2. Scope
This document is limited to the type and installation requirements for all types of anti-climbing device, safety signs and
information labels required on overhead line supports up to and including 132kV.

This document shall be read in conjunction with Northern Powergrid policy document NSP/004/012 which provides
detailed information on the risk assessment of overhead lines and the recommended mitigation measures required.

This document has been designed to fully comply with ENA TS 43-90 Issue 6:2013.

To comply with the requirements of the ESQC regulations each overhead line needs to be classified in terms of the risk of interference.1. Different risk classifications must be assigned to different parts of the overhead line if the risks associated with that part of the line vary. Assessing whether the structure is climbable or not:-  As a general principle.5 m of a climbing aid such as an adjacent wall.5m centres and all lattice towers or masts must be regarded as climbable. a structure such as a single pole or portal structure with pole centres of more than 1. if there is a foothold free surface of 3 m above the point where a person can stand then the support may be regarded as not near to the climbing aid. The precautions must be selected to offer the best degree of deterrent against climbing taking account of the environment and the likelihood of interference from third parties. building.
