There must be a PO present at the Worksite for the period of work, except if the ASB is
used to allow road vehicles to directly cross the Track or where station staff are
required to access the Track. In these circumstances the Train Controller may apply
ASB and assume the role of the PO.
If Authorised by the Train Controller, the PO must remove and safeguard the Crank
Handle.
A PO must:
make sure that work in the Danger Zone does not begin before the required safety
measures are in place;
be responsible for the Protection of Workers from Rail Traffic;
ensure the Worksite is for the shortest practical distance;
identify all entry points and the kilometre location of the limits of the Worksite;
make sure that the Worksite is protected against the entry of Rail Traffic;
inform all workers of the limits of the Worksite; and
tell Workers about the Location of Safe Places.
NOTE
A PO must be satisfied that other work will not interfere with Protection
duties.
