Stop work
Stop for ground movement, changing wind beyond the approved limits, unapproved panel handling, overload, loss of communication, a failed safety function or entry into the exclusion zone. Do not force a panel into place using the boom or release a loose panel to recover stability.
1. Legal and technical scope
| Basis | Application limits |
|---|---|
| Safe Work Australia — EWP risk management | National guidance on selection, site hazards, wind, protection and planning; check local legislation. |
| WorkSafe Queensland — EWP inspector guide | Technical guidance on material loads and side forces. Older document: references and model applicability require checking. |
Australia: state or territory legislation governs the site. Safe Work Australia provides guidance rather than acting as the site regulator. Determine the applicable high risk construction work and SWMS duties and the operator licensing requirements for the actual boom.
For an EWP boom of 11 m or more, verify the applicable WP high risk work licence requirement with the local regulator; training and familiarisation remain necessary for other EWPs. The Queensland inspector guide is a jurisdiction-specific technical reference with older standard references, not a current national law or a panel-carrying approval.
2. Scope and required inputs
Included scope
Installing external cladding panels from a truck-mounted boom platform, with an independently planned panel lift or a specifically approved material-handling configuration. Includes setup, workface positioning, fixing, lowering and road departure.
Separate review
Using the basket or boom as an improvised crane, carrying an unapproved external panel, climbing out at height, live-line work and improvised rescue are outside this procedure. Choose separate lifting equipment when panel carriage is not permitted.
| Required input | What to verify |
|---|---|
| Machine and panel | Model, inspection history, approved attachment or independent lift, panel mass/area, occupants, tools and permitted load distribution. |
| Setup | Ground capacity, buried services, voids, slab limits, maximum outrigger reactions, suitable pads and traffic/exclusion arrangements. |
| Workface | Fixing design and sequence, reach, trapping points, electrical isolation/clearances, wind at the work height and communication. |
| Rescue and handover | Trained ground responder, available lower controls, emergency lowering within the manufacturer procedure, secure panel state and receiving supervisor. |
Use the actual machine and attachment instructions for ground reactions, pad design, extension, capacity, side forces, panel dimensions and wind. No universal three-times-pad-area rule, 32 km/h panel limit, 12.5 m/s permission or electrical clearance is set here. Verify local electrical and road requirements separately.

4. Fictional scenario and failure mechanisms
The original educational image is retained. It is not evidence of an actual incident or site suitability.
The scenario and record comparisons are fictional teaching examples, not records of real incidents, measurements, inspections, signatures or approvals.
| Item | Fictional scenario |
|---|---|
| Initial situation | Fictional example: installers approach a facade with a panel supported by a separately planned lifting system. |
| Changed condition | Wind increases while the crew is still aligning the panel and only some fixings are installed. |
| Failure path | Panel movement can load workers and basket sideways; premature lifting-release could leave the panel unsupported. |
| Possible outcome | The result could be trapping, falling material, loss of balance or machine instability. |
| Prevention barrier | Stop the alignment, keep the panel controlled by its planned supports and use the defined safe lowering or securing method. Do not drop it. |
Failure mechanisms
Outrigger reactions vary with configuration, reach and loading. Average truck weight divided by four is not a reliable pad design load. Check ground and pad capacity together, including voids, excavations, buried services and rainfall changes. A larger pad alone does not repair weak ground or a failing slab.
A broad panel adds wind area and may apply side load beyond the machine design. Remaining below the basket mass rating does not prove that an external load, rack or suction device is allowed. Consider panel lifting and installer access as separate systems unless the exact combined use is approved.
Fasteners transfer panel load to the building only after the required arrangement is installed and checked. The basket must not temporarily carry building loads or push the panel into alignment. Keep hands out of closing gaps, feet on the platform floor and the rescue route available.
Decision sequence
| Decision stage | What to verify |
|---|---|
| Known facts | The panel is aligned but the required fixings are not all verified. |
| Unresolved matters | Fixing engagement, temporary restraint and the wind condition remain unresolved. |
| Reason to hold | Releasing the lifting support would transfer load to an unconfirmed connection. |
| Required evidence | Check the fixing schedule, installed connections, temporary restraint and safe wind/handling conditions. |
| Restart decision | The designated person confirms secure support and authorises release according to the panel erection method. |
5. Conditional decisions and common errors
| Condition | Action | Evidence | Proceed when |
|---|---|---|---|
| Handling unapproved | Hold the lift; select an approved arrangement | Machine, attachment and panel documentation | Method approved |
| Ground uncertain | Keep boom stowed; assess support | Reactions, ground, pads and buried services | Support verified |
| Wind or movement | Stop alignment; secure or lower as planned | Work-height wind and panel restraint | Conditions restored |
| Fixings incomplete | Maintain planned panel support | Fixing sequence and installed connections | Fixings verified |
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 |
|---|---|---|
| Capacity | Total mass is below rating: still check side load and panel area | Approved complete handling configuration: assess site conditions |
| Support | Outriggers look level: ground capacity remains unproven | Ground, reactions and pads verified for the actual configuration |
| Release | Panel appears aligned: keep lifting support | Required fixings and restraint checked: release may be authorised |

Stop work
Stop for ground movement, changing wind beyond the approved limits, unapproved panel handling, overload, loss of communication, a failed safety function or entry into the exclusion zone. Do not force a panel into place using the boom or release a loose panel to recover stability.
Emergency response
Use the rehearsed ground-control or rescue procedure appropriate to the fault and hazards. Keep people away from an unstable machine, live electrical contact or suspended panel. Call emergency services and the electricity operator where relevant; do not climb the boom or improvise a transfer.

Can the panel be hung from a basket rail?
Only use a material-handling arrangement expressly permitted for the machine and configuration. Otherwise use a separate suitable lifting system; rails are not improvised lifting points.
Does a normal wind rating cover a large panel?
No automatic conclusion follows. The machine, attachment and panel handling limits must all be met, including gusts and local effects at the work height.
Is a spotter permission to approach a live line?
No. Establish the applicable clearance or an authorised electrical safety arrangement with the responsible electricity operator. Account for every part of the machine, panel, tools and people.
Can workers drop the panel if the machine moves?
Do not adopt dropping as a recovery method. Plan controlled securing/lowering and rescue before work; stop and keep the danger area clear if stability is in doubt.
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.

Valid controls for ground, pads, pre-use checks, capacity, electrical separation, wind, feet on the floor, falling objects and road movement were retained. The fictional example no longer claims a regulator investigation or measured casualties. Generic wind values and a claim that the platform calculates compliant pad sizes were removed. Separate panel lifting, fixing-release and rescue checks were added.
