Stop work
Stop for unknown feeds, failed dead testing, damaged ladder, insecure footing, people entering the zone, overreach or unsupported fitting. A wall switch or a non-contact detector alone does not establish safe isolation.
1. Legal and technical scope
| Basis | Application limits |
|---|---|
| Safe Work Australia · Electrical safety | Public guidance on electrical risk management; no site isolation test performed. |
| HSE · Ladder types and safe use | Access, standing position and contact guidance; not Australian law. |
Australia: Safe Work Australia electrical guidance is a model reference; confirm state or territory rules, electrical licensing and the actual access equipment. HSE ladder advice is foreign technical guidance.
2. Scope and required inputs
Included scope
Covers access selection, ladder inspection, electrical isolation, removal, replacement, testing and handover of a light fitting. Select a safer platform when duration, reach, weight or two-handed force makes ladder work unsuitable.
Separate review
Live electrical work, specialist access systems and structural alteration need separate competent arrangements. This sheet does not authorise electrical work or prove a circuit is dead.
| Required input | What to verify |
|---|---|
| Select access method | Task and duration · Access equipment selection · Circuit identification · Fitting weight and support |
| Inspect and position | Ladder identification · Feet steps and stays · Floor and door controls · Work-zone barriers |
| Isolate and prove dead | Isolation record · Test instrument checks · Point-of-work test · Restart authority |
| Ascend and transfer | Climbing contact · Tool retention · Load transfer method · Exclusion maintained |
| Remove old fitting | Fitting support · Waste container · Isolation still effective · Reach and posture |
| Clear and hand over | Waste record · Ladder post-use condition · Storage restraint · Test and handover record |
Use the exact ladder's instructions for load, opening, restraint and permitted standing level. Do not impose a universal top-two-step rule on every platform design. State or territory electrical licensing and applicable safety requirements must be checked; paid standards and actual manuals were not read.
Use sound footwear, tool retention and suitable eye and hand protection. A fibreglass ladder is not electrical isolation. A helper does not make overturning impossible or justify an unsuitable access method.

4. Fictional scenario and failure mechanisms
Retained educational illustration; not evidence of an actual incident.
The scenario and record comparisons are fictional teaching examples, not records of real incidents, measurements, inspections, signatures or approvals.
| Item | Fictional scenario |
|---|---|
| Initial situation | A fictional worker prepares to replace a ceiling light from a stepladder. |
| Changed condition | The wall switch is off, but another supply has not been identified and the fitting needs two hands to support it. |
| Failure path | Unexpected voltage can cause shock, while reaching and supporting the weight can overturn the ladder. |
| Possible outcome | A helper holding the feet cannot remove these electrical and access failures. |
| Prevention barrier | Hold work, select suitable access and handling, isolate relevant feeds and verify dead at the work point before release. |
Failure mechanisms
Safe isolation requires identifying all relevant sources, preventing reconnection and verifying dead with a suitable instrument whose function is checked before and after testing. Stored energy also needs control.
Climbing contact and a safe working posture are different questions. If the task needs sustained two-handed force or overreach, change the access arrangement.
Total load includes the person, fitting and tools. Stand only on manufacturer-permitted steps or platforms; the top cap is not a work platform unless designed as one.
Decision sequence
| Decision stage | What to verify |
|---|---|
| Known facts | A fictional worker prepares to replace a ceiling light from a stepladder. |
| Unresolved matters | The wall switch is off, but another supply has not been identified and the fitting needs two hands to support it. |
| Reason to hold | Unexpected voltage can cause shock, while reaching and supporting the weight can overturn the ladder. |
| Required evidence | Isolation record · Test instrument checks · Point-of-work test · Restart authority |
| Restart decision | Hold work, select suitable access and handling, isolate relevant feeds and verify dead at the work point before release. |
5. Conditional decisions and common errors
| Condition | Action | Evidence | Proceed when |
|---|---|---|---|
| Circuit uncertain | Hold and identify all feeds | Circuit and isolation records | Isolation verified |
| Both hands under load | Change access and handling | Task assessment and support plan | Stable work position available |
| Ladder defect | Remove from service | Inspection and replacement record | Suitable ladder confirmed |
| Re-energisation | Test and clear people | Test results and restoration authority | Controlled restoration authorised |
Similar situations, different decisions
The scenario and record comparisons are fictional teaching examples, not records of real incidents, measurements, inspections, signatures or approvals.
| Comparison | Situation A | Situation B |
|---|---|---|
| Isolation | Wall switch off | Prove dead at the work point after full isolation. |
| Helper | Feet held firmly | Select equipment suitable for the whole task. |
| Standing level | Same rule for all ladders | Follow the actual design and instructions. |

Stop work
Stop for unknown feeds, failed dead testing, damaged ladder, insecure footing, people entering the zone, overreach or unsupported fitting. A wall switch or a non-contact detector alone does not establish safe isolation.
Emergency response
Secure the area and call the site emergency response. Do not touch an electrically exposed person before the supply is safely controlled. Any rescue at height needs a planned safe method. Reassess after the event before restarting.

Does fibreglass make electrical work safe?
No. It does not replace isolation, verification or qualified work.
Is a non-contact detector enough?
No. Use the approved dead-testing procedure and suitable verified instrument.
Must a helper always hold the ladder?
Controls depend on the risk assessment and instructions; a helper cannot correct unsuitable access.
Can the fitting be energised immediately?
Only after required inspection and testing, accounting for people and tools, and controlled authorisation.
Has a professional verified or approved this document?
No. Public sources and editorial, layout and consistency checks were reviewed using AI. No site inspection or professional technical approval has been performed. Obtain appropriate professional review before use.
