control of the workplace (e.g. in relation to the timing of the work) and notifying any other affected persons as appropriate
Isolation          * identifying the circuit(s) requiring isolation

                   * disconnecting active conductors from the relevant source(s), noting there may be multiple sources and stand-by systems/generators/photovoltaic systems as well as auxiliary supplies from other boards

                   * if a removable or rack out circuit breaker or combined fuse switch is used
                     it should, if reasonably practicable, be racked out or removed then locked open and danger tagged
Securing           * locking the isolating switch(es) where practicable or removing and tying back relevant conductors to protect the person(s) carrying out the electrical work
the isolation
Tagging            * tagging the switching points where possible to provide general information to people at the workplace
Testing            * testing to confirm the relevant circuits have been de-energised and any other relevant conductors in the work area
Re-testing         * for example, if the person carrying out the work temporarily leaves the immediate area, checks and tests must be carried out on their return to ensure that the electrical equipment being worked on is still isolated to safeguard against inadvertent reconnection by another person
as necessary
                   * for example, if a wire changes its status when cut, which can occur because it is lifted from earth.

The effectiveness of isolation procedures relies on:
    * isolation points being readily available/accessible and being suitable for the type of isolation (switching) being conducted
    * the necessary hardware
    * having isolation procedures documented and accessible to electrical workers in the workplace
    * the provision of instruction, information and training of electrical workers involved with the electrical equipment
    * appropriate supervision to ensure safe work procedures, including isolation procedures,
      are followed.
Safe isolation procedures (including the use of locks and tags discussed below) should be developed in consultation with relevant workers. If the workers are represented by a health and safety representative, the consultation must involve that representative.

6.1              Securing the isolation
Regulation 156 A person conducting a business or undertaking must ensure that electrical equipment that has been de-energised to allow electrical work to be carried out on it is not inadvertently re-energised while the work is being carried out.
For work on low voltage electrical equipment or circuits, ensure that the correct point of isolation
is identified, an appropriate means of isolation is used and the supply cannot be inadvertently
re-energised while the work is carried out.
A fundamental principle is that the point of isolation should be under the control of the person
who is carrying out the work on the isolated conductors.
Tagging systems should also be used at the point(s) of isolation where possible for general information.
The isolation should
