description abstract	Description of Driving Event: The LH2 system maintenance includes a monthly vacuum reading in the annulus space in the overhead vacuum-jacketed (VJ) high point bleed and LH2 fill lines. Access to the read-out ports in the GH2 fill line on side 1 of the MLPS is precarious. There are not adequate tie-off points for body harness and lanyards. The readout ports are 10-12 feet above the floor grating. If a technician uses a ladder for access, or climbs on existing structures to make the reading, he/she is within inches of exterior handrails and above them. This places him/her about 40 feet above the vab floor or the pad surface.
