DR AS 2419.1 – Objective

“The objective of the new AS 2419.1 is to specify minimum requirements for the design, installation and commissioning of fire hydrant systems which— a) will augment the efficient extinguishment of fire within the boundaries

of the site;

b) can be utilized to minimize fire spread within or between one property or building and another;

c) can be used by trained fire-fighting personnel; and

d) Have inlet an outlet connections suitable for use with the local fire brigade’s firefighting equipment.”



DR AS 2419.1 – Objective

“The objective of this edition is to incorporate changes that reflect current best practice, and to restructure, refine and expand the content o the Standard to clarify the intent of the normative provisions.” This has resulted in an increase in the number of informative appendices.





DR AS 2419.1 – Key Changes

“The changes in this revision include the following: (i) A restructure of the document and content to make it easier to use and

to improve its readability. (ii) Inclusion of informative appendices to clarify the intent of section(s) and clause(s). (iii) New technologies and industry best practices to enable competitive and cost-effective design and water conservation. (iv) previous Section 8, “Pipework and valves” split into two sections. (v) Acknowledgement of the life safety benefits of installed sprinkler systems.”



DR AS 2419.1 – Key Changes - Foreword

There is now an acknowledgement in the foreword of DR AS2419.1 that: “Fire hydrant systems need to be designed, installed and commissioned by a person who have acquired through training, qualification, experience, or a combination of these, the knowledge and skill enabling them to correctly perform the required tasks.” This is aligned with FPA Australia’s development of the national Fire Protection Accreditation Scheme (FPAS) and proposed design, installation and certify classes to complement the already launched test and inspect class of accreditation.



DR AS 2419.1 – Key Changes – Section 1 Definitions



The new standard includes 30 additional definitions to assist practitioners and approval

agencies.

Some examples include:

• Awning

• Balcony

• Break tank

• Block plan

• Boost

• Cabinet

• Classification

• Façade

• Fire brigade

• Fire hydrant attack/feed

• Fire load

• Fire main

• Floor area

• Flow, downstream

• Flow, Upstream

• Large Isolated Building

• Pressure, boost

• Pressure test (hydrostatic)

• Private water mains

• Pumpset

• Pumpset, fire hydrant

• Pumpset, jockey

• Pumpset, relay

• Reticulated water supply

• Room

• Roof

• Suction connection

• Water agency

• Water supply, infill

• Water supply, primary

• Water supply, supplementary

DR AS 2419.1 – Key Changes – Section 2 System Performance & Design • No fire brigade booster assembly installed –

External Feed hydrant pressure and flow requirements apply

• Fire brigade booster assembly installed -

External Attack hydrant pressure and flow requirements apply

+

Additional pressure and flow capacity when boosted

Internal Attack hydrant pressure and flow – different requirements



DR AS 2419.1 – Key Changes – Section 2 System Performance & Design Clause 2.2.8 Multiple firefighting systems

“Where an additional firefighting system, other than hose reels (e.g. wall-

wetting sprinklers, automatic fire sprinklers) draw from the same water source

or uses common pipework, the water source shall provide for the

simultaneous operation of the systems.”

This aligns with FPA Australia Technical Advisory Note TAN-01.



DR AS 2419.1 – Key Changes – Section 2 System Performance & Design Clause 2.3 Hydraulic Design parameters

“Residual pressure at each fire hydrant shall not be less than that specified in

Tables 2.6, 2.7, 2.8, 2.9 or 2.10”

No reference to 95% performance of residual pressure available to property

as per AS 2419.1-2005.

Information in relation to this is now in the “Informative Appendix T”.




Number of fire hydrants required to discharge simultaneously.

• New Table 2.1 provides basis for determining the number of hydrants required to

flow according to the number of fire compartment and building classifications. Risk

rationale applied.





DR AS 2419.1 – Key Changes – Section 2 System

Performance & Design Clause 2.3 Hydraulic Design parameters

Number of fire hydrants required to discharge

simultaneously.

• AS2419.1-2005 included 1 Table (Table 2.1). Now

multiple tables are proposed.

• New Table 2.2 – Class 2 to 9 Buildings (excluding

class 7a open deck carparks).

• Table now divided into:

• Non-sprinkler-protected buildings

• Sprinkler-protected buildings: <25m in

effective height

• Sprinkler-protected buildings: >25m in

effective height


• Table 2.3 – Class 7b or 8 buildings




• Table 2.4 – Class 7a Open deck carparks




• Table 2.5 – Open Yards




Hydrant Pressure and Flow

• No significant change to expected pressure and flows however, confusing Tables 2.2

and 2.3 from AS 2419.1-2005 now scrapped in favour of 5 separate tables as

follows:

• Table 2.6 – Feed hydrant performance

• Table 2.7 – Attack hydrant performance

• Table 2.8 – Fire brigade boosted performance

• Table 2.9 – Fixed on-site fire hydrant pumps

• Table 2.10 – Relay Pump(s)













DR AS 2419.1 – Key Changes – Section 3 Hydrant location & other related

provisions Clause 3.1 – General

• It is now nominated that location of fire hydrants must provide coverage to “all

portions of the building that are considered to be part of the floor area of the building

as defined by the National Construction Code series and, where required, all parts of

an open yard(s).”

• It is now noted that:

“Note 2. Fire hydrants may be above ground, with outlets suitable for connection

of a fire hose, or in ground, with connection suitable for attachment of a fire

brigade standpipe to which the fire hose may be connected.”




provisions Clause 3.2.2

Classification of hydrants as “external” now includes consideration of the following

parameters:

• Being external to enclosing walls

• Podium areas

• In relation to a building with no enclosing walls, in an area not covered by the roof

• Awnings, roof overhang or similar with effective depths of 3m




provisions




provisions Clause 3.2.3

A hydrant is now classified as “internal” if:

• It is within an area enclosed by walls or on a roof that is not considered to be a

podium

• Where there are no enclosing walls but under a roof

• Under an awning, balcony or horizontal floor projection




provisions Clause 3.2.4 – Classification of feed, attack and attack/feed fire hydrants

Considerations for classification of hydrants as feed, attack or attack/feed

• Is a fire brigade booster assembly installed?

• If a fire brigade booster assembly is installed, is the fire hydrant located downstream

of the fire brigade booster assembly?

• Is the hydrant within 20m or 10m of hardstand?

• What pressure and flow will be achieved?

Attack/feed is a new classification only applicable when hydrants are part of a system

where they may be used by the fire brigade as attack or feed hydrants.

Internal fire hydrants are attack fire hydrants.




provisions Clause 3.3 - Hardstand

Hardstand areas and vehicular approaches are proposed to meet certain criteria

including:

• Ability to withstand static and dynamic loads applied by attending fire brigade

pumping appliance(s)

appliance(s)

90/90/90 separating construction 2m either side, 3m above. Can be part of

the building or freestanding independent structure

• Greater than 3.5m and less than 10m
