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