Previous: Controlled Access Procedure
Restricted Access is used when the hall will be open for an extended
period of time or
a large group will enter to work. To drop the hall to the
Restricted Access state, first
notify the MCC that you wish to open the hall in the Restricted Access
state. The MCC will
drop the hall status to Controlled Access and send an ARM to survey the
hall. Before anyone
can enter the hall, the ARM will carry out a radiation survey and post
radiation areas. The hall is
placed in Controlled Access during the survey to ensure that no one enters
before it has been
completed. Upon completion of the survey and posting of radiation areas,
the ARM will leave
the hall and notify the MCC that they can drop the hall state to Restricted
Access. With the hall
in the Restricted Access state, anyone with the appropriate training may
enter and work. The
key- release procedure is not required.
To return the hall to Beam Permit from the Restricted Access state, a
full inspection must
be carried out. This is begun by setting all equipment to its operating
state (following the Hall C
checklist) and then clearing all workers out of the hall. Next, a request
is made to the MCC to
arrange a sweep of the hall and to restore the Beam Permit state. The MCC
will send over an
ARM and set the hall status to Sweep. The ARM will then sweep the hall,
verifying that
everyone is out. Following a successful sweep, the MCC can move the hall
through the
Controlled Access and RF Permit states to the Beam Permit state.
While working in the hall you must observe all posted radiation areas.
Remember, work
inside a radiation area requires that you obtain an approved radiation
permit. You must also
observe the ``two-man" rule, and pay attention to the alarms.
