thin wall tubing are several different requirements for the
barrier
planks associated with post and plank systems
tubular

steel
thin wall tubing, rolled and welded pipe
The following explains the requirements and how they may be met using
barrier
planks which are red and
steel
thin wall tubing white and manufactured in fully retro-reflective materials

Barrier planks are required to carry out three functions :- As a traffic
barrier
tubular

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

As a pedestrian

Pedestrians must be separated from the works
steel

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
steel
thin wall tubing detected by partially sighted people, but red and white is one of the acceptable combinations

All
barrier
s facing vehicular traffic should be of the fully retro-reflective red and white form

Red

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
steel
thin wall tubing of
barrier
planks in portable fencing systems: The traffic
barrier
is not needed if the works are protected by a conspicuous vehicle

Pedestrian
barrier
systems must be rigid enough to guard pedestrians
steel

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
steel
thin wall tubing 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
steel
thin wall tubing to cross from the opposite side,
barrier
s on the traffic stream side of the works area do not need the tapping rail

In these circumstances, on an unrestricted road, the
barrier
on
steel
thin wall tubing the traffic stream side can be replaced with an additional row of cones.Use pedestrian

s to mark out any temporary footway

You must always use a rigid
barrier
to protect pedestrians from
steel
