scope:

The locks and keys covered by this process include all those used to access signalling and telecommunications operational equipment. This includes any special order lock types configured to accept operational keys.

Purpose

There is a need to control the issue of keys allowing access to operational signalling and telecoms equipment so that only those competent to work in the vicinity of such equipment can access it. This is so that risk to the operational railway is minimised. This procedure explains the process that has been agreed between Network Rail and Unipart Rail to control the issue of S&T safety locks and keys by Unipart Rail.

The principle behind issue of keys to any party is that they are either a Network Rail employee requiring access to operational equipment as part of their duties or they are a contractor working on behalf of Network Rail with similar needs. In both instances keys shall only be issued to employees for the duration of time that they have duties requiring such access. Thus Network Rail contract managers shall arrange that keys are returned to Network Rail by a contractor at the end of a contract. Network Rail line managers shall arrange that keys are withdrawn from any individual leaving the company or transferring to a role within the company which no longer requires operational access.
