Lessons Learned - The Oxygen Vent System.
Year: 1992
Abstract: Description of Driving Event:
The vacuum servicing units provide the capability to evacuate the PRSD tanks and the relief line. The unit consists of a skid mounted frame, electrical and fluid control panels and an electric motor driven vacuum pump. If the vacuum servicing unit is left connected to the suction line, inadvertent opening of manual valve A81992 could subject the pump to 935 psig from the cryo valve panel. This is beyond the unit's capability and could expel pump oil through the vent system.
