Lessons Learned - LH2 Vent Line Valves
Year: 1992
Abstract: Description of Driving Event:
The LH2 vent system valves are located in the flare stack area of Pads A and B. The valve control handles are elevated between 8 and 10 feet above ground. Operational personnel are frequently required to climb up on the 12", 14", and 18" vent lines to operate the valves. The use of safety belts/ harnesses is not practical in this situation since the tether-off point is not available. Also, use of a pipe as a work platform is not in keeping with good safety practice.
