This bulletin is issued to provide enhanced guidance around the lifesaving rule for 'test before touch' for 25kV Overhead Line Equipment (OLE).
A previous safety bulletin NRA 18/12 was issued in July 2017 which set out the 5 step process for test before touch on 25kV OLE.
Recent feedback from practitioners on site have highlighted a need to address concerns on the different ways 'Test before Touch' is being interpreted across the 25kV Network.
A revised application guide has been produced specifically for 25kV OLE titled "Never assume equipment is isolated – always test before touch".
This is available to download from Safety Central website (https://safety.networkrail.co.uk/wpcontent/uploads/2016/12/LSR-update-25kVoverhead-line-equipment-Test-Before-Touch-_06-02-2019.pdf).
This will be implemented for use by 30th June 2019.
The revised application guide will be incorporated into the existing application of the electrical lifesaving rules applied to electrical power assets (https://safety.networkrail.co.uk/wpcontent/uploads/2016/12/Application-of-theElectrical-Lifesaving-Rules.pdf).
