Check that each worker can isolate your plant correctly, every time: knowledge questions, a practical observation of a real isolation and a clear, recorded outcome.
A verification of competency (VOC) assessment checks that a worker can isolate hazardous energy safely on your plant: identify every energy source, isolate, lock and tag, dissipate stored energy, test for zero energy, and remove the isolation safely. This template gives the assessor a structured way to do it, and a record that shows how the decision was made.
It combines knowledge questions with a marking guide, a practical observation checklist, the evidence the assessor should collect and safety-critical fail criteria (no test for zero energy, for example, is a fail whatever the rest of the score). The assessor and the worker sign off the outcome, and the Excel VOC register tracks who has been assessed and when reassessment is due.
A VOC supports workplace competency verification. It does not replace a high risk work licence where one is required. Electrical isolation work may require a licensed electrician. Follow the manufacturer's instructions and your site's isolation procedure.
Delivered as one ZIP download. The files below are editable, and every Word document also comes as a PDF. Each download also includes Read Me First, a Product Overview, the Permitted Use Terms and Version Information (PDF).

The VOC checks a worker against your isolation procedure. The Hazardous Energy Isolation Pack includes this VOC with the isolation procedure it assesses against, an isolation record and a supervisor field verification checklist of isolation controls.
Tells the operator what to do
The steps, hazards and controls for the task, written for the person doing it.
In the pack
Checks they can do it
Verifies each operator against that same instruction, on your equipment, with evidence and a clear outcome.
Included
Records every isolation
The isolation points, locks and tags applied, the zero-energy test, and who applied and removed them.
In the pack
Checks the controls are working on site
A supervisor checks on the floor that the controls the instruction relies on are in place and effective.
In the pack
What supervisors find in the field feeds back into the instruction and the VOC.

Before you use them
No. Electrical isolation work may require a licensed electrician. Follow the manufacturer's instructions and your site's isolation procedure. The VOC checks that a worker follows your isolation procedure; it does not authorise electrical work.
Someone competent in your isolation procedure and in assessing others, often a maintenance supervisor, a WHS adviser or a workplace trainer and assessor. The template guides the assessment; it does not make the assessor competent.
Set the interval from your own risk assessment. Common triggers are new or modified plant, a change to the isolation procedure, an incident or near miss, an isolation done wrongly in the field, and a worker returning after a long absence.
No licence is needed to apply your site's locks and tags, but workers must be trained and authorised under your isolation procedure. Electrical work, and electrical isolation beyond what your procedure allows, may need a licensed electrician. The procedure sets out who may isolate what, and the VOC checks each worker against it.
Isolation is separating plant from every energy source so it cannot move or release energy while people work on it. Lockout tagout is how that isolation is secured and shown: a personal lock on each isolation point, a tag saying who applied it, and a test for zero energy before work starts. The procedure covers all three, and the isolation record keeps the evidence.
Yes. Every document is supplied in Word (.docx) or Excel (.xlsx), so you can add your logo, change the wording and adapt it to your workplace. The copyright notice must stay.
Yes. The documents must be adapted to your equipment, the manufacturer's instructions, your site and your local controls before they are used. The setup guide in the pack lists what to change.
No document can. Your duties are met by managing the risks in your actual workplace. Using them does not by itself make a workplace compliant with WHS or OHS laws. They support the work of managing the risk; they are not legal advice.
Yes. Every price in the store includes GST, so $69.00 is the total, including $6.27 GST. Your receipt is a tax invoice showing the GST.
As a ZIP download. Card purchases can be downloaded straight away from the confirmation page and by a link we email you. Download links expire after 14 days for security; you can request a new one at any time.
Yes. Use Request an Invoice to order through your normal procurement process, with a purchase order number and quantities if you need them. The files are released once payment is confirmed.
Yes, across your own organisation. The documents are licensed for internal use by the purchasing organisation. A consultant, labour hire business or training provider supplying them to clients needs separate written permission.
They are written for Australian workplaces and refer to Australian WHS and OHS laws and licences. A business elsewhere should replace those references with its own country's requirements. Everything is editable for that.
Your rights under the Australian Consumer Law are not affected. See the Refund Policy for how we handle a document that is faulty, not as described, or not what you ordered.
Licence and legal information here is general. It may not be correct in your jurisdiction: please check with your local WHS or OHS regulator.

Start with a toolbox talk to brief the crew on the hazard, then use the safe work instruction, the VOC and the field verification checklist to set and check the controls.
For workers who clean, clear, maintain or adjust plant: why every energy source must be isolated, locked and proved dead before hands go in.
For workers who use electrical equipment or work near powerlines: how electricity injures, the checks before use, and what to do if someone is shocked.
For workers who use or work near machines: how moving parts injure, how guards work, and why a guard is never removed or bypassed.
Isolation is a common critical control. To manage it as one, with performance standards and field verification across the business, see the Critical Control Management series.
Hazardous energy isolation procedure, isolation record, VOC assessment and a supervisor field verification checklist of isolation controls, written to work together.
