5. MOBILE PLANT

Mobile plant is only permitted to be less than three (3) metres from Live OLE if controls
are implemented and a Vicinity Form is Issued for the specific task.
To calculate clearances, consideration must be given to such encroachment by any
part of the operator, any part of the machine or its load, or by anything affected by the
activity.
When applying for a Vicinity Form for work associated with mobile plant, the applicant
must include details of:
 the mobile plant make, size and registration number;
 proposed dates and times of work;
 the Location of proposed work;
 PRES name and contact details;
 restrictor chains, their certification date and minimum capacity (if chains are in use);
and
 names of Workers who will perform the work and Track Access Permit number.
The application for a Vicinity Form must also demonstrate that appropriate controls will
be in place.

The site-specific risk assessment must be performed. With appropriate controls in
place, the resulting level of risk that people, equipment or other objects will be less than
one (1) metre from Live OLE, must be acceptable.
If plant is fitted with electronic slew locks and/or restrictor chains, this must be noted in
the safe work method statement.
The PRES must also ensure that:
 the complete restrictor chain and securing device is a minimum of 2 x the machine’s
safe working limit or working load limit displayed on the mobile plant;
 the restrictor chain cannot be detached at any time whilst the mobile plant is in
operation;
 the restrictor chain is tested, tagged and Certified; and
 if plant is fitted with electronic slew locks and/or restrictor chains, that these are
detailed in the safety management plan and that their safe operation is
demonstrated on site before use.
The PRES is responsible for ensuring that the controls associated with the Vicinity
Form are implemented.
The Nominated Person (NP) who Issues the Vicinity Form must obtain confirmation
from the PRES that the controls stated on the Vicinity Form will be in place for the
duration of work for which a Vicinity Form is required.
The work must only occur while the PRES named on the Vicinity Form is on site. Each
Vicinity Form is Issued for a specific task and to a specific PRES and is not
transferable. If the conditions listed in the Vicinity Form cannot be met then there will
be a need to apply for a Permit to Work.
