Fire pumpset installation and commissioning is high risk construction work in New South Wales because commissioning cannot be done dead. Installation largely can — but proving a controller, verifying automatic start and testing under flow all require the equipment energised: a 415 V controller, an auto-start diesel and a pressurised system, simultaneously. Section 291 of the Work Health and Safety Regulation 2025 (NSW) captures the work under the energised electrical category, and a safe work method statement is required under section 299. SafeWork NSW is the regulator. AS 2941 governs the pumpset itself and its commissioning regime.
A fire pump is designed to start by itself, with nobody there, the instant pressure drops. That is its entire purpose, and it is why commissioning this equipment is not comparable to commissioning an ordinary pump. During commissioning the crew deliberately creates the exact condition the pumpset is built to respond to — a pressure drop — while working on and around it. A worker with a hand on a coupling, a guard off, or a spanner on a flange when the pressure switch trips does not get a warning. The pump does not know the difference between a fire and a commissioning test.
So the controls that matter here are isolation controls that account for automatic and remote initiation. Killing the run command is not isolation. This SWMS requires the pressure switch, the remote and BMS signal and the diesel start circuit all isolated and locked, the start batteries physically disconnected for mechanical work, and rotation verified as physically impossible — not inferred from a lamp or a screen. It also requires that any defeat of the automatic start is documented and reversed before the crew leaves, because a defeated fire pump is a building with no fire protection.
Hazards identified
14 hazards covered, sorted by priority.
Fatality — the pump starts on a pressure drop with a worker in contact with the coupling
Fatality — electrocution from the 415 V controller during termination or commissioning
Fatality or catastrophic burns — arc flash causes burn and blast injury together
Fatality — entanglement in the rotating coupling or shaft during a running test
Fatality — a joint, blank or gauge released as a projectile at test pressure
Fatality — carbon monoxide asphyxiation in an enclosed, often below-grade pump room
Fatality — crush injury from the pumpset during placement in a restricted pump room
Permanent noise-induced hearing loss — a diesel fire pump at full flow in a concrete room
Fatality — asphyxiation or engulfment in a pump room, suction well or tank
Serious injury — pipework movement, or a worker at a flange during a surge
Fire or explosion from diesel vapour ignited in an enclosed pump room
Acid burns, and arc injury from a short across battery terminals
Serious burns from the exhaust, manifold or engine block after a run
Musculoskeletal injury from handling valves, batteries and pipe in restricted space
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Isolate and lock out the controller, the supply AND the automatic start path — the pressure switch at the sensing line, the remote and BMS signal, and the diesel start circuit — before any person touches the pumpset. Killing the run command is not isolation.
- 2Physically disconnect the diesel start batteries for any mechanical work, and verify rotation is impossible physically rather than from a lamp, a panel or a control-room screen.
- 3Place the controller in manual and defeat the automatic start only under a documented regime that is recorded and reversed before the crew leaves — a defeated fire pump is a building with no fire protection.
- 4Complete all installation, termination and pre-energisation verification dead. Energised electrical work is prohibited under Part 4.7 Div 4 ss.154 & 157 unless de-energisation is not reasonably practicable, and installation is never such a case.
- 5Identify in advance the commissioning tasks that genuinely require energisation, carry them out under a documented safe work method with a competent person and a second person present who can isolate and perform rescue.
- 6Obtain an arc flash risk assessment establishing incident energy and approach boundaries, verify upstream protection, and close the panel door for any test that can be done closed.
- 7Fit and secure coupling and shaft guards and never remove them for a running test, with an emergency stop reachable from the working position.
- 8Prohibit loose clothing, cuffed sleeves, lanyards and unrestrained hair near the running pumpset, and exclude persons from the coupling area during any run.
- 9Verify the exhaust system is complete, sealed and discharging outside the building before the first run, with continuous CO monitoring in the room during every run.
- 10Pressurise for hydrostatic test with the area cleared and nobody in line with a flange, blank, gauge or cap, with relief set below the weakest component and air vented from the system.
- 11Plan the placement route, lifting points and final position before delivery, and keep no person between the load and a fixed structure in a pump room where there is nowhere to retreat.
- 12Run the pumpset with the room clear and monitor test parameters from outside where the arrangement allows, and provide double hearing protection where the room must be occupied.
- 13Treat the pump room, suction well or tank as a confined space where entered — permit, atmospheric testing, standby person who does not enter, and rescue in place before entry.
- 14Open and close valves slowly, vent air before pressurisation, and keep no worker at a flange, joint or gauge during start, stop or valve operation.
Applicable Codes of Practice
The benchmark for isolation, testing for dead, arc flash risk and the conduct of energised work where it cannot be avoided — the category that makes this work high risk construction work.
The benchmark for guarding of rotating couplings and shafts, isolation and lock-out including automatic and remote initiation, and safe use of the pumpset.
The benchmark for entry permits, atmospheric testing, ventilation, standby and non-entry rescue where a pump room, suction well or tank is entered.
The design, installation, testing and commissioning of fire pumpsets, including the controller, the automatic start arrangement and the commissioning test regime.
The system the pumpset serves, its hydrostatic test requirements and its commissioning verification.
The installation, termination and verification requirements for the controller and its supply, including testing before energisation.
High-Risk Construction Work triggered
A fire pump room is frequently below grade, and suction wells and tanks are entered for connection, inspection and testing. Diesel exhaust, fuel vapour and restricted egress make the space a confined space under Part 4.3 Division 2.
Commissioning necessarily energises. Proving the controller, verifying automatic start and testing under flow cannot be done dead — this is the category that makes the work high risk construction work rather than a specialist install.
A diesel pumpset run in an enclosed, often below-grade pump room fills the space with carbon monoxide if the exhaust is incomplete, and the fuel system introduces vapour into the same space.
A crane or gantry places the pumpset into the pump room, and the room's restricted access means the load travels close to fixed structure with limited room to retreat.
Carrying out high risk construction work without a compliant SWMS is an offence under the Work Health and Safety Regulation 2025 (NSW). An unexpected pump start causing injury during commissioning attracts immediate SafeWork NSW attention, and the SWMS is the first document requested. Where it records only isolation of the run command and not of the automatic start path, it is evidence that the PCBU did not understand the equipment it was commissioning.

Worked example
A technician is commissioning a diesel fire pumpset in a basement pump room. The controller has been proved and the pump has run. The last task is a leak on a flange at the discharge. The technician presses stop at the controller, watches the pump wind down, waits for the panel to show stopped, and puts a spanner on the flange. Stopping the pump released the discharge pressure. The pressure switch senses the drop and calls for start. The controller is in automatic because nobody put it in manual — the run command was cancelled, but the automatic start path was never touched. The pump starts against a technician leaning over the coupling. The controls in this SWMS break that chain in three places. Isolation is defined to include the automatic start path — the pressure switch at the sensing line, the remote and BMS signal, and the diesel start circuit — and not merely the run command. The start batteries are physically disconnected for mechanical work, so there is no energy to crank with regardless of what the controller decides. And rotation is verified as physically impossible before contact, rather than inferred from a panel indication that reports what the controller was last told rather than what it is about to do. The SWMS also requires the defeat to be recorded and reversed before the crew leaves, and the building notified, because for the duration the building has no fire protection.

Frequently asked questions
Why is this $199 rather than a $149 specialist SWMS?
Because commissioning cannot be done dead. Installation largely can, and if the product covered installation alone the classification would be arguable. But proving the controller, verifying automatic start and testing under flow all require the equipment energised — that engages the energised electrical category at section 291 squarely. The commissioning scope is what makes this high risk construction work, and it is named in the document rather than assumed.
We stopped the pump at the controller. Isn't that isolation?
No, and this is the failure mode the SWMS is built around. Stopping the pump cancels the run command. It does not touch the automatic start path — the pressure switch, the remote or BMS signal, or the diesel start circuit. A fire pump is designed to start on a pressure drop with nobody there, and stopping it creates exactly that pressure drop. Isolation means locking out the start path and physically disconnecting the start batteries, then verifying rotation is impossible.
Does the SWMS deal with the building being unprotected during commissioning?
Yes. Any defeat of the automatic start must be documented and reversed before the crew leaves, and the building notified for the duration. A defeated fire pump is a building with no fire protection, and a defeat left in place at knock-off is a serious exposure for both the contractor and the building owner. It is treated as a control, not a courtesy.
Is the pump room a confined space?
Frequently, yes. Fire pump rooms are often below grade, and suction wells and tanks are entered for connection and testing. Diesel exhaust accumulates where it cannot disperse, fuel vapour is introduced by the fuel system, and egress is restricted. Where entry is in scope the SWMS requires a permit, atmospheric testing, a standby person who does not enter, and rescue arrangements in place before entry.
