planks associated with post and plank systems. The following explains the requirements and how they may be met using
barrier
planks which are red and white and manufactured in fully retro-reflective materials. Barrier planks are required to carry out three functions
medical
:- As a traffic
barrier
. When a traffic lane is closed for works to take place, the regulations require this to be done with a retro-reflective red and white
barrier
plank placed across the lane. As a pedestrian
barrier
. Pedestrians must be separated from the works by a
barrier
which
medical
is conspicuous and mounted as part of a portable fencing system. Pedestrian
barrier
planks may be of several different contrasting colours; yellow, white or orange colours are best detected by partially sighted people, but red and white is one of the acceptable combinations. All
barrier
s facing vehicular traffic should be
medical
of the fully retro-reflective red and white form. Red and white
barrier
planks do not have to be used for pedestrian
barrier
s or tapping rails but, if they are, they must be retro-reflective .There are other points to note about the use of
barrier
planks in portable fencing systems: The
medical
traffic
barrier
is not needed if the works are protected by a conspicuous vehicle. Pedestrian
barrier
systems must be rigid enough to guard pedestrians from traffic, excavations, plant or materials. They must be placed with sufficient clearance to prevent pedestrians falling into the excavation and, when placed to create a
medical
temporary footway in the carriageway parallel to the traffic stream, must be protected by a row of traffic cones between the
barrier
and the traffic stream. Where long excavations are sited in situations where pedestrians are not expected to cross from the opposite side,
barrier
s on the traffic stream side
medical
of the works area do not need the tapping rail. In these circumstances, on an unrestricted road, the
barrier
on the traffic stream side can be replaced with an additional row of cones.Use pedestrian
barrier
s to mark out any temporary footway. You must always use a rigid
barrier
to protect
medical
pedestrians from traffic, excavations, plant or materials.
