Chapter I General Provisions
Article 1.0.1 For the purpose of reasonably distributing
fire extinguishers, effectively suppressing initial fires in industrial and civil buildings, minimizing fire damage and protecting the safety of persons and property, the Code is hereby formulated.
Article 1.0.2 The Code applies to new, extended and renovated industrial and civil buildings where combustibles are manufactured, used or stored. The Code does not apply to factory buildings (warehouses) where gunpowder, explosives, ammunition, priming systems and fireworks are manufactured and stored, and nine-and-less-storey ordinary dwelling houses.
Article 1.0.3 The type, size, number and location of fire extinguishers distributed in a building shall be deemed as the content of building design, and shall be marked on the project designing drawings.
Article 1.0.4 In addition to the provisions of the Code,
the design of distribution of fire extinguishers in a building shall also meet the requirements of relevant current standards and codes of China.
Chapter II Types of Hazards in Fire Extinguisher Distribution Areas and Ratings of Fire Extinguishers
Article 2.0.1 The types of hazards in fire extinguisher distribution areas in industrial buildings shall be determined according to such factors as the fire harzards of the goods manufactured, used and stored, the amount of combustibles contained, the speed of fire spread and the degree of difficulty in fire suppression in case of fire, etc. There are three types of hazards:
1) Severe hazard: Areas in which high fire hazards exist,
combustibles are contained in large amounts, and fire may spread quickly or is liable to cause heavy damage in case of fire;
2) Moderate hazard: Areas in which relatively high fire
azards exist, combustibles are contained in relatively large amounts, and fire may spread relatively quickly in case of fire; and
3) Light hazard: Areas in which relatively low fire hazards exist, combustibles are contained in relatively small amounts, and fire may spread relatively slowly in case of fire.
For examples of types of hazards in fire extinguisher dis-tribution areas in industrial buildings see Appendix B of the Code.
Article 2.0.2 The types of hazards in fire extinguisher
distribution areas in civil buildings shall be determined according to such factors as the nature of occupancy, the fire hazards present, the amount of combustibles contained, the speed of fire spread and the degree of difficulty in fire suppression in case of fire, etc. There are three types of hazards:
1) Sever hazard: Areas in which functions are complicated, power and fire are used in large quantities, equipment is valuable, high fire hazards exist, combustibles are contained in large amounts, and fire may spread quickly or is liable to cause heavy damage in case of fire;
2) Moderate hazard: Areas in which power and fire are used in relatively large quantities, relatively high fire hazards exist, combustibles are contained in relatively large amounts, and fire may spread relatively quickly in case of fire; and
3) Light hazard: Areas in which power and fire are used in relatively small quantities, relatively low fire hazards exist, combustibles are contained in relatively small amounts, and fire may spread relatively slowly in case of fire.
For examples of types of hazards in fire extinguisher distribution areas in civil building see Appendix C of the Code.
Article 2.0.3 Fires shall be classified according to the kinds of materials involved and their characteristics of combustion into the following:
1) Class A fires: Refer to fires in carbonaceous solid state combustibles, such as wood, cotton, wool,flax and paper, etc.;
2) Class B fires: Refer to the fires in kinds A, B and C
liquids, such as gasoline, kerosene, diesel oil, methanol, ether and acetone, etc.;
3) Class C fires: Refer to the fires in combustible gases,such as coal gas, natural gas, methane, propane, acetylene and hydrogen, etc.;
4) Class D fires: Refer to the fires in combustible metals, such as potassium, sodium, magnesium, titanium, zirconium, lithinium and aluminium-magnesium alloy, etc.; and
5) Electrified fires: Refer to the fires in electrified objects.
Article 2.0.4 The expression of rating of a fire extinguisher shall consist of a number and a letter. The number shall denote the magnitude of rating, while the letter (A or B) shall denote the unit of rating and the class of fire for which it is rated.
Chapter III Selection of Fire Extinguishers
Article 3.0.1 Fire extinguishers shall be selected according to the following factors:
1) The class of fire expected in the fire extinguisher distribution area;
2) Effectiveness of fire suppression;
3) Degree of contamination of goods to be protected;
4) Ambient temperature in the places where fire extinguishers are mounted; and
5) Capability of the people who will use the extinguisher.
Article 3.0.2 Selection of types of fire extinguishers shall meet the following stipulations:
1) For class A fires, water, foam, ammonium phosphate base dry chemical or halogenated hydrocarbon fire extinguishers shall be selected;
2) For class B fires, dry chemical, foam, halogenated hydrocarbon or carbon dioxide fire extinguishers shall be selected;
3) For class C fires, dry chemical, halogenated hydrocarbon or carbon dioxide fire extinguishers shall be selected;
4) For electrified fires, halogenated hydrocarbon, carbon dioxide or dry chemical fire extinguishers shall be selected;
5) For class A, class B, class C and electrified fires, ammonium phosphate base dry chemical or halogenated hydrocarbon fire extinguishers shall be selected; and
6) For class D fires, the selection of fire extinguishers and equipment shall be made by the designing organization through consultations with local public security and fire protection supervisory departments.
Article 3.0.3 When fire extinguishers of the same type are selected for use in one fire extinguisher distribution area, it is advisable to select fire extinguishers with the same method of operation.
Article 3.0.4 When two or more types of fire extinguishers are selected for use in one fire extinguisher distributionarea, fire extinguishers with compatible extinguishing agentsshall be used. For incompatible extinguishing agents see Appendix D of the Code.
Article 3.0.5 It is prohibited to distribute Halon extinguishers in where are unnecessary to use, ABC powder extinguishers and AFFF extinguishers, etc.,shall be distributed.
The determination for where is unnecessary to use Halon extinguishers should be according to the regulations issued by NFPB and NEPA.
The examples for where is unnecessary to use Halon extinguishers, see Appendix G.
