Fire Brigade
(1) Organization i
.
'
The total s+.ation fire brigade is composed of approximately 85 personnel from the Operation and Security staff.
The on duty shift fire captain is normally an Assistant Shift Supervisor and the remaining four fire brigade members are composed of security personnel.
The licensee is presently - recognizing the fire brigade membership to eliminate security personnel participation, j
The fire brigade will be made up completely of personnel from
'(
the operations staff. This transition is scheduled to occur in December 1987.
The inspector reviewed the on duty shifts for the months of September and October 1987, to verify that sufficient qualified fire brigade personnel were on duty to meet the provisions of the plant's Fire Protection Program. The inspectors identified that on several occasions during the months reviewed unqualified personnel were assigned fire brigade duty.
Two security personnel who were removed from fire brigade duty when security reduced it's participation in the fire brigade and did not participate in the required training and one security member was removed for health reasons; however, these personnel were assigned brigade duty in the recurity journal.
This is identified as Violation Item (413, 414/87-37-01), Unqualified
Personnel Assigned to Fire Brigade Duty.
