WARNING
There is a danger from false feeds, residual (capacitive) charge, induced
voltage, back feeds, lightning or accidental energisation.
Generally, the status of OLE falls into the following categories:
Live (energised and dangerous): When a potential difference exists between the
equipment and earth.
De-Energised: The status of OLE after Circuit Breakers and/or Isolators feeding an
electrical Section have been opened and are electrically separated from the source.
No earths are applied and no OLE Permit to Work Issued.
Within an OLE Permit to Work: The status when OLE is disconnected and
separated from all sources of electricity supply in such a way that this disconnection
and separation is secure. Earths have been applied and an OLE Permit to Work
describing the safe limits of work, has been Issued.
