The following explains the requirements and how they may be met using
barrier
planks which are red and aluminum
fabrication
white and manufactured in fully retro-reflective materials

When a traffic lane is closed for works to take aluminum
fabrication
place, the regulations require this to be done with a retro-reflective red and white
barrier
plank placed across the lane

Pedestrians must be separated from the works aluminum
fabrication
by a
barrier
which 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 aluminum
fabrication
detected by partially sighted people, but red and white is one of the acceptable combinations

Red aluminum
fabrication
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 aluminum
fabrication
of
barrier
planks in portable fencing systems: The traffic
barrier
is not needed if the works are protected by a conspicuous vehicle

They must be placed with sufficient clearance to prevent pedestrians falling into the excavation and, when placed to create a temporary footway in the carriageway parallel aluminum
fabrication
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 aluminum

to cross from the opposite side,
barrier
