Previous: Restricted Access Procedure
General physical access to Hall C is restricted by a full time badge reader system. The badge
reader limits non-emergency hall access to those individuals on the approved access lists. The
Hall Leader and experiment Liaison Physicist maintain the data base, with input from the
experiment run coordinator, the Hall C work coordinator, Hall C safety warden and physics division
safety personnel. As a part of the general access control the Liaison Physicist working with the collaboration
management will collect names of those who state by signature that they have read and understood
the COO and ESAD.
The badge reader based security system is in addition to the engineering and administrative
controls discussed previously. Specifically, to gain physical access to the hall
requires the logical .AND. of all engineering based access control systems. If the hall is in a
"Restricted Access" or lesser state the maglock will release after a valid badge is scanned by
the badge reader. Each individual must scan his/her badge separately and all
entries and exits are logged. Badges and access privileges are assigned to individuals. Letting
individual(s) into the hall via a badge not assigned to them will be treated as the circumvention
of a laboratory safety system. Exceptions include formal prearranged and approved guided tours or
escorting of a visitor who has a RADCON issued dosimeter.
If the hall is in "Controlled Access" those seeking entry must also
request access with MCC (generally by the phone near the door) simultaneously with the badge
scanning to unlock the outer Hall C personnel door. The MCC cannot override the badge reader's
data base and a valid badge does not guarantee that the MCC will allow entry into Hall C. The
badge reader's data base of authorized individuals is not static and may be modified as
appropriate for the activities underway in the hall at that time.
