by vacuum group. The pump was making more noise than usual.
|
It seems the exhaust line is blocked which caused pressure to build up and eventually forced the exhaust tube off RP2 as RP1 was roughing down the vacuum chamber.
Vacuum group has been notified and will ask plant group to investigate.
Plant group has removed the blockage. Exhaust lines are reconnected to the roughing pumps. |
