COOLER, CUBICLE -2A CS PMP RM COOLER Interaction Effects 7. Are soft targets free from impact by nearby equipment or structures?

Tube in contact with cooler brace. Tube is flexible, brace is rigid; judged to be acceptable.

8. Are overhead equipment, distribution systems, ceiling tiles and lighting, and masonry block walls not likely to collapse onto the equipment?
9. Do attached lines have adequate flexibility to avoid damage?Cooler is restrained to wall; thus, there are no concerns regarding the relative flexibility of the cooler and attached piping.10. Based on the above seismic interaction evaluations, is equipment free of potentially adverse seismic interaction effects?Yes 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?
