Take a look at the fire extinguisher nearest to you. Hanging from the handle or attached to the cylinder, there's a small tag. Most people walk past it every single day without a second thought. But that little tag tells you everything about your extinguisher's service history, and for Australian businesses, reading it correctly matters for compliance.

Under Australian Standard AS 1851-2012, all portable fire extinguishers must carry a service tag as part of their routine maintenance record. Knowing how to read a fire extinguisher tag is a straightforward skill, and this guide walks you through exactly what to look for.

Why Tags Matter for WHS Compliance

Fire extinguisher tags aren't just an administrative formality. They're a legal record.

AS 1851-2012 requires each extinguisher to carry a permanently marked tag documenting when the last service was performed and when the next one is due. The tag must be securely attached with a minimum retention force of 200 N, which means simple cable-ties don't meet the standard. 

From a workplace safety standpoint, the stakes are tangible. In some Australian jurisdictions, a single defective or out-of-date extinguisher can attract on-the-spot fines. According to the SafeWork NSW penalty schedule, fines can reach up to $3,600 per unit under 2025 WHS regulations. Keeping tags current and legible is one of the simplest ways to stay prepared for an audit.

The Anatomy of an AS 1851 Service Tag

Standard Australian service tags are typically yellow aluminium and follow a consistent layout. Once you know the format, reading them takes seconds.

The month and year grid

The tag displays a grid with months listed across the top and years running down the side. When a qualified technician completes a service, they punch a hole or stamp through the box corresponding to the month and year the work was performed. This creates a permanent, tamper-evident record of your extinguisher's service history.

Once all the date boxes are filled (roughly after 12 months of inspections), the technician attaches a new service tag and carries the most recent 12 months of records forward.

Service level numbers explained

Alongside the date punch, the technician marks the level of service completed. According to Firewize's technical guidance on date stamps, the service levels are

• Level 1: Six-monthly routine inspection.
• Level 2: Annual inspection, more comprehensive than Level 1.
• Level 3: Internal inspection of the extinguisher cylinder.
• Level 4: Five-yearly hydrostatic pressure test and recharge.
• Level 5: Discharge test, typically combined with other service levels.

Each number gives you an immediate picture of what was done and when.

Anti-tamper seals

Many service companies also attach colour-coded anti-tamper seals to the extinguisher pin or handle. The colour rotates with each service visit, so facility managers and auditors can see at a glance that all units on a site were serviced in the same period. 

Checking Your Extinguisher in Under a Minute

You don't need to be a technician to perform a basic tag check. Here's what to look for:

1. Locate the tag. It should be attached to the handle or body of the extinguisher.
2. Find the most recent punch or stamp. Check the month and year. Is it within the last six months?
3. Check the service level number. A "1" means a Level 1 six-monthly inspection was completed.
4. Look at the cylinder body. A manufacture date is stamped directly onto the cylinder. Under AS 2337.1 and the AS 1851 service schedule, extinguishers older than 10 years, or those without a pressure test in the past five years, must be pressure tested or replaced.
5. Assess the tag condition. Is it legible, firmly attached, and undamaged?

Under AS 1851 Table 1.16.2, inspections need to occur within one month either side of the due date to remain compliant. So if your last Level 1 inspection was in January, the next service needs to happen no later than the end of August.

What to Do If the Tag Is Missing or Illegible

An extinguisher without a legible, compliant tag is considered non-compliant until a full annual service is carried out. The service history can't be reconstructed from memory or assumption.

If you find extinguishers on your site without tags, contact a qualified technician promptly. They'll complete the required service, fit a compliant aluminium service tag, and issue the appropriate documentation. AS 1851 recommends retaining service records for seven years, which is the higher benchmark compared to some state-based requirements (Queensland's Building Fire Safety Regulation 2008, for instance, specifies two years as a minimum).

Staying on Schedule Throughout the Year

For most businesses, six-monthly extinguisher servicing covers the regular Level 1 inspections, with the annual Level 2 typically combined with one of those visits. Every five years, a Level 4 pressure test is required, involving a full recharge of the extinguisher agent.

Only technicians holding the relevant accreditation (units CPPFES2020 and CPPFES2026, or FPA Australia FPAS accreditation) are authorised to service extinguishers and complete the formal tag record.

It's also worth ensuring your team knows how to actually use the equipment. According to a Fire & Safety Australia survey, fewer than 50% of Australians feel confident using an extinguisher, and only 13% can identify the different extinguisher types. A current service tag matters, but confident people behind the equipment matter just as much. Our First Line of Defence fire safety training course is a practical one-hour on-site session that addresses exactly that. You can also browse our full range of compliant portable fire extinguishers if your existing equipment needs replacing.

A Small Tag with a Big Job

Reading a fire extinguisher tag doesn't require specialist knowledge. A few seconds of attention tells you when your equipment was last inspected, what service was performed, and when the next one is due. For anyone managing fire safety compliance, it's one of the easiest checks to build into a regular routine.

Frequently Asked Questions

How often should a fire extinguisher be serviced in Australia?

Portable fire extinguishers require a Level 1 inspection every six months and a more comprehensive Level 2 annual inspection, in accordance with AS 1851-2012. Every five years, a Level 4 hydrostatic pressure test and recharge is also required. Your qualified technician will keep your service tag up to date and advise when each interval is approaching.

What do the service level numbers on a tag mean?

The numbers indicate the type of service completed at that visit. Level 1 is the six-monthly routine inspection, Level 2 is the annual inspection, Level 3 is an internal cylinder inspection, Level 4 is the five-yearly pressure test and recharge, and Level 5 is a discharge test. Each number is marked alongside the date the service was performed, so the tag builds a clear service history over time.

Do I have to replace the tag every year?

Not necessarily. A tag is replaced when all the date boxes have been filled, which typically takes around 12 months of regular inspections. When the technician fits a new tag, they carry forward the most recent 12 months of records from the old one, so there's no gap in your service history.

Who is authorised to punch or stamp a fire extinguisher tag?

Only qualified technicians holding units CPPFES2020 and CPPFES2026, or those with FPA Australia FPAS accreditation, are authorised to service extinguishers and complete the tag record. Tags completed by unqualified personnel do not meet AS 1851 requirements and render the extinguisher non-compliant.

Does a home fire extinguisher need a service tag?

AS 1851-2012 applies primarily to commercial and industrial premises, so the formal tag requirements may not legally apply to a residential extinguisher purchased for personal use. That said, regular servicing is still recommended to ensure your home equipment will function reliably if you ever need it. A periodic inspection by a qualified technician gives you confidence that everything is in working order.

If you manage a commercial building, strata complex, or industrial premises in Australia, chances are you have fire doors on site. But what exactly makes a door a fire safety door, and why does the distinction matter for building compliance?

This guide breaks it all down, from how a fire safety door works through to signage requirements, inspection schedules, and who is authorised to certify one.

How a Fire Safety Door Works

A fire safety door is a purpose-built doorset rated to resist the spread of fire and smoke for a defined period. Unlike a standard interior door, every component is specifically tested together as a system. That includes the door leaf (the panel itself), the frame, the seals, self-closing hardware, and any glazed panels.

The door leaf is typically constructed from fire-resistant materials such as treated timber, steel, or a composite core. Intumescent seals run around the edge of the leaf and expand when exposed to heat, sealing the gap between the door and frame to block the passage of smoke and flames. Self-closing mechanisms ensure the door returns to its closed position automatically, which is central to how the system performs under the requirements of the National Construction Code.

Smoke doors operate on a similar principle but are tested to resist smoke rather than fire itself. They are commonly installed in stairwells, corridors, and other paths of travel where smoke control is the priority.

Australian Standards and NCC Requirements

AS 1905.1: construction standards

Under NCC 2022 Volume 1, Specification 12, all required fire doors must comply with AS 1905.1-2015, which covers the construction of fire-resistant doorsets. This standard sets out exactly how a doorset must be built and tested to achieve a Fire Resistance Level (FRL) rating.

Each compliant doorset is required to carry a metal identification tag, showing the test report number, the FRL rating, the manufacturer, and the year of construction (per AS 1905.1, Clause 4.5). This tag is what confirms the door is a certified product, not simply a door that looks the part.

AS 1851: inspection and maintenance schedules

Having a compliant fire door installed is only part of the equation. Routine testing and inspections are governed by AS 1851-2012 (Section 17), which requires:

• An operational test every 3 months, checking that the door closes and latches correctly.
• A detailed inspection every 12 months, covering seals, hardware, frame condition, clearances, and signage.

These inspections need to be recorded in a log. If your building requires an Annual Essential Services report, your fire door records will form part of that documentation. Our team provides fire door testing in Perth and can keep your building on schedule and compliant.

Mandatory Fire Safety Door Signage

Signage is a compliance requirement, not a suggestion. The wording, placement, and format of fire safety door signs are set out in NCC Volume 1, Part D2.23.

The required wording depends on the door's function:

• Self-closing fire doors must display: FIRE SAFETY DOOR – DO NOT OBSTRUCT – DO NOT KEEP OPEN
• Doors from fire-isolated exits must display: FIRE SAFETY DOOR – DO NOT OBSTRUCT

The lettering must be legible and placed on both sides of the door where required. 

Fire safety door signage that is missing, damaged, or showing incorrect wording is a common audit finding. If you need help with correct installation, our fire equipment sign installation guide covers what's required.

Fire Safety Door Accreditation – Who Can Install or Sign Off?

This is where things vary across Australia, and it pays to understand your state's requirements.

Western Australia has no dedicated fire door licence class. Installation must be carried out by a registered builder or under the supervision of a qualified person. Certification is generally provided by a building surveyor or an FPAS-accredited Fire Safety Assessor through the FPA Australia programme.

Queensland has specific QBCC Passive Fire Protection licence classes that cover both installation and certification of fire doors, so you'll need to confirm the credentials of anyone carrying out this work.

New South Wales updated its framework in February 2025. Installation and maintenance can now be carried out by non-accredited persons, but the Annual Fire Safety Statement must still be signed off by an accredited Fire Safety Practitioner.

If you're unsure about the requirements for your premises, Fullworks Fire Safety offers free fire safety surveys to help you identify what's in place and what may need attention.

What We See Going Wrong with Fire Doors in WA

Fire door compliance is an area where small issues can go unnoticed until an audit or insurance renewal brings them to light. A 2024 DMIRS audit of WA apartment buildings found that a significant proportion of buildings had fire doors that failed the closure test, meaning the door did not fully close and latch from an open position.

Common issues we encounter include:

• Doors propped open or held by wedges, disabling the self-closing function.
• Intumescent seals that have been painted over or are missing altogether.
• Incorrect or absent fire safety door signage.
• Modifications to the door leaf (holes drilled, hardware changed) that void the original certification.
• No record of inspections being carried out.

If your building hasn't had a fire door servicing check recently, it's worth scheduling one before your next Essential Services inspection or insurance renewal. A fire safety survey is a good starting point if you're not sure where your building currently stands.

Frequently Asked Questions

What's the difference between a fire door and a fire safety door?

In Australian buildings, the terms are generally used interchangeably. Technically, a "fire safety door" is the term used in the NCC and on required signage, while "fire door" is more commonly used in everyday conversation and trade. Both refer to a doorset that has been tested and certified to resist fire and smoke for a rated period. The key is that the door is a certified system, not just a solid or heavy door.

Do all fire safety doors in Australia need the "Do Not Obstruct" sign?

Yes. Under NCC Part D2.23, all fire safety doors must display approved signage. The exact wording depends on the door type. Self-closing doors within a building require both "DO NOT OBSTRUCT" and "DO NOT KEEP OPEN," while doors from fire-isolated exits require "DO NOT OBSTRUCT" only. Missing or incorrect signage is a compliance failure.

How often must a fire safety door be inspected under AS 1851?

AS 1851-2012 requires an operational test every 3 months and a detailed inspection every 12 months. Both must be documented. Buildings subject to Essential Services reporting will need these records available for sign-off.

Who is qualified to certify or tag a fire safety door in Western Australia?

In WA, there is no dedicated fire door licence. Certification is typically carried out by a registered building surveyor or an FPAS-accredited Fire Safety Assessor under the FPA Australia programme. Always confirm credentials before accepting a certification.

Can I paint, drill, or modify a fire safety door leaf?

No. Any modification to the door leaf, frame, or hardware, including painting over seals, drilling holes, or fitting additional hardware not covered in the original test report, can void the door's FRL certification. If modifications are needed, you'll need to consult the original manufacturer or a qualified assessor before proceeding.
