MCC 8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse onto the equipment?

Overhead light fixtures judged to be acceptable.

Adjacent masonry wall restrained at top indicating that the wall was designed to resist lateral loads. Therefore it is judged to be seismically adequate.9. Do attached lines have adequate flexibility to avoid damage?10. Based on the above seismic interaction evaluations, is equipment free of potentially adverse seismic interaction effects?Yes Yes Yes Other Adverse Conditions

11. Have you looked for and found no adverse seismic conditions that could Yes adversely affect the safety functions of the equipment?

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 the 50%of SWEL items requiring such verification)?

No 2. Is the anchorage free of bent, broken, missing or loose hardware?Yes 3. Is the anchorage free of corrosion that is more than mild surface oxidation?

Yes 4. Is the anchorage free of visible cracks in the concrete near the anchors?Yes 5. Is the anchorage configuration consistent with plant documentation? (Note: This question only applies if the item is one of the 50% for which an anchorage configuration verification is required.)

Not Applicable

Viewed 5 of 9 anchors (all in front). Remaining anchors could not be viewed due to cabling and limitation on access. Anchors viewed matched documentation.

Thus it is reasonable to conclude that the anchors match plant documentation without further verification.

Duct stiffeners modified to provide clearance to cabinet. Top of 901-33 tied to adjacent cabinet (901-47).
