For information on
19、SI units reference should be made to BS 3763 “The International System of units (SI)”. The other parts of BS 5306 are: Part 0: Guide for selection of installed systems and other fire extinguishing equipment; Part 2: Sprinkler systems; Part 3: Code of practice for selection, installation and maintena
20、nce of portable fire extinguishers; Part 4: Specification for carbon dioxide systems; Part 5: Halon systems; Section 5.1: Halon 1301 total flooding systems; Section 5.2: Halon 1211 total flooding systems; Part 61): Foam systems; Part 72): Powder systems. The revision has been made in the light of cu
21、rrent progress in revising the CP 3: Chapter IV series, Code of basic data for the design of buildings: “precautions against fire”, and in conjunction with the preparation of the new range of standards covering particular items of equipment for fixed fire fighting installations in buildings. Some of
22、 the information previously found in this code is now to be published in these new standards, notably that on hose reels (BS 5274 in course of preparation). Since CP 402.101:1952 was prepared the practice of stowing long lengths of hose adjacent to landing valves has fallen out of favour, and this a
23、spect of the subject has therefore been omitted from the revised code. It is nowadays the practice for hose to be brought to the site by the fire brigade. It is recognized that recent projects such as shopping malls and town centre development and redevelopment schemes may be inaccessible to convent
24、ional fire appliances and may require special measures such as horizontal mains, but this code of practice does not give guidance on these special measures. Reference should be made to Fire Prevention Guide No. 1 “Fire precautions in town centre development” (published by HMSO). The fire authority s
25、hould also be consulted. In England and Wales, the provision of hydrant systems is largely a matter of voluntary good practice. In Scotland these are mandatory requirements in the Building Standards (Scotland) Regulations 1981 and 1982, and amendments thereof or additions thereto relating to the pro
26、vision of fire mains do not necessarily coincide with the requirements of this code of practice. 1)In preparation. 2)In preparation.

Hydrant systems, hose reels and foam inlets form only part, although an important part, of such facilities and it
30、should not be assumed their provision entirely obviates the need for portable fire extinguishers, other appliances or other fixed fire suppression systems. Wet and dry rising mains are intended for use by fire brigade or other trained personnel and provide a readily available means of delivering con
31、siderable quantities of water to extinguish or to prevent the spread of fire. Hose reels, although delivering smaller quantities of water, are capable of operation by untrained persons who may be in the vicinity when the fire is discovered, and thus can be more rapidly brought into action to tackle
32、a fire in its early stage of development. They may also be required for use by the fire brigade on arrival at the scene. They provide a continuous and easily controlled water jet and thus are generally more effective than portable fire extinguishers and less damaging than larger jets. Foam inlets ha
33、ve a more specialized role in dealing with oil fires and with fires involving electrical apparatus where a quantity of oil is involved. It should not be assumed that the provision of efficient hydrant systems and hose reels entirely obviates the need for portable fire extinguishers and other hand ap
34、pliances. On the contrary, these items may provide the best means of rapidly extinguishing a small fire before it has taken hold and before even a hose reel can be brought into action. Therefore consideration should always be given to supplementing hydrant systems and hose reels with hand appliances
35、. Moreover portable fire extinguishers may be required for certain special risks. Advice on such matters can always be obtained from the fire authorities, H.M. Factory Inspectorate and the fire insurance companies. In addition, reference should be made as necessary to other parts of this code of pra
36、ctice. It is essential that fire extinguishing equipment should be carefully maintained to ensure instant readiness when required. This routine is frequently tedious and liable to be overlooked or given insufficient attention by supervisors. It is however neglected at peril to the lives of occupants
37、 of the premises and at the risk of crippling financial loss. Its importance cannot be too highly emphasized. 1 Scope This code of practice covers good practice in matters affecting the planning, installation, testing and upkeep of fire hydrant systems including wet and dry rising mains, hose reels
38、and foam inlets on premises. Although statutory fire hydrants need to be considered when co-ordinating all fire fighting systems in a locality, the scope of this code of practice does not include them and if information is required concerning them reference should be made to the fire authority. 2 Re
39、ferences The titles of the British Standards publications referred to in this standard are listed on the inside back cover. 3 Definitions For the purposes of this standard the following definitions apply. They are the same as the terms adopted for general use in BS 4422-4 except that certain additio

Provision and siting of hydrants and risers 4 Fire hydrants, general 4.1 When they are considered to be necessary, private fire hydrants should be provided within the confines of the site af
48、ter consultation with the local water and fire authorities. Their installation should conform generally to this code of practice and also to any specific requirements of these authorities or the insurance company. 4.2 Fire hydrants should be positioned in such a way that the parking, loading and unl
49、oading of vehicles is unlikely to obstruct them, and in choosing locations for them regard should be paid to the availability of statutory hydrants in public thoroughfares nearby. 5 Fire hydrants, external 5.1 Where fire hydrants are to be installed, they should be included as part of a ring fire main system (see 9.7) and be positioned not more than 70 m from an entry to any building on the site and not more than 150 m apart. They should preferably be sited immediately adjacent to road-ways or hard-standing facilities provided for fire brig
