Educational guides on how workplace documents fit together — which document is typically completed before another, what is used alongside it and what follows.

What an equipment isolation and lockout workflow is
An equipment isolation and lockout workflow is the chain of documents an employer uses to make equipment safe before maintenance — isolating energy sources, locking them off and confirming zero energy before work begins. It links the isolation risk assessment, the isolation permit, the lockout-tagout record, the maintenance under isolation and the verified return to service.
This page is an educational overview of how those documents typically connect. It does not define your isolation procedure — the employer is responsible for ensuring energy sources are safely isolated by competent people, under the applicable law.
Why these documents connect
Maintenance on equipment that can start or release stored energy is a major cause of serious harm, so the documents control isolation tightly. The risk assessment identifies the energy sources; the permit authorises the isolation; the lockout-tagout record shows what was locked off and by whom; the work proceeds under isolation; and a verified return to service removes locks only when it is safe.
Connecting the documents means equipment cannot be re-energised while someone is working on it, and re-energisation only happens after a deliberate, verified return to service.
The typical sequence
- Required before: an isolation risk assessment and an isolation permit identify and authorise the isolation.
- Used with: a lockout-tagout record captures what was isolated, locked and tagged.
- Completed after: the maintenance is done under isolation and a verified return to service removes the locks.
- Escalation: any doubt about isolation stops the work until confirmed.
- These are example steps only — adapt the sequence to your equipment and the applicable law.
When the chain runs
The chain runs before any maintenance on equipment that can start or release stored energy, and continues until a verified return to service.
It also runs whenever the scope of a job changes in a way that affects the isolation.
Who owns each step
- The employer owns the isolation procedure and competence.
- An authorised person isolates and applies the lock and tag.
- The maintainer works only under confirmed isolation.
- A supervisor verifies return to service before locks are removed.
Common mistakes
- Starting work before confirming zero energy.
- Locks or tags removed by someone other than the person who applied them.
- No record of what was isolated.
- Stored energy (pressure, springs, gravity) not released.
- No verified return to service before re-energising.
Records & retention (high level)
Employers generally keep isolation permits and lockout-tagout records for as long as relevant and for a period afterwards, in line with their obligations and data-protection duties.
This page does not state a required period — confirm retention with the applicable law and the official authority.
Sharing the workflow as a PDF
Isolation permits and lockout-tagout records are commonly stored as PDFs so the isolation history stays together and can be shared or audited. Exporting to PDF supports the record; it does not make the isolation official or guarantee compliance.
Employer notes
- Identify all energy sources, including stored energy.
- Allow only authorised, competent people to isolate.
- Ensure locks are removed only by the person who applied them.
- Verify return to service before re-energising.
Worker notes
- Work only under a confirmed, locked-off isolation.
- Apply and remove only your own lock and tag.
- Confirm zero energy before starting, including stored energy.
- Stop if you are unsure the isolation is complete.
Country considerations
Safe isolation and lockout practice and the official authority vary by country. This page is high-level and general — it is not a statement of any country’s law and not a guarantee that a process or form is valid anywhere.
Always confirm the current requirements with the official authority for your country and a qualified professional.
Who is responsible
The employer is responsible for ensuring equipment is safely isolated for maintenance by competent people, and for compliance. This page is an educational overview with a template example; it does not set the procedure, does not make a workplace compliant and does not transfer responsibility.
