: places with low electricity and fire use, low fire hazard, few combustibles, and slow fire spread after fire.
For examples of the danger level of places where fire extinguishers are placed in civil buildings, please see Appendix III of this specification. Article 2.0.3 The types of fire should be divided into the following categories according to the materials and their combustion characteristics:
