Lessons Learned - Dry Well Transducer Installations are Susceptible to Inadvertent Removal; Disposal of Contaminated Waste
Year: 1991
Abstract: Description of Driving Event:
A hypergol technician erred in the removal of a temperature transducer from a 3-inch hypergol line at the "Pad A" fuel farm, resulting in a major fuel spill and hypergol burns to himself. The installation design of the dry well and temperature transducer provides a means to remove the transducer from the system for replacement or calibration without having to "open" the fluid volume. The dry well installation design is inadequate to preclude an untrained technician or a careless technician from inadvertently removing the dry well from the hypergol propellant line by mistake.
