Panel Walkdown

DOE-STD-1038-93

4.3.1 Panel Walkdown

Prior to assuming responsibility for the work station, the on-coming person should

personally verify the status of important system operating parameters. Walkdowns of

appropriate instrumentation and control panels, especially those relating to safety

systems, should be conducted at each work station. The purpose of a panel walkdown

is to determine facility status through observing system lineups, switch positions,

lighted annunciators, chart recorders, and status lights.

On-coming and off-going persons should conduct the walkdown together during the

turnover. A discussion of work station status, trends, and potential problems should

occur during this walkdown. The turnover checklist, if specified to be used by the

work station, should be used as an aid in this discussion. As a minimum, the

discussion should be focused on items observed during the walkdown, for example:

C Status of safety-related equipment

C Running equipment

C Inoperable equipment, including instrumentation

C Technical safety requirements, including surveillance requirements

C Reasons for actuated alarms or annunciators

C Tagged equipment, including any surveillance/equipment work in progress

C Abnormal equipment and component configurations.

It is the responsibility of the off-going person to communicate all pertinent information

about the work station to the on-coming person during the walkdown. The on-coming

person should inquire about unfamiliar lineups, positions, indications, and tags

observed during the walkdown.
