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.

Everybody working on the equipment must put their own padlock on the
isolation point.
