4.2.6 Hose reels in open areas

When 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 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 fixing

Hose 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-fighting will not prevent the unimpeded use
of the hose reel.

4.3 Water supply for hose reels

4.3.1 General

The 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 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 respectively, 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 pumps

4.3.2.1 Where the water pressure in hose reel mains needs to be
boosted, the provision of an electrically driven pump is usually a
convenient 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.

4.3.2.3 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 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 = 105 N/m2 = 100 kPa.

BS 5306-1:2006

4.3.3 Connection for boosted supplies

Some 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 specified in BS EN 671-1:2001, Table 4.
The tank or tanks should be automatically supplied from a town’s main,
controlled by a ball valve of minimum diameter 50 mm.

4.3.4 Use of domestic water tanks

Tanks supplying water for domestic purposes should not be used as
suction tanks for hose reel installations 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 Security

The main stop valve controlling the water supply to the hose reels
should be secured fully open by 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 inlets

5.1 General
Oil 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-fighting and search and rescue operations,
might require foam inlets so that foam can be applied to a fire from
outside a building by means of a system of fixed piping and suitable
outlets. The fire authority should be consulted on this matter.

A foam inlet delivery pipe in a transformer chamber should be
electrically earthed in accordance with BS 7671 and BS 7430. Those
joints which do not provide electrical continuity should be bonded.

5.2 Capability of inlets and lines
Not more than three outlets, having an aggregate cross-sectional area of
not more than 3 200 mm2, should be supplied by one inlet and one line
of delivery pipe. Where there are more than three outlets, or the
aggregate cross-sectional area of the outlets appreciably exceeds
3 200 mm2, additional inlet(s) and delivery pipe(s) should be installed.
