Electrical final fit-off is the second-fix stage where licensed electricians terminate, test and energise fixed wiring accessories β GPOs, switches, light fittings, exhaust fans, smoke alarms, oven and cooktop points, and switchboard circuit breakers β after rough-in cabling is complete. This work routinely involves proving dead, terminating live-capable conductors, conducting insulation resistance and polarity verification, and energising circuits for the first time, all of which carry electrocution, arc flash and fire ignition risks. Under WHS Regulation 2025 Part 4.4, work on or near energised electrical installations is classified High Risk Construction Work (HRCW), making a Safe Work Method Statement legally mandatory before any worker commences the task. The SWMS must identify hazards, document the hierarchy of controls applied, be developed in consultation with workers under s47, and be available at the workplace for the duration of the work under reg 300. PCBUs (including sole-trader electrical contractors) carry the primary duty under s19 of the WHS Act and must ensure the SWMS is followed, reviewed after any incident, and retained for at least two years.
Hazards identified
7 hazards covered, sorted by priority.
Electrocution, ventricular fibrillation, deep tissue burns, cardiac arrest and fatality; prosecutable Category 1 offence under WHS Act s31
Third-degree burns to face and hands, retinal damage, blast lung injury and permanent hearing loss from pressure wave
Subsequent user electrocution, equipment damage, statutory breach of AS/NZS 3000 cl 8.3 and licensing disciplinary action
Falls from 1.8β3 m causing fractures, spinal injury, traumatic brain injury and permanent incapacity for affected worker
Acute respiratory irritation, dermatitis, and long-term risk of fibrotic lung disease from repeated SMF and silica exposure
Insulation breakdown, fire ignition in wall cavities, property loss and potential occupant fatality if undetected before handover
Lumbar strain, rotator cuff injury, crush injury to fingers and lost-time injury claims under workers compensation
Control measures
Hierarchy-of-controls order: elimination β substitution β isolation β engineering β administrative β PPE.
- 1Elimination β Where practicable, complete all terminations and insulation resistance testing on de-energised circuits with the main switch locked open at the meter panel before any conductor handling.
- 2Elimination β Schedule final fit-off before tenant occupation or other trades return, removing third-party exposure to test leads, exposed terminals and temporary energisation hazards.
- 3Substitution β Use pre-terminated luminaire flex-and-plug systems and modular Wago-style lever connectors in lieu of screw terminals where AS/NZS 3000 cl 3.7 permits, reducing live-terminal exposure time.
- 4Engineering β Apply lock-out tag-out at the switchboard using a personal padlock and danger tag compliant with AS/NZS 4836; verify isolation with a two-pole tester proven on a known live source immediately before and after.
- 5Engineering β Install upstream RCD protection (Type A, 30 mA) on the test supply and use a portable RCD-protected lead for any temporary energisation during commissioning per AS/NZS 3012.
- 6Administrative β Conduct a documented pre-start briefing reviewing this SWMS, isolation point, test sequence and emergency response; record sign-on of every worker before tools are picked up.
- 7Administrative β Restrict energisation and live testing to the licensed electrician in charge; apprentices and second persons remain outside the arc boundary until the circuit is proven safe.
- 8Administrative β Complete AS/NZS 3000 cl 8.3 mandatory tests (continuity, insulation resistance β₯1 MΞ©, polarity, correct connection, earth fault loop impedance, RCD operation) and issue a Certificate of Electrical Safety before handover.
- 9PPE β Wear Category 2 arc-rated coveralls, arc-rated face shield, Class 0 (1000 V) insulating gloves with leather overgloves, and AS/NZS 2210.3 safety footwear with electrical hazard rating during all live work.
- 10PPE β Use P2 respiratory protection and safety glasses when working in ceiling spaces with SMF insulation, plus cut-resistant gloves when handling cable, fixtures and switchboard chassis edges.
Applicable Codes of Practice
Mandates Section 8 verification testing β insulation resistance, polarity, earth continuity and RCD operation β before any final subcircuit is energised or placed in service.
Sets the isolation, proving-dead and access procedures required under WHS Reg 2025 reg 14 for any work where live exposure is foreseeable.
Provides the regulator-endorsed methodology for risk assessment, isolation, and competent person requirements supporting WHS Reg 2025 regs 147β165.
Governs ladder selection, three-points-of-contact rule and fall-prevention duty for luminaire and smoke alarm installation above 2 m under reg 78.
High-Risk Construction Work triggered
Final fit-off involves terminating final subcircuits, energising switchboards and live polarity/loop impedance testing β all foreseeably bringing workers within the AS/NZS 4836 arc-flash and shock boundary.
PCBUs must prepare, consult workers on, and implement this SWMS before work starts under reg 299β300; breach attracts substantial and indexed penalties β current maximum follows the prevailing WHS schedule β and the SWMS must be retained for two years after any notifiable incident.

Worked example
On a mid-rise apartment fit-out, the site electrician arrives Monday for final fit-off of Unit 14 β GPOs, downlights, exhaust fan, smoke alarm and the apartment distribution board. At the 6:45 am pre-start, the supervisor opens this SWMS on a tablet at the tailgate, walks the two-person crew through the seven listed hazards and confirms today's isolation point is the apartment's main switch at the riser cupboard. The apprentice asks about the ceiling-space dust β the supervisor points to control item 10 and issues P2 respirators and safety glasses from the van. Both workers sign the SWMS register, including the apprentice acknowledging they will remain outside the arc boundary during energisation. Mid-morning, the electrician locks out the riser, proves dead with a two-pole tester on a known live GPO downstream, then completes terminations. Before energising, they run the AS/NZS 3000 cl 8.3 test sequence β insulation resistance reads 0.7 MΞ© on the lighting circuit, below the 1 MΞ© threshold. Following the SWMS, work stops; the electrician traces the fault to a pinched neutral behind a downlight, repairs it, retests at 180 MΞ©, then energises with arc-rated PPE on. The supervisor notes the deviation and retest on the SWMS review log, and at smoko re-briefs the crew on cable-protection during luminaire seating β a live, document-driven adjustment captured for the next unit.
