Note: No exceptions from re-entry control other than those
listed above are authorized. Recommendations for exception from
re-entry control will be considered on a case-by-case basis by
the SCA. When entering systems under a REC exemption normal

C.1.2.2 Energy Control (Lockout/Tag-Out). Lockout/Tag-out
are (1) in need of maintenance or repair, or (2) define REC
boundaries and are not to be operated while the REC is open
(i.e., work in progress). Commands must develop suitable
lockout/tag-out procedures to control energy during maintenance
or servicing of equipment that meet the following requirements

Command instruction that clearly defines Lockout/Tag-
out procedures to be used for the unmanned pressure test facility
Both Lockout/Tag-Out devices shall indicate the
identity of the employee applying the device, cognizant shop of
code, telephone number where the employee can be reached during
working hours, his/her supervisor, date applied, and the machine,
equipment or system component that is deenergized.
C.1.2.3 Supporting Documentation/Objective Quality Evidence.
Objective quality evidence (OQE) is supporting documentation that
enables verification of installed components and raises
confidence in the installation. For UPTFs the major area of
concern is the primary pressure boundary. Pressure vessels, hull
penetrators, fittings and piping up to and including the hull
isolation valve, soft goods and repair kits, are examples of
components requiring OQE. OQE ranges from ASME code
documentation, level of cleanliness documentation, soft goods
packaging, and certificates of conformance (COC) from
manufacturers verifying part or kit numbers.
