NOTE: One or more of the team members may gather this data;
however, care should be taken to insure some degree of
independence (i.e., at least one member should be designated as
the "first" party and a second member designated as the "second"
party (independent) verifier for each component).
During the walkdowns, check the accuracy of the P&IDs to ensure
that the functional relationships are correctly represented and that
all components are accurately depicted. Annotate the drawings, as
appropriate, to show the as-found configuration and retain the
original for review and processing.
Perform the second party verification of the component nameplate
data and P&ID. Both the first party and the second party verifier
will sign the completed CCD sheet and P&ID, as appropriate.
NOTE: The objective of the second party verification is to ensure,
by direct observation that the correct data is obtained. For
example, if a valve is located overhead and access to the
component nameplate is by ladder, both team members will climb
the ladder to verify the information. Only one person going up and
calling down to the other is not considered a second party,
independent verification and is therefore unacceptable for the
purposes of this step.
During the walkdowns, general facility material and housekeeping
conditions should also be observed and any irregularities or
unusual conditions should be reported in the comments/remarks
section of the CCD. Examples of what to look for are as follows:
Obvious physical damage to equipment
Missing or illegible tags
Loose, bent, or missing supports and/or anchors
Valve packing glands "bottomed out" or unsymmetrical
Leaks e.g., water, oil, steam, etc.
Missing, bent, or broken valve handwheels
Missing or loose cover plates
Gagged relief valves
Unterminated cables showing bare wire
Unauthorized temporary modifications
If the documentation becomes contaminated, the information can
be transferred to non-contaminated documents and verified
