First, describe the work and worksite
An installation crew will fit engineer-specified screened adhesive anchors through the face of an identified hollow-CMU wall at ground level for a later fixture. The accepted wall, permitted locations and actual anchor system govern drilling, installation and cure restrictions. This fictional learning example describes planned controls; it records no actual inspection or work authorization.
- The design and product approval identify the masonry unit, face/cell condition, sleeve, rod and required installation and acceptance criteria.
- The selected drilling and cleaning methods have task-specific dust controls; chemical handling follows the actual adhesive SDS.
- Core drilling, concrete starter bars, assumed solid substrate, facade tie repair and fixture loading before acceptance are excluded.
Questions before work
- What evidence identifies the hollow masonry and permitted anchoring positions?
- Which sleeve, rod and drilling/cleaning method belong to the approved system?
- How will cure conditions, installation findings and the later fixture-loading release be recorded?
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 substrate and anchor locations
Hazard: An anchor in an unsuitable cell, weak face shell or unidentified service can fail or cause contact injury.
Control: Installation lead checks the identified masonry, service investigation and engineer’s anchor schedule against the product’s approved substrate range. Mark permitted locations and drilling limits; hold unknown units, damage or positions outside the released design.
Verification: Lead records substrate identity and location release before drilling.
Why this belongs in the analysis: A hollow wall cannot be treated as a continuous concrete block.
2. Arrange dust and chemical controls
Hazard: Drilling dust, adhesive contact and cluttered access can expose the installer and nearby workers.
Control: Separate the work bay, prepare the system-approved drill and cleaning tools and establish the applicable silica controls. Stage labeled adhesive, sleeves and rods with current SDS, assessed protection, ventilation and washing access; contain dispensing waste.
Verification: Lead checks the dust-control method and identified chemical handling arrangement.
Why this belongs in the analysis: The sleeve installation combines material-specific drilling and chemical exposure.
3. Drill within the released method
Hazard: An unsuitable drill mode can damage the face shell or create an unapproved receiving hole.
Control: Use the actual system’s permitted tool, drill mode and hole criteria with dust controls functioning. Stay within marked limits, control both affected faces where necessary and stop for unexpected void geometry, breakout or a concealed obstruction; do not enlarge the hole to fit another sleeve.
Verification: Installer compares actual hole condition with the required system criteria.
Why this belongs in the analysis: Receiving-hole damage can undermine an otherwise correct adhesive installation.
4. Prepare the hole and sleeve
Hazard: An unclean hole or wrong screen can prevent the anchor system from forming its intended restraint.
Control: Inspect and clean by the system’s approved method and fit the specified compatible screen sleeve. Assess exposure from cleaning and verify sleeve seating and condition; do not omit the sleeve, improvise a tube or copy a solid-concrete hole procedure.
Verification: Installer records hole and sleeve findings before dispensing.
Why this belongs in the analysis: The hollow-substrate system relies on a controlled assembly around the receiving void.
5. Inject and place the rod
Hazard: Unmixed adhesive, poor filling or movement during cure can leave an unsafe fastening.
Control: Check product condition, dispenser and mixing nozzle, then follow the specified discard, dosing and rod-placement method within actual working limits. Protect the rod from movement and keep assessed contact protection in use; do not invent a common cure time.
Verification: Installer records product identity, placement and conditions governing cure.
Why this belongs in the analysis: The product and actual temperature conditions determine the installation window.
6. Isolate loading and hand over
Hazard: A fixture can be attached to an uncured or unaccepted anchor without the receiving crew knowing.
Control: Mark unreleased anchors and prevent attachment or loading until the specified cure and acceptance are complete. Transfer actual installation records, required test findings and open actions to the designated reviewer; dispose of waste under the SDS and site arrangements.
Verification: Receiving lead confirms the loading release or continuing restriction for each anchor.
Why this belongs in the analysis: A visible rod supplies no evidence of cure or tested capacity.
What does a useful control look like?
| Needs improvement | More useful for this scenario |
|---|---|
| Work carefully and wear PPE. | Use the actual system’s permitted tool, drill mode and hole criteria with dust controls functioning. Stay within marked limits, control both affected faces where necessary and stop for unexpected void geometry, breakout or a concealed obstruction; do not enlarge the hole to fit another sleeve. |
| Check that everything is ready. | Installation lead checks the identified masonry, service investigation and engineer’s anchor schedule against the product’s approved substrate range. Mark permitted locations and drilling limits; hold unknown units, damage or positions outside the released design. |
Decisions that change the analysis
Can the installer omit a sleeve because the rod feels firm?
No. Follow the approved system for the identified hollow masonry. Firmness by hand is not an acceptance test, and this example supplies neither an anchor design nor permission to treat a hollow unit as solid concrete.
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
- Masonry identity, face/cell condition or anchor location differs from the approved design.
- Breakout, failed dust control or an incompatible sleeve or cleaning tool.
- Product condition, cure requirements or the fixture-loading release is unresolved.
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
- The actual hollow-masonry anchor system’s approved substrate, drill mode, cleaning, sleeve, dispensing and cure procedure.
- Applicable silica and hazard-communication instruction, contact protection and installation-record/acceptance responsibilities.
Confirm applicable qualifications, task instruction and actual training evidence for the people assigned. Related toolbox talks support toolbox talks; 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.
