This module is applicable only to areas that are required to adopt a process for securing points of disconnection to form points of isolation (a SIP process) and all future sections of electrification of Network Rail infrastructure.

The requirements of this module are applicable to Network Rail personnel and to Network Rail’s contractors.

This module does not include requirement for the following:

• Work on or about Network Rail controlled infrastructure equipped with the 1500V d.c. overhead line system (Sunderland Metro System Operating Area –Module Z).

Purpose

This module defines the requirements for securing points of disconnection, creating points of isolation, when implementing an Earthed Isolation.

This module combines relevant local Supplementary Isolation Processes (SIP) that have been implemented into one process and provides a consistent securing process for all future applications.

The requirements include the specific rules and procedures to be followed so that a sufficient documented safe system of work is prepared and implemented that complies with the Electricity at Work Regulations 1989, specifically Regulation 12.
