Label Placement - s1044cn10037

DOE-STD-1044-93

LABEL PLACEMENT

Labels should be placed on or near the components being identified in a manner that clearly

associates the label with its respective component and removes any ambiguity. Labels on control

panels should be consistently placed above, below, or on components so that the operator is

conditioned to finding and identifying information accurately. However, even when labels are

placed consistently above or below components, the results can be confusing, as shown in Figure

C-1.

Figure C-1. Labels evenly spaced between components.

To accurately identify the correct label with each component in the portion of the control panel

illustrated above, the operator would be required to search for indications of the labeling system

used, by checking the top of the panel, the bottom of the panel, or a separate legend. This

increases the chance of identification errors.

Where control panels contain many rows or columns of equally spaced components and labels, the

facility can reduce the risk of misidentification by "connecting" the labels to the components they

identify using brackets or tie lines, as shown in Figure C-2.
