on any electrically operated equipment it is essential
that measures be taken to prevent the equipment
operating.

This can only be done by isolating the equipment at its power source.

Electrical isolation can only be achieved by breaking the electrical contacts feeding the
equipment – these may be housed in an electrical panel feeding only that piece of equipment,
or the panel may feed more than one piece of plant.

All isolation handles are fitted with a device that allows the handle to be locked in the contactor
open (equipment isolated) position.

To prevent removal of isolation while you work on the equipment, you must ensure that you
have locked off the equipment and the key remains on your possession.

Do not work on equipment unless:
• You have securely isolated all of the equipment in your

working area using a personal lock

• You have checked that the right pieces of equipment

have been isolated

• Any stored energy has been safely released

• Equipment that could move has been secured.
