    Hi Paul

    We apply a standard network lock (not individual or personal locks)under direct instruction from the Control Room, where practicable. Due to automation of the network and subsequent remote operation from the Control Room, there are less actual issuer-applied locking activities taking place.

    This is in conjunction with a signed and dated ‘DNO’ tag.

    Due to the remote operations as mentioned above, we are looking at making our DNO tags more visible.

    We have a different tag for out-of-service equipment, and for installation-related activities.
