The nitrogen piping supplying purge to the 3 IFO storage containers has been relocated from above HAM 7, 8, & 9 to below the HAM chambers to allow for removal of the chambers when it becomes necessary. The purge was turned off for approximately 3 hours during this relocate and is now restored to the containers. The piping along the H2 output arm is also located below the chambers in order to facilitate removal of HAM 10 when necessary.

Some cable tray was also removed from the top of HAMs 7 & 8 for the purpose of removing HAMs.
