The PO must ensure:
that the Locations of Lookouts and the visibility conditions give Lookouts enough
Sighting Distance of approaching Rail Traffic;
that Lookouts have Effective Communication with Workers and are equipped with an
audible Warning device;
when working in Bidirectional locations where rail traffic can approach from either
direction:
o a minimum of one (1) Lookout is placed either side of the Worksite and a
minimum of five (5) seconds reaction time can be achieved when calculating the
Sighting Distance; or
o a single Lookout is placed to provide warning for both directions and a minimum
of 15 seconds reaction time can be achieved when calculating the Sighting
Distance.
that when Rail Traffic approaches, Lookouts can warn Workers in time to allow them
to:
o react to the Warning of the approach of Rail Traffic; and
o move themselves and their equipment to a Safe Place before the Rail Traffic
arrives.
