O11.9.3 The supervisor, who is located in the closure control vehicle, should have a clear communication link with the appropriate control offices. The key personnel should also carry mobile phones to be used in the event of a communications failure. The procedure for dealing with a communications failure is dealt with in Section O11.21.
