Contractor Isolation Confirmation Form

An educational library of workplace documents — purpose, who completes them, when they are used, typical fields, common mistakes and how they connect. Linked to workplace safety, workplace training, occupations, industries and employment documents. Informational only — template examples, not legal advice or official documents; employers remain responsible and using a document does not guarantee compliance.

What a contractor isolation confirmation form is

An isolation confirmation form records that the relevant energy sources — electrical, mechanical, pressure, stored energy — have been isolated, locked or tagged where required, and verified, and that the contractor has confirmed they understand the isolation before starting.

This is an educational overview with a simplified example. It is not an official template and does not itself isolate anything — the employer controls its isolation and lock-off arrangements.

Purpose

• Record that energy sources have been isolated and verified.
• Confirm locks or tags are applied where required.
• Confirm the contractor understands the isolation.
• Support safe work on or near previously energised equipment.

Who completes it

• The competent person who carries out the isolation.
• Confirmed by the contractor relying on it.
• The employer decides who is authorised to isolate.
• It is the employer’s responsibility to control isolations.

When it is used

• Before work on or near energised equipment or systems.
• When the isolation needs to be re-verified.
• At a handover where the isolation continues.
• Whenever the employer’s isolation procedure requires it.

Typical fields

• Equipment or system and the energy sources isolated.
• Isolation points, locks or tags applied.
• Verification that isolation is effective.
• Person isolating and contractor confirmation.
• Date, time and any reinstatement conditions.
• Example fields only — adapt to your systems and the applicable law.

Common mistakes

• Relying on an isolation without verifying it.
• Missing a stored-energy or secondary source.
• No record of who isolated or who confirmed.
• Reinstating energy without checking everyone is clear.

Document workflow

Isolation confirmation usually accompanies a permit to work and the safety briefing, after the method has been accepted and before work begins on the equipment. It feeds the permit record and is relied on at handover and reinstatement.

See the related documents below for what is commonly required before and used with an isolation confirmation form.

Retention (high level)

Isolation records are usually kept with the permit and the work records for a period defined by the employer and any applicable rules.

This page does not state a required period — confirm with the applicable law and the official authority.

Completing and sharing as a PDF

Isolation confirmations are commonly completed and stored as PDFs with the permit. Exporting to PDF supports the record; it does not isolate anything or guarantee compliance.

Employer checklist

• Ensure only authorised, competent people isolate.
• Require verification, not just application, of isolation.
• Account for stored energy and secondary sources.
• Control reinstatement so no one is at risk.

Contractor notes

• Confirm the isolation before relying on it.
• Do not remove or bypass locks or tags.
• Make sure everyone is clear before reinstatement.

Country considerations

Expectations for isolation and lock-off of energy sources differ by country, and the official authority differs. This page is general and high-level — not a statement of any country’s law and not a guarantee of validity.

Confirm current requirements with the official authority for your country and a qualified professional.

Who is responsible

The employer is responsible for safe isolation and lock-off arrangements and for compliance. This page is an educational overview with a template example; it isolates nothing and does not transfer responsibility.
