Fire Extinguisher Testing in Sydney: What the Law Actually Requires
If you have an extinguisher in a Sydney workplace, it needs a routine service every six months and a more thorough "extended" service at five years, carried out to AS 1851 and recorded on the tag. If the extinguisher appears on your building's fire safety schedule, that servicing is also what lets you sign off the measure on your Annual Fire Safety Statement each year, so a lapsed tag is not just a safety issue, it is a compliance one.
Below is what happens at each service, what you should be handed afterwards, and how to work out what you are actually responsible for.
Who has to do it
In New South Wales the obligation usually comes from two directions at once.
Work health and safety. Under the WHS Regulation, a person conducting a business or undertaking must maintain fire equipment in working order. An extinguisher that is empty, over-pressured or blocked in behind stock is not maintained.
Fire safety schedule and the AFSS. If your building has portable fire extinguishers listed as an essential fire safety measure, the owner must have them assessed each year and confirm on the statement that they have been maintained to the standard listed in the schedule, almost always AS 1851. That statement goes to Council and Fire and Rescue NSW. Our page on annual fire safety statements explains how the schedule and the statement fit together.
If you lease a tenancy, check the lease. Landlords commonly cover base building measures while tenants cover extinguishers inside the tenancy. Plenty of small businesses find out which one applies to them the week the statement is due.
Servicing intervals at a glance
AS 1851 sets different routines for different equipment. These are the intervals most Sydney sites deal with.
| Equipment | Routine service | Extended service | Typical notes |
|---|---|---|---|
| Portable extinguisher (dry chemical, foam, water, wet chemical) | 6 monthly | 5 yearly | Extended service involves discharging, internal inspection and refilling |
| CO2 extinguisher | 6 monthly | Cylinder pressure test on the gas cylinder schedule | Cylinders are tested and stamped, not simply refilled |
| Fire blanket | 6 monthly | Replace if used or damaged | Blankets are not repaired after use |
| Fire hose reel | 6 monthly | 5 yearly flow and pressure checks | Hose must run out fully and freely |
| Fire hydrant system | 6 monthly | Yearly and 5 yearly testing by a hydraulic contractor | Separate scope from portable equipment |
An extinguisher that has been discharged, even for ten seconds during a drill, comes out of service straight away and goes back for refilling. Stored pressure units do not reseal.
What a six-monthly service actually covers
It is quick, but it is not a glance. A technician should be:
- Checking the extinguisher is in its designated location, on its bracket or stand, and not sitting on the floor behind a pallet
- Confirming the location sign is in place and visible from the approach
- Checking the pressure gauge reads in the green, the pin and tamper seal are intact, and the hose and horn are clear
- Weighing or checking the unit against its charged weight where the type requires it
- Inverting and inspecting dry chemical units so the powder has not packed down
- Looking for corrosion, dents, damaged labels and a blocked or aged discharge hose
- Recording the work on the tag and in the maintenance record
At five years the unit is discharged and emptied, the cylinder is inspected internally, valves and o-rings are replaced as needed, and it is refilled and repressurised. CO2 units follow the cylinder testing regime instead, because they are pressure vessels.
What you should get afterwards
Three things, every time:
- A tag on each unit showing the service date, the standard, and the technician or company.
- A record or log book entry listing every asset, its location and its result. This is what an inspector or your certifier will ask to see, not the tags.
- A defect list naming anything that failed, what it needs, and whether the unit has been taken out of service.
If a service happens and you get nothing in writing, you have paid for a sticker. Keep the records for at least the life of your current statement, and preferably longer.
Do you have the right extinguishers in the right places?
Testing confirms an extinguisher works. It does not confirm it is the right one for the risk beside it. The common Sydney problems we see described are a kitchen with a dry chemical unit and no wet chemical for cooking oil, a switchboard with a water extinguisher near it, or a warehouse where travel distance to the nearest unit is far past what AS 2444 contemplates.
Worth checking at the same time as your service:
- Every extinguisher has a clear, unobstructed path and a sign visible from a distance
- The type suits the hazard: wet chemical for cooking oils, CO2 for live electrical, dry chemical as the general purpose unit
- Locations match what is shown on your evacuation diagrams
That last point catches people out. Extinguishers get moved during fit-outs and the diagrams on the wall stop matching the floor. Under AS 3745 the diagrams have to show current equipment locations, so if units have moved, your evacuation diagrams need updating too. If you are short on units, or need the right type for a particular hazard, we can help with fire extinguisher and equipment supply.
Getting it timed right
Work backwards from your Annual Fire Safety Statement due date. Many buildings run into trouble because extinguisher servicing sits on one calendar and the statement sits on another, and a unit falls out of date three weeks before sign-off.
A simple approach that works:
- Set the two six-monthly services so one lands roughly a month before the statement anniversary
- Diarise the five-yearly for each batch of units, because they will not all be the same age
- Fix defects immediately rather than letting them queue up to the next visit
- Keep the log, the diagrams and the emergency procedures in the same folder
If your site also needs written procedures for who does what during a fire, the emergency plans and response procedures side sits alongside the equipment side and is a separate obligation under the WHS Regulation.
FAQ
My extinguisher's gauge is in the green. Do I still need a service?
Yes. The gauge only tells you the unit holds pressure. It says nothing about packed powder, a perished hose, internal corrosion, or whether the unit is still the right type for the hazard next to it. The six-monthly interval is set by the standard, not by the gauge.
Can I just buy a new extinguisher instead of paying for the five-yearly service?
Sometimes that is the cheaper call, particularly for small dry chemical units. Ask for both numbers before you decide. Either way, a replacement unit still has to be recorded and tagged and still enters the six-monthly cycle from the day it goes on the wall.
Does one visit cover extinguishers, hose reels and hydrants?
Not always. Portable equipment and hose reels are commonly done together. Hydrant and sprinkler systems are a separate scope with their own testing regime and their own records, and larger sites usually need fire block plans showing isolation points and system layout for the brigade.
