Fire Extinguisher Requirements for Construction Sites in Queensland

Construction sites are among the highest fire-risk workplaces in Australia. Flammable materials, temporary electrical installations, welding and cutting work, fuel storage, and a constantly changing site layout create hazards that don’t exist in a finished building. The fire safety rules that apply during construction are different from those that apply once a building is occupied — and many builders get caught out by not knowing which standard applies at which stage.

This guide covers exactly what Queensland law requires: how many extinguishers you need, what types, where to place them, when hydrants become mandatory, and who is legally responsible if something goes wrong.

The Legal Framework — What Governs Construction Site Fire Safety in Queensland

Fire safety on construction sites is governed by two overlapping frameworks depending on the stage of the project:

During construction: The National Construction Code (NCC) / Building Code of Australia (BCA), specifically Section E1.9 (“Fire precautions during construction”), sets out the minimum fire safety requirements while a building is being built. This applies from the moment construction begins until the building is occupied or a certificate of occupancy is issued.

Once occupied: The Building Fire Safety Regulation 2008 (Qld) and AS 1851-2012 take over. At this point the building owner or body corporate becomes the responsible party and must maintain all fire protection equipment through a licensed technician on a 6-monthly schedule.

The Australian Standards that underpin both phases are:

• AS 2444-2001 — Portable fire extinguishers and fire blankets: selection and location
• AS 1851-2012 — Routine service of fire protection systems and equipment
• AS 1841 — Portable fire extinguishers: general requirements

How Many Fire Extinguishers Are Required on a Construction Site?

BCA Section E1.9 sets the baseline requirement: at least one fire extinguisher suitable for Class A, B, C and electrical fires must be provided on every storey, adjacent to each required exit or temporary stairway or exit.

In practice, a single extinguisher per storey per exit is only the legal minimum. AS 2444 provides the practical placement rules:

On a large construction site, this typically means multiple extinguishers per floor. A floor plate of 30 × 40 metres (1,200 sqm) with significant Class A combustibles present — as most construction sites are — would need extinguishers positioned so that no point on the floor is more than 15 metres from one.

Higher-risk zones — fuel storage areas, generator bays, cutting and grinding stations — require their own dedicated extinguishers regardless of the general placement grid.

What Types of Fire Extinguishers Are Required on a Construction Site?

The BCA requires extinguishers suitable for Class A, B, C and electrical fires. In practice, this means an ABE-rated dry powder extinguisher is the standard choice for most construction sites, as a single ABE unit covers:

• Class A: Ordinary combustibles — wood, paper, textiles, some plastics
• Class B: Flammable liquids — petrol, diesel, solvents, paints
• Class E: Energised electrical equipment — switchboards, power tools, generators

ABE dry powder does not cover Class F fires (cooking oils) — but these are rarely present on construction sites. If your site has a functioning site kitchen or commercial cooking equipment, a wet chemical extinguisher should be added in that area.

Placement Rules Under AS 2444

Placement is just as important as having the right type. An extinguisher mounted in a storeroom, behind equipment, or above head height is effectively useless in an emergency. AS 2444 specifies the following mounting requirements:

• Handle height: The top of the handle must be no higher than 1,200mm from the floor — within easy reach for most adults
• Base height: The bottom of the extinguisher must be at least 100mm from the floor — keeps it off the ground and protected from water/debris
• Clearance: A minimum of 1,000mm of clearance in front of each extinguisher — must be accessible without moving equipment
• Signage: Each extinguisher must have a compliant location sign at 2,000mm height, visible from 20 metres, with white symbols on a red background
• Visibility: Must be clearly visible from the normal approach path — never inside cupboards or behind doors

On construction sites, extinguisher locations need to be reassessed as the site evolves. If floor layouts change, new high-risk areas are created, or access routes are altered, placement must be updated to maintain the correct travel distances.

When Do Fire Hydrants and Hose Reels Become Mandatory?

BCA Section E1.9 introduces a critical threshold: once a building under construction reaches an effective height of 12 metres, the requirements escalate significantly.

At the 12-metre threshold, the following become mandatory:

• Fire hydrants must be operational on every storey covered by the roof or floor structure above, except the two uppermost storeys
• Fire hose reels must be installed and operational at the same intervals
• Any required booster connections must be installed and accessible to the fire brigade

This threshold catches many multi-storey residential and commercial builds. A four-storey building will typically hit 12 metres by level 2 or 3 — well before the building is anywhere near complete. The builder must ensure the hydrant and hose reel infrastructure is installed and operational at that point, even if the rest of the building is still a skeleton.

The obligation falls on the builder, and fire authorities do inspect multi-storey construction sites to verify compliance. Failure to have operational hydrants and hose reels above 12 metres is a serious non-compliance that can result in a stop-work notice.

Servicing and Inspection Requirements

Construction site fire extinguishers are not exempt from AS 1851 servicing requirements. Under AS 1851-2012, all portable fire extinguishers must be inspected and serviced:

• Every 6 months — routine inspection, testing, tagging, and compliance report
• Every 5 years — full pressure test (hydrostatic) and internal overhaul

In Queensland, this service must be carried out by a QBCC-licensed fire protection technician. A QBCC licence is not the same as a general trade licence — it is specific to fire protection work and cannot be substituted by an electrician, plumber, or other tradesperson.

For construction projects shorter than 6 months, extinguishers should be within their current 6-monthly service date when installed and checked before placement. For longer projects, a 6-monthly service must occur during the construction period.

Essential Fire Protection holds QBCC Licence 1171614 and FPAA Licence IT47941, covering all fire protection work in South East Queensland. Our technicians service construction sites across Brisbane, the Gold Coast, and the Sunshine Coast — including large multi-storey builds.

Who Is Legally Responsible for Fire Safety on a Construction Site?

The builder or principal contractor is legally responsible for fire safety compliance during construction under BCA Section E1.9. This is not a shared responsibility with subcontractors — the principal contractor owns the obligation and cannot delegate it away in a subcontract.

Key implications:

• If a subcontractor removes an extinguisher without replacing it, the builder is still the liable party if a fire inspector attends
• If the site is shut down or work pauses, fire extinguishers must remain in place and in-date
• The builder must maintain records of extinguisher services — service tags alone are not sufficient; a written compliance report from a licensed technician is required

Once the building is occupied or a certificate of occupancy is issued, the responsibility transfers to the building owner, body corporate, or occupier under the Building Fire Safety Regulation 2008 (Qld). At that point, the ongoing obligation is the 6-monthly AS 1851 service regime.

Transitioning to Occupancy — Setting Up Ongoing Compliance

One of the most common compliance gaps we see at Essential Fire Protection is a building that was maintained to BCA E1.9 during construction, but has no ongoing compliance plan in place at practical completion.

At handover, the building owner needs:

1. A full fire protection equipment register — every extinguisher, hose reel, exit light, and hydrant, with location and last service date
2. A 6-monthly service booking with a licensed technician — ideally on an automatic reminder system so nothing lapses
3. A logbook retained on-site (AS 1851 requires records to be kept for at least 7 years)
4. Signage and mounting reviewed to AS 2444 standards for the occupied use — not just the construction standard

Essential Fire Protection can conduct a practical completion fire safety check, establish the ongoing service schedule, and take over compliance management from day one of occupation. This is particularly valuable for strata developments, commercial buildings, and body corporate properties where the compliance responsibility distributes across multiple parties.

For pricing on the ongoing service: from $120 for up to 5 extinguishers, and $12 per additional extinguisher — no call-out fee across Greater Brisbane, the Gold Coast, and Sunshine Coast. For large sites and multi-property portfolios, we quote on the full scope. See our full fire extinguisher testing cost guide for a detailed breakdown of what’s included.
