12 - ANNEX - SUMMARY OF TECHNICAL DEVIATIONS BETWEEN THIS STANDARD AND IEC 621-5

Sets out requirements for the normal operating procedures which should be carried out to ensure the safety of personnel. Includes measures relating to control of access to operating areas, work in the vicinity of exposed live parts, and the movement of vehicles and machinery in the vicinity of overhead lines. Technically equivalent to IEC 621-5.

This standard specifies the normal operating procedures which should be carried out to ensure the safety of personnel. These procedures may be varied in certain circumstances where a planned operation is performed under controlled conditions.NOTE: Attention is drawn to the fact that the requirements of Regulatory Authorities may differ from the requirements specified in this standard.
