How do you perform the safe isolation procedure?

The 'Safe Isolation Procedure' is a procedure carried out to ensure that you are working safely on electrical equipment.

Firstly, you isolate the power at the fuse board. It's best to switch each circuit off one by one starting furthest away from the main red switch (I'm not 100% sure why but its something to do with voltages). You then erect barriers and signs.

You then lock off at the main switch and remember to keep the key on your person.

After this you use a certified voltage tester (preferably a gs38) to check if the board is dead. Give the tester a thorough inspection check leads and probes and then use the proving unit to check it's not faulty. After this you then test at the board main L to main N, then main L to man E, then main N to main E (3 point test). You then test at your proving unit again to check testers not faulty and then commence work.
