Saferoad MEGARAIL - Health and Safety; Design Requirements; Set Back

5 Revision 33 October 2022
Highway works Volume 1 clause 104. Sector Scheme 10B training is
available from SAFEROAD’s Lantra Awards approved training centre.
SAFEROAD’s training policy extends to anyone installing MegaRail from
outside of the UK who already has MegaRail training and therefore these
erectors must also have the LANTRA basic training for safety barriers and
hold a Blue, Gold or Black CSCS / FISS card. For details of available
training contact SAFEROAD. (Company contact details on page 28)
1.6 Health and Safety
It is the installer’s responsibility to ensure that all necessary safety
procedures are in place and implemented at all times. The site specific
conditions and restrictions should be assessed and a risk assessment,
method statement and lift plan produced by the installation company for the
specific site. All endeavours must be used to ensure that no one is injured or
put at risk during the installation, repair, inspection or maintenance of the
MegaRail VRS systems.
2. Design Requirements
The installation, inspection and repair of the MegaRail family of products
must comply with the requirements of The Specification for Highways Works
series 400, CD377 Requirements for Road Restraint systems, CD127, EN
1317 and SAFEROAD product specifications. It is important to note that
whilst product specification is constant, the requirements of Highways
Authorities across Europe will have differing constraints. This manual only
takes cognisance of the requirements in the UK.
2.1 Set Back
Set Back should normally be as described in the table below, but the
Design Organisation may use further relaxations in accordance with the
notes on the table which is taken from CD127 2.24
If
both set back and working width cannot be achieved, we recommend that
set back should be reduced and working width maintained.

(iii)
Relaxation to 1000mm at existing roads with physical restraints (e.g. a structure)
where it would be difficult to provide the desirable value.
Relaxation to 450mm will be permitted where it is considered necessary to position
the VRS away from the edge of an existing embankment in order to provide support
to the foundation.
