What an isolation permit form is
An isolation permit form is a permit-style document that records how a source of energy or service has been isolated and made safe before work, who authorised it, and the steps for safely returning it to service. It is used to prevent unexpected start-up or release of stored energy.
This page is an educational overview with a simplified example. It is not an official template and not jurisdiction-specific — the employer decides what their isolation process and permits must cover.
Purpose
- Record that an energy source or service has been safely isolated.
- Authorise work to proceed only once isolation is confirmed.
- Control the safe return to service afterwards.
- Prevent unexpected start-up or release of stored energy.
Who completes it
- An authorised, competent person carries out and confirms the isolation.
- The person doing the work confirms they understand the isolation.
- The employer decides who is authorised to isolate and to work.
- It is the employer’s responsibility to control isolation safely.
When it is used
- Before work where unexpected energy or movement could cause harm.
- On electrical, mechanical, hydraulic, pneumatic or fluid systems.
- Whenever the employer’s process requires controlled isolation.
Typical fields
- The equipment or system and the points isolated.
- How isolation was achieved and proved, and locks or tags used.
- Who isolated it, who authorised it and the time.
- The work permitted while isolated.
- Steps and sign-off for safe return to service.
- Example fields only — adapt to the system and the applicable law.
Common mistakes
- Isolating without proving the system is actually dead or safe.
- No locks or tags, so isolation can be removed by others.
- Unclear authority over who may return it to service.
- Returning to service without confirming the work is complete and safe.
Document workflow
An isolation permit form sits within the permit-to-work and task chain: it commonly follows the risk assessment and is required before the relevant work or task briefing begins, and it links to the job card and the sign-off that confirms safe return to service. It controls a specific hazard that other documents reference.
See the related documents below for what is commonly used with an isolation permit form.
Retention (high level)
Permits are usually kept for a period set by the employer so the control of the work can be evidenced. This page does not state a required period — confirm with the applicable law and the official authority.
Completing and sharing as a PDF
Isolation permits are often completed and stored as PDFs with the work records. Exporting to PDF supports the record; it does not make the permit official or guarantee compliance.
Employer checklist
- Ensure isolation is carried out by an authorised, competent person.
- Require isolation to be proved, locked and tagged.
- Make authority over return to service clear.
- Confirm work is complete and safe before re-energising.
Worker notes
- Do not start until isolation is confirmed and you understand it.
- Never remove someone else’s lock or tag.
- Confirm the work is complete before return to service.
Country considerations
Requirements for safe isolation and control of energy vary by country and system, and the official authority differs. This page is general and high-level — not a statement of any country’s law and not legal advice.
Confirm current requirements with the official authority for your country and a qualified professional.
Who is responsible
The employer is responsible for safe systems for isolating energy, for the competence of those involved and for compliance. This page is an educational overview with a template example; it does not determine what your permit must cover and does not transfer responsibility.
