AUXBFloor El.Room 4288Manufacturer, Model, Etc.Instructions for Completing ChecklistThis 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 ofjudgments andfindings. Additional space is provided at the end of this checklist for documenting other comments.Anchoragel. Is the anchorage configuration verification required (i.e., is the item one of the 50Yo of SWEL items requiring such verification)?

This panel is part of a line-up that includes D2N and YRF4. Each panel is anchoredto the concrete withfour 3/4" diameter anchor bolts.2. Is the anchorage free of bent, broken, missing or loose hardware?

3. Is the anchorage free of corrosion that is more than mild surface oxidation?4. Is the anchorage free of visible cracks in the concrete near the anchors?5. Is the anchorage configuration consistent with plant documentation?(Note: This question only applies if the item is one of the 50o/oforwhich an anchorage configuration verification is required.)SQUG Calculation C-CSS-YV4 indicates four 3/4" anchors and that MOD-95-0034 resolves a pounding concern.Anchorage and implementation of MOD-95-0034 were confirmed during walkdown 6. Based on the above anchorage evaluations, is the anchorage free of potentially adverse seismic conditions?
