Preparation Instructions
This specification is adjusted to a national standard in accordance with the notice of the Ministry of Construction [1991] Jianbiao No. 727, and is prepared by the Planning and Design Institute of China National Petroleum and Natural Gas Corporation in conjunction with the Survey and Design Institute of Daqing, North China, Sichuan Petroleum Administration Bureau, the Survey and Design Institute of Petroleum Pipeline Bureau, and the Daqing Municipal Public Security Fire Brigade.
During the compilation process, in accordance with the relevant principles and policies of national capital construction and the fire protection work principle of "prevention first, prevention and fire control combined", the experience and lessons learned in fire protection design and production management of factories, stations, warehouses and well sites related to oil and gas fields and pipeline systems were systematically investigated and summarized. The reasonable parts of the standards of the former Ministry of Petroleum Industry "Oilfield Construction Design Fire Protection Code" and "Gas Field Construction Design Fire Protection Regulations" were adopted, and the relevant contents of domestic and foreign fire protection standards and advanced technical achievements applicable to fire protection of oil and gas fields and pipeline projects were absorbed. After soliciting opinions from all parties many times, the relevant departments jointly finalized it. In view of the fact that this specification is a comprehensive fire protection technical specification with strong policy and technical nature and a wide range of coverage, it is hoped that all units will combine engineering and production practices, carefully summarize experience, and pay attention to accumulating information during the implementation process. If you find that there is a need for modification and supplementation, please send your opinions and relevant information to the Standards Department of our company's Planning and Design Institute (Box 938, Xueyuan Road, Beijing, Postal Code 100083) for reference in future revisions. After the promulgation and implementation of this code, it will replace the original "Code for Fire Protection Design of Oilfield Construction" (SYJ1-85) and "Regulations on Fire Protection Design of Gasfield Construction" (SYJ2-79).

Chapter 1 General
Article 1.0.1 This specification is formulated to implement the principle of "prevention first, prevention and fire prevention combined" in the design of oil and gas fields and pipeline projects, unify design requirements, prevent and reduce fire losses, and ensure the safety of production and construction and the lives and property of citizens. Article 1.0.2 This specification applies to the design of oil and gas production, storage and transportation projects of newly built, expanded and rebuilt oil and gas fields and pipeline projects. It does not apply to underground and semi-underground oil and gas plants, stations, depots and offshore oil projects.
Article 1.0.3 The fire protection design of oil and gas fields and pipeline projects must comply with the relevant national policies and guidelines, combine with reality, and correctly handle the relationship between production and safety. Actively adopt advanced fire prevention and fire extinguishing technology to ensure safe production and be economical and practical. Article 1.0.4 In addition to implementing this specification, the design of oil and gas fields and pipeline projects shall also comply with the provisions of relevant national standards and specifications in force.

Fire Hazard Classification
Article 2.0.1 The fire hazards of production shall be divided into five categories according to Table 2.0.1. Classification of fire hazards in production
Production categories
Characteristics of fire hazards
Production using or producing the following substances
1.Liquids with a flash point <28°C
2.Gases with a lower explosion limit <10% (volume percentage)Production using or producing the following substances
1.Liquids with a flash point of 28°C to <60°C
2.Gases with a lower explosion limit ≥10% (volume percentage)Table 2.0.1
3.Chemical flammable hazardous solids that do not belong to Class A and can form explosive mixtures with air Suspended dust of explosive mixture
Use or produce liquid with flash point ≥60℃
Production with the following conditions
1. Processing of non-combustible substances, and frequently producing radiant heat, sparks or flames at high temperature or in a molten state
2. Various productions using gas, liquid, solid as fuel or burning gas or liquid for other purposes
Production using or processing non-combustible substances at room temperature Note: ① This table adopts part of the provisions of the current national standard "Code for Fire Protection Design of Buildings". ② For examples of fire hazard classification of production, see Appendix III. Article 2.0.2 When there are different types of production in the oil and gas production plant or fire compartment, the classification shall be determined according to the part with greater fire hazard. When the proportion of the part with greater fire hazard to the area of this floor or this fire compartment is less than 5%, and the accident is not enough to spread to other parts, or fire prevention measures can prevent the spread of fire, it can be determined according to the part with less fire hazard. Article 2.0.3 The fire hazard classification of stored items shall be divided into five categories according to the current national standard "Code for Fire Protection Design of Buildings". The fire hazard classification and examples of commonly used stored items in oil and gas fields and pipelines shall be implemented in accordance with Appendix 4.

Chapter 3 Regional Layout
Chapter 3.0.Article 1 The general layout of the region should be reasonably determined by comprehensive economic comparison based on factors such as the fire hazards of oil and gas plants, stations, depots, adjacent enterprises and facilities, terrain and wind direction.
Article 3.0.2
Oil and gas plants, stations and depots should be arranged on the upwind side of the year-round minimum frequency wind direction in towns and residential areas. In mountainous and hilly areas, it is advisable to avoid building plants, stations and depots in windy areas.
Article 3.0.3 The classification of oil and gas plants, stations and depots should be carried out in accordance with the provisions of Table 3.0.3 based on the total capacity of storage tanks for storing crude oil, liquefied petroleum gas and natural gas condensate. And shall comply with the following provisions:
1. When oil and gas plants, stations and depots are equipped with two or more types of storage tanks for crude oil and liquefied petroleum gas and natural gas condensate, the total capacity of the storage tanks shall be calculated separately and shall be determined according to the higher level;
2. For natural gas processing plants and compressor stations with a production scale greater than or equal to 100×10m/d, when the storage tank capacity is less than the total storage capacity of the third-level plants and stations, they shall still be classified as third-level plants and stations;
3. For natural gas processing plants and compressor stations with a production scale less than 100×10m/d and greater than or equal to 50×10m/d, when the storage capacity is less than the total storage capacity of the fourth-level plants and stations, they shall still be classified as fourth-level plants and stations; 4. Natural gas processing plants and compressor stations with a production scale less than 50X10°m2/d, as well as other stations of gas gathering and transmission projects of any production scale, shall still be fifth-level stations.
