Energised Live Electrical Work SWMS
Testing, fault-finding, thermography and switching on energised low-voltage and high-voltage electrical installations where de-energisation is not reasonably practicable. Includes risk assessment, approach distance, PPE category selection, observer/safety-watcher arrangements and emergency response.

Energised electrical work — including live testing, fault-finding, infrared thermography and switching operations on low-voltage and high-voltage installations — exposes workers to arc flash, electric shock, arc blast and induced voltage hazards that can cause fatal injury within milliseconds. Under WHS Regulation 2025 Part 4.4, work on or near energised electrical installations is classified as High Risk Construction Work (HRCW Category 9) and a Safe Work Method Statement must be prepared, consulted on with affected workers, and available at the workplace before work commences. AS/NZS 4836:2023 and the Electrical Safety Code of Practice require that live work only proceed where de-energisation is not reasonably practicable, with a documented justification, approved approach distances, arc-rated PPE selected to the calculated incident energy, and a competent safety observer present. This SWMS provides the structured risk assessment, control hierarchy and verification record that the PCBU, licensed electrical worker and regulator require to demonstrate compliance and discharge the primary duty of care under section 19 of the WHS Act.
Hazards identified
7 hazards covered, sorted by priority.
Third-degree burns to face, airways and torso, retinal damage, hospitalisation and potential fatality from thermal blast
Ventricular fibrillation, cardiac arrest, deep tissue burns at entry and exit points, possible fatality
Blunt trauma, hearing loss, lung barotrauma, shrapnel penetration injuries and secondary fall from elevated platforms
Unexpected shock during assumed-safe contact, muscular contraction causing falls or secondary injury
Meter explosion, operator hand and facial burns, fragment injuries and loss of supply continuity
Flashover to nearest earthed object, equipment destruction, regulatory breach and worker electrocution
Extended arc duration multiplies incident energy beyond PPE rating, causing burns through arc-rated clothing
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — De-energise, isolate, lock out and verify dead using a tested-proven-tested two-point voltage detector before any planned work; live work only by documented exception.
- 2Elimination — Defer non-urgent thermography and diagnostics to scheduled outage windows where production or safety systems permit isolation without greater risk.
- 3Substitution — Replace contact-based testing with non-contact infrared windows, permanently-installed voltage indicators and remote racking devices to remove worker from arc flash boundary.
- 4Substitution — Use Category III/IV-rated digital multimeters with fused leads in place of legacy analogue instruments lacking energy-limiting protection.
- 5Engineering — Install arc-resistant switchgear, current-limiting fuses and zone-selective interlocking to reduce calculated incident energy below 8 cal/cm² where reasonably practicable.
- 6Engineering — Erect insulated barriers, rubber matting rated to system voltage and physical exclusion zones around the arc flash boundary calculated per IEEE 1584.
- 7Administrative — Issue an Electrical Access Permit, conduct pre-start risk assessment, brief this SWMS, and post a competent safety observer trained in CPR and rescue.
- 8Administrative — Restrict live work to licensed electrical workers holding current low-voltage rescue and resuscitation certification, with two-person rule enforced at all times.
- 9PPE — Wear arc-rated coveralls, balaclava and face shield matched to calculated incident energy (minimum PPE Category 2, 8 cal/cm²), Class 0 insulating gloves with leather protectors.
- 10PPE — Use voltage-rated safety footwear, hearing protection, ANSI Z87.1 safety glasses under the arc hood, and remove all conductive jewellery and metal-framed eyewear before approach.
Applicable Codes of Practice
Defines competency, approach distances, justification process and observer requirements for any work where de-energisation is not reasonably practicable.
Sets installation safety requirements, protection coordination and verification testing that govern fault-current assumptions used in arc flash calculation.
Specifies PCBU duties under WHS Regulations 140–165 including risk assessment, control of inadvertent re-energisation and emergency response planning.
Provides the calculation basis for incident energy, arc flash boundary and PPE category selection referenced in the live work risk assessment.
High-Risk Construction Work triggered
Testing, switching and thermography are performed with conductors energised at low or high voltage within the arc flash boundary, directly meeting the Schedule 1 criterion.
The PCBU must prepare, consult on and retain this SWMS for the duration of work plus two years after any notifiable incident; failure attracts Category 1–3 offences with penalties that are substantial and indexed, with the current maximum following the prevailing WHS schedule.

Worked example
On a Tier 2 hospital upgrade, the electrical foreman is tasked with thermographic inspection of the main switchboard feeding life-support circuits — isolation is rejected because shutdown would compromise patient safety, satisfying the 'not reasonably practicable' test. At the 6:45am pre-start, the foreman opens this SWMS on the site tablet and walks the two-person crew through each line: the team confirms the upstream protection settings, retrieves the IEEE 1584 incident energy study showing 6.3 cal/cm² at the working distance, and selects PPE Category 2 arc-rated kit accordingly. The hazard register prompts the licensed worker to verify his CAT IV multimeter calibration sticker and the safety observer's current LV rescue ticket. Both workers sign the SWMS sign-on register and the Electrical Access Permit. Mid-task, the observer notices the worker's planned approach would bring a metal torch within the restricted zone — referring to the control measures section, they pause, swap to a non-conductive inspection mirror and document the deviation in the live amendment field. After completion, the SWMS is countersigned, the permit closed out, and the document filed against the project HRCW register for the statutory retention period, providing the principal contractor with auditable evidence of consultation and control.
