First, describe the work and worksite
A specialist stone crew will install identified exterior granite cladding panels on a released ground-floor facade using specified mechanical anchors and a rated panel-handling device. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- Panel condition, anchor substrate, bearing and temporary support come from the engineered cladding details.
- Drilling occurs only at released anchor locations with the applicable dust controls.
- Adhered veneer, on-site stone fabrication, upper-story facade work and substituting adhesives for anchors are excluded.
Questions before work
- Which anchors and substrate checks establish this panel’s load path?
- What lifting device is approved for the stone surface and panel weight?
- Which temporary supports remain until the connection checks are complete?
Build the analysis one step at a time
What will the worker do? How could someone be harmed? What prevents or reduces that exposure? Who checks the control, and when?
1. Release the cladding detail
Hazard: An incompatible anchor or weak substrate can allow a panel to fall.
Control: Stone lead verifies current engineered panel, bearing and anchor details and the substrate release. Refer uncertain edge distances, substrate damage or panel changes before drilling.
Verification: Lead compares panel schedule and anchor locations with released documents.
Why this belongs in the analysis: A finish-panel location does not establish its support capacity.
2. Inspect and stage stone
Hazard: Cracked panels or unstable storage can fail during pickup.
Control: Check panel identity, condition and specified handling points; segregate damaged stone for technical review. Stage on suitable restrained supports and maintain a clear transfer route.
Verification: Handling lead inspects condition and support before attachment.
Why this belongs in the analysis: Natural stone condition affects both handling and anchorage.
3. Prepare anchor points
Hazard: Drilling can strike services or expose workers to dust.
Control: Investigate and release the drilling locations and depths. Use the specified anchor installation process and applicable dust controls; obtain required substrate/anchor checks without inventing acceptance values.
Verification: Assigned installer records actual hole and anchor checks against the approved system.
Why this belongs in the analysis: Anchor preparation is part of the permanent load path.
4. Lift and position the panel
Hazard: Stone can drop, rotate or trap workers against the facade.
Control: Use the rated stone-compatible handling system with inspected attachments and agreed signals. Keep people outside the drop and pinch paths; place the panel on its specified temporary bearing/support.
Verification: Handling lead verifies support before the crew approaches connection work.
Why this belongs in the analysis: A glass handling device is not automatically suitable for stone.
5. Complete mechanical restraint
Hazard: An incompletely connected panel can move when lifting support is released.
Control: Install the specified anchors, bearings and required tolerances without forcing the stone. Retain handling/temporary support until designated connection checks and release are complete.
Verification: Stone lead verifies each required support and restraint before disconnecting the device.
Why this belongs in the analysis: Apparent alignment does not prove the panel is safely restrained.
6. Hand over the facade
Hazard: Unfinished anchors or removed temporary supports can expose other trades.
Control: Identify incomplete panels, remaining supports and loading/access restrictions. Clear the work zone and transfer inspection findings and open actions to the facade lead.
Verification: Receiving lead confirms each panel’s release status.
Why this belongs in the analysis: The handover must follow individual connection status, not visual finish.
What does a useful control look like?
| Needs improvement | More useful for this scenario |
|---|---|
| Work carefully and wear PPE. | Investigate and release the drilling locations and depths. Use the specified anchor installation process and applicable dust controls; obtain required substrate/anchor checks without inventing acceptance values. |
| Check that everything is ready. | Stone lead verifies current engineered panel, bearing and anchor details and the substrate release. Refer uncertain edge distances, substrate damage or panel changes before drilling. |
Decisions that change the analysis
Can the adhered veneer mortar method replace an anchor?
No. Mechanically anchored dimension stone has an engineered load path. Any change in panel, anchor, bearing or attachment needs the responsible designer’s review; adhesive veneer instructions are not a substitute.
What must the crew record for actual use?
Identify the actual equipment and work boundaries, responsible people, applicable criteria, inspection findings and open actions. Resolve changes with affected crews and obtain required project authorization before work.
Agree when the crew will pause
- Stone damage, unknown weight or incompatible handling device.
- Anchor substrate, drilling release or support differs from the design.
- Connection checks are unresolved or a temporary support change is proposed.
After a pause, correct the condition, reassess the work, and obtain required authorization before restarting. Keep unresolved actions visible.

1. Describe your work and site
2. Work through each task
Describe an observable step, how someone could be harmed, and the control that acts on that hazard. Identify who checks it and what evidence is needed.
3. Record changes, checks, and open actions
Walk the work area, review with the crew, and resolve missing controls. Follow the required approval process. This tool does not judge completeness, verify signatures or authorize work.

Training needs to confirm
- Stone-specific handling-device and anchorage installation instruction.
- Applicable rigging/handling qualifications and silica controls for actual anchor drilling.
Confirm applicable qualifications, task instruction and actual training evidence for the people assigned. Related toolbox talks support crew discussion; they do not establish competence.
Common questions
Can this example be used as a JSA?
Adapt its Task | Hazard | Control analysis to the employer’s format and actual conditions. The example is a teaching aid, not evidence that controls were checked.
What changes if the project requires an AHA?
Use the governing AHA format, risk method, supporting records and acceptance process. The published formwork AHA demonstrates that additional structure; changing a JHA title does not supply it.
Are these resources part of a paid course?
