How often must fire hose reels be serviced?
Fire hose reels are Section 9 of AS 1851-2012, with six-monthly and yearly routines. The six-monthly covers access, signage, hose condition, nozzle, and that the reel operates and the valve seals. The yearly adds a flow and pressure check to confirm the reel actually delivers what it should at the nozzle.
Installation is to AS 2441 and the reel itself is manufactured to AS/NZS 1221. Hose that fails the standard's condition criteria gets replaced, and we photograph what we find rather than just noting a fail.
What is the service frequency for fire hydrant systems?
Fire hydrant systems are Section 4 of AS 1851-2012, with monthly, six-monthly, yearly and five-yearly routines. Which of those apply to your site depends on how the system is built: a hydrant system fed by a fire pumpset and on-site water storage carries more frequent routines than a simple town main fed system, because there is more that can fail. Pumpsets are separately covered by Section 3 and water storage tanks by Section 5.
System design is to AS 2419. If you are unsure which routines apply to your building, that is exactly what a compliance survey answers.
Are flow tests required on fire hydrants?
Yes. Flow and pressure testing is part of the yearly and five-yearly routines, and it is the only way to prove the system will actually deliver water at the flow and pressure it was designed for. Results are compared against the system's baseline data, so a gradual decline gets caught before it becomes a failure. Booster assemblies are tested as part of this.
What actually happens in a five-yearly hydrant service?
The five-yearly is an inspection and overhaul routine, not an automatic parts replacement. Landing valves are stripped, inspected and overhauled, and re-seated or repacked as required. Isolation and non-return valves are proven. Gauges are verified against a calibrated test gauge. Pipework and the booster assembly are inspected, and hydrostatic and flow testing is carried out.
Components are replaced when they fail the standard's criteria, not on schedule. Be wary of any quote that lists wholesale replacement of landing valves and gauges as a standard five-yearly inclusion, because that is a commercial decision being presented as a compliance requirement.
Can fire hose reels be used on an electrical fire?
No. Hose reels deliver water and water conducts electricity, so using one on live electrical equipment risks electrocution. Use a CO2 extinguisher on live electrical equipment. This is a large part of why extinguisher selection under AS 2444 matters: the right unit needs to be within reach of the risk it is meant to cover.
What is the service schedule for sprinkler systems?
Automatic sprinkler systems are Section 2 of AS 1851-2012 and carry the most demanding schedule of any system. Monthly, six-monthly, yearly and five-yearly routines all apply, and depending on the system type and age there are also longer interval routines at ten, twenty and thirty years covering things like sprinkler head sampling and testing, and internal pipework condition.
Design and installation is to AS 2118. If your building has sprinklers, this is the system where a gap in the record is hardest to explain to an insurer.
Are sprinkler systems mandatory in all buildings?
No, but they are required in a wide range of buildings under the National Construction Code, driven by building classification, height, floor area, occupancy and use. High rise residential and commercial, healthcare, aged care and large retail and warehousing are the usual triggers. Some buildings have them as part of a performance solution, in which case the fire engineer's report sets requirements beyond the standard ones.
What is involved in the yearly sprinkler test?
The yearly covers alarm valve and flow switch operation, water supply proving, valve monitoring, pressure readings against baseline, and a visual survey of pipework, hangers, heads and spare head stock. Where the system has a pumpset, that gets its own performance test against its design duty point under Section 3.
All of it is measured against your baseline data, so results are an objective pass or fail rather than a technician's opinion on the day.
How are sprinkler heads maintained?
Heads are inspected for corrosion, paint, physical damage, loading with dust or product, and for obstruction to the spray pattern, which in warehousing is usually stock stacked too high or new racking or ductwork installed under the heads. Damaged, painted or corroded heads are replaced, never cleaned. Correct spare heads and the head spanner must be kept on site.
On longer interval routines, sample heads are removed and tested to confirm the rest of the population is still sound.
Can a sprinkler system be isolated during maintenance?
Yes, but it has to be managed properly. AS 1851-2012 has impairment requirements: isolation kept as short as practicable, the monitoring service and the building's responsible person notified before and after, the impairment recorded, and additional precautions such as a fire watch where the risk warrants it. The system is restored and proven back in service before we leave.
An isolation that gets forgotten and left in overnight is one of the most serious things that can happen in this trade, which is why it is a documented process and not a verbal arrangement.
How often do fire pumpsets need servicing?
Fire pumpsets are Section 3 of AS 1851-2012, with monthly, six-monthly, yearly and five-yearly routines. Monthly is a run test with starting, pressure and alarm checks. Diesel sets add fuel, battery, cooling and exhaust checks. The yearly is a full performance test against the pumpset's design duty point, proving flow and pressure, auto start, changeover and fault signalling.
A pump that starts is not a pump that performs. The annual flow test against baseline is what tells you whether it will still deliver on the day.
