Safer work starts with better knowledge.

Identify electrical, mechanical, hydraulic, pneumatic, thermal and stored energy.

Only authorised people should apply and verify isolation.

Define which equipment and connected systems are included.

Consider trapped pressure after the main supply is disconnected.

Control components that may fall or move under gravity.

Use the approved identified isolation points for the task.

Follow the site's personal lock and identification arrangements.

Verify the required safe state before work begins.

A stop button alone is not a secure isolation method.

Use a coordinated isolation system for multiple workers.

Maintain protection when teams or shifts change.

Agree isolation responsibilities with contractor personnel.

Prevent remote or automatic restart during the work.

Reassess isolation when the maintenance task expands.

Use the approved procedure for any required test or temporary energisation.

Restore equipment only through the authorised handback process.

Never remove another person's lock outside the formal exceptional process.
