16、peThis part of BS 5306 gives recommendations for hose reels and foam inlets. It covers good practice in matters affecting the design, installation, testing and maintenance of such systems. It does not give requirements for the hose reels themselves, which are specified in BS EN 671.This part of BS 5
17、306 does not cover wet and dry fire mains, automatic foam systems and portable fire-fighting equipment. These systems are covered in BS 9990, BS 5306-3, BS 5306-8 and BS EN 3-7.2 Normative referencesThe following referenced documents are indispensable for the application of this document. For dated

26、 and feeds to individual hose reels should be not less than 20 mm nominal bore.4.1.3 Pipes should be made of one of the following:a) steel in accordance with BS 1387;b) copper in accordance with BS EN 1057, with fittings in accordance with BS EN 1254-1 or BS EN 1254-2;c) plastics which are satisfact
27、ory to the water supply undertaking for this application, provided the pipework is protected from damage, by fire or otherwise, by location in a low risk area such as underground or in a service duct of brick, concrete or equivalent construction.4.1.4 The water supply to hose reels should normally b
28、e kept entirely independent from other water supplies within the building including those for other fire-fighting systems. In certain special circumstances the supply to hose reels may be taken from the supply provided for a sprinkler system (see BS EN 12845, BS 5306-2 and the Fire Protection Associ
29、ation publication LPC rules for automatic sprinkler installations incorporating BS EN 12845 1).4.1.5 When the likely routes for the hose are tortuous, the length and size of hose on the reel should be limited, and the siting and provision of reels should be reviewed with these limitations in mind. C
30、onsideration should also be given to the physical attributes of the individuals who are expected to use the equipment.4.1.6 It is essential that pressures and flows should at all times be adequate to serve the designed number of hose reels likely to be used. This is irrespective of the source of wat
31、er supply. BSI 2006 3BS 5306-1:20064.2 Provision and siting4.2.1 ProvisionHose reels, where installed, should be provided to cover all risk areas.4.2.2 SitingHose reels should be sited in prominent and accessible positions at each floor level adjacent to exits in corridors on exit routes, in such a
32、way that the nozzle of the hose can be taken into every room and within 6 m of each part of a room, having regard to any obstruction. Where heavy furniture or equipment might be introduced into a room, the hose and nozzle should be capable additionally of directing a jet into the back of any recess
33、formed.In exceptional circumstances it might be desirable to site hose reels in such a way that if a fire prevents access to one hose reel site, the fire can be attacked from another hose reel in the vicinity.It is essential that the hose reels remain unobstructed and that they are available for use
34、 at all times.In buildings that have large open floor areas such as warehouses, the stacking arrangements should provide for unobstructed access to the hose reel. It might also be considered necessary to provide guard rails around the hose reel position to prevent stacking taking place immediately a
35、djacent, care being taken that the guard rails do not obstruct the operation of the hose.Where stacking is taking place, notices indicating the hose reel positions should be sited at high level.These notices could be situated over the main avenues, subject to directional arrows being provided.4.2.3
36、Frost protectionHose reels and their water supply systems should be afforded all possible protection against frost.4.2.4 Electrical earthingElectrical earthing should be in accordance with BS 7671 and BS 7430.4.2.5 Installation of hose reels4.2.5.1 Hose reels in recessesPreferably hose reels should
37、be installed in recesses so that they do not form obstructions on a route of escape. The details of installation will vary considerably owing to the wide variation of types of hose reel and their size.4.2.5.2 Recess doorsAny doors provided for hose reel recesses should be in accordance with BS EN 67
38、1.BS 5306-1:20064 BSI 20064.2.6 Hose reels in open areasWhen installed on open floor areas it might be necessary to position hose reels above head height but in these cases the nozzle retainer, the hose guide and the inlet valve should be fitted at about 900 mm above floor level. NOTE It might also
39、be desirable to provide an anti-over-run device to prevent the hose from becoming entangled when run out.4.2.7 Importance of firm fixingHose reel brackets should be firmly fixed to the wall so that casual knocks received during normal use of the building and the stresses incurred during use for fire
40、-fighting will not prevent the unimpeded use of the hose reel.4.3 Water supply for hose reels4.3.1 GeneralThe water flow rate at the most hydraulically remote hose reel should be not less than the relevant values specified in BS EN 671-1:2001, Table 4 and BS EN 671-2:2001, Table 4, and the pressure
41、should be sufficient to meet the range requirements of BS EN 671-1 when it is in use simultaneously with the nearest adjacent hose reel.NOTE The method given in BS EN 671-1 gives a test running pressure, at the reel inlet, of 4 bar1)or 5 bar, for the maximum lengths of 25 mm and 19 mm hose respectiv
42、ely, with a requirement that the range of a jet be not less than 6 m. The range of a spray on a jet/spray nozzle may be less than this value.4.3.2 Booster pumps4.3.2.1 Where the water pressure in hose reel mains needs to be boosted, the provision of an electrically driven pump is usually a convenien
43、t method. A duplicate standby pump should also be provided.4.3.2.2 Both motors and pumps should be sited in fire protected positions and the electrical supply to them should be by an exclusive circuit with the cables following a route of negligible fire risk or be provided with adequate protection.4
44、.3.2.3 The booster pumps system should come into operation automatically on a drop in pressure or a flow of water. Both pumps should be automatically primed at all times.4.3.2.4 All pumps should also be capable of being started or stopped manually. The standby pump should be so arranged that it will
45、 operate automatically on a failure for any reason of the duty pump.4.3.2.5 An audible and visual alarm should be provided at an agreed position to indicate that the equipment and the pumping plant have operated.1)1 bar = 105N/m2= 100 kPa. BSI 2006 5BS 5306-1:20064.3.3 Connection for boosted supplie
46、sSome water undertakings do not permit a booster pump to be connected directly into a supply main. In such cases the installation should be fed from a suction tank or inter-connected tanks having a minimum capacity capable of supporting operation of the hose reel for 45 min at the minimum flow rate
47、specified in BS EN 671-1:2001, Table 4. The tank or tanks should be automatically supplied from a towns main, controlled by a ball valve of minimum diameter 50 mm.4.3.4 Use of domestic water tanksTanks supplying water for domestic purposes should not be used as suction tanks for hose reel installati
48、ons unless arrangements have been made for these domestic supplies to be drawn off in such a manner that the requisite reserve of water for the hose reel installation is always preserved.4.3.5 SecurityThe main stop valve controlling the water supply to the hose reels should be secured fully open by
49、a suitable device such as a padlocked chain or strap. Hose reels should also be protected against interference and attack by thieves and vandals as far as it is possible to do so without adversely affecting operational capability. This should be done in accordance with Annex A.5 Foam inlets5.1 GeneralOil risks situated at or below ground level, e.g. oil-fired boiler rooms, oil storage tank chambers or transformer chambers, where they might not be directly accessible for fire-fighti
