Instructions for Completing Checklist This checklist may be used to document the results of the Seismic Walkdown of an item of equipment on the SWEL. The space below each of the following questions may be used to record the results of judgments and findings.

Additional space is provided at the end of this checklist for documenting other comments.Anchorage 1. Is anchorage configuration verification required (i.e., is the item one of No the 50% of SWEL items requiring such verification)?

2. Is the anchorage free of bent, broken, missing or loose hardware?

Yes Supported off the wall 3. Is the anchorage free of corrosion that is more than mild surface Yes oxidation?

4. Is the anchorage free of visible cracks in the concrete near the Yes anchors?5. Is the anchorage configuration consistent with plant documentation?

Not Applicable (Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)

6. Based on the above anchorage evaluations, is the anchorage free of Yes potentially adverse seismic conditions?
