PREFACE
This Standard was prepared by the Joint Standards Australia/Standards New Zealand
Committee FP-007, Fire Hose Reels, to supersede AS 2441—1988.
This Standard incorporates Amendment No. 1 (May 2009). The changes required by the
Amendment are indicated in the text by a marginal bar and amendment number against the
clause, note, table, figure or part thereof affected.
After consultation with stakeholders in both countries, Standards Australia and Standards
New Zealand decided to develop this Standard as an Australian Standard rather than an
Australian/New Zealand Standard.
The objective of this Standard is to provide users of fire hose reels with specific
requirements for their installation. It provides requirements for the protection of fire hose
reels in external situations, mounting requirements and clarifies the commissioning
procedure.
This edition includes the following changes:
(a) Additional terms defined for clarity.
(b) Flow rates clearly mentioned for different sizes.
(c) New requirements to protect the pipes from mechanical damage and low temperature.
This Standard will be referenced in the Building Code of Australia 2006 (BCA 2006)
thereby superseding AS 2441—1988, which will be withdrawn 12 months from the date of
publication of this Standard.
Notes to the text contain information and guidance. They are not an integral part of the
Standard.

4 DEFINITIONS
For the purpose of this Standard, the definitions below apply.
4.1 Class A fires
Fires that involve carbonaceous solids.
4.2 Hazard classes
4.2.1 High hazard
A class of hazard wherein the amount and type of combustibles present are such that fires
of large initial size may be expected. Typical high hazards include woodworking areas,
warehouses with high-piled storage in excess of 4.5 m, foam plastics processing and storage
which constitutes a Class A fire risk.
NOTE: Special consideration should be given to occupancies, which, because of their high-fuel
load, may more correctly be allocated a higher hazard class.

11 MOUNTING
The fire hose reel mounting shall comply with the following requirements:
(a) Surface-mounted fire hose reel assemblies shall be mounted so that the full diameter
of the drum, bearing the operating instructions, is facing the access point. For fire
hose reels of other types, the instructions shall be located so that relevant instructions
are visible when the fire hose reel is both in the stored and operational position.
NOTE: This is not necessarily to be taken as requiring the instructions to be on the outside of
any cabinet door.
(b) The fire hose reel assembly shall be suitably mounted at a spindle height of between
1400 mm and 2400 mm above floor level. The stop valve shall be mounted at
1000 ±100 mm above floor level. (See Figure 11.1.)
NOTE: The recommended mounting height of the centre of the fire hose reel is 1500 mm
above floor level.
(c) The stop valve assembly and instructions shall be visible and readily accessible when
the fire hose reel is ready for operation, and shall be not more than 2000 mm from the
spindle of the hose reel assembly. A clearance of not less than 100 mm shall be
provided around the stop valve handwheel or handle at any point where an operator
needs to place their hand.
(d) When the fire hose reel is surface-mounted or in a recess, cabinet or cavity, there
shall be a minimum radial clearance of 100 mm between the reel rim and any
obstruction to the sides, above and below that does not form part of the fire hose reel
assembly (see Figure 10.2). In the case of swing-type fire hose reels and those housed
in cavities, the above clearance applies when the fire hose reel is withdrawn from the
cabinet or cavity.
(e) Where a fire hose reel is fixed in a cabinet or recess, the hose guide shall protrude
beyond the recess when the hose is run out unless the requirements of Clause 12(b)
can be met without the hose guide protruding.
(f) Where a fire hose reel is mounted in a cabinet, the cabinet door(s) shall be openable
by single-handed operation of the latching mechanism.
(g) The fire hose reel and its mounting shall be firmly secured to the mounting surface in
accordance with the installation instructions provided with the fire hose reel in
accordance with AS/NZS 1221.
The structure on which the fire hose reel is mounted shall be capable of withstanding a
force of 1 kN.

Standards Australia Standards Australia develops Australian Standards® and other documents of public benefit and national interest. These Standards are developed through an open process of consultation and consensus, in which all interested parties are invited to participate. Through a Memorandum of Understanding with the Commonwealth Government, Standards Australia is recognized as Australia’s peak non-government national standards body. Standards Australia also supports excellence in design and innovation through the Australian Design Awards. For further information visit www.standards.org.au Australian Standards® Committees of experts from industry, governments, consumers and other relevant sectors prepare Australian Standards. The requirements or recommendations contained in published Standards are a consensus of the views of representative interests and also take account of comments received from other sources. They reflect the latest scientific and industry experience. Australian Standards are kept under continuous review after publication and are updated regularly to take account of changing technology. International Involvement Standards Australia is responsible for ensuring the Australian viewpoint is considered in the formulation of International Standards and that the latest international experience is incorporated in national Standards. This role is vital in assisting local industry to compete in international markets. Standards Australia represents Australia at both the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). Sales and Distribution Australian Standards®, Handbooks and other documents developed by Standards Australia are printed and distributed under license by SAI Global Limited.
