TCSY cooling hose damage
Greg / DavidH
At ~0930 we were notified that a cut to one of the TCSY cooling hoses had been observed, and despite there being no leaks, it was decided to remove the affected length of hose near the table enclosure feed-through (cut out). No sharp edges were noticed on this feed-through, however as a preventative measure some clean room tape was applied around this cut out and then also around the two hoses before reconnecting them up. The chiller was operated and no leaks were observed.
The cooling hoses to TCSX were also inspected and no damaged was found. However, as a preventative measure, clean room tape was also applied around these hoses where they passed through the feed-through. It was decided to not disconnect these hoses (to apply tape around the enclosure feed-through) since no damage was observed and disconnection within the enclosure could introduce water leaks.
