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)?
- 2. Does anchorage of equipment in the area appear to be free of significant Yes degraded conditions?
Minor lack of thread engagement in some anchorages judged 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 appears to be inside acceptable limits)?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)?
- 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 pipe well-supported and judged to be acceptable.
