AWC-Ul-24 Instructions for Completing Checklist This checklist may be used to document the results of the Area Walk-By near one or more SWEL items. 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.1. Does anchorage of equipment in the area appear to be free of potentially Yes adverse seismic conditions (if visible without necessarily opening cabinets)?

Pipe support at 1-2301-42 base plate has minor edge gap. Judged to be acceptable.

2. Does anchorage of equipment in the area appear to be free of significant Yes degraded conditions?

1-2304-3 switch box missing I of 4 anchors. Unistruts and anchors with minor corrosion.

Judged to be acceptable.

3. Based on a visual inspection from the floor, do the cable/conduit raceways and Yes HVAC ducting appear to be free of potentially adverse seismic conditions (e.g., condition of supports is adequate and fill conditions of cable trays appear to be inside acceptable limits)?Minor bends in hanger rods judged to be acceptable.

Several contacts between flexible items judged to be acceptable.

4. Does it appear that the area is free of potentially adverse seismic spatial Yes interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

Overhead light fixtures with slightly-open S-hooks not open enough for fixture to fall from hook. Judged to be acceptable.

5. Does it appear that the area is free of potentially adverse seismic interactions Yes that could cause flooding or spray in the area?Threaded fire piping, room heaters, and associated piping well-supported and judged to be acceptable.
6. Does it appear that the area is free of potentially adverse seismic interactions Yes that could cause a fire in the area?Covered oil waste can is judged to be acceptable.
7. Does it appear that the area is free of potentially adverse seismic interactions Yes associated with housekeeping practices, storage of portable equipment, and temporary installations (e.g., scaffolding, lead shielding)?

Ladder chained to rugged pipe at pipe support judged to be acceptable.

Two scaffolds in room are well-restrained.

AWC-Ul-24 8. Have you looked for and found no other seismic conditions that could Yes adversely affect the safety functions of the equipment in the area?Floor grating/gallery supports unanchored at some locations.

Walls and edge of slab restrain gallery/gallery laterally.

Judged to be acceptable.

Conduit near Valve 1-2301-6-MO missing support attachment judged not to be of seismic concern. Valve 1-2301-3-MO missing I of 4 support bolts. Seismic acceleration of basement is low and support is rgidly mounted. Judged to be acceptable.
