<br />
== Purpose ==<br />
<br />
To ensure electrical circuits are safely isolated and proven dead before any work is carried out.<br />
<br />
== Required Equipment ==<br />
<br />
* Approved Voltage Indicator<br />
* Proving Unit<br />
* Lock Off Device<br />
* Warning Tag<br />
<br />
== Procedure ==<br />
<br />
=== 1. Identify The Correct Circuit ===<br />
<br />
Confirm the circuit or equipment to be worked on and identify the correct means of isolation.<br />
<br />
=== 2. Inform Relevant Persons ===<br />
<br />
Advise the customer, occupier or any affected persons that the supply will be isolated.<br />
<br />
=== 3. Isolate The Supply ===<br />
<br />
Switch off the appropriate protective device or isolator.<br />
<br />
=== 4. Secure The Isolation ===<br />
<br />
Apply a suitable lock off device and warning tag to prevent inadvertent re-energisation.<br />
<br />
=== 5. Prove The Tester ===<br />
<br />
Verify the voltage indicator is functioning correctly using a proving unit.<br />
<br />
=== 6. Test For Dead ===<br />
<br />
Test between:<br />
<br />
* Line and Neutral<br />
* Line and Earth<br />
* Neutral and Earth<br />
<br />
Confirm no voltage is present.<br />
<br />
=== 7. Re-Prove The Tester ===<br />
<br />
Immediately re-test the voltage indicator on the proving unit to confirm it remains operational.<br />
<br />
=== 8. Commence Work ===<br />
<br />
Only once the circuit has been safely isolated, locked off and proven dead may work begin.<br />
<br />
== Important Notes ==<br />
<br />
* Never rely solely on switching off.<br />
* Never assume a circuit is dead.<br />
* Always use an approved voltage indicator.<br />
* Always prove, test and re-prove.<br />
* Maintain control of the key for any lock off device used.<br />
<br />
== JME Standard ==<br />
<br />
No electrical work shall commence until the circuit has been isolated, secured, proven dead and verified in accordance with this procedure.<br />
