required for normal operation. Functional testing prior to startup, and periodic surveillance
during operation, may be required for equipment that is subject to technical safety
requirements. Techniques for verifying component positions and additional information
concerning verification requirements are contained in DOE Order 5480.19, Chapter X,
When alignment checklists have been completed, they should be signed and approved by
the operations supervisor. Completed checklists serve as documentation of the system and
equipment status and provide a basis for verification. They should be retained in an
accessible location until the next time the checklist is completed, at which time the
superseded checklist may be filed.
A system to track deviations from the normal alignment should be established. One method
commonly used for this purpose is the status board. Status boards typically contain a
graphic or schematic representation of the system, or a listing of system components. When
status changes are made, the status board is annotated to indicate the current status of
equipment. The status board (or other tracking system) should be promptly updated when
a change to system or equipment alignment occurs. In addition, all status changes should
be documented in the narrative log. DOE Order 5480.19, Chapter XI, "Logkeeping"
provides additional information for maintaining narrative logs.
The status board or other tracking system should be controlled by the operations supervisor
and designated system operators. The status control information recorded in the narrative
logs and reflected in updates to the tracking system should be incorporated into the
operations turnover process. DOE Order 5480.19, Chapter XII, "Operations Turnover,"
identifies elements of an effective turnover.
4.3 Equipment Locking and Tagging
Locking and tagging, or lockout/tagout, is a program for removing equipment from service
and establishing administrative controls to prevent its operation. It is used to ensure the
safety of workers performing maintenance or testing, and may be used for other purposes
