C.1.2 Re-Entry Control (REC). REC is a system for maintaining
positive control of work performed within the certification
boundaries of the unmanned pressure test facility.
The system
provides for monitoring and documenting the following:
a)
What system worked on
b)
Why work was required
c)
What work was accomplished, including safety
precautions, materials and components used, re-test
requirements, test data and supporting documentation
d)
Who did what work (Craftsman)
e)
Who authorized and accepted the work (Facility Manager
or his designated representative.
f)
Who maintains documentation (REC Supervisor)
When any maintenance or work is performed which breaches the
certification boundaries of the UPTF the REC supervisor must
first initiate a REC. This is accomplished by filling out the
REC log, completing a REC sheet obtaining authorization from the
facility manager (or designated representative). The necessary
work or maintenance can now be performed on the facility. Upon
successful test completion, the REC sheet is completed and all
applicable maintenance check-off sheets, inspection records,
testing records, and fabrication records are attached to the REC
sheet. Once the closure complete signature is obtained from the
Facility Manager, the REC can then be closed out by the REC
supervisor by placing the REC package on file and completing the
REC log entry.
Under Normal circumstances the unmanned pressure test facility
should not be operated with an open REC. However, if the system
or Sub-system affected by the REC can be isolated to ensure the
safety of operators, craftsmen, and property, the Facility
Manager may authorize operation of the Unmanned Pressure Test
Facility.
C.1.2.1 Exceptions to Re-Entry Control. Certain UPTF require
frequent entry into the certified boundary for routine operations
or maintenance actions to enable mission accomplishment. Any
operational controls believed to be adequate in lieu of re-entry
control or controlled work procedures should be submitted to the
SCA for approval. Examples of actions not requiring a REC are:
a) Normal operation of access hatches, pressure boundary
doors or similar operations covered by an operating procedure
(OP).
b)
Removal of portable gas flasks for charging.
