Safe Isolation: The Core Electrical Safety Sequence

Safe isolation is a safety-critical procedure. VoltMate's visual sequence is for learning and revision; real work requires competent practice, the correct equipment and the applicable procedure for the installation and workplace.

1

Identify and isolate

Identify the correct circuit and isolation point, then operate the correct means of isolation rather than relying on a label or assumption alone.

2

Secure the isolation

The isolation must remain under control so the circuit cannot be inadvertently re-energised while work is taking place.

3

Prove, test, re-prove

A suitable voltage indicator is proved before the dead test, used to test the relevant conductor combinations, then proved again so a tester failure is not mistaken for a dead circuit.

Key ideas

Isolation is more than switching off
The voltage indicator is proved before and after use
Follow the applicable safe system of work
