Replacing Labels

4.4.1

Identifying Lost or Damaged Labels

Facilities should establish procedures to ensure that missing, damaged, or

incorrect labels are promptly replaced. Since labels may be removed or

misplaced during maintenance activities, facility procedures should require

operators to verify labels when the equipment is returned to service.

Operators performing component alignments or rounds should verify that

labels are present, readable, and undamaged. A column can be added to valve

line-up sheets or system alignment checklists to ensure that label condition

and accuracy are checked during system line-ups. Checks may also be added

to preventive maintenance procedures (PMs), or other procedures, to ensure

that components are correctly labeled.

Operators should watch for use of informal labeling methods (e.g., black

marking pen) as these may represent places where formal labeling should be

applied.

4.4.2

Providing New Labels

The operations supervisor (or other designated management authority) should

review and approve all requests for new or replacement labels. Labeling

requirements should also be evaluated during the planning of design changes

or temporary modifications. Conflicts involving component identification

(e.g., inconsistent component numbers or names used in procedures or

drawings) should be resolved before labels are approved.

If a new label cannot be immediately provided, a temporary label should be

installed until a correct permanent label can be obtained. All labels should be

installed by personnel knowledgeable of the components and their function in

the system to prevent inadvertent equipment operation during label

installation, and to prevent interference with normal component operation.

The attachment of temporary or permanent labels should be independently

verified to ensure that the label is properly attached to the correct component

and all the label information is correct.
