Full title and description

AS 2419.1-2021 — Fire hydrant installations, Part 1: System design, installation and commissioning. This standard specifies requirements for the design, installation, commissioning and testing of on‑site fire hydrant installations used to protect buildings, structures, storage yards, marinas, wharves and plant. It defines system performance (flow and pressure), siting and coverage, equipment requirements, installation practice and commissioning tests to ensure hydrant systems are suitable for firefighting operations.

Abstract

AS 2419.1:2021 provides prescriptive and performance‑based requirements for fire hydrant systems intended to supply fire brigades and building occupants with charged hose lines. The document covers water supply considerations, hydraulic design, internal and external hydrant locations, riser and branch mains, fittings, valves and booster assemblies, and procedures for commissioning, flow and pressure testing, and maintenance handover. The 2021 edition updates previous requirements and consolidates guidance previously referenced in the National Construction Code.

Scope

Specifies requirements for design, installation, commissioning and testing of on‑site fire hydrant installations for a wide range of buildings and facilities, including guidance and limitations for building classes, maximum building heights and volumes, and special situations such as racked storage or multiple water supply sources. The standard applies to both internal and external hydrant arrangements and includes provisions for using reticulated (street) mains where appropriate. Appendices provide additional guidance for large volumes or special storage systems.

Key topics and requirements

• Design flow and pressure criteria for hydrant systems (required flow rates, residual pressures and design points).
• Hydrant siting and coverage rules for internal and external hydrants, including minimum/maximum distances to protected structures and access considerations for fire brigade vehicles.
• Water supply arrangements: on‑site supplies, reticulated mains, multiple supply sources and booster assemblies (including recommended booster siting near main entrances or access points).
• Piping, riser, valve, coupling and fitting specifications including Storz fitting considerations (see related Part 4 for Storz fittings guidance).
• Commissioning, flow testing and pressure testing procedures, acceptance criteria and documentation for handover to owners and authorities having jurisdiction.
• Maintenance and inspection intervals, marking and signage requirements to ensure system readiness for emergency use.

Typical use and users

Used by fire protection designers, consulting engineers, building services engineers, fire safety consultants, installing contractors, commissioning agents, building surveyors and authority having jurisdiction (AHJ) assessors. Also referenced by facility owners, asset managers and fire brigade personnel when verifying hydrant availability, access and performance. Compliance with AS 2419.1:2021 is often required for building approvals and inspections in Australia.

Related standards

AS 2419 series (other parts) — for example AS 2419.4 (Storz fittings) and related parts that cover specific fittings or components; AS 2419.2 where applicable (if present in the national series), and other Australian standards for sprinkler systems, fire detection and hydrant fittings. The standard is often used alongside the National Construction Code (NCC) and relevant plumbing/water supply standards such as AS/NZS 3500 for water services.

FAQ

Q: What is this standard?

A: AS 2419.1:2021 is the Australian Standard that sets out requirements for the design, installation and commissioning of on‑site fire hydrant installations used to support firefighting operations.

Q: What does it cover?

A: It covers design flows and pressures, siting and coverage for internal and external hydrants, piping and fittings, booster assembly siting and protection, commissioning and testing procedures, and maintenance and marking requirements. The standard includes normative clauses and informative appendices for special building types and larger installations.

Q: Who typically uses it?

A: Fire protection engineers, consulting engineers, installers, commissioning agents, building certifiers, facility owners and fire brigade personnel involved in specification, installation, testing and verification of hydrant systems.

Q: Is it current or superseded?

A: The 2021 edition (AS 2419.1:2021) is the current published edition (replacing earlier editions such as the 2017 edition). Users should confirm with Standards Australia or their AHJ for the most recent status and any amendments.

Q: Is it part of a series?

A: Yes — AS 2419.1 is part of the AS 2419 series addressing fire hydrant installations; other parts address specific components and fittings (for example, Part 4 covers Storz fittings). The series is intended to be used together where applicable.
